What's the matter with no oil on the Yili Cannon?

[DiLeonardo]

It may be that the oil pump is clogged or burned out. The function of the gasoline pump is to suck gasoline out of the fuel tank and press it into the float chamber of the carburetor through pipelines and gasoline filters. The following is a detailed introduction to the gasoline pump: 1. It is not affected by air pressure and component wear: The gasoline pump works by using the eccentric wheel on the engine camshaft to drive. The camshaft of the diesel engine is installed in the crankcase, while the camshaft of the gasoline engine is installed on the cylinder head. The eccentric wheel drives the rocker arm, which pulls the diaphragm downward, compressing the spring. At this time, the space above the diaphragm becomes larger, creating negative pressure, which sucks fuel from the inlet. Because the outlet valve is closed, the fuel is stored in the volume above the diaphragm. The oil pump rotor is in contact with gasoline and will not cause wear, only responsible for providing pressure. The regulation of oil pressure is handled by the oil pressure regulator and is unrelated to atmospheric pressure. 2. The control of the gasoline pump is managed by the ECU: The gasoline pump is mainly determined by the ignition switch and the ECU. As long as the engine is running, the oil pump will work. If the engine stops, the interrupted signal will cause the transistor VT not to conduct, the relay L1 not to work, and the oil pump not to work. Even if the engine is not started, as long as the key switch is turned to the on position, the VT control circuit will conduct, generally causing the oil pump to operate for 3-5 seconds before shutting down, setting the pressure in the pipeline in advance.
