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

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)
