What is the working principle of an exhaust brake?

The principle of exhaust braking is to transform the engine, originally a power output device, into an air compressor that becomes a power-consuming device. Application areas of exhaust braking: Exhaust braking is widely used in large diesel vehicles. It involves installing a regulating valve on the engine exhaust pipe. The closing of this valve increases the pressure during the exhaust stroke, utilizing the generated negative pressure to obtain braking force. The regulating valve is generally controlled by compressed air or vacuum, driven by a mechanism, and in most cases, it shares the same power source as the main brake. Precautions for using exhaust braking: Engine braking cannot replace service braking for emergency braking, nor can it be used for parking braking. Engine braking can be used simultaneously with service braking. The throttle pedal should be at the zero position.

What Causes the Engine Light to Illuminate on the Dashboard?

The reasons for the engine light illuminating on the dashboard are as follows: Substandard Fuel Quality: This can prevent the air-fuel mixture in the engine from burning completely, leading to engine abnormalities and triggering the fault light. In this case, simply switch to fuel that meets quality standards. Severe Spark Plug Carbon Buildup: This can cause unstable idling, poor acceleration, backfiring during rapid acceleration, and other issues. Spark plugs should be cleaned regularly, and if they are severely aged, they should be replaced. Engine Knocking: This usually occurs when the compressed gas ignites prematurely before reaching the optimal ignition point due to certain factors. The resulting combustion creates a strong impact opposite to the piston's movement, leading to knocking. Engine Misfire: This can result in increased fuel consumption, black smoke emissions, severe shaking, louder engine noise, and poor acceleration. Causes of misfires may stem from the ignition system, fuel supply system, or other components.

What are the symptoms of a bad CV joint in a car?

Symptoms of a faulty CV joint in a vehicle are as follows: CV joint abnormal noise: It can cause abnormal noise from the CV joint during acceleration or turning. Most CV joint failures are caused by damage to the rubber boot of the CV joint, which leads to leakage of lubricating grease inside the CV joint, resulting in abnormal wear. After abnormal wear occurs, the clearance in the CV joint increases, leading to abnormal noise. Function of CV joint: The CV joint in a car is a very important component. This part is located at the end of the drive shaft and serves to connect the drive shaft to the wheel. Without the CV joint, power cannot be transmitted to the wheels. During routine maintenance, lift the car with a lift and check the rubber boot of the CV joint.

What is the function of the 'A' button in a car?

The 'A' button in a car stands for the Auto Hold function, which enables the vehicle to automatically apply the brakes based on actual driving conditions. When to use Auto Hold: This function is particularly useful when driving on slopes or during frequent stops and starts. How Auto Hold works: The vehicle's onboard computer automatically measures data such as wheel torque and body level to determine if there's a tendency for the car to roll. If a rolling tendency is detected, the computer applies appropriate braking force to keep the vehicle stationary. When the accelerator is pressed to start moving, the Auto Hold function automatically disengages, allowing for smooth driving.

What are the internal structures of an automatic transmission?

Automatic transmission internal structures include: torque converter, planetary gear transmission mechanism, hydraulic control system, and oil filter. An automatic transmission is a gear-shifting device that can automatically shift gears based on the vehicle's speed and engine RPM, as opposed to a manual transmission. It mainly consists of four types: hydraulic automatic transmission, mechanical continuously variable automatic transmission, electronically controlled mechanical automatic transmission, and dual-clutch automatic transmission. The automatic transmission uses planetary gear mechanisms for shifting, automatically adjusting gears according to the degree of throttle pedal and changes in vehicle speed. The driver only needs to operate the accelerator pedal to control the speed.

How to Change the Oil in an Automatic Transmission Machine?

Steps for changing the oil in an automatic transmission machine: 1. First, add the transmission FLUSH cleaner into the transmission to allow the cleaner to break down the oil film on the gears as much as possible; 2. Lift the car, switch between D and R gears, and run for 5 to 10 minutes. These two steps will clean the automatic transmission; 3. Drain the old oil. Although the automatic transmission undergoes one oil change, long-term use makes it impossible to clean the transmission thoroughly in just one cycle. This cleaning process needs to be repeated twice; 4. Add 2 to 3 liters of new transmission oil, repeat the second step to circulate again, and remove as much sludge as possible from the gears before draining the oil; 5. Remove the transmission pan; 6. Add new oil by pouring the prepared automatic transmission oil into the system to complete the process.
