Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber. Gasoline engines equipped with indirect injection systems, wherein a fuel injector delivers the fuel at some point before the intake valve , have mostly fallen out of favor to direct injection .
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 the 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).
The fuel system uses a Bosch mechanical distributor-type (Bosch VE type) injection pump which feeds indirect fuel injection into a remote whirl pre-combustion chamber. The cooling system is composed of a timing belt driven water pump, an 87 °C thermostat in the engine block itself.
The Ford EEC-III single-point fuel injection system, introduced in 1980, was another early digital fuel injection system. [ 56 ] [ 57 ] These and other electronic manifold injection systems (using either port injection or throttle-body injection ) became more widespread through the 1980s, and by the early 1990s they had replaced carburettors in ...
The PSA XUD is a diesel engine designed and built by PSA — Peugeot and Citroën.It is an Indirect injection (IDI) engine, that uses a version of the Ricardo Consulting Engineers Ricardo Comet V prechamber cylinder head design. [1]
The Mercedes-Benz OM604 is a 2.0 litres (1,997 cc) and 2.2 litres (2,155 cc) inline-four cylinder (R4/I4) double overhead camshaft (DOHC) diesel engine with indirect injection manufactured by Mercedes-Benz between 1993 and 1998. [1] It replaced the single overhead camshaft (SOHC) OM601 engine.
Injection pump for a 12-cylinder diesel engine An injection pump is the device that pumps fuel into the cylinders of a diesel engine . Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt ) that also drives the camshaft .
