WebJan 20, 2012 · The pilot injection timing is set by B0926, B0927, B0928, and B0929. The pilot injection timing is added to the main injection timing. Example: If B0910 is being used and the timing is 20 while chart B0929 is being used and that timing is 13, the pilot injection will turn on at 43 degrees and the main will turn on at 20 degrees. WebOct 28, 2013 · But pilot injection (timing and amount) effects the ignition delay and burn rate, which in turn effects rattle, mpgs, and emissions output. It is well worth looking into and should be changed along with main timing. Also, pilot injection events should always be referenced Before Main Injection Pulse. It's timing should remain consistent ...
Web01:30. When we're talking about diesel injection timing we're going to be referencing the point when the injection first starts, which is referred to as SOI or start of injection. 01:42. In general terms for the main fuel injection event, this is likely to be in the vicinity of perhaps 10 to 15 degrees before TDC. WebWhat is pilot injection timing?
