Most internal combustion engines now require a fuel pump. Diesel engines use an all-mechanical precision pump system that delivers a timed injection direct into the combustion chamber, hence requiring a high delivery pressure to overcome the pressure of the combustion chamber.
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
Consumption map of a 1.5-litre three-cylinder diesel engine. A consumption map or efficiency map [1] is a chart that displays the brake-specific fuel consumption of an internal combustion engine at a given rotational speed and mean effective pressure, in grams per kilowatt-hour (g/kWh).
Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
Such diagrams are available in the speciality literature. [1] [2] [3] The same information can be depicted in a normal orthogonal diagram, showing only two substances, implicitly using the feature that the sum of all three components is 100 percent. The diagrams below only concerns one fuel; the diagrams can be generalized to mixtures of fuels.
Multifuel automobiles, from several manufacturers, popularly known as "flex" autos, that run on any blend of ethanol and gasoline. Multifuel, sometimes spelled multi-fuel, is any type of engine, boiler, or heater or other fuel-burning device which is designed to burn multiple types of fuels in its operation.
In 2007 BMW sold its 50% stake to DaimlerChrysler and cancelled its contract for the Tritec engine. [1] BMW entered into a new joint venture with PSA Peugeot Citroen to develop the Prince engine which is used in the second generation Mini cars. [2] The factory had a capacity of 400,000 engines a year, [3] and in 2006 production was around ...
The aluminum construction and lightweight parts and materials in the manifolds helped reduce the weight of the engine by 20 percent compared with its iron-block 3G83 predecessor, while gains were also seen in torque, fuel economy and emissions. [1] Bore pitch is 80 mm.
