What Causes Transmission Overheating in the New Focus?

1 Answers

The New Focus is equipped with a dry dual-clutch transmission, which primarily relies on airflow for cooling. If the vehicle frequently stops and starts in continuous congested traffic, the transmission's repeated gear shifts can easily lead to overheating. Below is a detailed introduction to the dry dual-clutch transmission in vehicles: 1. Working Principle: It utilizes two clutches that operate alternately. The difference from a wet dual-clutch lies in the medium connecting the driving and driven plates. Wet dual-clutch transmissions mainly rely on oil, whereas dry dual-clutch transmissions primarily depend on air. 2. Basic Structure: The friction plates of a dry dual-clutch lack sealed oil grooves and require air cooling for heat dissipation. 3. Pros and Cons: The advantage of a dry dual-clutch is its fast gear shifting speed, while the drawback is its relatively low torque capacity.

Is it safe to drive with insufficient tire pressure?

Tire pressure is insufficient when it is recommended not to continue driving, because driving with insufficient tire pressure is very dangerous. For safety reasons, it is best to stop immediately. Continuing to drive with insufficient tire pressure will have the following effects: 1. It will increase the contact area between the tire tread and the road surface, increasing driving resistance and fuel consumption. 2. It will cause severe wear on both sides of the tire, and the sides of the tire are the most fragile parts. 3. It will increase the friction coefficient, leading to abnormal heating of the tire, a sharp rise in tire temperature, softening of the tire, a decrease in strength, and an increased risk of a blowout.

Should You Warm Up the Car Before an Oil Change?

It is necessary to warm up the car before an oil change, typically for about 5 minutes. Below are the benefits of warming up the car before an oil change: 1. Engine oil is a liquid with a certain viscosity. If the temperature is low, the viscosity will be higher, making it difficult for the oil to flow out when the oil pan drain plug is removed. 2. There is some sludge inside the engine, which will soften after warming up the car, allowing it to be flushed out along with the old oil. 3. Removing the oil filter becomes easier after warming up the car. During an oil change, the oil filter should be replaced as well. There is a lot of oil and sludge around the oil filter, making it difficult to remove when the engine is cold. Additional note: When changing the oil, make sure to completely drain the old oil before adding new oil. Otherwise, the old oil can contaminate the new oil, reducing its lubrication effectiveness and performance.

What are the symptoms of a faulty electronic throttle body?

Electronic throttle body failure may cause the engine warning light to illuminate, engine idle shaking and unstable idle, stalling at low speeds, and other phenomena. Here is relevant information: 1. Use a computer diagnostic tool to check the engine module. If there are no permanent fault codes, replacement is generally not required. Read the throttle body's data stream to check the two position sensors and throttle opening. If the opening is large, first clean the carbon deposits on the throttle body, then perform throttle initialization. 2. If the throttle position sensor and motor have poor line contact, open circuit, or short circuit, check the throttle wiring harness connector for rust, water ingress, or widened connector tabs in case of poor contact. For open or short circuits, inspect the related throttle wiring by measuring voltage and circuit continuity.

Is there a fine for not wearing seat belts in the back seat on the highway?

If passengers are found not wearing seat belts on the highway, whether in the front or back seats, a fine of 50 yuan will be imposed according to the "Road Traffic Safety Law of the People's Republic of China"; for drivers who do not use seat belts as required while driving on the highway, a fine of 200 yuan and 2 demerit points will be imposed. More details are as follows: 1. Article 51 of the "Road Traffic Safety Law" states that when a motor vehicle is in motion, the driver and passengers must use seat belts as required, and motorcycle drivers and passengers must wear safety helmets as required. 2. Article 89 states that pedestrians, passengers, and non-motor vehicle drivers who violate the road traffic safety laws and regulations regarding road usage will be given a warning or fined between 5 and 50 yuan; if a non-motor vehicle driver refuses to accept the fine, their non-motor vehicle may be impounded.

Which Subject to Retake After Losing All 12 Points?

After losing all 12 points, you need to retake Subject 1. If a driver accumulates 12 penalty points during the probationary period, their license will be revoked, and they must undergo the entire learning process and retake the driving test. If the 12-point threshold is exceeded after the probationary period, the driver must attend a 7-day training course and retake Subject 1. Below are the details: 1. If a motor vehicle driver accumulates 12 penalty points within a scoring cycle, they must report to the traffic management department of the public security authority at the place where the driver's license was issued or where the violation occurred within 15 days to receive a 7-day education program on road traffic safety laws, regulations, and related knowledge. 2. After completing the education program, the vehicle management office must administer the Subject 1 test within 20 days.

What are the components of a car air conditioning system?

An automotive air conditioning system is generally composed of a compressor, condenser, evaporator, expansion valve, receiver-drier, pipes, and other components. Here is relevant information: 1. The car air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle. It provides a comfortable environment for passengers, reduces driver fatigue, and improves driving safety. The air conditioning system has become one of the indicators to measure whether a car is fully equipped. 2. Compressor: The compressor is the "heart" of the air conditioning refrigeration system. It is a power source that circulates the refrigerant within the system. Its function is to compress the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure refrigerant, completing the transformation process from gas to liquid.
