With the rapid development of the automotive industry, automobile industry has not only become a pillar industry of China's national economy, but also the lives of people has brought great convenience. At the same time increasing the technological content of vehicles, can quickly resolve the endless technical problems, are increasingly taken seriously, and this is reflected steady development of the automotive industry is one of the important performance. In the low temperature, cold start failure frequently difficult, as the current widespread use of electronically controlled engine, the electronic control system makes the engine more complex the structure, making diagnosis more difficult.Guer solve difficult cold start the engine electronic control failure has become urgent problems.The issue of information and failure by careful inspection of vehicles, to the electronic engine cold start problems and solutions for the formation of fault and an analysis of why. Too much coke is the main cause cold start problems, this paper will focus on carbon deposition, from simple to profound, step by step analysis. On the one hand because of domestic fuel quality, air quality and congestion of traffic to make cars easier to form coke; on the other hand through the daily protection, maintenance of measures to reduce the accumulation of coke, thereby reducing cold start problems from happening.

The issue of information and failure by careful inspection of vehicles, to the electronic engine cold start problems and solutions for the formation of fault and an analysis of why. Too much coke is the main cause cold start problems, this paper will focus on carbon deposition, from simple to profound, step by step analysis. On the one hand because of domestic fuel quality, air quality and congestion of traffic to make cars easier to form coke; on the other hand through the daily protection, maintenance of measures to reduce the accumulation of coke, thereby reducing cold start problems from happening.
