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. Indirect injection - Wikipedia

   en.wikipedia.org/wiki/Indirect_injection

   Adding indirect injection keeps fuel spraying on the intake valves, reducing or eliminating the carbon accumulation on intake valves and in low load conditions, indirect injection allows for better fuel-air mixing. This system is mainly used in higher cost models due to the added expense and complexity. Port injection refers to the spraying of ...

4. Fuel injection - Wikipedia

   en.wikipedia.org/wiki/Fuel_injection

   Prior to 1979, the electronics in fuel injection systems used analogue electronics for the control system. The Bosch Motronic multi-point fuel injection system (also amongst the first systems where the ignition system is controlled by the same device as the fuel injection system) was the first mass-produced system to use digital electronics.

5. Manifold injection - Wikipedia

   en.wikipedia.org/wiki/Manifold_injection

   Mechanic fuel injection pump system "Kugelfischer" This system uses a three-dimensional cam. In early manifold injected engines with fully mechanical injection systems, a gear-, chain- or belt-driven injection pump with a mechanic "analogue" engine map was used. This allowed injecting fuel intermittently, and relatively precisely.

6. Bi-fuel vehicle - Wikipedia

   en.wikipedia.org/wiki/Bi-fuel_vehicle

   A Diesel engine is a compression ignition engine and does not have a spark plug. To operate a diesel engine with an alternate combustible fuel source such as natural gas, a Dual-Fuel system used with natural gas as the main fuel while diesel fuel is used for the ignition of the gas/air mixture inside the cylinder. In other words, a portion of ...

7. Jetronic - Wikipedia

   en.wikipedia.org/wiki/Jetronic

   Mechanical fuel injection, 'K' stands for German: "Kontinuierlich", meaning continuous.Commonly called 'Continuous Injection System (CIS) in the USA. K-Jetronic is different from pulsed injection systems in that the fuel flows continuously from all injectors, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi).
