If the engine does not stop for 24 hours, change the gasoline generator oil once a month and replace the oil filter element and air filter element at the same time . Check engine oil regularly to see if it is lost and replenish it in time. If the working environment is harsh and dusty, clean the air filter frequently. Once every four months is enough. If it lasts a long time, it should be treated appropriately. If the viscosity decreases or the color turns black, it is time to change the oil.
What's wrong with a gasoline engine that can't be fired but can be fired by opening the fire valve?
< p>1. Poor ignition timing has a big impact. on the car. Gasoline in the engine Combustion must be ignited by sparks coming from the spark plug. For the engine to start smoothly and burn well, the spark from the spark plug must be sufficientamly strong, but more importantly, the moment when. the spark must be appropriate and correct. If it is too early, too late will affect engine power. The moment the spark comes out of the spark plug is called the ignition moment. It is usually expressed in terms of the angle of rotation of the crankshaft before the piston reaches top dead center, for example 10° before top dead center, rather than in units of time.2. Adjusting the ignition timing
1. Adjust the distributor power-off contact gap
The size of the contact gap not only affects the strength of the spark. , but also affects whether the contact opens and closes sooner or later. If you adjust the contact gap after adjusting the ignition timing, even a small change will occur. This will destroy the adjusted ignition timing, so the contact gap must be adjusted before adjusting the ignition timing.e, and the gap should be adjusted to the range of 0.35-0.40mm.
2. Find the top dead center position of the first cylinder compression stroke and loosen the first cylinder spark plug.
Slowly rotate the crankshaft. When you hear the deflating sound, it means that the first cylinder is on the compression stroke. Open the inspection hole cover on the flywheel housing, then slowly crank the crankshaft to align the timing mark.
3. If you have an octane selector, set it to the "0" scale position.
4. Determine the position where the circuit breaker contacts have just opened
Loosen the fixing screws of the distributor shell, and first rotate the shell in the direction of the distributor axis to make on both sides The contacts are in the closed position. Then turn on the ignition switch, and while rotating the distributor shell daIn the opposite direction to the distributor shaft, place the high voltage wire of the ignition coil facing the ground (approximately 2 to 3 mm) until you find sparks. Finally, tighten the distributor housing mounting screws.
5. Connect the high voltage wire according to the ignition sequence:
Reinstall the burner head and insert the high voltage wire from the first cylinder into the wiring hole aligned with the distributor cover and the conductive sheet of the burner head. Connect the high voltage wires of each cylinder in the order 1, 5, 3, 6, 2 and 4 clockwise.
6. Start-up Inspection:
Start the engine and allow it to run at normal temperature, then accelerate sharply if the engine makes a brief, light knock at this time. disappears immediately, the ignition time is appropriate. If there is no knocking noise, i.e. ignition time is delayed, loosen the housing retaining screwr of the distributor and rotate the distributor housing slightly in the direction opposite to the rotation of the distributor shaft. If the knocking noise is severe, i.e. if the ignition time is early, the distributor housing must be turned in the opposite direction as mentioned above until it fits.
1. The hand rope is broken. If the hand rope is broken, you can replace it directly, which generally costs one or two yuan each.
2. The generator hand-operated plate buckle broke, so the hand-operated plate was replaced directly.
3. The hand-pulled plate is inelastic. The above is the reason why the gasoline engine cannot be fired but can be fired by opening the fire valve.
