There are three lubrication methods for automobile engines. The detailed information is as follows: 1. Splash lubrication: This method utilizes oil droplets splashed by rotating components such as the crankshaft and camshaft during engine operation, or oil sprayed from oil holes on the connecting rod big end to lubricate friction surfaces. 2. Periodic lubrication: This involves regular greasing for lubrication, primarily applied to components like generators, starters, and water pump bearings. 3. Pressure lubrication: An oil pump delivers lubricating oil under pressure to the friction surfaces of components, forming an oil film of sufficient thickness to withstand mechanical loads and ensure reliable lubrication.

What is the working principle of an air flow meter?

Air flow meter works by maintaining a constant voltage, while the intake air volume changes the resistance of the air flow meter, thereby altering the current, which is then transmitted to the vehicle's ECU. The air flow sensor, also known as the air flow meter, is one of the key sensors in an electronic fuel injection engine. It converts the intake air flow into an electrical signal and sends it to the ECU as one of the fundamental signals for determining fuel injection. It is a sensor that measures the air flow entering the engine. With the introduction of microcomputers for fuel injection control, several other types of air flow sensors have emerged, such as the vane-type air flow sensor and the Karman vortex air flow sensor.

What to Do When Car Paint is Scratched Down to the Primer?

If the car paint is scratched down to the primer, it is recommended to visit a paint repair center that offers quick scratch repair services. These centers use specialized touch-up paints that can prevent the scratch from expanding further. The touch-up paint dries quickly and blends naturally with the original car paint, ensuring no color difference and leaving no visible repair marks. Whether the scratch has reached the primer or not, it is advisable to repair any deep scratches to prevent rusting over time, which can further affect the car's appearance. If the metal shell is scratched and the primer is exposed, it won't rust, but if the metal is exposed, even slightly, immediate repair is necessary to prevent the damage from spreading. The car primer is the first layer of paint applied to the car body, and it primarily serves to protect the car body before the next painting process.
