Abstract

The invention relates to a tester for testing the fuel economical efficiency of a light-weight automobile. Aiming at the problem that an automobile can be only tested on a simulation chassis rotary drum dynamometer because the existing fuel measurer can only measure transient fuel consumption or kilometer fuel consumption, so that the economical efficiency of an actual automobile cannot be testedon a road according to a rule, the invention provides a tester for testing the fuel economical efficiency of the light-weight automobile. The tester mainly comprises a fuel consumption meter, a singlechip, an interface chip, a control panel, a display, an automobile speed sensor, a main flow sensor, an auxiliary flow sensor, forwarding gear sensors, an analog/digital (A/D) converter, a circuit and the like. Fuel consumption can be tested according to a road spectrum diagram of a circulation working condition prestored into the singlechip or a requirement of a constant-speed working condition,so that a real road condition and an actual automobile condition can be reflected, and the current transient fuel consumption, the kilometer fuel consumption and the total stored fuel consumption canbe displayed and output; data cannot be lost in a state of power failure, and the data can be put off and accumulated in a state of power on; and the tester is convenient to mount, safe and reliable,and on-automobile test is convenient.

Description

technical field [0001] The invention relates to a tester for a light vehicle fuel economy experiment. Background technique [0002] At present, for the measurement of vehicle fuel economy, the main on-board records are on-board or the measured vehicle is measured on a chassis dynamometer that simulates working conditions. The existing on-board records cannot perform fuel economy according to national standards. The cycle conditions and the measurement of constant speed fuel consumption, the national standard "Light Vehicle Fuel Consumption Test Method" (GB / T19233-2008) and "Light Vehicle Pollutant Emission Limits and Measurement Methods" (GB / T18352.3-2005 ) stipulates that the fuel economy of cycle conditions mainly includes the fuel consumption per 100 kilometers of the three cycle conditions of UDC, urban suburban condition EUDC, and urban suburban comprehensive condition NEDC, and the loading quality of the car is full or empty ; Constant speed fuel consumption The fuel ...
