Emission Solutions – other heavy-duty road engines: natural-gas conversions of the ESI series from 255 to 300 hp, throttle body injection, model year 2012
Emission Solutions is a US company that converts heavy-duty diesel engines to natural-gas operation and certifies the results as its own ESI engine families with the Environmental Protection Agency. This page gathers the ESI-series models that the register could not assign to a named engine: ESI0308, ESI0313, ESI0326 and ESI0444, whose engine-family codes point to displacements around 7.3 and 7.6 litres.

The register lists here 4 versions with 255 to 300 hp rated output at 1,999 to 2,400 rpm, all with throttle body injection. The fuel entered is natural gas, the model year is 2012. Maximum torque lies between 650 and 883 lb-ft (881 to 1,197 Nm) at 1,400 to 1,500 rpm.
Natural-gas engines of this power class between 255 and 300 hp with a low rated speed are designed for high torque at the lower end of the rev range, as required by refuse trucks, city buses and other heavy-duty vehicles running stop-and-go duty cycles. Emission Solutions appears here as one of the specialised US converters of natural-gas drivetrains, adapting proven diesel blocks to an alternative fuel.
On a used converted engine, the inspection and test date of the natural-gas tank, the tightness of lines and pressure regulators, and the condition of the ignition system and catalytic converter all matter. Parts for the gas system run through Emission Solutions' distribution, for the base engine block through the respective diesel engine maker.
