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 6 Series introduce

The BMW 6 Series is a car specially designed by BMW Germany for sophisticated drivers. It was introduced in 1976 and discontinued in 1989. During this period, its sales reached 86000 units, making it the most successful box car in BMW's history After a 14 year hiatus, BMW decided to revive the 6 Series and once again enter this large luxury sports car market, showcasing the core concept of the BMW 6 Series in GT racing, combining the advantages of sports cars and luxury RVs The previous models of BMW's sporty two door cars have also perfectly achieved this integration. In terms of exterior design, the 6 Series maintains the typical dynamic style of BMW Coupe, with a long hood, low roof lines, and front and side skirts giving the car a dynamic and elegant posture. To distinguish it from other models, the headlights, engine cover, radiator grille, and front air vents have all been redesigned. By introducing new elements such as LED brake lights in the tail light design, in addition to greatly reducing reaction time, the size and brightness can be adjusted according to different environments. The BMW v8 engine provides power for the 6 Series. BMW is known for its advanced technological development, and a series of LED brake lights have been introduced. The application of high-tech projects has maintained BMW's leading position in the automotive industry. The 6 Series has also adopted many advanced scientific research achievements. The new 6 Series has a body length of 4820mm and a width of 1800mm, which is even wider than the 5 Series. Such a large body shape will inevitably increase the weight of the body, and excessive body weight will greatly affect the acceleration and handling of the 6 Series. Therefore, BMW has used a large amount of aluminum alloy and composite materials on the body of the 6 Series, In order to achieve the goal of reducing weight, carbon fiber reinforced plastic materials are 50% lighter than steel and 35% lighter than aluminum, which can effectively reduce the weight of the vehicle body. The rigidity is three times that of other materials in the central control area (10 sheets), and the collision resistance and safety are quite good, which has always been an ideal material for the automotive industry. However, due to the lack of stamping equipment, carbon fiber used to be produced manually. BMW has developed a set of stamping equipment with a self weight of 200 tons and a pressure of 1800 tons, which is the world's first mass-produced carbon fiber roof, and has begun trial use on the new 6 series. The 6 series also uses an overhead display (hud) system that is only available on aircraft, which can directly display some important information. Projected onto the windshield of the car, including navigation direction, speed, and active cruise control display. The core functions related to driving in the car are operated through the i-drive controller and buttons attached to the steering wheel, but the i-drive control button is placed on the right side of the gear lever and requires arm extension to reach. Other secondary functions and comfort equipment control are arranged in a distance that is easily accessible to the other (2) cars and front seat passengers, Very convenient. Users can also choose a panoramic glass roof that is much larger than a regular electric sunroof, allowing more sunlight to enter the luxurious interior of the car. Dynamic driving and active steering systems are optional equipment for the 6 Series, which can greatly eliminate the body roll caused by vehicle turning and increase the comfort of passengers inside the car. The active steering system, on the other hand, changes the steering ratio based on the vehicle speed through a stepper motor. At lower speeds, the steering sensitivity increases, and larger wheel turns can be achieved by turning the steering wheel at a smaller angle. This situation is very useful for drivers driving on urban roads or parking and turning around. As the speed increases, the steering becomes more sensitive. Accurate, ensuring driving stability and comfort. The BMW 6 Series engine is equipped with Dynamic Stability Control (DSC) and Dynamic Traction Control (DTC) systems. In addition, the Driving Dynamics Control (DDC) technology used in the BMW M3 and M5 models is also used in the new 6 Series, which is controlled through a "SPORT" button located on the center console The DDC function can increase the sensitivity of the throttle response, improve acceleration ability, and provide a more direct response to the power assisted steering mechanism, thereby increasing the driving pleasure of the driver. In terms of power, there is also the option to choose a sequential manual transmission (SMG), which can be changed by the paddles on the steering wheel or the gear lever. As for the interior, we have always trusted BMW. The 6 Series adheres to BMW's consistent style, perfectly combining luxury and practicality. The bright colors are more in line with its sporty characteristics, and there are multiple configurations to choose from. As a representative of luxury cars, the BMW 6 Series [2] also has many commendable features. In terms of sound configuration, the new BMW 6 Series is equipped with 8 features. A hi fi sound system with speakers, 9 space seats, and 6 CDs create a home theater effect
