What Causes Engine Idle Vibration After Water Rinse?

Because a small amount of water entered the high-voltage line during car washing, and the engine air filter element got wet, leading to increased intake resistance and water entering the combustion chamber, resulting in poor ignition system performance. Here are the related explanations: 1. Ignition system issues: Check the working condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or inadequate spark plug firing can also cause such fault symptoms. 3. Unstable oil pressure: It is recommended to go to a professional repair shop to check whether the fuel supply pressure and intake pressure sensor are normal. If the fuel pump supply pressure is abnormal or the intake pressure sensor values are incorrect and not working properly, it can cause body vibration.

Approximately how many liters of fuel does a car consume per kilometer?

Regarding the fuel consumption of a car per kilometer, there is no absolute answer as it depends on factors such as engine displacement, vehicle model, driving habits, etc. Here is some relevant information: Relationship: For cars, a higher km/L (kilometers per liter) value is better than a lower one. For example, comparing 1km/L and 2km/L, the latter clearly indicates a more fuel-efficient vehicle. Factors affecting car fuel consumption: The amount of fuel a car consumes is not only related to the car itself but also to the driver's driving habits and road conditions. If the driving habits are poor and the car is frequently driven on congested roads, the fuel consumption will inevitably be relatively high.

How Big is a 30% Car Sticker?

How big a 30% car sticker is depends on the surface area of the car. The result varies depending on the car model. Below is additional information: Car stickers or 30% coverage: You need to bring the required documents and invoice, drive the color-changed car to the vehicle management office to undergo inspection procedures. The staff at the vehicle management office will record the changed body color, take new photos, and update the vehicle registration certificate, among other procedures. Penalties: If you do not report to the vehicle management office and apply the sticker privately, you will be ordered to remove it by traffic police if caught, and may also face fines. Advertising signs: Spraying, pasting signs, or body advertisements on motor vehicles may result in a warning or fine from the traffic management department of the public security authorities.

Is it harmful to wash a hot engine once?

Occasionally doing it once won't cause harm. However, frequent washing like this can lead to thermal contraction from the temperature difference, potentially shortening the engine's lifespan. Here's relevant information: Overview: The car engine is the device that provides power to the vehicle, determining its performance, fuel efficiency, stability, and environmental friendliness. Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others. Others: Common gasoline and diesel engines belong to reciprocating piston internal combustion engines, capable of converting the chemical energy of fuel into mechanical energy for piston movement and outputting power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have lower manufacturing costs. Diesel engines have higher compression ratios, greater thermal efficiency, and better fuel economy and emission performance compared to gasoline engines.

How many seconds does it take for a car to run 100 meters?

A regular car takes about 8 seconds to cover 100 meters, while a supercar might only need 3 seconds. Here is some relevant information: 0-100m acceleration: Also known as 0-100km/h acceleration, it refers to the time required for a car to accelerate from a standstill (0km/h) to 100km/h. The 0-100m acceleration is the most intuitive reflection of a car's power. The shorter the time required for 0-100m acceleration, the stronger the car's acceleration performance. Impact of fuel type: Since fuel octane ratings vary, differences in methane values can also affect the 0-100m acceleration results. The remaining fuel in the car during testing can influence the vehicle's weight, leading to variations in the results.

What is the function of the accres button in a car?

The accres button in the car is related to the cruise control system. Below is relevant information: Introduction: When using cruise control, if encountering a steep downhill slope, the vehicle speed may increase, exceeding the set speed, and it cannot be used for deceleration. Therefore, some drivers receive speeding tickets while using cruise control. Cruise control only adjusts the throttle automatically to maintain the set speed. When the speed exceeds the set value, it automatically reduces or even stops fuel supply. However, it does not automatically apply brakes to decelerate. On downhill slopes, if the downward force exceeds the motion resistance (including wind resistance, rolling resistance, engine braking force, etc.), the vehicle will accelerate. Suggestion: When encountering a steep downhill, it is recommended to shift to S gear because S gear can increase engine speed compared to D gear, enhancing engine braking force. This reduces the need for foot braking, preventing excessive heat generation and brake wear. However, D gear is generally sufficient for normal road conditions.

Is it okay to leave a new car unused for 3 months?

Leaving a car unused for several months can easily cause damage, but the specific situation depends on the car's condition. Generally, a car should not be left idle for more than two weeks, otherwise the following problems may occur due to prolonged inactivity: Engine and transmission issues: Firstly, the engine oil will deteriorate over time, leading to lubrication and wear problems. It may even solidify. Not only the engine oil, but various coolants can also deteriorate. Naturally, the engine will suffer under such conditions. Battery drain: If a car is left unused for a long time, the battery is prone to losing charge, making it difficult to start the car. Brake system problems: When parking, drivers usually engage the handbrake, which keeps the handbrake cable in a tense state, thereby shortening its lifespan. This is especially a threat for cars not parked on level ground.
