He later moved to Georges Richard where he met Jacques Bizet, who had the funds to back a new automotive brand and

54-668: A Kestrel V12 to diesel operation using single sleeve valve technology: Captain George Eyston used the new engine in the Flying Spray , which, at 159 miles per hour (256 km/h), broke the world diesel speed record at Bonneville in May 1936. Also in the 1930s, Sir Henry Tizard , Chairman of the Aeronautical Research Committee , who was a proponent of a high-powered "sprint" engine for fighter aircraft and who had foreseen

81-471: A 3.8 litre twin-turbo V8, which became known as the McLaren M838T , for its supercars. At around the same time, the company working in collaboration with Israel Aerospace Industries , developed a semi-robotic tug, Taxibot , which clamped around the aircraft's nosewheel and was controlled remotely by the pilot; the product was intended to reduce aviation fuel consumption. The Ministry of Defence selected

108-449: A 4-stroke crosshead-type engine for the Mark V tank which produced 150 brake horsepower (110 kW) but emitted no visible smoke detectable by the enemy. After the war, the company developed a side-valve engine, which minimised the clearance between the piston and cylinder head thereby achieving all the advantages of overhead-valve engines without the cost. This new type of engine, known as

135-586: A new diesel speed record of 350.092 miles per hour (563.418 km/h) at Bonneville Salt Flats in Utah, in the JCB Dieselmax with the aid of a diesel engine designed with Ricardo combustion-chamber technology. The company went on, in around 2008, to develop an engine capable of switching between two-stroke and four-stroke cycles in collaboration with Denso , Jaguar Land Rover and the Centre for Automotive Engineering at

162-599: A proportion of exhaust gas with fresh oxygen. In the 1970s, Opel used Ricardo combustion-chamber technology for the Opel 2100D engine which was installed in the Opel Rekord Series D . General Motors used the same technology in the Chevrolet Suburban in the 1980s. In 1990, the company undertook the development of an automatic layshaft transmission as part of an integrated power-train control system. Then, in 1994,

189-610: Is listed on the London Stock Exchange . The company was founded by Sir Harry Ricardo as Engine Patents Limited in February 1915. Later in 1915, during the First World War , the company helped develop a 600 brake horsepower (450 kW) engine for a flying boat . In spring 1916, it helped with the design of a device to manoeuvre 25 tonnes (28 tons) battle tanks into position aboard railway wagons. Later in 1916, it designed

216-517: The University of Brighton : it was claimed that the engine could improve fuel economy by up to 25%. The company collaborated with Xtrac by assisting with some parts manufacture for the 1044 gearbox, supplied in 2010 to three Formula One teams: Lotus , Virgin and HRT . This gearbox was mated to the Cosworth CA2010 engine. In 2009, McLaren Automotive selected Ricardo to develop a new engine,

The United States Navy placed a contract with the company, in 1968, to develop a diesel power unit capable of running for extended periods at ocean depths of up to 600 feet (180 m); the concept was known as "recycle diesel" and involved blending

297-593: The First World War, the particularly light Le Zèbre cars turned out to be a “go-anywhere” vehicle and were selected for use as liaison vehicles by the French Army . From 1915, the Ministry of War placed an order for 40 cars per month, which allowed the company to retain the majority of its employees and avoid military requisition, unlike most other French car factories. In 1917 the two founders split up. Jules Salomon left

324-461: The Type A was further assured by Baudry de Saunier, the greatest French automotive journalist of the time, who repeatedly extolled the car’s virtues. In 1912 Le Zèbre announced their second model, the Type B. More imposing, it was a 1750cc four-cylinder, four-seater car, rated at 10CV and with a wheelbase of 260 cm (103 in). It sold for 6,000 F, which constituted another economic tour de force for

351-420: The ambition to leave a legacy to rival that of his father. The two friends decided not to give their names to the car, instead opting to call it "Le Zèbre" (The Zebra), which was originally a nickname given to a clerk of their former employer. In 1909 Salomon developed his first car, a 600cc single-cylinder Cyclecar with two-speed and reverse gearbox and shaft drive, which was designated the Type A. This design

378-471: The automotive world for his studies on combustion systems and the many associated patents he held, it had a 2-litre 10CV, four cylinder engine with aluminium pistons, hemispherical combustion chambers, and was priced from 24,000 F. The Le Zèbre- Ricardo partnership was warmly welcomed by the trade press, which hoped that the Suresnes company will be able to get out of its period of stagnation. From 1925 to 1930, it

405-467: The beginning of 1923, only Types A and D appeared in the catalogue, supplemented at the end of the year by the Type E, a sports version of the Type D. The pre-war Type C also reappeared, with sightly revised and improved bodywork. It was not until the end of 1924 that a much more serious project saw the light of day, in the form of the Type Z. Entirely designed by the English engineer Harry Ricardo , known in

432-597: The company acquired a major developer of four-wheel drive technology, FF Developments ; this business formed the basis of the company's driveline operations in the UK. In the early 21st century, the company undertook work to improve the BMW K1200 series motorcycle engines which were subsequently fitted to the BMW Motorrad K1300S, K1300GT and K1300R models. In August 2006, Wing Commander Andy Green successfully achieved

459-399: The company and met André Citroën , the then director general at Mors and was instrumental in the development of the first Citroen cars. Le Zèbre’s ownership structure was revised, with Jacques Bizet resigning his executive position, although retaining a commercial stake in the company. From 1918, the new Type D was marketed. It had a four-cylinder engine of 998cc and four-speed gearbox, and

486-563: The company developed the V-16 engine for the Alfa Romeo Tipo 162 , a car with highly streamlined bodywork. In 1941, the company developed a relief valve subsequently named "Barostat", which automatically reduced the pressure in the fuel lines as the aircraft gained altitude, thereby avoiding the risk of the engine overspeeding : the Gloster E.28/39 , designed by Frank Whittle , used this device. In

513-475: The company to create a rival company, Amilcar . Le Zèbre struggled to cope with the loss of these key personnel and their associated capital, as well a good deal of their commercial network which Lamy and Akar were able to lure away to their new project. With the Le Zèbre brand destabilized by the loss of key personnel, the original Type A reappeared, delivered with the Type C chassis and a slightly modified body. At

594-525: The need for such a powerplant with the threat of German air power looming, encouraged Ricardo to develop what eventually became the Rolls-Royce Crecy engine. In 1931, Harry Ricardo gave a lecture to the Royal Society of Arts , in which he invited his audience to "accompany me inside the cylinder of a diesel engine", passionately describing the process of diesel combustion, in great detail. In 1938,

621-463: The time. The Type B was closely followed by the Type C, also a four-cylinder three-speed, but this time of 785cc, which was available only as a two-seat torpedo body on its 200 cm (80 in) wheelbase. All three models were produced from the company’s new factory in Suresnes . Le Zèbre became well known for their unique blend of robustness, reliability and low running costs. On the outbreak of

648-470: The turbulent head, was patented in 1932. The company went on to design a 6-cylinder diesel engine producing 130 brake horsepower (97 kW) which was manufactured by AEC for use in London bus fleets. This type of engine, branded as The Comet , was taken up by Berliet and Citroën of France, MAN of Germany, and Fiat and Breda of Italy, among others. In the 1930s, the company undertook work to convert

675-405: Was priced very aggressively, selling for 3,000 Francs, or 1,000 F less than competitors. The wheelbase was 180 cm (71 in) and the car weighed 300kg. The Type A was well received by the public, and attracted investment from influential businessmen Emile Akar and Joseph Lamy, which enabled factory relocation and expansion. Joseph Lamy assumed the function of Commercial Director. The success of

702-476: Was rated at 8CV. It was available in 3-seat torpedo , 4-seat sedan or saloon versions, with wheelbases between 250 cm (98 in) and 290 cm (114 in). With prices between 10,200 F and 16,500 F remained very affordable. In April 1919 André Morel joined the company as Sales Manager for the whole of the Southern France. In 1921, Edmond Moyet (Chief Engineer), Morel , Akar and Lamy withdrew from

729-516: Was the only car marketed by Le Zèbre but in the end only 550 Type Z’s were built. Faced with this new failure and the economic slump , the company closed permanently in 1931. Another collaboration with Ricardo featured a radical single-cylinder, opposed-piston, two-stroke, diesel-engine and was shown at the 1931 Paris Salon, but came too late to save the company. Altogether, Le Zèbre produced 9,500 cars between 1909 and 1931, of which about 250 examples remain today. Jules Salomon From Misplaced Pages,
