2. Fuel pump - Wikipedia

   en.wikipedia.org/wiki/Fuel_pump

   Since the electric pump does not require mechanical power from the engine, it is feasible to locate the pump anywhere between the engine and the fuel tank. The reasons that the fuel pump is typically located in the fuel tank are: By submerging the pump in fuel at the bottom of the tank, the pump is cooled by the surrounding fuel; Liquid fuel by ...

3. Electronically controlled unit injector - Wikipedia

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

   The fuel is forced into the cylinder through the spray tip. Pressure reduction phase Toward the end of the pump stroke, the spill valve is re-opened, allowing the fuel to recirculate again and ending the injection phase. Thus, although the mechanical plunger pump has a fixed stroke, electronic control can select any part of that stroke to ...

4. Manifold injection - Wikipedia

   en.wikipedia.org/wiki/Manifold_injection

   The fuel distributor does not have to create any injection pressure, because the fuel pump already provides pressure sufficient for injection (up to 500 kPa). Therefore, such systems are called "unpowered", and do not need to be driven by a chain or belt, unlike systems with mechanical injection pumps.

5. Electronic Diesel Control - Wikipedia

   en.wikipedia.org/wiki/Electronic_Diesel_Control

   The mechanical fly-weight governors of inline and distributor diesel fuel injection pumps used to control fuel delivery in diesel engines under a variety of engine loads and conditions could no longer deal with the ever-increasing demands for efficiency, emission control, power and fuel consumption. These demands are now primarily fulfilled by ...

6. Secondary air injection - Wikipedia

   en.wikipedia.org/wiki/Secondary_air_injection

   The mechanism by which exhaust emissions are controlled depends on the method of injection and the point at which air enters the exhaust system, and has varied during the course of the development of the technology. The first systems injected air very close to the engine, either in the cylinder head's exhaust ports or in the exhaust manifold.

7. Electrofuel - Wikipedia

   This information came after a lengthy test process in collaboration with Saudi Aramco. 24 engine families installed in Europe since 2014 were tested for exhaust emissions, startability, engine performance, reliability, durability, oil dilution, fuel tank, fuel lines and filters, as well as fuel performance in extreme cold and high temperatures.
