What is the function of the oil pump?

The function of the oil pump is to pressurize the oil from the oil pan and deliver it to the oil filter and various lubrication channels, thereby lubricating the main moving components of the engine and ensuring the oil is filtered. During engine operation, the oil pump continuously works to maintain the circulation of oil within the lubrication system. Under various engine operating conditions, the oil pump must ensure an adequate supply of lubricating oil. In automotive engines, gear-type and rotor-type oil pumps are commonly used. Both types operate on the same principle, transforming low-pressure oil into high-pressure oil through changes in volume, hence they are also referred to as positive displacement oil pumps.

What is the working principle of an ignition coil?

The working principle of an ignition coil is: to repeatedly store and release energy at different frequencies according to the engine speed. When the primary coil is connected to the power supply, a magnetic field is generated around it as the current increases, and the iron core stores the magnetic field energy. When the switch device disconnects the primary coil circuit, the magnetic field of the primary coil decays rapidly, and the secondary coil induces a high voltage. The replacement steps for the ignition coil are: 1. Open the ignition coil cover on the top of the engine; 2. Remove the ignition coil fixing screws; 3. Disconnect the ignition coil power plug; 4. Remove the ignition coil; 5. Install another ignition coil and tighten the screws; 6. After connecting the power plug, cover the top cover plate.

What is the working principle of engine mechanical supercharging?

The working principle of engine mechanical supercharging is: using the engine's own power to drive the turbine to start supercharging. The mechanical supercharger is connected to the engine crankshaft pulley via a belt, utilizing the engine's speed to drive the internal blades of the mechanical supercharger, thereby generating pressurized air that is sent into the engine's intake manifold, increasing the air intake within the engine and enhancing the engine's power. The classifications of mechanical supercharging include: 1. Centrifugal mechanical supercharger; 2. Roots-type mechanical supercharger; 3. Screw-type supercharger. The characteristics of mechanical supercharging are: 1. No need for cooling; 2. Maintenance-free; 3. Long lifespan; 4. Fast power output; 5. Improved driving performance.
