Where is the location of the injection pump?
Where is the location of the injection pump?
In petrol engines, the fuel pump is usually located inside the fuel tank. In diesel engines, the fuel tank holds an auxiliary pump, while the injection pump, generating high pressure and controlling the order in which the injectors are opened, is located next to the engine.
How do I check my injector timing?
You can check the injection timing by measuring the injector pump’s stroke at TDC using a dial indicator.
How fuel timing is controlled in fuel pump?
Abstract. A fuel injection timing control system for a diesel engine has a fuel injection pump supplying fuel to the engine periodically according to the rotation of the engine crankshaft, and a device connected to the fuel injection pump to vary the fuel injection timing in terms of crank angle.
How the injection timing affect the engine knock?
The results show that as for Position A (ethanol injecting toward spark plug), with the delay of injection timing, knock tendency and its intensity increase initially and then decrease due to the comprehensive effect of ethanol evaporation and fuel stratification; on the contrary, for Position B (ethanol injecting …
What is fuel injection timing?
Start of injection (SOI) or injection timing is the time at which injection of fuel into the combustion chamber begins. It is usually expressed in crank angle degrees (CAD) relative to TDC of the compression stroke.
Why is checking injection timing is important?
Injection timing is an important engine parameter, which significantly affects the odorous emissions. If injection starts earlier, the initial air temperature and pressure are lower so the ignition delay would increase.
What is the importance of injection timing?
How injection timings affect an engine explain?
What controls the timing of an injector?
A fuel injection timing control system for a diesel engine has a fuel injection pump supplying fuel to the engine periodically according to the rotation of the engine crankshaft, and a device connected to the fuel injection pump to vary the fuel injection timing in terms of crank angle.
