Mini Van Acceleration And Economic Performance Research

With the erergy shortage, each country constituted legislation pushenergy saving. Our country has constituted legislation——《GB 19578-2004 mpvfuel consumption limit》, this law restricted vehicle manufacturer, as the result, more vehicle manufacturer must pay more attention to it. Max speed ,max climing ,acceleration. The energy shortage has brought the price increasing, and make the consumer pay more attention to the lever of consumption, the law of the fuel economic made the manufacturer think much of the economical efficiency. The fuel consumption of each kilometer less ,the cost lower ,it woulb be welcome. Therefore, each vehicle manufacturer tried themselves to assure the vehicle power efficiency and economical efficiency.For the limit of the condition ,Dong'an company can't adopt more advanced technology. Under the least change ,the better way is to use the present condition to make the more effect. The product of ,Dong'an company hasn't add up to the ideal valve, at present ,the most effective way is to change each shift ratio of transmission system. Any other way can't satisfy the target valve.Through the analysis of the the vehicle power efficiency and economical efficiency, we knew the present condition. Based on it ,adjusted the combination of parameter to calculate the fuel consumption ,climbing ,acceleration. On the basis of instruct opinion ,after the testing ,changing the final gear ratio ,and made the fuel consumption satisfy the demand of the law that what the nation country constituted,and made the remarkable effect.
