How to solve the problem if the engine of a Gasoline Tricycle is abnormal

The direct injection engine injector of a Gasoline Tricycle is equivalent to a safety valve. When the injector injects fuel, the hydraulic oil pipe beats like a human pulse. When the engine is running at a constant speed, the hydraulic oil pipe will beat regularly. However, if the engine is abnormal, there may be problems with the equipment. We often encounter people who put the engine at idle speed and then touch the high-pressure oil pipe with their hands for comparison. What are they doing?

1. Speed: For the engine, the oil pump camshaft cannot be changed structurally. Each cylinder supplies oil in the order of firing, and the high-pressure oil pipes naturally beat in sequence, and there will be no difference in speed.
2. Frequency: When the engine is working, the crankshaft rotates twice, and each cylinder is injected with oil once. According to the idle speed of 900r, each cylinder is injected 7-8 times per second. There will be no difference let alone the frequency. Even if there is The difference, so far as human perception is concerned, is also impossible to detect.
3. Strength: The beating is caused by large pressure changes in the high-pressure oil pipe. Because of the different change values, the intensity of the beating is also different. The pressure of the oil outlet valve generally does not occur, so the high pressure value in the pipe The change becomes the only cause of the change in beating intensity, which is the so-called high-pressure pulsation abnormality.
Abnormal engine high-pressure pulsation in Gasoline Tricycle accessories can be dealt with using the above methods. At the same time, if the Gasoline Tricycle has technical problems, you can consult the manufacturer's technical personnel to avoid blind repairs that may cause equipment failure.
