Engine external cleaning is necessary. The following are the impacts of not cleaning the engine for a long time: 1. A large amount of sludge will form and adhere to the inner walls of the cylinders. The resulting pressure directly hinders the smooth movement of the pistons, and the high temperature inside the engine cannot be dissipated through oil circulation, leading to a decrease in engine power and a sharp increase in fuel consumption. 2. Due to the presence of sludge, the lubrication effect is reduced. The sludge is difficult to dilute with oil, and the mechanical friction will intensify during cylinder movement, increasing the load on the crankshaft rotation and causing severe damage to the engine. 3. If the sludge is not cleaned for a long time, it will accumulate more and more. After noticing a decrease in engine power, even replacing the new oil cannot resolve the issue of space compression, and it may cause the new oil to deteriorate. During the cleaning process, hardened sludge may break off and block the oil passages, so it is recommended to have the cleaning done at a professional 4S shop.

What is the difference between a tachometer and an odometer?

Here are the differences between a tachometer and an odometer: 1. Position: Generally, the tachometer is on the left side and the speedometer is on the right. 2. Markings: The tachometer is marked from 0-6000 RPM, while the speedometer is marked from 0-220 km/h. Below is additional information: 1. Position: The odometer (mileage meter) is located below the tachometer and displays the distance traveled in numerical form. 2. Significance: The engine's RPM relates to the number of work cycles per unit time or the effective power output of the engine, meaning the engine's effective power varies with RPM. Therefore, when stating the engine's effective power, the corresponding RPM must also be specified.

What Causes Auto Hold Failure?

Auto hold failure is caused by a malfunction in the ABS pump. Below is an introduction to related content: 1. Auto Hold: The foreign term for auto hold is AUTO-HOLD, which refers to an automatic braking function. When this function is activated, such as when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying operations by avoiding the use of the handbrake or electronic parking brake. For automatic transmission models, it also reduces the need for frequent shifting between D to N or D to P. 2. Precautions: Regardless of the situation when parking, it is essential to develop the habit of pulling the handbrake lever tightly when leaving the vehicle. When using the handbrake, the lever must be pulled tightly; otherwise, it is easy to forget to release it when starting, which can lead to severe wear on the rear brake pads if the vehicle is forced to move.

What Causes Powertrain Failure?

When pressing the accelerator, you may notice insignificant acceleration and insufficient power. This condition most commonly occurs when the engine is overheated or overcooled, or when there is a lack of engine oil. Below are detailed explanations: 1. Power reduction: While driving, you may distinctly feel that the engine's acceleration is not significant when stepping on the accelerator, accompanied by a noticeable drop in power and audible noises. Possible causes include the engine being too cold or too hot, or lacking oil. Generally, when these symptoms appear, potential issues should be considered from aspects such as ignition wires, fuel filters, fuel pumps, air filters, gasoline, spark plugs, and carburetors. First, check if the air filter needs replacement, if the spark plugs have reached the end of their service life, if the ignition coil is damaged, or if there is excessive impurity in the gasoline. The fuel pump should also be inspected. 2. Deceleration or acceleration: The engine may emit a whirring sound, which changes with the engine's RPM. Possible reasons include insufficient power steering fluid—refill if necessary; potential damage to the generator's bearings; or similar noises caused by malfunctions in the water pump or power steering pump.
