On the high performance and high power enhanced engine, due to the large heat load, oil cooler must be installed. The oil cooler is arranged in the lubricating oil circuit, and its working principle is the same as that of the radiator.
Engine oil coolers are divided into air cooled and water-cooled. The water-cooled oil cooler is widely used in cars due to its small size, convenient layout, and no excessive cooling of the oil and stable oil temperature.
If these surfaces are not lubricated, strong friction will occur between them. The dry friction between metal surfaces not only increases the power consumption of the engine and accelerates the wear of the working surfaces of the parts, but also may burn the working surfaces of the parts due to the heat generated by the friction, resulting in the failure of the engine to run.
Automotive engine lubricants include oil and grease
Function of oil:
1. Lubrication: oil forms a continuous oil film between all friction surfaces of moving parts to reduce friction between parts.
2. Cooling: oil flows over the working surface of parts during circulation, which can reduce the temperature of parts.
3. Cleaning: the oil can take away the metal debris generated on the friction surface and wash away the carbon deposits on the cylinder, piston, piston ring and other parts.
4. Sealing: The oil film attached to the cylinder wall, piston and piston ring can play the role of sealing and leakage prevention.
5. Rust prevention: oil can prevent parts from rusting.
In fact, the role of engine oil is more than that. It has many kinds and complex components. We will talk about it later.
The oil pump is the most important part in the lubrication system. Its function is to ensure that the oil circulates in the lubrication system and can deliver a sufficient amount of oil at a high enough pressure to the lubrication parts at any engine speed.
The structure of oil pump can be divided into gear type and rotor type.
The advantages of gear oil pump are high efficiency, small power loss and reliable operation; The disadvantage is that the intermediate transmission mechanism is required, and the manufacturing cost is relatively high.
The advantages of rotor type oil pump are compact structure, large oil supply, uniform oil supply, low noise and high oil suction vacuum. Rotor pumps are widely used in modern engines.
Reasons for failure of the engine automatic start stop system:
The battery of the vehicle is low;
2. The opening conditions of the start stop function are not met;
3. The automatic start stop switch is damaged;
4. The sensor for automatic start stop is damaged.
The use of engine start stop technology is that as long as you directly step on the brake pedal during driving, the engine will automatically shut down about two seconds after the vehicle stops completely, and the engine will remain shut down when you keep stepping on the brake pedal.
As soon as the brake is released or the steering wheel is turned, the engine will automatically ignite, and you can step on the accelerator to start immediately. The whole process is in D gear. The engine start stop technology is to stop the engine automatically when the vehicle stops temporarily (such as waiting for a red light) during driving.
