Why can't the gasoline generator start?
1. First check if the engine oil and gasoline have been added recently. Otherwise, they have been added more than three months ago. oil and gasoline. Drain the gasoline and replace it again. Since engine oil and gasoline are only valid for three months, oil and gasoline used for more than three months have lost their viscosity and have no effect.
2. It is difficult for old gasoline generators to ignite. The reason is that the spark plugs have carbon deposits. They either have to clean them or replace them with new ones. too dirty, resulting in lack of air. To clean or replace. If the engine oil has melted, because if the machine is not used for a long time, the engine oil should be drained, and if the gasoline is qualified and it has evaporated, resulting in purity insufficient. Difficulty igniting.
3. Check whether the starting method is correct, such as whether the oil switch is on, whether the shock absorber is closed when the cold engine starts for the first time, whether the starting method is correct, and whether the starting method is correct. startup has been achieved. Rotational speed, etc., then troubleshoot in the order of first checking the oil circuit, then checking the circuit, then checking the cylinder compression. First, turn on the crankcase oil drain switch, quickly pull the engine and identify the faulty area by observing the oil flow. If no oil flows from the oil switch or little oil flows, it means that the mixture is not entering the cylinder or it is too thin. If there is a lot of oil leaking from the oil switch, the mixture is too rich. The reason may be that there is a problem with the oil supply system or the starting method is incorrect.
4. Remove the high voltage wire from the spark plug and test for fire: if there is no spark or the spark is very weak, it means there is a fault with the magneto or high voltage. thread ; If the spark is strong, it means there is a fault with the spark plug or the cylinder is leaking and the mixture is poorly compressed. Next, check or replace the spark plug. If it is confirmed that the spark plug is functioning normally, further check the compression condition of the cylinder. Poor mixture compression in the cylinder may be due to a leak in the cylinder or a leak in the crankcase. The location of the leak can be detected through external inspection. If the air leak is caused by excessive mounting clearance (such as mounting clearance between the piston and the cylinder wall or various parts of the piston ring, etc.) or damage to the parts, the machine must be dismantled and inspected. ForSome magneto and multi-cylinder gasoline engines using battery ignition systems, after setting the stage gap and angle, it is necessary to check and adjust the ignition timing and correct the ignition sequence ignition, because if the ignition sequence is disturbed, the machine will not be easy to start.
5. It's difficult to start a gasoline generator and new machines require a certain break-in period, so the longer the generator is used, the better it will be. , but broken down, so it is better to start the generator 1 to 2 times a month.
The following steps are recommended for inspection and maintenance:
1. Determine if the anti-theft system is locked
2. the starting system works (if the starter works);
3.1 The starting system is normal, check whether the ignition system is normal
3.2 The starting system is abnormal and running; lenFinally, check the battery voltage, if the starter is defective and if the motor has too much resistance; the starter does not work, check the circuit and the electromagnetic switch of the starter.
4.1 Ignition system is normal, check fuel systemIs this normal?
4.2 The ignition system is abnormal. Check the ignition system circuit, check whether the crankshaft position sensor and camshaft position sensor are normal, and check the power supply and grounding of the ECU.
