2. Fuel pump - Wikipedia

   en.wikipedia.org/wiki/Fuel_pump

   A Fuel pump is a component used in many liquid-fuelled engines (such as petrol/gasoline or diesel engines) to transfer the fuel from the fuel tank to the device where it is mixed with the intake air (such as the carburetor or fuel injector). Carbureted engines often use low-pressure mechanical pumps that are mounted on the engine.

3. Power take-off - Wikipedia

   en.wikipedia.org/wiki/Power_take-off

   A PTO at the rear end of a farm tractor A PTO (in the box at the bottom) in the center of the three-point hitch of a tractor. A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.

4. 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. It rotates at half crankshaft speed in a ...

5. Electronically controlled unit injector - Wikipedia

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

   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 injector's internal operations are controlled by the engine control unit so as to achieve certain ...

6. Unit pump - Wikipedia

   en.wikipedia.org/wiki/Unit_pump

   Unit pumps on Mack's E7 diesel engine Unit pumps on Mercedes OM906LA engine. 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 ...

7. 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).
