A newly developed heavy duty diesel engine in dual fuel mode of operation has been studied in detail. The main fuel would be natural gas and diesel oil as pilot injection. The importance and effects of mixture preparation and formation through ports, valves and in cylinder flow field with different swirl ratio and tumble on diesel combustion phenomena is an accepted feature which has been studi...

Abstract New alternative jet fuels have provided many advantages in the aviation industry, especially terms of economics and environment. However, fuel–seal compatibility is one major issues that restricts fuel advancement into market. Thus, to help understand solve problem, this study examines swelling effect prepared non-prepared O-rings different aromatic species. Stress relaxation experimen...

This study investigates the ignition and combustion characteristics of interacting diesel-pilot hydrogen (H 2 ) jets under simulated compression-ignition engine conditions. Two converging single-hole injectors were used to inject H into an optically accessible constant-volume chamber (CVCC). The parameters varied include fuel injection sequence, timing between injections, ambient temperature (7...
