Repair

An engine with a malfunctioning or damaged component should be repaired quickly to avoid additional damage to the engine, vehicle and emission control system.

Rebuild

Diesel engines often can be rebuilt and continue to operate in the same capacity. An engine in need of rebuilding may have low power, increased emissions and increased fuel consumption. In some cases an engine can be rebuilt to comply with cleaner emission standards.

Repower

Replacing an older engine with a new one which has been certified to cleaner emission standards is another option for some equipment and vehicles. Repowering with a new engine may extended the life of the machine, reduce fuel consumption, and significantly reduce emissions.

Refuel

A variety of alternative fuels can be used in diesel engines. Some require little or no modification to the engine while others require engine conversion or replacement. Some of the alternative fuels include emulsified diesel, biodiesel, natural gas, propane and ethanol. In addition to these fuels, use of diesel fuel with lower sulfur content can help to reduce emissions.

Replace

Replacement involves retiring higher polluting equipment from service before it would otherwise be retired. Newer equipment that meets more stringent emission standards is purchased to replace the retire equipment, sometimes in conjunction with retrofit devices or alternative fuels.
