I am specifically interested in retrofitting as many of our older engines as possible in order to convert our many Cats to alternative fuels/mixtures through a planned maintenance program. My employer has provided me support in this quest of developing retrofit opportunities. I would appreciate your information for Cat engines are more than half of our sizeable stationary and on/off road fleet., many with few hours on the engine because the business is seasonal (summer) and highly regulated for sound compliance.
My specific concerns include:
Documenting the unit conversion to an appropriate fuel(s) for acceptable engine life
Documenting acceptance by California authorities with an acceptable alternative fuel vehicle status
Measuring methods to support continued status as alternative fuel compliant
Methods of complying with Tier 4 engine requirements: I was advised that merely changing the head on a "new" Cat engine with only 500 hours on it will NOT be an acceptable Tier 4 engine as the block is from 1999 and is assumed defective due to age though the engine is still being sold. Diesel repowering would be well in excess of $10K, and the genset would be an additional engine.
Please respond in the forum as many firms are confronted with compliance.
Thank you for the forum,
