共轨柴油防爆发动机的开发

Development of Common Rail Diesel Explosion-proof Engine

根据《煤矿安全规程(2016)》第378条规定:井下使用矿用防爆柴油机动力装置,在正常运行条件下尾气排放应当符合有关规定,排放标准达到非道路国Ⅲ及以上。为满足该要求,在本公司现有发动机基础上,公司联合某矿用机械公司开发国内首款高压共轨柴油煤矿用发动机,这款发动机的额定功率为60kW,最大扭矩260N·m,满足《MT220-2006防爆柴油机通用技术条件》设计要求,防爆发动机整机表温低于150℃,防爆后发动机排放达到非道路国Ⅲ要求。

According to Article 378 of the "Coal Mine Safety Regulations(2016)": the use of mine explosion-proof diesel engine power plants in underground mines, under normal operating conditions, the exhaust emissions should meet the relevant regulations, and the emission standards should reach non-road country Ⅲ and above. In order to meet this requirement, based on the company’s existing engine,the company cooperated with a mining machinery company to develop the country’s first high-pressure common rail diesel coal mine engine.This engine has a rated power of 60 KW and a maximum torque of 260 Nm. 2006 Explosion-proof Diesel Engine General Technical Requirements" design requirements, the surface temperature of the explosion-proof engine is lower than 150℃, and the engine emission after explosion-proof meets the requirements of non-road country Ⅲ.
