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.
Since diesel engines use much higher compression ratios (the heat of compression is used to ignite the slow-burning diesel fuel), that higher ratio more than compensates for air pumping losses within the engine. Modern turbo-diesel engines use electronically controlled common-rail fuel injection to increase efficiency.
Petrol can burn faster than diesel fuel, allowing higher maximum engine speeds and thus greater maximum power for sporting engines. Diesel fuel, on the other hand, has a higher energy density, and in combination with higher combustion pressures can deliver very strong torque and high thermodynamic efficiency for more "normal" road vehicles.
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).
GM claims that the 1.0-liter turbo is 25 percent (3 dBA) quieter than the Ford Fiesta's 1.0-liter turbo, and the 1.4-liter is up to 50 percent (6 dBA) quieter than the VW/Audi 1.4-liter turbo. Other silencing measures include a bed-plate cylinder block that increases stiffness and a stiffened aluminum front cam cover.
Fuel consumption monitor from a 2006 Honda Airwave. The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally ...
1978-1980 Mercedes-Benz OM617 indirect injection turbodiesel. 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]
A Diesel engine is a compression ignition engine and does not have a spark plug. To operate a diesel engine with an alternate combustible fuel source such as natural gas, a Dual-Fuel system used with natural gas as the main fuel while diesel fuel is used for the ignition of the gas/air mixture inside the cylinder. In other words, a portion of ...
