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 S7 introduce

The all-new Audi S7 sports model is synonymous with "excellent performance" and "dynamic design". It is equipped with Audi's new 4.0-liter V8 TFSI twin turbocharged fuel direct injection engine, with a power output of up to 309 kilowatts (420 horsepower). Due to the use of new "cylinder on-demand" technology, the average fuel consumption per 100 kilometers is only 9.6 liters and 9.7 liters, respectively. With advanced chassis, lightweight body, and exquisite interior, Make the all-new Audi the perfect masterpiece in the sports car market The S7 is developed based on the Audi A7, which is also the first generation model of this series The S7 Sportback and the regular Audi A7 Sportback, although not significantly different in appearance, have added some masculine muscle lines on the basis of their original luxury, showcasing a full sense of sportiness, including the addition of lower turbulence on the front bumper, honeycomb shaped left and right lower air intakes, and the addition of body side skirts. The rear bumper also adds lower turbulence, and the exhaust tailpipe is changed to a dual sided four out setting, At the same time, it comes standard with 19 inch aluminum alloy wheels, fully boasting the title of S7 Sportback in terms of performance
