Isuzu dual-fuel system simplifies fuel changeovers

Isuzu is making it easier for equipment owners to switch fuels from natural gas to liquid propane, letting users switch by merely sending a signal to the engine. Released in October 2019, the dual-fuel 4HV1 engines and power units also have a higher compression ratio that helps conserve fuel.

The alternative fuel engines, designed for non-emergency and emergency standby generator applications and multi-speed applications, let operators switch fuel sources without reconfiguring the base engine. This feature helps to reduce downtime on site, according to Isuzu, which plans to feature the dual-fuel system at ConExpo-Con/Agg in March (South Hall 4, S85406).
