Embodiment Construction

[0020] The present invention is described in further detail below in conjunction with accompanying drawing:

[0021] With reference to Fig. 1-3, the automobile mass emission of the present invention and fuel consumption measuring device, by intake manifold pressure sensor, intake manifold temperature sensor, five-gas waste gas analyzer, engine speed sensor and single-board computer, with two-in-one A notebook computer with a serial port card. The intake manifold pressure sensor 1 and the intake manifold temperature sensor 2 are installed on the intake manifold of the engine. The engine speed sensor 3 calculates the engine speed by measuring the number of ignition pulses on the high-voltage line of the engine. The five-gas exhaust gas analyzer The sampling probe 4 is installed in the exhaust pipe, and the output terminal of the five-gas exhaust gas analyzer is connected to the RS232 serial port card of the notebook computer. The computer sends control signals to the five-gas ex...

Abstract

The invention relates to a measure method of gasoline engine Release and oil exhaustion, especially, it relates to an automobile oil exhaustion measure device of portable type quickly test the automobile oil exhaustion and quality discharge and software program. It is aimed at applying for carryover of vehicle, and it is good to examining quickly, real-time, non-disorganization. What is called the intake manifold pressure sensor (1), intake manifold temperature sensor(2)install on the engine intake manifold(A), output end of the two connect with the head end of mono-plate processor, the signal output of mono-plate processor connect with the RS232 in series gob block of notebook PC, the engine revolution speed transducer(3)clamping on the engine first jar firing high voltage wire, the sampling probe of five gas exhaustion-gas analyzer(4)insert into the exhaustion tube(C), the output end of five gas exhaustion-gas analyzer connect with the RS232 in series gob block of notebook PC. Via installed test compute model, it could obtain the oil exhaustion of engine and quality discharge rate of each Release contaminant.

Description

technical field [0001] The invention relates to a gasoline engine emission and fuel consumption measurement device, in particular to a vehicle fuel consumption measurement device and its software program which can be portable and quickly measure the fuel consumption and mass emission of the vehicle. Background technique [0002] The existing fuel consumption measurement methods can be classified into two categories: the first category is the direct measurement method, that is, the fuel consumption can be directly measured by disassembling the oil circuit of the automobile engine and connected to the flow measuring instrument. Specifically, it can be divided into volumetric method and gravimetric method. Two kinds. The common features of these two methods are: high measurement accuracy; complex operation, time-consuming, and damage to the original structure of the vehicle. [0003] The second type is the indirect measurement method, commonly used is the carbon balance method...
