Conversion system meets several criteria, to be attractive to diesel engine owners.
Most importantly the natural gas fuel costs, based on an equivalent energy basis, have traditionally been lower than diesel fuel.
A dual fuel engine has same power characteristics to its base diesel engine and is able to quickly revert to ordinary diesel operation.
This allows to switch back to diesel operation at times when natural gas is temporarily unavailable or not cost effective.
The conversion equipment is robust, relatively non intrusive and can be easily removed, to ensure that the value of the original equipment is maintained and reliability not effected.
The initial capital investment for the conversion is paid back quickly by savings in fuel costs.
