If the engine shakes at idle but runs fine when driving, then it is not a misfiring cylinder. If the engine shakes at idle, it may be due to a damaged throttle body or some sensors. If the engine has a misfiring cylinder, then one cylinder is not working whether at idle or while driving. Misfiring cylinders are mostly caused by faults in the ignition system. Introduction to the automotive engine ignition system: 1. The automotive engine ignition system mainly consists of an ignition coil and spark plugs. 2. Spark plugs are wearable parts that require regular replacement. If spark plugs are used for a long time, the electrode gap will widen, which can affect the spark plug's ignition. 3. Prolonged use of spark plugs can lead to carbon buildup on the electrodes, which also affects the spark plug's ignition.

What is the Driver's Head and Neck Protection System?

The Driver's Head and Neck Protection System, abbreviated as WHIPS, is a passive safety device in automobiles, typically installed in the front seats. Below is a detailed introduction: 1. Overview: Currently, many people suffer cervical spine injuries or even lose their lives due to rear-end collisions, prompting designers to pay attention to head and neck protection systems. Considering the safety of the human cervical spine in accidents primarily involving rear-end collisions, the head and neck protection system was developed, and more and more automobile manufacturers are focusing on its research and development. 2. Working Principle: WHIPS is generally installed in the front seats. When the car is hit from the rear, the head and neck protection system quickly inflates, and the entire backrest tilts backward along with the occupant. The occupant's entire back and the backrest are securely pressed together, while the backrest tilts to minimize the force of the head being thrown forward. The seat back and headrest move backward horizontally, providing gentle and balanced support and protection for the upper body and head, reducing the impact on the spine and neck, and preventing injuries caused by the head being thrown backward.
