Problems solved by technology

The ignition advance angle determined by this method only considers the power of the engine, but does not take into account the emission. When applied to a coke oven gas engine, it will inevitably lead to a serious excess of nitrogen oxide emissions and bring serious pollution to the atmosphere.

Embodiment Construction

[0030] Further illustrate the present invention below in conjunction with accompanying drawing.

[0031] Such as figure 2 Shown, the present invention a kind of method that obtains the optimal ignition advance angle of coke oven gas engine, concrete steps are as follows:

[0032]Step 1: Determine the ignition advance angle range for the coke oven gas engine to run stably (without knocking, and the speed and power fluctuations are within 5%) under different working conditions.

[0033] Such as figure 1 As shown, the coke oven gas engine 1 is modified on the basis of a gasoline engine, and the fuel supply system of the coke oven gas engine 1 includes a coke oven gas tank 2 and a pressure reducing valve 3 . First, the operating conditions of the coke oven gas engine are controlled by the dynamometer 4 (the operating condition parameters are speed and power), and the torque of the coke oven gas engine in each working condition is obtained at the same time; the data acquisition ...

Abstract

The invention discloses a method for obtaining the best advance angle of ignition of a coke-oven gas engine. A common advance angle of ignition optimization method, MBT, fails to take emission performance into account and leads to emission of nitrogen oxides exceeding the standard seriously when applied to the coke-oven gas engine. According to the method, the coke-oven gas engine improved by a gasoline engine is adopted, and with combination of a dynamometer, an emission analyzer and a combustion analyzer, influence rules on engine power performance and emission characteristics by the advanceangle of ignition under different working conditions are researched, algorithm of advance angle of ignition optimization is adopted based on the influence rules to establish a single objective solution model and calculate the best advance angle of ignition under different working conditions. The obtained best advance angle of ignition can be written in ignition MAP of ECU to be used for actual control of the coke-oven gas engine.

Description

technical field [0001] The invention belongs to the technical field of engine engineering and relates to a method for obtaining the optimum ignition advance angle of a coke oven gas engine, which is suitable for the coke oven gas engine. When the engine burns coke oven gas, through this method, the optimal ignition advance angle of the engine under various working conditions can be obtained, and the ignition MAP diagram in the ECU can be recalibrated to make it directly Applied to coke oven gas engine. Background technique [0002] With the rapid development of the automobile industry, its huge energy consumption has threatened the country's energy supply security, and at the same time, a large amount of exhaust gas has also directly threatened the ecological environment and human health. Alternative fuels for clean vehicles have become an important research topic in various countries, among which alcohol fuels and gaseous fuels are the most widely used alternative fuels, b...
