Throttle assembly introduce

The function of the throttle valve assembly is as follows: 1. The throttle valve of a car is a controllable valve used to control the air entering the engine. After entering the intake pipe, it mixes with gasoline (different vehicles have different mixing parts) to become a combustible mixture gas, participating in combustion and doing work. It is one of the steps to provide power for the vehicle; 2. The throttle valve is the most important component of today's electronic fuel injection vehicle engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the car engine and controls the vehicle's travel speed; 3. The agility of a car's acceleration is closely related to the cleanliness of the throttle valve. The owner controls the throttle valve opening by stepping on the acceleration valve to achieve the goal of slowing down)

Installation position of throttle body

The throttle body is installed at the intake manifold of the engine. The throttle body mainly includes two types: traditional cable type and electronic throttle. The traditional engine throttle control mechanism works by connecting one end to the accelerator pedal and the other end to the throttle linkage plate through a cable (soft steel wire) or rod. The electronic throttle is mainly controlled by the throttle position sensor to control the opening angle of the throttle according to the required energy of the engine, So as to adjust the size of the intake volume. The throttle valve is installed in front of the manifold and behind the hose. The throttle valve is a controllable valve that controls the air to enter the engine. After the gas enters the intake pipe, it will mix with gasoline to form a combustible mixture, which burns and does work. The phenomenon of a broken throttle valve is: 1. The engine idle is unstable, and the high idle does not decrease continuously; 2. Difficulty in starting the engine; 3. Insufficient engine power, poor acceleration performance, and unstable operation; 4. The exhaust pipe of the car emits black smoke; 5. The engine malfunction light is on. The method to clean the throttle valve is: 1. Turn off the ignition switch and remove the negative pole of the battery; 2. Remove the throttle cable, intake hose, and screws securing the throttle valve in sequence; 3. Use cleaning agent to clean the throttle valve, and wipe any areas that cannot be cleaned with cotton thread

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
