发动机的TIMING BELT应该要调整.

"Biodiesel has a higher cetane number than petro which means it ignites more readily. This would seem to indicate that a few degrees of retardation is required to ensure that peak cylinder pressure isn't reached before top dead centre. Also, it's reported that NOx emissions are reduced by retarding the timing.

On the other hand, it's also stated that biodiesel has a longer burn time than petro, so requires advanced timing to keep the burning mixture in the cylinder for longer.
