一种以煤作为燃料的柴油机有希望使结构坚固的标准型热机使用廉价而丰富的燃料。经济性研究表明,即使按中等柴油价格计算,燃煤机车具有理想的投资利润率。为了开发利用大量的煤资源,进一步扩展了煤-水燃料的合成。现已发展到在1(?)00r/min下采用机械和电子式燃料喷射进行燃烧。在整个负荷工况,可以燃用两种燃料,使柴油机正常运行。喷嘴的腐蚀可通过采用金刚石镶套得到控制,活塞环和气缸套的磨损则通过碳化钨涂层得到控制。废气排放测量结果表明,各种微粒和SO_2较高,而NO_x、CO以及HC较低。关于微粒和SO_2偏高的控制措施,目前仍在进行研究。
A diesel-fueled diesel engine has the potential of making a robust, standard heat engine use cheap and abundant fuel. Economic studies show that coal-fired locomotives have an ideal ROI even at medium diesel prices. In order to develop and utilize large amounts of coal resources, coal-water fuels have been further expanded. It has been developed to burn at 1 (?) 00r / min using mechanical and electronic fuel injection. In the entire load conditions, you can burn with two kinds of fuel, the normal operation of the diesel engine. Corrosion of the nozzle can be controlled with diamond inserts, and the wear of the piston rings and cylinder liner is controlled by the tungsten carbide coating. Exhaust emission measurements show that various particles and SO 2 are higher, while NO x, CO and HC are lower. Regarding the control measures of the high particle and SO 2, research is still underway.
