What does engine power misrepresentation mean for domestic cars?

Engine power misrepresentation refers to the situation where the power rating labeled on the engine is significantly higher than the actual power output obtained through standardized national testing. In simple terms, the actual power of the engine falls far short of the labeled power value, and such labeling is termed as misrepresentation. For consumers: Misrepresentation is purely deceptive and irresponsible. Engines with misrepresented power ratings are generally produced by obscure manufacturers that lack legal oversight, resulting in unguaranteed engine quality and after-sales service. Hazards of misrepresentation: Misrepresentation serves merely as a means for unscrupulous businesses to seek exorbitant profits. Its existence not only disrupts the healthy development of the automotive engine market and undermines the establishment of domestic brands but also severely harms consumer interests.

What Causes the Engagement Impact Noise When Starting with a Dual-Clutch Transmission?

It is normal for a dual-clutch transmission to produce metallic impact sounds under certain conditions. The following details the reasons for abnormal noises during the start-up of a dual-clutch transmission: Gear Shift Fork Noise: During the gear shifting process of a dual-clutch transmission, the final gear selection is completed by the shift fork, which can easily generate abnormal noises when operating. Additionally, the clutch assembly may also produce noises during the shifting process. Many car brands experience this phenomenon: Currently, many domestic brands using dual-clutch transmissions also encounter varying degrees of abnormal noises, although significant improvements have been made.

Is a tire pressure of 230kpa normal for cars in summer?

Is a tire pressure of 230kpa normal for cars in summer? A tire pressure of 230kpa is normal for cars in summer. According to the international GBT2978-2008 standard, the standard tire pressure for regular tires is 240-250kpa. Due to high temperatures in summer, the lower limit of the standard tire pressure is generally considered the normal range. However, if the car is often parked outdoors, the tire pressure can usually be about 100kpa lower than the standard. Therefore, a tire pressure of 230kpa in summer is normal. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Usually, an alarm will trigger if the pressure is below 180kpa or above 300kpa. At this time, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the original data, causing the tire pressure monitoring indicator to light up. In this case, simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor, which is used to monitor tire pressure, is directly installed inside the tire and connected to the tire inflation port. If the tire pressure sensor is damaged during driving, the tire pressure warning light will also illuminate. For sensor damage issues, only replacement with a new component is possible.

What's the reason for engine warning light and air conditioning not cooling?

Reasons for engine warning light and air conditioning not cooling: lack of refrigerant, dirty condenser. Detailed explanations of the reasons: Lack of refrigerant: Car air conditioners generally require refrigerant replenishment every 2-3 years, with some vehicles needing it annually. Even with excellent sealing, refrigerant can still escape, especially if there are minor leaks in the air conditioning pipes or condenser. Dirty condenser: During summer when poor air conditioning performance is noticed, testing may show no issues with the system and normal high/low pressure readings. When visiting a 4S shop for repairs, mechanics often recommend cleaning the radiator. The primary purpose of cleaning the radiator and condenser is to improve heat dissipation.

What gear should be used for manual transmission when going down a long slope?

It depends on the load and vehicle model. Generally, second gear is sufficient. The lower the gear, the stronger the car's power, but of course, the speed will be slower. When going downhill, it is advisable to use S gear or manual mode: You should alternate between using the brake and manual mode (low gear) to reduce brake wear. If you keep using D gear along with continuously pressing the brake pedal while going downhill, it will increase brake wear. Prolonged use of the brakes can cause the braking system to overheat, reducing braking effectiveness and compromising safety. When going downhill: The limiting gear is used as an auxiliary brake. By restricting the gear shift upwards, the engine is used as an auxiliary brake to reduce the working pressure on the brake pads.
