The reasons why there is no high voltage spark in the EFI engine are: 1. Fuel system reasons: the low pressure oil line is blocked, the pipeline is loose and is leaking, there is air in the high pressure. -oil pipe under pressure, the technical condition of the fuel injector is not good and the injection timing angle is incorrect 2. Starting device reasons: power failure, poor ignition contact the electromagnetic switch, poor contact between the collector; of the starter and brush, clutch slippage of the starter transmission mechanism; 3. Insufficient cylinder compression pressure: damaged cylinder seal, air leak, valve closing failure. Significant air leakage, wear and leakage of the piston cylinder liner. 4. Insufficient air intake: The air filter element is clogged.
1. First check whether the engine oil andgasoline are newly added. Otherwise, they have been added for more than three months and the oil and gasoline need to be drained and replaced. Engine oil and gasoline are only valid for three months. Oil and gasoline used for more than three months have lost their viscosity and are useless.
2. Check if the engine oil and gasoline in the generator are filled. Otherwise, the generator will not turn on or start.
3. If the above conditions are met, check whether the spark plug ignites. Otherwise, remove the spark plug and put gasoline on it before reinstalling it to see if the generator fires. , it would be good if it started with the ignition.
Detailed information
Before each use of a gasoline generator, the following checks should be carried out to ensure safe and normal use of the generator: < p>1. If the generator is not used fora long time (more than a month), the starter battery will lose power due to self-discharge. Please use an external charger to charge the battery.
2. Check if there is enough gasoline in the fuel tank.
3. Check the oil switch and oil pipeline for oil leaks.
4. Check whether the battery starting voltage is higher than 12V and observe whether the battery appearance is damaged or leaking.
5. Observe the quality of the engine oil to determine if it needs to be replaced.
6. Check if the engine oil level is between the oil dipstick grids.
