Abstract

The invention discloses an explosive environment-used explosion-proof diesel engine detection platform and an explosion-proof diesel engine development method, which belong to the field of power machinery. The detection platform comprises an in-cylinder measurement and control system for acquiring combustion-related parameters of the cylinder of the diesel engine, a conventional measurement and control system for measuring conventional parameters of the diesel engine and an exhaust emission testing system for acquiring the exhaust gas of the diesel engine, wherein the in-cylinder measurement and control system comprises a sensor for acquiring in-cylinder combustion parameters and a combustion analyzer connected with the sensor; and the conventional measurement and control system comprisesa dynamometer connected with an engine and a measuring and controlling instrument connected with the dynamometer. The development method comprises steps: the combustion-related parameters of the cylinder of the diesel engine are acquired; the conventional parameters of the diesel engine and the exhaust gas of the diesel engine are measured; when exhaust emission does not reach non-road stage-III emission regulations, all acquired parameters are compared with an original engine, the explosion-proof diesel engine is improved according to a comparison result until the exhaust emission reaches thenon-road stage-III emission regulations, and then, the development is ended.

Description

technical field [0001] The invention relates to the field of power machinery, in particular to a method for developing an explosion-proof diesel engine. Background technique [0002] The emission standard for explosion-proof diesel engines enforced by the state "MT220-90 Inspection Specification for Carbon Monoxide and Nitrogen Oxides in Exhaust Exhaust of Explosion-proof Diesel Machinery Used in Coal Mine" was promulgated and implemented by the Ministry of Energy of the People's Republic of China on November 1, 1990. The requirements for emission country II in this standard have lagged behind the foreign Euro IV standards. In the future, with the urgent requirements of environmental protection requirements, this standard will definitely be improved accordingly. Existing mechanical controllers used in explosion-proof diesel engines for explosive environments have no room for improvement, and it is necessary to develop electronically-controlled diesel engines for explosion-pr...
