671-760: A hybrid engine. The engine uses a mixture of compressed air and gasoline injected into the cylinders. A key aspect of the hybrid engine is the "active chamber", which is a compartment heating air via fuel doubling the energy output. Tata Motors of India assessed the design phase towards full production for the Indian market and moved into "completing detailed development of the compressed air engine into specific vehicle and stationary applications". Petro-hydraulic configurations have been common in trains and heavy vehicles for decades. The auto industry recently focused on this hybrid configuration as it now shows promise for introduction into smaller vehicles. In petro-hydraulic hybrids,

732-448: A hybrid), unless it can accept power from outside. With large vehicles, conversion losses decrease and the advantages in distributing power through wires or pipes rather than mechanical elements become more prominent, especially when powering multiple drives—e.g. driven wheels or propellers. Until recently most heavy vehicles had little secondary energy storage, e.g. batteries/ hydraulic accumulators —excepting non-nuclear submarines , one of

793-484: A partnership can be arranged. Another form of a hybrid vehicle are the human-powered electric vehicles. These include such vehicles as the Sinclair C5 , Twike , electric bicycles , electric skateboards , and Electric motorcycles and scooters In a parallel hybrid vehicle, an electric motor and an internal combustion engine are coupled such that they can power the vehicle either individually or together. Most commonly

854-601: A petro-hydraulic powertrain for a typical American sedan car. The test car achieved over 80 mpg on combined EPA city/highway driving cycles. Acceleration was 0-60 mph in 8 seconds, using a 1.9-liter diesel engine. No lightweight materials were used. The EPA estimated that produced in high volumes the hydraulic components would add only $ 700 to the cost. Under EPA testing, a hydraulic hybrid Ford Expedition returned 32 mpg (7.4 L/100 km) City, and 22 mpg (11 L/100 km) highway. UPS currently has two trucks in service using this technology. Since 1985,

915-408: A power-split hybrid electric drive train, there are two motors: a traction electric motor and an internal combustion engine. The power from these two motors can be shared to drive the wheels via a power split device, which is a simple planetary gear set. The ratio can be from 100% for the combustion engine to 100% for the traction electric motor, or anything in between. The combustion engine can act as

976-399: A test bed to prove viability. The BMW 530i gave double the mpg in city driving compared to the standard car. This test was using the standard 3,000 cc engine, with a smaller engine the figures would have been more impressive. The design of petro-hydraulic hybrids using well sized accumulators allows downsizing an engine to average power usage, not peak power usage. Peak power is provided by

1037-480: A typical American sedan car. The test car achieved over 80 mpg on combined EPA city/highway driving cycles. Acceleration was 0-60 mph in 8 seconds, using a 1.9 L diesel engine. No lightweight materials were used. The EPA estimated that produced in high volumes the hydraulic components would add only $ 700 to the base cost of the vehicle. The petro-hydraulic hybrid system has a faster and more efficient charge/discharge cycling than petro-electric hybrids and

The energy is stored in the fuel of the internal combustion engine and an electric battery set . There are many types of petroleum-electric hybrid drivetrains , from Full hybrid to Mild hybrid , which offer varying advantages and disadvantages. William H. Patton filed a patent application for

1159-424: A vehicle establishes contact with an electrified rail, plate, or overhead wires on the highway via an attached conducting wheel or other similar mechanisms (see conduit current collection ). The vehicle's batteries are recharged by this process—on the highway—and can then be used normally on other roads until the battery is discharged. For example, some of the battery-electric locomotives used for maintenance trains on

1220-633: Is a category of multiple unit train built at Bombardier Transportation's plant in Crespin for the French rail operator SNCF . The train comes in three variants, electric, diesel or dual-mode. This train was first operated in 2004. It was created at the request of the regional railways of France, and has been very successful, with SNCF acquiring over 700 units. The AGC is designed to be modular, and regions can choose to create trains of 2 to 4 cars, in theory. So far, all trains built have had 3 or 4 cars. As well,

1342-567: Is also cheaper to build. The accumulator vessel size dictates total energy storage capacity and may require more space than an electric battery set. Any vehicle space consumed by a larger size of accumulator vessel may be offset by the need for a smaller sized charging engine, in HP and physical size. Research is underway in large corporations and small companies. The focus has now switched to smaller vehicles. The system components were expensive which precluded installation in smaller trucks and cars. A drawback

1403-706: Is charged when in low energy demanding vehicle operation. The charging engine runs at optimum speed and load for efficiency and longevity. Under tests undertaken by the US Environmental Protection Agency (EPA), a hydraulic hybrid Ford Expedition returned 32 miles per US gallon (7.4 L/100 km; 38 mpg ‑imp ) City, and 22 miles per US gallon (11 L/100 km; 26 mpg ‑imp ) highway. UPS currently has two trucks in service using this technology. Although petro-hydraulic hybrid technology has been known for decades and used in trains as well as very large construction vehicles,

1464-429: Is more efficient at producing torque, or turning power, while the combustion engine is better for maintaining high speed. Improved efficiency, lower emissions, and reduced running costs relative to non-hybrid vehicles are three primary benefits of hybridization. Mopeds , electric bicycles , and even electric kick scooters are a simple form of a hybrid, powered by an internal combustion engine or electric motor and

1525-539: Is to convert dual-mode (catenary and diesel-powered) high capacity self-propelled trains to dual-mode battery-powered AGCs. This project offers a proof of concept and a way forward to eliminating diesel trains by 2035, a target set by the French government and SNCF. SNCF announced on 18 March 2021 that 40% of the TER (French commuter rail) fleet will be renovated in the next 10 years, included AGC Class (699 trains) and TER 2N NG Class (232 trains). The most important contract

1586-416: Is to create a blank paper design new car, to maximize the packaging of petro-hydraulic hybrid components in the vehicle. All bulky hydraulic components are integrated into the chassis of the car. One design has claimed to return 130 mpg in tests by using a large hydraulic accumulator which is also the structural chassis of the car. The small hydraulic driving motors are incorporated within the wheel hubs driving

1647-538: Is wasted for idling: ≈60–85% of the time for these types of locomotives. It is unclear if regenerative braking is used; but in principle, it is easily utilized. Since these engines typically need extra weight for traction purposes anyway the battery pack's weight is a negligible penalty. The diesel generator and batteries are normally built on an existing "retired" "yard" locomotive's frame. The existing motors and running gear are all rebuilt and reused. Fuel savings of 40–60% and up to 80% pollution reductions are claimed over

1708-524: The B 82500 is only available in a four-unit version. In January 2021, Bombardier signed a new contract to retrofit and introduce a pre-series of five AGC battery-operated trains by 2023, in collaboration with SNCF Voyageurs and five French regions including Auvergne-Rhône-Alpes , Hauts-de-France , Nouvelle-Aquitaine , Occitanie and Provence-Alpes-Côte d'Azur . The 5 dual-mode (electric/diesel) AGC will be modified into battery-operated trains ( BEMU ) to help decarbonise French rail transport. The idea

1769-533: The French regions have acquired AGC Class trains (all variants together). The AGC Class fleet is the most important regional train in France as of 2010.

Small fleet sizes and installation costs are compensated by fuel savings, with advances such as higher capacity, lowered battery cost, etc. Toyota, Ford, GM and others are introducing hybrid pickups and SUVs. Kenworth Truck Company recently introduced

2623-407: The energy stored in the accumulator. A smaller more efficient constant speed engine reduces weight and liberates space for a larger accumulator. Current vehicle bodies are designed around the mechanicals of existing engine/transmission setups. It is restrictive and far from ideal to install petro-hydraulic mechanicals into existing bodies not designed for hydraulic setups. One research project's goal

2684-406: The engine is detached from the drivetrain, serving solely to charge the energy accumulator. The transmission is seamless. Regenerative braking can be used to recover some of the supplied drive energy back into the accumulator. A French company, MDI , has designed and has running models of a petro-air hybrid engine car. The system does not use air motors to drive the vehicle, being directly driven by

2745-475: The high costs of the equipment precluded the systems from lighter trucks and cars. In the modern sense, an experiment proved the viability of small petro-hydraulic hybrid road vehicles in 1978. A group of students at Minneapolis, Minnesota's Hennepin Vocational Technical Center, converted a Volkswagen Beetle car to run as a petro-hydraulic hybrid using off-the-shelf components.

3050-428: The same engine to be hybrids, although to avoid confusion with hybrids as described above and to use correctly the terms, these are perhaps more correctly described as dual mode vehicles: Hydraulic hybrid and pneumatic hybrid vehicles use an engine or regenerative braking (or both) to charge a pressure accumulator to drive the wheels via hydraulic (liquid) or pneumatic (compressed gas) drive units. In most cases

3111-519: The technology for such electrical infrastructure is largely outdated and, outside some cities, not widely distributed (see Conduit current collection , trams , electric rail , trolleys , third rail ). Updating the required electrical and infrastructure costs could perhaps be funded by toll revenue or by dedicated transportation taxes. In addition to vehicles that use two or more different devices for propulsion , some also consider vehicles that use distinct energy sources or input types (" fuels ") using

The modularity of these trains permits each railroad (or region) to choose the number of units – currently 3 or 4 – that make up the train, as well as the interior layout of the cars (e.g. lounge car , first class, etc.). Trains can also be made up of mixed units, i.e. a train can be made up from both BGC and ZGC units. Basse-Normandie and Lorraine regions have also ordered sets that consist of both diesel and electric units (i.e. XGC and ZGC). A two-unit variant has never been ordered;
