Abnormal noises during car ignition may be due to a dead battery, empty fuel tank, or incorrect gear position. Below is relevant information about the car ignition system: 1. Definition of the car ignition system: It is designed for spark-ignition engines to function properly by supplying the spark plugs with sufficiently high-voltage electricity (approximately 15,000 to 30,000V) in the correct firing order for each cylinder, ensuring a strong spark to ignite the combustible mixture. 2. Classification of car ignition systems: (1) Conventional ignition system: The mechanical ignition system operates by the crankshaft driving the distributor shaft rotation, where the cam on the distributor shaft opens and closes the primary contacts of the ignition coil to generate high voltage. (2) Electronic ignition system.

What is the shape of an engine mount pad?

The engine mount pad is a crucial component that connects the engine to the vehicle body. It is shaped like a top and primarily serves to install the engine onto the frame, isolating vibrations generated during engine operation to mitigate their effects. It is also known as "engine mount rubber" or "engine mount cushion." The main function of the engine mount rubber is to prevent vibrations, ensuring that engine noise is not transmitted into the cabin. Symptoms of a faulty engine mount pad include: 1. Steering wheel vibration: noticeable shaking of the steering wheel during engine idle. 2. Seat vibration: distinct vibrations felt when sitting in the seat. 3. Unstable operation: the engine runs unevenly, with no fluctuation in RPM but noticeable engine shaking. 4. Abnormal noises: unusual sounds occur during rapid acceleration or deceleration. 5. Chassis noises: abnormal sounds emanate from the chassis during vehicle startup and braking.
