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

BMW 328Li introduce

The BMW 328Li has no significant configuration differences in the front part of the car. The hood extends in a wedge-shaped shape from the upper edge of the headlights to the lower edge of the front windshield, and the multi edged design makes the new hood look more dynamic. The enlarged front grille is a prominent feature of this generation of 3 Series, and the new headlight group closely connected to the grille is more aggressive. The chrome plated decorative strip in the fog light area, which is unique to the new 3 Series, is firmly covered by black tape, But the overall lines are clearly exposed. The side of the BMW 328Li can be clearly seen to be different from the overseas version of the 3 Series. The size of the rear door has a more obvious increase, and the line at the back of the side skirt tends to be more straight. This also means that it will be an authentic domestic new 3 Series sedan, which will provide more abundant rear seating space for Chinese consumers. The BMW 328Li will be equipped with a brand new 4-cylinder turbocharged engine, The maximum power is 240 horsepower, matched with a brand new 8-speed automatic transmission. The first six gears of the new transmission adopt a 1:1 gear ratio, and the last two gears are super ratio gears, which can help reduce fuel consumption during high-speed cruising
