What is the purpose of fuel injection timing?
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 optimum injection timing?
Optimum injection timing found to be 60° BTDC for stoichiometric condition (φ = 1.0) which gives the indicated efficiency of 39.33%, however, optimum injection timing was obtained 10° BTDC for lean condition (φ = 0.2).
What is diesel spill timing?
Injection timing, also called spill timing, is the moment when diesel fuel enters the cylinder during the combustion phase. When you adjust the timing, you can alter when the engine injects the fuel, therefore changing when combustion occurs.
How to check fuel pump injection timing?
Take out deflector on both sides of the fuel pump
How can I change the fuel injector?
How to Replace Fuel Injectors The metal rod over the fuel injectors is the fuel rail. Use the socket and ratchet to remove the bolts and brackets holding the fuel rail in place. Make sure the engine is cold enough to touch. Disconnect the battery. Remove plastic engine covers using appropriate socket. Use pliers to disconnect the electrical connector on each injector.
How is air and fuel mixed in an injector?
Mechanical Fuel Injector. While entering inside the cylinder, the fuel and air must be mixed very precisely, with the right amount of both. This is achieved by using the flap valve, which is located inside the air intake of the engine. It lets the fuel come in the correct flow to be mixed with the air in the right amount.
Do I need fuel injector flush?
If you have never had the fuel injectors service or you are having problems that need the injectors flushed then it should be done. If you are not having any problems then running good fuel and additives in the fuel tank to keep the injectors clean will keep them clean.
