Is bi-fuel operation detrimental to the diesel engine?
No. In fact, the cleaner burning characteristics of NG result in less contamination of lubricating oil and reduced engine wear. In addition, peak cylinder pressures and exhaust temperatures are reduced during bi-fuel combustion, which relates to lower engine wear. Bi-fuel engine testing has shown longer operating life along with opportunities for extended service intervals and reduced oil service costs when compared to a standard diesel engine.
