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

Fiat CROMA introduce

The new Croma station wagon has a more dynamic and modern exterior design, although only modified from the current model, the effect is indeed immediate. The new car incorporates the design elements of the new generation Fiat, and we can see the shadow of the new Punto and Brava. The engine hood of the new car has clear lines and a strong sense of power. The elongated front headlights are very dynamic, and the horizontal grille has been replaced by a chrome plated mesh. The tail light shade is darker and cooler than the old model, and the new design of the rear bumper is more dynamic. The cabin of the new car has also been decorated, full of Italian style luxury. The seats are made of leather and fabric. The newly designed instrument panel and steering wheel are very elegant. The standard configuration of the new Croma is already very rich, including rain sensors, reverse radar, tire pressure sensors, cruise control system, ABS anti lock braking system, EBD brake force distribution system, ESP body stability control system, front dual airbags, side airbags, air curtains, and knee airbags. In addition, the new car also has a large number of optional configurations, Including DVD audio and video system, navigation and information system with Bluetooth function, high fidelity audio system, etc. The second row seats can be fully folded, and when the passenger seat is folded down, it becomes a small coffee table. The cargo space can be conveniently increased from 500 liters to 1610 liters. Fiat provides five engines for users to choose from for the new Croma, including two gasoline engines and three Multijet turbocharged diesel engines. The entry-level power is a 1.8-liter gasoline engine with a 140 hp output, and the top-level power configuration is a 2.4-liter turbocharged diesel engine with a 200 hp output. The diesel engine comes standard with a six speed automatic transmission, while the gasoline engine comes standard with a five speed manual transmission. 2.2 A gasoline engine can be equipped with a six speed automatic transmission, while a 1.9-liter diesel engine can be equipped with a five speed manual transmission (Kevin Lee)
