oil pump introduce

The function of the oil pump in the lubrication system: The oil pump is used to increase the oil pressure to a certain level and force it to the moving surfaces of various parts of the engine. Its structure often adopts a gear type oil pump. When the engine is working, the crankshaft drives the active gear transmission, and the passive gear rotates in the opposite direction. The oil in the suction chamber is then pressed into the oil outlet chamber along the tooth gap and pump wall. As the oil in the suction chamber is continuously carried away, suction force is generated in the suction chamber, The oil pump continuously sucks the oil from the oil pan into the suction chamber and simultaneously pumps a certain pressure of oil into the lubricating oil circuit. In the lubrication system, the oil pump is a device that can force the oil from the oil pan to be sent to the moving parts of the engine. It is used to increase the oil pressure and ensure a certain amount of oil. The oil pump is a component that forcibly supplies oil to various friction surfaces. Gear type and rotor type oil pumps are widely used in internal combustion engines. Gear type oil pumps have a simple structure and are easy to process, Reliable operation, long service life, high pump oil pressure, and widely used. The rotor shape of the rotor pump is complex and is often pressed by powder metallurgy. This type of pump has the same advantages as gear pumps, but it is compact in structure and small in volume)

Installation method of diesel engine oil pump:

Installation method for diesel engine oil pump: 1. First, drain all engine oil, remove the engine oil pan, and replace the oil pump assembly; 2. The oil pump is the main component in the lubrication system of a diesel engine. Its function is to increase the oil pressure to a certain level and force it to the moving surfaces of various parts of the engine. The structure of the oil pump can be divided into two types: gear type and rotor type; 3. Gear type oil pumps are divided into internal gear type and external gear type, generally referred to as gear type oil pumps. 1. From the hole where the oil pump is installed, rotate the flywheel to rotate the cam to the back; 2. Seeing a fork, adjust the throttle so that the fork is in the middle position of the hole, place the gear rack on the oil pump in the middle position, and then carefully install it. Then, remove the speed limit screw in the gear compartment to see if the fork is forked against the gear rack. If it is not, repeat step 2. The oil pump of a single cylinder diesel engine is located in the lower left corner behind the large flywheel. Replacement steps for the oil pump of a single cylinder diesel engine: 1. Remove the large flywheel, and the oil pump can be seen in the lower left corner; 2. Unscrew the three bolts; 3. Remove the oil pump; 4. Fill the new pump with engine oil and install it

Audi A4L introduce

The Audi A4L is an entry-level luxury B-class sedan produced by FAW Audi. The characteristics of this car are its atmospheric and stable body, meticulous workmanship, solid materials, rich configuration, spacious space, and good handling A4L was officially released on November 16, 2008, and the front face design of the new Audi A4L continues to use the family's expensive sports car design style. The price range of Audi A4L is 272800-578100. The domestic version of the new generation Audi A4 was officially named: Audi A4L. Audi A4L is a new car that Audi only launched in the Chinese Mainland market. The relationship between the new car and A6 and A6L is similar, and it is also after foreign models are made in mainland China, A model derived from changes in configuration and market demand. After higher level mid to high end luxury cars have chosen to be lengthened in China and received good market feedback, this idea is now extending to its lower level mid size car market. Compared with the European version of the Audi A4, the domestic version of the Audi A4L has lengthened the body length by 60mm, reaching 4763mm, and the wheelbase has been lengthened by 61mm, reaching 2869mm, Satisfying the higher requirements of Chinese users for rear passenger space
