Optimizing On Ignition Of Engine For Zhonghua's Car

As we continued to deepen reform and opening-up, people's living standards further improved. The car has not been a luxury thing and become part of people's lives. Moreover, China's automobile industry have been the development and expansion of production has been the second largest in the world, and continue to grow at a rate higher.In our vehicle production ,on the one hand, developed countries such as Europe ,the United States and Japan, multinational joint venture plant in the country, as Volkwagen, Ford, Mercedes, BMW, Honda, Toyota and so on, is still in a strong position; on the other hand ,Our own-brand cars to Chery, Geely and Brilliance Auto, is gradually growing, in the low-end and middling-end car market has been a firm footing ,But in the high-end market is also very vulnerable.This paper mainly on the car of Brilliance Auto market in the ignition system issues a comprehensive tracking, after extensive investigation and analysis of large cars, the spark plug erosion problems improvement measures, and through several rounds of test verification, and ultimately can be resolved. Completed the major work:1, presented an overview of automotive ignition system, namely the development of the ignition system, ignition system components and now several practical aspects such as the ignition system, and explains;2, the modern automobile ignition system's main components, including the ignition coil, spark plugs, high voltage-canble and distributor were introduced;3, 4 G63 with the car of Brilliance Auto on the basic parameters of the engine and its technical characteristics; 4, The car of Brilliance Auto use Maruili electronic control system, the ignition system on this line, high-voltage static output of the ignition coil ,spark plugs and high voltage-canble, as well as the technical characteristics and technical characteristics were analyzed and discussed;5, Spark plugs used the car of Brilliance Auto ablation investigation and analysis;1) Spark Plug ablation and the specific phenomenon;2) the failure of Investigation and Analysis.6, High voltage-canble used the car of Brilliance Auto investigation and analysis;1) Fault Detection and analysis;2) High voltage-canble and spark plug connections and the total resistance measurement;3) Failure Analysis7, the Chinese car ignition energy survey and analysis, the initial ignition of the main current, secondary ignition voltage measurement, and by comparing the analysis of the ignition coil;1) M & M junior ignition of the current measurement and analysis;2) SAME companies on the ignition coil of a secondary voltage measurement and analysis;3) ignition coil of comprehensive analysis and conclusions.8, ignition system improvement and optimization of the measures proposed and implemented;1) Analysis of the overall ignition system;2) the ignition system improvement measures put forward and its implementation.9, improved ignition system after engine test bed;10, ignition system improved after the small group of test equipment and tracking;11, and the eventual confirmation of the programme of work concluded.In the above process, we visited the Beijing Institute of steam and Beijing Polytechnic University in the domestic authority, for consultation on related issues, and the experts have the strong support and selfless assistance. At the same time have also been a number of collaborative show of support units, including test equipment and electronic control systems and related components technical support. In our concerted efforts, through two years and nine months time, and ultimately successful completion of the mandate.
