Embodiment Construction

[0019] Such as figure 1 As shown, the system for testing the actual work performance of ignition engine fuel in the present invention includes an ignition engine 1 and a quantitative sampling module 2 connected thereto, an AC dynamometer module 3 and an operation control module 4. The ignition engine device has The fuel to be tested with a specified capacity is added for combustion. The ignition engine has specified specifications (such as engine form, bore, displacement, and compression ratio data), and its operating conditions (speed control, intake air temperature, intake air humidity, etc.) , ignition advance angle, lubricating oil temperature and pressure, etc.) are also in the specified state. The fuel to be tested is added to the ignition engine through the quantitative sampling module according to the prescribed flow rate and pressure law, so that the ignition engine runs and outputs work. Then, through the AC dynamometer module, the work parameters and other relevant...

Abstract

The invention discloses a system and a method for testing actual acting performances of spark ignition engine fuels. The system comprises a spark ignition engine, and a quantitative sample feeding module, an alternating-current power testing module and an operation control unit module connected with the spark ignition engine; fuels to be tested with a stated volume is fed in the spark ignition engine for combustion; the spark ignition engine has stated specification parameters; and the operation working conditions of the spark ignition engine are also located in a stated state. The system can realize precise performance index comparison among different fuels to be tested through transfer of comparison parameters of pure component standard fuels.

Description

technical field [0001] The invention relates to a system and a method for an ignition engine fuel, in particular to a method and an instrument for testing the actual work performance of an ignition engine fuel. Background technique [0002] With the diversification of fuels, especially traditional gasoline fuels have also undergone great changes, such as methanol gasoline, ethanol gasoline, bio-gasoline and various blended gasolines, and the differences between various gasoline components are also increasing . We have an indicator for evaluating vehicle fuel consumption—combined fuel consumption per 100 kilometers, but people often find that they obviously feel that the fuel consumption of gasoline of the same grade from different manufacturers is significantly different under similar driving conditions during daily driving. In other words, we have no evaluation index for the actual work performance of gasoline itself. [0003] At present, in order to grasp the difference ...
