History of the diesel car developments (Mercedes-Benz, BMW, Peugeot/Citroën, Fiat, Alfa Romeo, Volkswagen Group) There were also small diesel engines produced in England by British Leyland and Perkins. For reasons of economy the petrol BMC "B" series engine was dieselised and produced in capacities of 1.5 and 1.8 litres. Perkins produced the 4.99, 4.107 and 4.108 engines all of which were extremely reliable. Later BL produced the five main bearing "O" series engine which was extremely strong. Petrol turbo variants could make 200HP and the engine was ideal for converting to a diesel. In fact, the 1988 Austin-Rover MDi unit (also known as the 'Perkins
Turbo-diesel Turbo-diesel Turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. Turbocharging is common in modern car and truck diesel engines to produce higher power outputs, lower emissions levels, and improved efficiency from a similar capacity of engine. Turbo-diesels in automobiles offer a higher refinement level than their naturally aspirated counterparts. The turbocharger was invented in the early 20th century by Alfred Büchi, a Swiss engineer and the head of diesel engine research at Gebruder Sulzer engine manufacturing company in Winterthur. Büchi specifically intended his device to be used on diesel engines. His
