MWM公司新的D234柴油机系列(图1)是由应用范围广、使用可靠性高的D332柴油机系列发展而来的。由于扩大了冲程和缸径,提高了平均有效压力,使发动机在尽量不改变外廓尺寸的情况下最大功率比原机提高63％,从而达到了很有利的比重量、体积功率和燃油耗量。通过对排气道截面、增压系统和燃烧系统的重新设计,以及为承受较高的气缸压力而设计了坚固的曲轴箱和传动机构,从而使功率得以提高。 虽然设计参数不是主要体现在每一机型的重量和体积的小型化上,但由于高质量的设计提高了潜力利用程度,最终还是得到了比重量小和体积功率高等方面的突出指标,由此达到没有更多的其它结构系列能与之在价格/千瓦上竞争。V8发动机的功率范围能够满足至今需要使用V12发动机的功率需求,而这台最大功率为600千瓦的发动机已超过载重车辆发动机结构系列目前的功率范围。
The new D234 Diesel Engine Series from MWM (Figure 1) was developed from the wide range of applications and high reliability of the D332 Diesel Engine Series. Due to the enlarged stroke and cylinder bore, the average effective pressure is increased so that the maximum power of the engine is increased by 63% compared with that of the original machine without changing the size of the outer cylinder, thereby achieving very favorable specific weight, volumetric power and fuel consumption. Power is improved by redesigning exhaust passage sections, pressurization and combustion systems, and designing a robust crankcase and transmission to withstand high cylinder pressures. Although the design parameters are not mainly reflected in the miniaturization of the weight and the volume of each model, due to the high potential of the design, the outstanding utilization of the potential is eventually obtained with outstanding performance in terms of small specific weight and high volume power. As a result, There are no more other series to compete with the price / kW. V8 engine power range to meet the need to use V12 engine power needs so far, and this maximum power of 600 kilowatts of the engine has exceeded the load vehicle engine structure series current power range.
