Starting with a heavy throttle on a dual-clutch transmission can cause certain damage to the vehicle. It is not recommended to accelerate or decelerate abruptly during driving. Definition of Dual-Clutch Transmission: A Dual-Clutch Transmission (DCT) differs from conventional automatic transmission systems. Based on a manual transmission yet belonging to the automatic transmission category, it not only offers the flexibility of a manual transmission and the comfort of an automatic transmission but also provides uninterrupted power output. Advantages of Dual-Clutch Transmission: The gear shifting time of a dual-clutch transmission is extremely short, even faster than that of a manual transmission, taking less than 0.2 seconds. By eliminating torque interruption, the dual-clutch transmission ensures that the engine's power is continuously utilized and always operates at its optimal level, leading to significant fuel savings. Compared to traditional planetary gear automatic transmissions, it is more conducive to improving fuel economy, with fuel consumption reduced by approximately 15%.

What is an Extended-Range Electric Vehicle?

An Extended-Range Electric Vehicle (EREV) refers to an electric vehicle that, based on a pure electric vehicle, adds an internal combustion engine to charge the power battery or directly drive the motor to extend the driving range, thereby overcoming the short driving range of pure electric vehicles. Advantages of Extended-Range Electric Vehicles: The advantages of extended-range electric vehicles include being eligible for green license plates, providing a good power experience at medium and low speeds, relatively lower fuel consumption compared to conventional fuel vehicles, and no range anxiety. Disadvantages of Extended-Range Electric Vehicles: The disadvantages lie in the inequality between charging efficiency and power output demand. Currently, the maximum speed of high-voltage DC fast charging is 80 kWh, while the power generation efficiency of the range extender usually does not exceed 40 kWh, with most staying within 30 kWh. However, the energy required for initial acceleration often exceeds 30 kWh, and during high-speed overtaking, even 80 kWh may not be sufficient.

What are the disadvantages of range-extended electric vehicles?

1. Power wastage. Since the engine and generator do not directly drive the wheels, this part of the power is wasted, while the weight brought by the engine and generator is not reduced. For example: a range-extended plug-in hybrid vehicle has an engine power of 50KW, a generator power of 50KW, and a motor power of 100KW. The vehicle carries a total power of 200KW from the engine and motor, but the power that can drive the wheels is only 100KW. 2. Higher fuel consumption under highway conditions. This is because under highway conditions, if the engine directly drives the wheels, it can always operate in the optimal working mode. However, the range-extended plug-in hybrid has an additional conversion process, and the conversion itself consumes energy, resulting in higher fuel consumption.

Are private cars prohibited from driving on highways at night?

Private cars are not prohibited from driving on highways at night. Here is the relevant information about cars on highways: Precautions for driving on highways: Do not drive on highways when unfamiliar with the route, do not drive at low speeds, do not drive parallel to large trucks, do not drive between two large vehicles, do not follow behind large trucks or be followed by them, do not occupy the overtaking lane for extended periods, do not stop or reverse on highways arbitrarily. Regulations for cars on highways: Cars with speeds above 70 km/h are allowed on highways. In real life, various provinces have established specific regulations and measures based on the actual conditions of their highways. For example, some provinces allow motorcycles on highways, while others do not.

How to Replace a Lost Electronic ETC?

Bring the original and a copy of your ID card to the bank branch counter to apply for a change, replacement, or reissuance of the card. Bring the original and a copy of your ID card to the bank branch to fill out an ETC service application form, apply for the suspension of the ETC function, which will take effect within 24 hours from the time of acceptance. After receiving the new card, go to the designated bank branch to activate the ETC function. After receiving the new card, call the bank's credit card customer service hotline to activate the card, and the ETC function will be automatically available within 5 working days.

Is Tire Pressure Warning Better or Tire Pressure Display Better?

Tire pressure display is better because it allows for a direct view of the tire pressure. The following are the impacts of both over-inflation and under-inflation: Impact of Over-inflation: Over-inflation increases the friction between the tire and the ground, reducing tire adhesion; it affects the vehicle's braking efficiency and driving comfort; it accelerates wear on the central tread of the tire, shortening its lifespan. Impact of Under-inflation: Under-inflation increases the contact area between the tire and the ground, making the tire prone to overheating; it causes the tire body to expand, leading to cracks on the inner and outer sides; it accelerates rubber aging and increases tire wear.

How to install the timing chain for Chery 4G16?

There are two arrows on the chain cover, located at the crankshaft sprocket and camshaft sprocket positions respectively. There will be small dot marks on the edges of both sprockets. The crankshaft sprocket has one dot, while the camshaft sprocket has two dots. Align these with the arrows for successful installation. Here are some extended details: Timing chain alignment: Align the chrome-plated link with the timing mark on the balance shaft drive sprocket of the crankshaft. After alignment, the chrome-plated link should be approximately at the 6 o'clock position. Place the timing chain on the water pump drive sprocket and adjust the last chrome-plated link to align with the timing mark on the exhaust-side balance shaft drive sprocket. The timing chain has significant transmission resistance.
