摘要
根据改装的双燃料发动机特点设计了基于当量燃料的油气控制策略,该控制策略通过柴油天然气双闭环实现两种燃料的合理控制,并在改装成双燃料发动机的潍柴X6170上进行试验。试验表明,在不改变原柴油机主要结构下,改装双燃料发动机能够替代原柴油机作为船舶动力,燃油消耗降低且排放相应减少,能够平稳进行油气切换,替代率过大时对HC排放及排气温度影响较大。
A governing strategy for dual fuel engines retrofitted from diesel engines was developed based on fuel equivalent. The strategy adopted two closed loops to control the switching of two fuels, and it was tested on a dual fuel engine retrofitted from an X6170 marine diesel engine. The test results show that without changing the main structure of the base engine, the developed strategy enables the retrofitted diesel- gas dual fuel engine to replace the original one with lower fuel consumption and lower emissions, and with a smooth switching of two fuels. But HC emission and the exhaust temperature are much impacted when the gas content is too high.
