Diesel engines are typically well suited to turbocharging due to two factors: A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture.
Prior to Volkswagen Group's first TDI engine, the first turbocharged diesel engine used in a passenger car was an indirect injection five-cylinder engine fitted to the 1978 Mercedes-Benz 300SD (W116) 300 SD sedan. [13] The first turbodiesel engine with direct injection was the 1986 Fiat Croma 2.0 TD i.d. liftback sedan. [14]
1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).

A medium-sized six-cylinder marine diesel-engine, with turbocharger and exhaust in the foreground. Turbochargers have been used in the following applications: Petrol-powered car engines; Diesel-powered car and van engines; Motorcycle engines (quite rarely) Diesel-powered truck engines, beginning with a Saurer truck in 1938 [54] Bus and coach ...

The 4N1 engine family is the world's first to feature a variable valve timing (intake side) system applied to passenger car diesel engines. [ 10 ] All engines developed within this family have aluminium cylinder block , double overhead camshaft layouts, 4 valves per cylinder , a common rail injection system with a variable-geometry turbocharger .
