...Weijian Zhou; Hongyuan Xi; Song Zhou; Majed Shreka; Zhao Zhang Due to energy shortage and environmental problems, the application of natural gas in internal combustion engine has attracted extensive attention. Therefore, diesel pilot ignition natural gas engine is a promising technology. However...

... for single zone diesel combustion analysis. The sensitivity was evaluated over the complete operating range of the engine using a combination of experimental and modeling techniques. This provides a holistic understanding of combustion measurement accuracy. For several metrics, it was found...

...Yi Wang; Limin Wu; Shuo Liu; Mei Li; Xianghui Meng; Yi Cui Composite pistons are often used in heavy duty diesel engines due to its good reliability and durability. Owing to the alternating loads, fretting wear usually happens on the mating surfaces between piston crown and skirt. In this paper...

... that the level of agreement now seen is purely coincidental and unintentional as the main goal of this exercise was to investigate the sensitivity of the simulation to chemistry. Rerunning the IQT and diesel simulations with the modified reduced mechanism was also considered. However, both the detailed...

...D. Gould; D. P. Gardiner; M. LaViolette; W. D. Allan This paper describes experimental research aimed at developing an on-board smoke sensor for diesel engines. The sensor element was similar to a conventional spark plug. Electrical heating of the insulator was used to prevent carbon fouling from...
