What is the name of the metal pipe under the engine spark plug?

The metal pipe under the engine spark plug is called the spark plug wire. Function of spark plug wire: The spark plug wire serves as the medium through which the ignition coil transfers energy to the spark plug. When symptoms such as car shaking or jerking occur, it is important to inspect the spark plug wire and replace it if necessary. Composition of spark plug wire: Automotive spark plug wires, generally referring to distributor wires, transmit the high-voltage spark from the distributor to the spark plug, enabling ignition and combustion within the cylinder to drive the engine. Spark plug wires are broadly divided into four parts: first, the conductive material; second, the insulating rubber; third, the ignition coil connector; and fourth, the spark plug connector. Some spark plug wires are also wrapped in a layer of heat-resistant material to prevent them from being burned out.

Is Polishing and Waxing Necessary for New Cars?

New cars require polishing only when there are numerous scratches. New car maintenance methods: The paint on new cars is very glossy and vibrant, but after driving for a while, the paint on different cars can vary significantly. Generally, new cars do need waxing, which is currently the most common and cheapest way to maintain the car's paint. Dealing with aging paint: If the car's paint has aged severely, the entire vehicle's appearance will look lifeless, turning it into a true "old car." After waxing, it can effectively prevent damage caused by UV rays and corrosive substances such as bird droppings and kitchen fumes to the car's paint.

Where is the vent hole of the headlight located?

The vent hole of the headlight is located at the lower left position of the steering wheel. Function of the vent tube: Whether it's a regular halogen headlight, xenon headlight, or LED headlight assembly, there is a vent rubber tube on the rear cover. When the headlight is turned on and during use, a large amount of heat is generated. The function of the vent tube is to expel this heat as much as possible outside the headlight to maintain the normal operating temperature of the headlight and ensure its stable performance. Principle of fog expulsion: Moisture in the air can enter the headlight through the vent tube and condense on the lens. As moisture accumulates, water droplets will flow down the lens. This phenomenon mostly occurs due to significant temperature differences and is most common in winter and rainy seasons. After the headlight has been on for a while, the fog will be expelled through the vent tube along with the hot air, which generally does not damage the headlight or electrical circuits.

What are the reasons for slow acceleration in Cummins engines?

Here are the specific reasons for slow acceleration in Cummins engines: Clutch Slipping: Clutch slipping mainly manifests as the vehicle's speed not increasing with the engine's RPM during acceleration, preventing the engine's power from being fully transmitted to the drive wheels, resulting in weak driving performance, especially noticeable when going uphill. The primary causes of clutch slipping are insufficient friction from the clutch friction plate; shifting gears too early or disengaging before the clutch is fully engaged; prolonged driving with the clutch partially engaged or coasting with the clutch pedal depressed; and abnormal wear of the clutch plate due to aggressive throttle application when the gear is not fully engaged or disengaged. Fuel System Malfunction: Clogged fuel injectors, leaking fuel lines, reduced fuel pump efficiency, or a blocked fuel filter can all lead to weak performance when driving uphill.

How many kilometers can Castrol Edge fully synthetic oil run?

It can run 8,000 to 10,000 kilometers. Extending usage duration: If you want to extend the mileage, it is recommended to check once a month or before driving. Take out some oil from the dipstick to check the oil level and quality. If it still feels good, continue using it. If the quality is poor, replace it immediately to reduce damage to the car. Identifying oil quality: Smell test: Bring the dipstick close to your nose and smell it. If there is a strong sour odor, it means the oil has deteriorated and should be replaced. Finger rub test: Rub the old oil between your thumb and index finger repeatedly. Good quality oil will feel lubricated, have few wear particles, and no friction. If you feel impurities, poor viscosity, or even a rough texture, it should be replaced.

What Causes Increased Noise and Vibration After Replacing the Timing Belt?

The reason for vehicle vibration after replacing the timing belt may be incorrect crankshaft connection. Issues with belt connection include: The timing belt ensures accurate intake and exhaust timing by connecting to the crankshaft with a specific transmission ratio. Belts are used instead of gears for transmission because they produce less noise, have minimal self-variation, and are easier to compensate. Obviously, the lifespan of a belt is shorter than that of metal gears, so it needs to be replaced regularly. Often, there is vibration at idle after replacing the timing belt. Misalignment of timing marks: If it is confirmed that the vibration is caused by the belt replacement, and the accessory model is correct, it may be necessary to check whether the timing marks are properly aligned. Deviation can cause vibration and lack of power, so a recheck is required.
