You can start the engine while charging a car battery. When the car is idling, the engine drives the generator, which in turn charges the battery. However, the efficiency of charging the car battery by idling the engine in place is very low. If the battery is severely depleted, it's best to remove the battery and charge it using a charger. Be careful not to start the vehicle rapidly and continuously. If the car fails to start on the first attempt, wait at least 15 seconds before trying again to avoid over-discharging the car battery, which could affect its normal service life.

Will the Car Stall If You Press the Clutch and Brake Together?

Pressing the clutch and brake simultaneously will not cause the car to stall: Disadvantages of pressing the clutch and brake together: This is not good for the vehicle. The correct way to stop the car is when driving at high speed, if not in an emergency, first press the brake to reduce the speed to about 25 km/h, then press the clutch while firmly pressing the brake. Stopping by downshifting: When driving at low speed, press the clutch first and then the brake. In case of emergency braking: If it's an emergency, press the brake directly, using both the braking system and the engine to stop the car. This will indeed cause the car to stall, but in an emergency, safety is more important.

Is Castrol Edge Suitable for Turbocharged Engines?

Castrol Edge is suitable for turbocharged engines. Different vehicle models have varying requirements for oil standards, so it depends on your specific vehicle model. Working Principle of Turbocharging: Gasoline engines rely on the combustion of a combustible mixture of gasoline and air within the cylinders to generate power. The output power and torque of an electronically fuel-injected gasoline engine depend on the amount of air entering the cylinders. When the engine's performance is already at its optimal state, the only way to increase output power is by compressing more air into the cylinders to enhance the combustible mixture, thereby improving combustion efficiency and increasing output power. Structure of a Turbocharger: The turbocharging system in gasoline engines consists of two main components: the turbocharger and the intercooler. The turbocharger compresses the air, and the intercooler cools the compressed air. The turbocharger itself is composed of a turbine housing and a compressor. The intake port of the turbine housing is connected to the exhaust manifold, and the exhaust port is connected to the exhaust pipe.

What kind of batteries are used in electric vehicles?

Currently, the vast majority of electric vehicles are equipped with lead-acid batteries due to their low cost and high cost-effectiveness. The role of lead-acid batteries: Lead-acid batteries are a type of battery that can store limited electrical energy. Their working principle involves converting chemical energy into electrical energy. They use lead plates filled with sponge-like lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and a 22-28% dilute sulfuric acid solution as the electrolyte. During battery operation: During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When discharging, metallic lead serves as the negative electrode, undergoing an oxidation reaction and being oxidized into lead sulfate.

Will the car pull to one side if the front tires are one new and one old?

Will the car pull to one side if the front tires are one new and one old? The reason is that the new tire has higher air pressure, while the old tire is slightly more worn, resulting in different grip levels between the left and right tires. The causes of vehicle pulling to one side are as follows: Different tire tread patterns: The tread patterns on the two sides are different, or one side is deeper while the other is shallower. It is best to use the same model of tires for the entire vehicle. At the very least, the two tires on the front axle and the two on the rear axle must be the same, and the tread depth must be identical. If they exceed the wear limit, they must be replaced. Unequal tire pressure on both sides: Unequal tire pressure will cause the tires to become different in size, inevitably leading to pulling to one side when rolling. Uneven spring deformation of the front shock absorbers: The condition of the shock absorber springs can be judged by pressing or comparing after disassembly.

Can Vehicle Inspection Be Done on Saturdays and Sundays?

Vehicle inspection cannot be done on Saturdays and Sundays as the vehicle management office is closed. The office hours are from Monday to Friday, 8:30 AM to 11:30 AM and 1:30 PM to 5:00 PM. Vehicle Inspection Schedule: For passenger transport vehicles, inspection is required once a year within the first 5 years; every 6 months after 5 years. For cargo vehicles and large or medium-sized non-passenger transport vehicles, inspection is required once a year within the first 10 years; every 6 months after 10 years. For small and mini non-passenger transport vehicles, inspection is required once every 2 years within the first 6 years; once a year after 6 years; every 6 months after 15 years. Documents Required for Annual Inspection: Before the annual inspection, check the validity date of the compulsory traffic insurance that includes the vehicle and vessel tax. Bring the ID card of the vehicle owner or the agent, and the vehicle registration certificate.
