2. Unit injector - Wikipedia

   en.wikipedia.org/wiki/Unit_injector

   Unit injector. A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component. The plunger pump used is usually driven by a shared camshaft. In a unit injector, the device is typically lubricated and cooled by the fuel itself.

3. Injection pump - Wikipedia

   en.wikipedia.org/wiki/Injection_pump

   Injection pump. 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. It rotates at half crankshaft speed in a conventional four-stroke diesel engine.

4. Unit pump - Wikipedia

   en.wikipedia.org/wiki/Unit_pump

   Unit pump. The Unit Pump system [1] is a modular high-pressure diesel injection system, which is closely related to the unit Injector system, and is designed for use in commercial vehicle diesel engines. [2] The systems use an individual injection pump mounted on the engine block for each cylinder so it is primarily designed for OHV or "cam in ...

5. Electronically controlled unit injector - Wikipedia

   en.wikipedia.org/wiki/Electronically_controlled...

   An electronically controlled unit injector (EUI) is a unit injector (UI) with electronic control. It performs the same function as a conventional unit injector in an internal combustion engine, such as in an on-road or off-road vehicle or a diesel-electric locomotive. The pressurized delivery of fuel is camshaft -driven, but the timing of the ...

6. Fuel injection - Wikipedia

   en.wikipedia.org/wiki/Fuel_injection

   Fuel injection. A cutaway model of a petrol direct-injected engine. Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines.

7. Diesel engine - Wikipedia

   en.wikipedia.org/wiki/Diesel_engine

   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).
