WebApr 1, 2024 · The rail pressure, injection timing and duration of both the direct injected diesel and port injected methanol were controlled through an open engine controller that used a National instrument based on field programmable gate array system. The engine was coupled with a water-cooled eddy current dynamometer for loading. Table 3. WebNov 28, 2008 · The pilot injection serves as the start of combustion, especially at idle speed. If indeed you do disable the pilot injection, be prepared to advance the main injection event to at least the point where the pilot occured, or your engine will not run well at all. And after that you will need to continue to tweak the timing table because the ... haebea website

WebJan 1, 2002 · The results obtained will be used as a basis for comparison with those obtained from studying the effects of pilot fuel injection timing. The engine will be tested using methane or propane as the main fuel, while Diesel fuel is used as the pilot fuel. Three values of injection timings of 25°, 27.5° and 30° BTDC are used in the present test. 4. Webearly pilot injection timing tends to produce intermediate main ignition delay resulting in a complete combustion process due to long residence time for the reaction of fuel-air (Guntram A. Lechner, Timothy J. Jacobs et al. 2005-01-0167, 2005). As a result, the early pilot injection timing produces the higher in-cylinder pressures leading to ...
