The reasons why cruise control doesn't work are: 1. The vehicle speed does not meet the limiting conditions for cruise control activation; 2. The cruise control system malfunctions; 3. The driver presses the brake pedal or shifts to neutral, causing the cruise control to be automatically deactivated. The principle of cruise control is to regulate the throttle opening size by controlling the signal output from the electronic throttle sensor through the cruise control system, thereby achieving control over the vehicle's speed. After the cruise control function is activated, the cruise control module precisely calculates the required throttle opening angle to maintain the current cruising speed based on the signal from the electronic throttle sensor, ensuring accurate coordination between air and fuel to achieve the set cruising speed.

Why does the car have no response when starting despite having fuel and electricity?

It might be caused by poor contact of the starter solenoid coil. In this case, it is recommended to gently tap the starter solenoid coil with a short iron pipe. If this doesn't work, the starter may need to be replaced. When using the key to start, please remember the following precautions: 1. Do not turn to 'start': After the engine starts, do not turn the key back to the 'start' position, and do not use a modified key. Otherwise, the key may not automatically return to the 'on' position, causing the starter to continue running, which could damage the starter or lead to a fire due to excessive load. 2. Do not crank for too long: The ignition switch should not remain in the 'start' position for more than 5 seconds. If the engine fails to start on the first attempt, wait at least 30 seconds before trying again. While driving, never turn the ignition switch to the 'lock' or 'acc' position, as this could disable the steering wheel, brakes, and power steering system.

What is the fuel consumption of the 1.5T Civic?

1.5T Civic fuel consumption: Manual transmission: around 6.8, automatic transmission: around 7.5. The fuel consumption of a car varies slightly depending on each person's driving habits and skills. More stable driving habits result in lower fuel consumption. If you usually prefer aggressive driving, overtaking, and other high-RPM operations, the fuel consumption will increase appropriately. Here are some methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning malfunctions are a significant cause of high fuel consumption. Poor cooling performance will require higher fan speeds and lower temperatures to achieve a comfortable effect. 2. Frequent sudden braking: Frequent sudden braking is the main reason for persistently high fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid excessive air conditioning in small-displacement cars: For vehicles exposed to the sun, it is not advisable to turn on the air conditioning immediately after getting in. First, open the windows, set the fan to a higher speed without turning on the air conditioning, and expel the hot air inside the car. Wait until the vehicle has cooled down moderately before turning on the air conditioning.

How Long Should You Wait to Wash Your Car After Driving on the Highway?

Generally, it is better to wait 15 to 20 minutes after exiting the highway before washing your car, allowing the engine and other systems to cool down. After driving on the highway, both the brakes and the engine are in the process of dissipating heat. If you wash the car immediately, using cold water to rinse the brake discs may cause the brake discs to warp in mild cases, or even lead to brake system failure in severe cases, affecting driving safety. Below are some relevant points: 1. Precautions for car washing: Do not wash the car before the engine has completely cooled down, as this can cause premature aging of the engine. Avoid washing the car under direct sunlight, as it may leave dried water spot marks on the body. Do not wash the car in extremely cold weather, as water freezing can cause the paint film to crack. 2. Highway driving safety: Before entering the highway, clean the windshield and rearview mirrors in time to eliminate potential safety hazards.

Is it better to install internal or external tire pressure monitoring?

Tire pressure monitoring devices are better when installed internally, and the detection effect is also excellent. Below is the relevant information: 1. The role of tire pressure monitoring: The function of tire pressure monitoring is to automatically and continuously monitor the tire pressure during vehicle operation, and to alert the driver in case of tire leaks or low pressure to ensure driving safety. 2. External sensors: The principle involves using a pin to push open the valve core, where the pressure impact received by the sensor reflects the internal tire pressure. The sensor cleverly utilizes the thread of the dust cap for fixation on the valve stem. 3. Internal sensors: These are installed inside the tire, replacing the original valve with one that includes a sensor. The external part is minimal and does not protrude beyond the wheel hub; once installed, it is essentially a permanent solution.

Reasons for Abnormal Car Vibration While Driving

There are five main reasons for car vibration, analyzed as follows: 1. Cold Start Vibration: The primary cause is incomplete fuel combustion, leading to insufficient power. Low ignition energy during startup, especially when fuel and lubricant temperatures are low, requires more throttle to meet power demands. Over time, the spark plug gap gradually widens, reducing ignition energy and fuel atomization, causing body vibration. Additionally, aging ignition coils, spark plug high-voltage wires, or electrical leaks can also decrease ignition energy. 2. Shock Absorber System Issues: The shock absorber system filters engine vibrations during operation. If the shock absorbers fail, vibrations transmit directly to the steering wheel and cabin, affecting driving. At idle, turning on electrical systems can easily cause vibrations. The engine load increases with electrical usage, lowering idle speed. To compensate, the engine automatically raises RPM, often causing vibrations when using systems like the AC. Such vibrations likely indicate aging shock absorbers needing replacement. 3. Tire Problems: When replacing tires or rims, wheel balancing is essential. Uneven weight distribution can cause steering wheel vibrations. If weight imbalance is detected, lead weights should be added inside the rim to balance tire weights. Both standard steel rims and lightweight aluminum rims can deform or crack under stress. Deformed rims cause driving vibrations, as do unbalanced or misaligned rims. 4. Throttle Body Issues: A dirty throttle body or excessive injector carbon buildup can prevent proper throttle closure or cause motor jamming, leading to high idle speed. Carbon deposits also cause vibrations, especially during startup, where the engine may shake more severely or fail to start on the first try. Therefore, when vibrations occur, first inspect the throttle body and injectors. If dirty or carbon-clogged, clean them promptly with appropriate cleaners. 5. Unstable Oil Pressure: If vibrations persist after cleaning engine carbon, throttle body, and replacing gaskets, check fuel supply pressure and intake pressure sensors at a repair shop. Abnormal fuel pump pressure or faulty sensor readings can cause body vibrations.

What are the components of a steering gear?

Steering gear is composed of various gears and racks. The following are relevant introductions: 1. Working principle of steering gear: The working principle of the steering gear is that when the car is driving straight, the steering control valve connects the working fluid pumped by the steering oil pump to the oil tank, and the steering oil pump is in an unloading state. When the car needs to turn right, the steering control valve connects the working fluid pumped by the steering oil pump to the R chamber and connects the L chamber to the oil tank, causing the left and right wheels to deflect to the right through the transmission structure, thereby achieving a right turn. 2. Classification of steering gears: Steering gears include rack and pinion steering gears, worm and sector steering gears, and recirculating ball steering gears.
