2. Unit injector - Wikipedia

   en.wikipedia.org/wiki/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. Common rail - Wikipedia

   en.wikipedia.org/wiki/Common_rail

   Diesel fuel injector as installed in a MAN V8 Diesel engine. Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).

   en.wikipedia.org/.../Animated_Fuel_Injector

   An animated cut away diagram of a typical fuel injector. Fuel injectors are used to spray controlled amounts fuel into an internal combustion engine . A solenoid is activated when fuel is intended to be delivered to the engine causing the plunger to become pulled toward the solenoid by magnetic force.

5. Fuel injection - Wikipedia

   en.wikipedia.org/wiki/Fuel_injection

   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.

6. Injection pump - Wikipedia

   en.wikipedia.org/wiki/Injection_pump

   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 .

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).
