The new car is a very happy to start, but the car followed by the problem, but not so happy, in recent years, many car owners will have such a problem, that is, after the car is used, soon there is engine shake, and the degree of shake is still very serious. At the same time, the "checkengine" fault indicator is on. Why is that? Is it a quality problem?

Many owners of the above phenomenon will suspect that it is because of the manufacturer's quality problems, and will still require the manufacturer to make quality claims, and the manufacturer is of course unwilling to compensate. Then after the identification of the manufacturer, this failure phenomenon of the vehicle, the system itself is not a problem, the real reason is: unclean and unstable fuel caused by the pollution or blockage of the fuel supply system caused by the engine "shaking".

For the above questions, we also asked the experts, the expert's answer is: "In order to protect the natural environment worldwide, most countries, especially developed countries, strictly monitor the exhaust emissions of vehicles produced by automobile manufacturers, and unqualified automobile products are never allowed to be sold on the market." In order to meet emission standards, vehicles produced in European countries after 2001 must be installed with euiv (European No. 4) exhaust emission control system, and vehicles produced in the United States must be equipped with obdii exhaust emission control system, both of which are currently advanced control systems that can detect vehicle exhaust emissions and fuel cleanliness very sensitively. Unclean fuel can lead to contamination of the fuel supply, ignition and emission systems, which can lead to the lighting of the engine fault indicator "checkengine" and varying degrees of engine shake.

At the same time, experts also gave us suggestions: in order to avoid more effective car driving without shaking, it is to continuously add 98 # gasoline or 97 # / 90 # gasoline with stable performance indicators and add quantitative oil circuit cleaners after thoroughly cleaning the contaminated system.

The above solved the problem of why the new car engine will shake, and finally gave advice to solve this problem. I hope the above are helpful to everyone.
