Is It Normal for a Car Not to Generate Electricity at Idle but to Generate When Accelerating?

It is normal for a car not to generate electricity at idle but to generate when accelerating. Below are the specific details about the car alternator: Working Principle: When the external circuit supplies current to the excitation winding through the brushes, a magnetic field is generated, magnetizing the armature into N and S poles. Maintenance: Regularly clean the accumulated dirt and dust on the alternator's surface to maintain cleanliness and ensure good ventilation. Periodically check the tightness of all fasteners related to the alternator and promptly tighten any loose screws. Function: The car alternator is the primary power source of the vehicle. Its role is to supply power to all electrical devices (except the starter) when the engine is running normally and to recharge the battery.

Can Manual Transmission Skip a Gear When Downshifting?

Manual transmission can skip a gear when downshifting. This is particularly necessary when driving on slippery surfaces such as snow, ice, or mud, when the vehicle's driving resistance increases, or in the event of brake failure. Skipping a gear helps reduce speed, prevent the vehicle from skidding sideways, and ensure the safety of the driver and passengers. Skipping a Gear When Downshifting: Skipping a gear means the driver does not downshift in the normal sequence (e.g., 5-4-3-2-1) but instead skips one gear, such as shifting directly from 5th to 3rd or 4th to 2nd. Effects of Skipping a Gear in Manual Transmission: It can increase fuel consumption and oil usage, lead to more carbon buildup, and cause unstable engine idling, all of which have a very negative impact on the vehicle.

Where is the car oil pump located?

The oil pump is divided into a fuel pump and an engine oil pump. The fuel pump is installed in the fuel tank, while the engine oil pump is located inside the engine. Below is relevant information: Wet fuel pump: Currently, the fuel pump in most vehicle models is installed inside the car's fuel tank and is electrically driven. The fuel pump consists of three parts: the pump body, the permanent magnet motor, and the housing. When the permanent magnet motor is powered, it drives the pump body to rotate, sucking fuel from the inlet, flowing through the internal electric fuel pump, and then pressing it out from the outlet to supply the fuel system. The fuel flowing through the internal electric fuel pump cools the armature of the permanent magnet motor, hence it is also called a wet fuel pump. The role of the oil pump in the lubrication system: The function of the oil pump is to raise the engine oil to a certain pressure and then forcibly deliver it to the moving surfaces of the engine components.

What is the reason why the MG6 won't start and displays a steering wheel failure?

When the MG6 won't start and displays a steering wheel failure, it indicates an issue with the electric power steering system, which requires prompt inspection or repair at a service center. The reasons why a car won't start are as follows: Incorrect gear position: For automatic transmission models, the vehicle won't start if the gear is not in the P (Park) position. Therefore, it's necessary to check if the gear is set to P before attempting to start the car. Battery depletion: A depleted battery is a common reason for failure to start. Normally, the battery voltage must be above 12.4V to successfully start the engine. If the battery is severely depleted, it must either be replaced or jump-started. Starter motor damage: The starter motor is responsible for rotating the engine's flywheel to start the engine. If it malfunctions, the engine will show no response when attempting to start.
