Simple fuel consumption test device for passenger car and working method thereof

Abstract

The invention discloses a simple fuel consumption test device for a passenger car, which includes a clamping mechanism and a detection mechanism. The clamping mechanism is internally clamped with a detection mechanism. The clamping mechanism includes a mounting seat, a slide seat, and a connection socket. First fixing seats are installed on both sides above the seat. The housing of the detection mechanism is placed between the clamping seats on both sides, an exhaust pipe connection seat of a suitable connection size installed on the other end of a connection pipe is picked out to be connectedwith a passenger car exhaust pipe, a connection plug of a corresponding connection pipe is adjusted at the same time, a corresponding third air pressure rod on the connection plate extends to drive the connection socket on the fixing plate to move to be in matched connection with the connection plug, selection of a different exhaust pipe connection seat based on an exhaust pipe of a different caris facilitated, matched use with a passenger car with a different type is facilitated, accurate subsequent measurement is ensured through a pipeline and a check valve, the measurement error is reduced, the whole fuel consumption test device is simple and convenient to operate, and the actual measured fuel consumption value can be ensured to be accurate.

Description

technical field [0001] The invention relates to the field of passenger car fuel consumption testing equipment, in particular to a simple passenger car fuel consumption testing device and a working method thereof. Background technique [0002] The measurement of fuel consumption is the main index to evaluate the fuel economy of automobiles. The gasoline engine fuel supply system has developed from the past carburetor type, mechanical injection (K), electromechanical injection (KE) to electronically controlled injection (JET). It is very different. The fuel supply system of diesel engine has also been improved, and great changes have taken place. We should select the corresponding measuring instruments according to the characteristics of the engine fuel supply system, and connect and use them correctly in order to accurately measure the fuel consumption of passenger cars. Fuel consumption. [0003] The existing passenger car fuel consumption testing device obtains the specifi...

Problems solved by technology

[0004] The purpose of the present invention is to provide a simple fuel consumption test device for passenger cars and its working method. In order to overcome the above-mentioned existing fuel consumption test device for passenger cars, the specific fuel consumption can be obtained by measuring the mileage of the passenger car during operation and the reduction of the fuel tank in the fuel tank. The more complicated thing is how to measure the fuel volume in the fuel tank of the car, which cannot be obtained by simple devices. It needs to be obtained by adding detection equipment in the fuel tank. The entire detection process is complicated and the test device is complicated; When testing fuel consumption, the test device needs to be installed on the bus as a whole, that is, the test device needs to be protected and installed. The existing test device cannot realize the technical problem of this function
