Car's 7-speed dual-clutch refers to two sets of manual transmissions, whose working principle is: one transmission manages 1st, 3rd, 5th, and 7th gears, while the other transmission manages 2nd, 4th, and 6th gears, with both automatically alternating their operation. The dual clutch is located between the engine and the transmission, acting as a switch for power transmission from the engine to the transmission. It is a transmission mechanism capable of both transmitting and cutting off power. The function of a car's dual-clutch is to ensure smooth starting of the vehicle, reduce the impact load on the transmission gears during gear shifting, and prevent overload of the transmission system. The components of a car's dual-clutch transmission include: the dual clutch, three-shaft gear transmission, automatic gear shifting mechanism, and electronically controlled hydraulic system.

What fuel is used in hydrogen-powered car engines?

Hydrogen-powered car engines actually come in two types: hydrogen-fueled engines and fuel cell engines. Engines that use pure hydrogen fuel or hydrogen-blended fuel both belong to the hydrogen-fueled engine category. By making corresponding modifications to current gasoline engines, they can be adapted to burn hydrogen, offering strong practicality. Moreover, hydrogen can either premix with air before entering the cylinder or be directly injected into the cylinder to form a combustible mixture. The other type, fuel cell engines, primarily consist of components such as the fuel cell stack, engine controller, hydrogen supply system, and air supply system. Their core lies in the fuel cell engine system, which is crucial for the vehicle's operational safety and significantly impacts whether fuel cell vehicles demonstrate mature and reliable performance. Hydrogen-fueled cars use hydrogen as their primary energy source for propulsion. The greatest advantage of using hydrogen as an energy source is its reaction with oxygen in the air, producing water vapor as exhaust, effectively reducing the air pollution issues caused by traditional gasoline-powered vehicles.

How much fuel is consumed by idling with the heater on for one hour?

Idling with the heater on for one hour consumes approximately 0.6-1L of fuel. Under normal circumstances, using the heater does not increase engine fuel consumption. The heater relies on the engine's heat dissipation system, where a small fan in the engine compartment blows the heat collected by the cooling system into the car. How to use the heater When the coolant temperature gauge reaches the middle position, you can start using the heater. However, it is recommended to first use the external air circulation mode to expel the cold air inside the car, then switch to internal air circulation after 3-5 minutes. Hazards of idling with the heater on: Since the engine is idling, incomplete fuel combustion may produce carbon monoxide. If the windows are closed, the concentration of carbon monoxide inside the car will gradually increase, potentially leading to carbon monoxide poisoning for the occupants. Additionally, this can increase engine carbon buildup.
