Engine high idle speed problem: how to solve it?Trade compliance training resources When your engine is in a state of high speed when idling, it will bring you a lot of inconvenience and trouble.High idling speed will not only cause the vehicle to vibrate, but also lead to fuel consumption, excessive noise and excessive exhaust emissions, which will affect the safety and economy of driving. Therefore, for the problem of high idling speed of the engine, we should find the cause and solve it as soon as possible to ensure the normal operation of the engine. This article aims to introduce the causes and solutions of high idling speed. I. Multiple reasons for high idling speed 1. Fuel system problems: The fuel system is composed of a fuel pump, a fuel injector, a timer, etc. If any of the parts fails, it may cause unstable operation of the engine, high idling speed and other phenomena. Two. Air filter failure: Air filter is a necessity for engine operation. If there are problems such as blockage or wear, it will affect the oxygen supply of the engine, resulting in insufficient combustion of the engine and high idling speed problems.3. Ignition system problems: The ignition system includes spark plugs, ignition coils and other components. If there is a problem with any of these parts, it will lead to insufficient ignition or early ignition timing, causing high idling speed and other problems. Four. Trottle control system problem: The throttle control system is composed of throttle electronic pedal, throttle butterfly valve, etc. If it fails, it will lead to incorrect oil and gas ratio, resulting in high idling speed and other problems. 5. Engine itself problems: Sometimes there are problems with the engine itself, such as valve, piston, cylinder liner and other failures, which will also lead to high idling speed. II. The solution to high idling speed 1. Check and clean the air filter. If your engine has a high idling speed problem, you should first check and clean the air filter. After long-term use, the air filter will become dirty and fail, unable to filter the air.If you can remove specific dirt, you need to replace it or keep it cleaned regularly after adsorbing it for a period of time. Two. Adjust the ignition system. If the ignition system fails, it can be solved by adjusting the adjustment screw of the ignition system. If the fault is serious, the ignition coil, spark plugs and other parts need to be replaced. 3. Check the throttle control system. If the throttle control system fails, it can be judged by checking the electronic pedal, throttle butterfly valve and other components. If there is a problem, it also needs to be replaced and repaired in time. Four. Cleaning the fuel system. If the fuel system fails, it can be solved by cleaning the fuel system. Before cleaning, you can add some fuel nozzle cleaner to make it deeply cleaned to achieve the effect of thoroughly cleaning the sediment. 5. Replacing or repairing engine parts if none of the above methods can solve the problemFor idling problems, you need to check the problems of the engine itself, such as valve, piston, cylinder liner and other faults. At this time, it is necessary to bring the engine to a professional vehicle repair shop for inspection and maintenance. In short, after checking the engine failure, timely replacement or repair of the problematic parts, and regular cleaning and maintenance of the engine are the most effective ways to solve the high idling problem. When driving a vehicle, pay attention to listening to the sound of the engine, conscious personal and accurate operation related to vehicle maintenance, which can reduce the chance of problems and extend the service life of the vehicle.
