Is DCT an Automatic Transmission?

DCT is an automatic transmission. DCT refers to the dual-clutch transmission. Here is more information about dual-clutch transmissions: 1. Definition of Dual-Clutch Transmission: A dual-clutch transmission is a type of automatic transmission. Vehicles equipped with dual-clutch transmissions drive similarly to traditional automatic transmission models. Unlike traditional automatic transmissions, dual-clutch transmissions do not have a torque converter; they are a type of mechanical automatic transmission with two power output shafts—one connected to the clutch and the other to the gear. The dual-clutch transmission uses a dual multi-plate clutch design, significantly reducing the vehicle's fuel consumption. 2. Classification of Dual-Clutch Transmissions: There are three main types of transmissions: AT (automatic transmission), DCT (dual-clutch transmission), and CVT (continuously variable transmission). The AT transmission is the most traditional type, consisting mainly of a torque converter, planetary gear set, hydraulic control system, electronic control system, and other components. The CVT transmission does not have fixed gear ratios, and there is no power interruption during driving.

DCT is indeed a type of automatic transmission, but it feels quite different to drive. I've driven my friend's Sagitar with a dual-clutch transmission, and the most noticeable thing is how quickly it shifts gears, especially when accelerating—it zooms through the gears, which feels really satisfying. However, during low-speed crawling, there can occasionally be slight jerks, similar to a beginner driving a manual. Compared to traditional AT transmissions, dual-clutch transmissions don’t have a torque converter and are structurally more like an automated version of a manual transmission. Fuel efficiency is quite good—it can save about half a liter per 100km in city driving compared to an AT car of the same displacement. If buying used, it’s advisable to thoroughly check the wear on the clutch plates, as repairs for this can be quite expensive.

How to Legally Modify an Engine?

Private modifications such as altering the engine's fuel injection quantity, reprogramming the car's computer, or adding turbochargers are all prohibited. Converting from a single exhaust to a dual exhaust is not allowed, as it may also change the engine's parameters. No matter how you modify the engine, it should not compromise the vehicle's balance and safety, and modifications must be made within the scope permitted by regulations.

What Do C and H on the Car Dashboard Represent?

On the car dashboard, C and H represent the water temperature. Blue indicates the water temperature is too low, red indicates it is too high, and when unlit, it means the temperature is normal. Under normal conditions, C on the dashboard represents 60 degrees, and H represents 110 degrees. The water temperature gradually increases from C to H. Reasons for high water temperature: Insufficient coolant: A coolant leak can reduce the coolant level, leading to a rise in water temperature. In this case, check for any coolant leaks. If there is a leak, repair the leaking component as soon as possible. If there is no leak, promptly add the appropriate coolant. Faulty cooling fan: A malfunctioning cooling fan can cause the water temperature to rise. When the vehicle is running at high speeds, the generated heat cannot be efficiently transferred to the coolant, affecting heat dissipation and causing the coolant temperature to rise. If this happens, reduce the speed while driving and check if the fan is malfunctioning. Reasons for low water temperature: Thermostat failure: If the thermostat fails and the valve does not close, the coolant will continuously circulate, potentially causing the engine's water temperature to drop too low. Some vehicles may even have the thermostat removed in summer to lower the temperature, which can also result in a very low engine water temperature. Abnormal operation of the radiator fan: If the cooling fan runs continuously due to wiring issues, it will slow down the warming efficiency of the engine and coolant, leading to a slow rise in water temperature and significantly increased fuel consumption.

How to Check if a Car is China 5 or China 6 Emission Standard?

Check the relevant information on the vehicle conformity certificate. The vehicle conformity certificate contains many key details, and it will clearly indicate the emission standard the vehicle complies with. Query through specialized websites. After identifying the model you intend to purchase, you can find the specific Vehicle Identification Number (VIN) in its related documentation. Visit the Motor Vehicle Environmental Protection Website for inquiries. By entering these two numbers, you can access the vehicle's environmental information, including the emission standard it adheres to.

How does the Exhaust Gas Recirculation (EGR) system work?

The working principle of Exhaust Gas Recirculation (EGR) is a specific application of the heat capacity theory. Since triatomic gases such as CO2, H2O, and NO2 in engine exhaust have relatively high specific heat, when fresh air-fuel mixture is mixed with exhaust gas, the heat capacity increases accordingly. Heating this exhaust-diluted mixture requires more heat for each degree of temperature rise. With the total heat released by fuel combustion remaining unchanged, the combustion temperature is thereby reduced. The primary purpose of EGR is to reduce nitrogen oxides (NOx) in the exhaust gas and improve fuel economy under partial load conditions. There are various forms and control methods for EGR systems. Based on the actuator (EGR valve) control mechanism, they can be classified into mechanically controlled EGR systems and electronically controlled EGR systems.

What is the mandatory scrapping period for vehicles?

Vehicles must be mandatorily scrapped upon reaching the prescribed service life. The standards for mandatory scrapping are as follows: Reaching the prescribed service life. After repair and adjustment, still failing to meet the national standards for in-use vehicle safety technical requirements. After repair and adjustment or the adoption of control technology, still failing to meet the national standards for in-use vehicle requirements regarding atmospheric pollutant emissions or noise. Failing to obtain the motor vehicle inspection qualification mark for three consecutive inspection cycles after the expiration of the inspection validity period. Private and commercial vehicles have different scrapping periods: Private vehicle scrapping regulations: For 5-seat family cars and 7-seat SUVs, non-commercial small and mini vehicles have no service life limit. When the normal mileage reaches 600,000 kilometers, the state will guide the scrapping. Apart from the above, small and mini non-commercial passenger vehicles, large non-commercial cars, and wheeled special-purpose machinery vehicles also have no service life limit. Common commercial vehicle scrapping regulations: Small and mini taxi passenger vehicles have a scrapping period of 8 years, medium taxi passenger vehicles 10 years, and large taxi passenger vehicles 12 years. Public transport passenger vehicles have a scrapping period of 13 years, other small and mini commercial passenger vehicles 10 years, and large and medium commercial passenger vehicles 15 years; mini commercial trucks have a scrapping period of 8 years, while light and large commercial trucks have a scrapping period of 10 years.

What Causes Tire Bulges on New Cars?

Reasons for tire bulges on new cars: 1. Impact on the tire, such as suddenly hitting a curb, quickly driving over a speed bump, or running over a large pothole. These actions can cause violent compression of the tire, increasing internal air pressure and causing the weaker sidewall to bulge outward. 2. Poor tire quality, where inferior tire materials can lead to bulging. 3. Harsh road conditions, such as driving at high speeds over gravel, rough hard surfaces, or raised manhole covers, which significantly impact the tires. Encountering road surfaces with severe drops that damage tires and suspension is also a major cause of bulging. 4. Insufficient tire pressure, where even minor bumps or slight road irregularities can cause excessive tire flexing, leading to bulges.
