This paper introduced theoretical model of calculating fuel consumption by carbon balance method. The flow measurement module was designed to test the flow of diluted exhaust. Also, gas analyzer was designed to measure the concentration of gas which contain the element of carbon. The exhaust gas dilution ratio could be changed through changing the speed of the electric motor which is regulated by the frequency converter based on opening exhaust dilution sampling technology. The software which could be used to correspond and measure checked data online was developed by VB and C. The experiments showed that the system had a high accuracy, well stabilization and reliability. It is important to evaluate and monitor fuel economy and emission performance on vehicle. INTRODUCTION Nowadays, energy and environmental situation is increasingly serious. Made in China 2025 demands automotive industry to save energy, reduce emission of internal combustion engine and promote the development of automotive industry by means of information. However, when vehicle are tested in the fuel-economy testing of in-use vehicle on the vehicle comprehensive performance testing line, the fuel consumption can be measured by volumetric method and gravimetric method. But the oil duct of the being detected vehicle need to be dismantled with these methods, which could cause a lot of inconvenience to actual operation [1]. Carbon balance method was deemed to solve the problems that had happened in direct measurement at home and abroad. At present, all of the systems which can measure the fuel consumption using the method like constant volume sampling (CVS) in foreign countries. But it has some defect such as huge volume, expensive and so on. Also, it is inconvenience to operate at the check line [2]. In order to solve these problems, this paper introduced an intelligent and rapid test system which was based on exhaust dilution sampling, measuring the concentration of exhaust which contain the element of carbon and theoretical model of calculating fuel consumption by carbon balance method. The system used advanced way that can analyze and measure vehicle exhaust. It can also be used to diagnose and control the fuel consumption in vehicle. It is important to popularize vehicle fuel consumption test at the check line, as well as carrying out relevant rules of law.
