How to set the oil feed time of Purple Oil Isuzu:
1. Connect the high pressure oil pipe to the oil pump, turn the steering wheel and observe whether the oil supply line on the steering wheel is aligned with the line on the water tank. For fuel injection, increase the oil pump seal at the beginning of the fuel supply time and reduce the seal if it is late. The fuel injection effect is better when the two marking lines are optimally aligned. Fuel delivery time is 18-22 seconds before top dead center between degrees Celsius.
2. Oil supply time for single cylinder diesel engine. When the oil supply time is too early, the mixed gas will form in advance and ignite prematurely. the ascending piston. In the diesel engine, at the time of extinction, the back pressure is greater than the inertia compression forceupward movement of the piston, forcing the piston down, causing the crankshaft to reverse, so the fan or flywheel also reverses. When the fuel supply time is too late, the formation of the gas mixture and the combustion process are delayed until the piston descends quickly and the original high expansion force cannot be generated at the moment when the diesel engine stalls. , the rotational inertia of the crankshaft When the force becomes smaller, it immediately stops rotating, which is manifested by the phenomenon that the fan or flywheel immediately stops moving.
3. The fuel injection pump that has been operating for more than 500 hours or has been repaired will be adjusted to the optimal fuel feed advance angle.
