The invention discloses an automobile fuel consumption detection system and a detection method thereof, relates to the technical field of automobile detection, and solves the technical problems that the prior displacement type automobile fuel consumption detection method has complex operation and long detection period, the prior constant volume sampling fuel consumption detection device for a carbon balance method has high cost and other carbon balance fuel consumption detection devices have low precision. The automobile fuel consumption detection system comprises a main control module, a carbon-containing gas quality measurement system and a chassis dynamometer system, wherein the main control module is a singlechip; the chassis dynamometer system is used for carrying out loading control for an automobile and measuring the rotating speed of wheels after the automobile is started; and the main control module is used for controlling the measurement of the carbon-containing gas quality measurement system, adjusting the concentration and flow of various gases in the dilute exhaust gases of the automobile, and carrying out fuel consumption calculation according to the flow of the adjusted dilute exhaust gases, the concentration of the carbon-containing gas in the dilute exhaust gases and the rotating speed of the wheels. The system and the method are applied to detecting automobile fuel consumption.
Description
technical field [0001] The invention relates to the technical field of automobile detection, in particular to an automobile fuel consumption detection system and a detection method thereof. Background technique [0002] At present, the method of disassembling the oil pipe and connecting the oil consumption meter in series is mostly used for automobile fuel consumption detection. This method is complicated to operate and takes a long time to detect. Due to the need to disassemble and assemble the engine oil pipe, sometimes it will cause damage to the oil circuit. [0003] Another method of automobile fuel consumption detection is the carbon balance fuel consumption detection method, which has been carried out at home and abroad. It measures the quality of carbon elements in carbon monoxide, carbon dioxide, and hydrocarbons in automobile exhaust, and according to the carbon elements before and after gasoline combustion Conservation of mass to calculate vehicle fuel consumption...
