The Hornsby-Akroyd oil engine , named after its inventor Herbert Akroyd Stuart and the manufacturer Richard Hornsby & Sons , was the first successful design of an internal combustion engine using heavy oil as a fuel. It was the first to use a separate vapourising combustion chamber and is the forerunner of all hot-bulb engines , which are considered predecessors of the similar Diesel engine , developed a few years later.
69-458: Early internal combustion engines were quite successful running on gaseous and light petroleum fuels. However, due to the dangerous nature of petroleum and light petroleum fuel, legal restrictions were placed on their transportation and storage. Heavier petroleum fuels, such as kerosene , were quite prevalent, as they were used for lighting, but posed specific problems when used in internal combustion engines: Oil used for engine fuel must be turned to
138-481: A hydrated crystal is left in air, dehydration may occur slowly. This makes the color of the crystal become dull. Kerosene can keep air away from the crystal. Pythagoras Mechanical Workshop Museum Pythagoras Mechanical Workshop Museum ( Swedish : Pythagoras industrimuseum ) is located in the premises of the earlier engine factory Pythagoras at the town of Norrtälje in the province of Uppland in Sweden. At
207-471: A United States patent for the same invention. These patents were subsequently upheld in both countries in a series of lawsuits, and other producers were obliged to pay him royalties. In 1851, Samuel Martin Kier began selling lamp oil to local miners, under the name "Carbon Oil". He distilled this from crude oil by a process of his own invention. He also invented a new lamp to burn his product. He has been dubbed
276-612: A great deal of public excitement and investment drilling in new wells, not only in Pennsylvania, but also in Canada, where petroleum had been discovered at Oil Springs, Ontario in 1858, and southern Poland, where Ignacy Łukasiewicz had been distilling lamp oil from petroleum seeps since 1852. The increased supply of petroleum allowed oil refiners to entirely side-step the oil-from-coal patents of both Young and Gesner, and produce illuminating oil from petroleum without paying royalties to anyone. As
345-504: A heat source during power failures. Kerosene is widely used in Japan and Chile as a home heating fuel for portable and installed kerosene heaters. In Chile and Japan, kerosene can be readily bought at any filling station or be delivered to homes in some cases. In the United Kingdom and Ireland, kerosene is often used as a heating fuel in areas not connected to a gas pipeline network. It
414-490: A kerosene-based fuel, is used by the United States military as a replacement in diesel fueled vehicles and for powering aircraft. JP-8 is also used by the U.S. military and its NATO allies as a fuel for heaters, stoves, tanks, and as a replacement for diesel fuel in the engines of nearly all tactical ground vehicles and electrical generators. Aliphatic kerosene is a type of kerosene which has a low aromatic hydrocarbon content,

Other engineering companies had been offered the option of manufacturing the engine, but they saw it as a threat to their business, and so declined the offer. In 1892, T. H. Barton at Hornsbys enhanced the engine by replacing the vaporiser with
552-434: A local petroleum seep . Many people knew of his work, but paid little attention to it. On the night of 31 July 1853, doctors at the local hospital needed to perform an emergency operation, virtually impossible by candlelight. They therefore sent a messenger for Łukasiewicz and his new lamps. The lamp burned so brightly and cleanly that the hospital officials ordered several lamps plus a large supply of fuel. Łukasiewicz realized
621-536: A major political and environmental consequence. The Indian government subsidizes the fuel to keep the price very low, to around 15 U.S. cents per liter as of February 2007, as lower prices discourage dismantling of forests for cooking fuel. In Nigeria an attempt by the government to remove a fuel subsidy that includes kerosene met with strong opposition. Kerosene is used as a fuel in portable stoves , especially in Primus stoves invented in 1892. Portable kerosene stoves earn
690-459: A mechanically operated intake valve. Simultaneously, oil is injected into the vapouriser. The vapour of the oil is almost entirely confined to the vapouriser chamber. This cloud of hot oil vapour is too rich to support combustion. On the compression stroke (2) of the piston, the fresh air is forced through the narrow neck and into the vapouriser. Just as compression is completed, the mixture is just right to support combustion and ignition occurs to push
759-454: A much better light than a simple wick-type lamp does. Recently, a multipurpose lantern that doubles as a cook stove has been introduced in India in areas with no electricity. In countries such as Nigeria, kerosene is the main fuel used for cooking, especially by the poor, and kerosene stoves have replaced traditional wood-based cooking appliances. As such, increase in the price of kerosene can have

He was blocked from using it by the New Brunswick coal conglomerate because they had coal extraction rights for the province, and he lost a court case when their experts claimed albertite was a form of coal. In 1854, Gesner moved to Newtown Creek , Long Island , New York . There, he secured backing from a group of businessmen. They formed the North American Gas Light Company, to which he assigned his patents. Despite clear priority of discovery, Gesner did not obtain his first kerosene patent until 1854, two years after James Young 's United States patent. Gesner's method of purifying

This Hornsby-Akroyd oil engine design was hugely successful: during the period from 1891 through 1905, a total of 32,417 engines were produced. They would provide electricity for lighting the Taj Mahal , the Rock of Gibraltar , the Statue of Liberty (chosen after Hornsby won
966-418: A number of useful liquids from it, one of which he named paraffine oil because at low temperatures, it congealed into a substance that resembled paraffin wax. Young took out a patent on his process and the resulting products in 1850, and built the first truly commercial oil-works in the world at Bathgate in 1851, using oil extracted from locally mined torbanite, shale, and bituminous coal. In 1852, he took out
1035-440: A polluting fuel and recommends that "governments and practitioners immediately stop promoting its household use". Kerosene smoke contains high levels of harmful particulate matter , and household use of kerosene is associated with higher risks of cancer , respiratory infections, asthma , tuberculosis , cataracts , and adverse pregnancy outcomes. Kerosene is a low- viscosity , clear liquid formed from hydrocarbons obtained from
1104-498: A public demonstration in Charlottetown , Prince Edward Island of a new process he had discovered. He heated coal in a retort , and distilled from it a clear, thin fluid that he showed made an excellent lamp fuel. He coined the name "kerosene" for his fuel, a contraction of keroselaion , meaning wax-oil . The cost of extracting kerosene from coal was high. Gesner recalled from his extensive knowledge of New Brunswick 's geology
1173-438: A reputation of reliable and durable stove in everyday use, and perform especially well under adverse conditions. In outdoor activities and mountaineering, a decisive advantage of pressurized kerosene stoves over gas cartridge stoves is their particularly high thermal output and their ability to operate at very low temperature in winter or at high altitude. Wick stoves like Perfection's or wickless like Boss continue to be used by
1242-436: A result, the illuminating oil industry in the United States completely switched over to petroleum in the 1860s. The petroleum-based illuminating oil was widely sold as Kerosene, and the trade name soon lost its proprietary status, and became the lower-case generic product "kerosene". Because Gesner's original Kerosene had been also known as "coal oil", generic kerosene from petroleum was commonly called "coal oil" in some parts of
1311-539: A vapour state and remain in that state during compression. Furthermore, the combustion of the fuel must be powerful, regular, and complete, to avoid deposits that will clog the valves and working parts of the engine. The earliest mention of an oil engine was by Robert Street, in his English patent no. 1983 of 1794, and according to Horst O. Hardenberg there is evidence that he built a working version. Other oil engines were subsequently built by Etienne Lenoir , Siegfried Marcus , Julius Hock of Vienna and George Brayton in
1380-530: Is a custom-blended fuel used by the New York City Transit Authority to power its bus fleet. The transit agency started using this fuel in 2004, prior to the widespread adoption of ultra-low-sulfur diesel , which has since become the standard. In 2008, the suppliers of the custom fuel failed to tender for a renewal of the transit agency's contract, leading to a negotiated contract at a significantly increased cost. JP-8 (for "Jet Propellant 8"),

#17330861794961518-518: Is liquid around room temperature : 25 °C (77 °F). The flash point of kerosene is between 37 °C (99 °F) and 65 °C (149 °F), and its autoignition temperature is 220 °C (428 °F). The freezing point of kerosene depends on grade, with commercial aviation fuel standardized at −47 °C (−53 °F). Grade 1-K kerosene freezes around −40 °C (−40 °F, 233 K). The process of distilling crude oil/petroleum into kerosene, as well as other hydrocarbon compounds,
1587-424: Is produced by fractional distillation of crude oil in an oil refinery . It condenses at a temperature intermediate between diesel fuel , which is less volatile, and naphtha and gasoline , which are more volatile. Kerosene made up 8.5 percent by volume of petroleum refinery output in 2021 in the United States, of which nearly all was kerosene-type jet fuel (8.4 percent). The fuel, also known as heating oil in
1656-416: Is similar to that of diesel fuel ; its lower heating value is 43.1 MJ / kg (around 18,500 Btu / lb ), and its higher heating value is 46.2 MJ/kg (19,900 Btu/lb). The ASTM recognizes two grades of kerosene: 1-K (less than 0.04% sulfur by weight) and 2-K (0.3% sulfur by weight). Grade 1-K kerosene burns cleaner with fewer deposits, fewer toxins, and less frequent maintenance than 2-K, and
1725-557: Is sometimes used as fuel for small outboard motors or even motorcycles . World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023. The term "kerosene" is common in much of Argentina , Australia , Canada , India , New Zealand , Nigeria , and the United States , while the term paraffin (or a closely related variant) is used in Chile , East Africa , South Africa , Norway , and
1794-412: Is the preferred grade for indoor heaters and stoves. In the United Kingdom, two grades of heating oil are defined. BS 2869 Class C1 is the lightest grade used for lanterns, camping stoves, and wick heaters, and mixed with petrol in some vintage combustion engines as a substitute for tractor vaporizing oil . BS 2869 Class C2 is a heavier distillate, which is used as domestic heating oil. Premium kerosene
1863-420: Is used less for cooking, with LPG being preferred because it is easier to light. Kerosene is often the fuel of choice for range cookers such as Rayburn . Additives such as RangeKlene can be put into kerosene to ensure that it burns cleaner and produces less soot when used in range cookers. The Amish , who generally abstain from the use of electricity, rely on kerosene for lighting at night. More ubiquitous in
1932-498: Is usually sold in 5- or 20-litre containers from hardware, camping and garden stores, and is often dyed purple. Standard kerosene is usually dispensed in bulk by a tanker and is undyed. National and international standards define the properties of several grades of kerosene used for jet fuel . Flash point and freezing point properties are particularly interesting for operation and safety; the standards also define additives for control of static electricity and other purposes. Kerosene
2001-821: The Grandfather of the American Oil Industry by historians. Kier's salt wells began to be fouled with petroleum in the 1840s. At first, Kier simply dumped the oil into the nearby Pennsylvania Main Line Canal as useless waste, but later he began experimenting with several distillates of the crude oil, along with a chemist from eastern Pennsylvania. Ignacy Łukasiewicz , a Polish pharmacist residing in Lviv , and his partner Jan Zeh [ pl ] had been experimenting with different distillation techniques, trying to improve on Gesner's kerosene process, but using oil from

2208-873: The fractional distillation of petroleum between 150 and 275 °C (300 and 525 °F), resulting in a mixture with a density of 0.78–0.81 g/cm . It is miscible with petroleum solvents but immiscible with water. It is composed of hydrocarbon molecules that typically contain between 6-20 carbon atoms per molecule , predominantly containing 9 to 16 carbon atoms. Regardless of crude oil source or processing history, kerosene's major components are branched- and straight-chain alkanes (hydrocarbon chains) and naphthenes (cycloalkanes), which normally account for at least 70% of volume. Aromatic hydrocarbons such as alkylbenzenes (single ring) and alkylnaphthalenes (double ring), do not normally exceed 25% by volume of kerosene streams. Olefins are usually not present at more than 5% by volume. The heat of combustion of kerosene

In the early to mid-20th century, kerosene or tractor vaporizing oil was used as a cheap fuel for tractors and hit 'n miss engines . A petrol-paraffin engine would start on gasoline, then switch over to kerosene once the engine warmed up. On some engines a heat valve on the manifold would route the exhaust gasses around
2415-520: The Chrysler Horizon that integrated many Saab components) were made. One reason to manufacture kerosene-fueled cars was that in Finland kerosene was less heavily taxed than gasoline. Kerosene is used to fuel smaller-horsepower outboard motors built by Yamaha, Suzuki, and Tohatsu. Primarily used on small fishing craft, these are dual-fuel engines that start on gasoline and then transition to kerosene once
2484-491: The Downer Company (to which Gesner had granted the right) were allowed to call their lamp oil "Kerosene" in the United States. In 1848, Scottish chemist James Young experimented with oil discovered seeping in a coal mine as a source of lubricating oil and illuminating fuel. When the seep became exhausted, he experimented with the dry distillation of coal, especially the resinous "boghead coal" ( torbanite ). He extracted

Although it replaced whale oil , the 1873 edition of Elements of Chemistry said, "The vapor of this substance [kerosene] mixed with air is as explosive as gunpowder." This statement may have been due to the common practice of adulterating kerosene with cheaper but more volatile hydrocarbon mixtures, such as naphtha . Kerosene

To prevent confusion between kerosene and the much more flammable and volatile gasoline (petrol) , some jurisdictions regulate markings or colourings for containers used to store or dispense kerosene. For example, in the United States, Pennsylvania requires that portable containers used at retail service stations for kerosene be colored blue, as opposed to red (for gasoline ) or yellow (for diesel ). The World Health Organization considers kerosene to be

In the United Kingdom, manufacturing oil from coal (or oil shale) continued into the early 20th century, although increasingly overshadowed by petroleum oils. As kerosene production increased, whaling declined. The American whaling fleet , which had been steadily growing for 50 years, reached its all-time peak of 199 ships in 1858. By 1860, just two years later,

The Civil War cut into American whaling temporarily, but only 105 whaling ships returned to sea in 1866, the first full year of peace, and that number dwindled until only 39 American ships set out to hunt whales in 1876. Kerosene, made first from coal and oil shale, then from petroleum, had largely taken over whaling's lucrative market in lamp oil. Electric lighting started displacing kerosene as an illuminant in
3312-561: The heat of compression: An oil engine will have a decent compression ratio between 3:1 and 5:1, where a typical diesel engine will have a much harder achieved compression ratio ranging between 15:1 and 20:1, making it a lot more efficient. Also the fuel is injected easily during the early intake stroke and not at the peak of compression with a high-pressure Diesel injection pump . Akroyd-Stuart's engines were built from 26 June 1891 by Richard Hornsby & Sons in Grantham ,
3381-479: The heavier hydrocarbons that previously went into kerosene were incorporated into diesel fuel. Kerosene kept some market share by being increasingly used in stoves and portable heaters. A pilot project by ETH Zurich used solar power to produce kerosene from carbon dioxide and water in July 2022. The product can be used in existing aviation applications, and "can also be blended with fossil-derived kerosene." Kerosene

In Europe following the Second World War, automobiles were similarly modified to run on kerosene rather than gasoline, which they would have to import and pay heavy taxes on. Besides additional piping and the switch between fuels, the head gasket was replaced by a much thicker one to diminish
3519-482: The late 19th and early 20th centuries, kerosene space heaters were often built into kitchen ranges, and kept many farm and fishing families warm and dry through the winter. At one time, citrus growers used a smudge pot fueled by kerosene to create a pall of thick smoke over a grove in an effort to prevent freezing temperatures from damaging crops. " Salamanders " are kerosene space heaters used on construction sites to dry out building materials and to warm workers. Before

However, kerosene remained the predominant commercial end-use for petroleum refined in the United States until 1909, when it was exceeded by motor fuels. The rise of the gasoline-powered automobile in the early 20th century created a demand for the lighter hydrocarbon fractions, and refiners invented methods to increase their output of gasoline, while decreasing their output of kerosene. In addition, some of

It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft ( jet fuel ), as well as some rocket engines in a highly refined form called RP-1 . It is also commonly used as a cooking and lighting fuel, and for fire toys such as poi . In parts of Asia, kerosene
4347-664: Was repeated until most of the volatile hydrocarbon fractions had been removed and the final product was perfectly clear and safe to burn. Kerosene was also produced during the same period from oil shale and bitumen by heating the rock to extract the oil, which was then distilled. During the Chinese Ming Dynasty , the Chinese made use of kerosene through extracting and purifying petroleum and then converted it into lamp fuel. The Chinese made use of petroleum for lighting lamps and heating homes as early as 1500 BC. Although "coal oil"
4416-417: Was set up as the ignited gases flashed through the neck into the cylinder, where combustion was completed. As the engine's load increased, so did the temperature of the bulb, causing the ignition period to advance; to counteract pre-ignition, water was dripped into the air intake. The Stuart engine is of four cycle design. During the intake stroke (1), fresh air is inducted into the cylinder through
4485-404: Was simple, reliable and economical. It had a comparatively low compression ratio , so that the temperature of the air compressed in the combustion chamber at the end of the compression stroke was not high enough to initiate combustion. Combustion instead took place in a separated combustion chamber, the "vapouriser" (also called the "hot bulb") mounted on the cylinder head, into which fuel
4554-432: Was sprayed. It was connected to the cylinder by a narrow passage and was heated either by the cylinder's coolant or by exhaust gases while running; an external flame such as a blowtorch was used for starting. Self-ignition occurred from contact between the fuel-air mixture and the hot walls of the vapouriser. By contracting the bulb to a very narrow neck where it attached to the cylinder, a high degree of turbulence
4623-526: Was the first internal combustion engine to use a pressurised fuel injection system and also the first using a separate vapourising combustion chamber. It is the forerunner of all hot-bulb engines , which are considered kind of predecessors of the similar Diesel engine , developed a few years later. However, the Hornsby-Akroyd oil engine and other hot-bulb engines are distinctly different from Rudolf Diesel 's design, where ignition occurs alone through
