Westport™ 2.4L industrial engines—targeting the liquefied petroleum gas (LPG) and natural gas (NG) industrial markets—are the result of years of planning and development to fully integrate Westport multipoint fuel injection (MPI) technology with Hyundai Motor Company's high quality, durable, advanced 2.4-liter industrial engine platform. The result is a high-performance, low emissions solution that offers advantages over incumbent products, including:
- more compact engine package,
- higher torque and power,
- enhanced acceleration and transient response, and
- quick start-up in all operating conditions.
The Westport MPI fuel system is designed to operate on either LPG or NG. Westport engines comply with 2013 California Air Resources Board Standards (CARB) for off-road large spark-ignited engines, and 2013 U.S Environmental Protection Agency (EPA) regulations for non-road and stationary engines 19 kW and greater.
Westport products use a three-way catalyst to control emission levels. The MPI system provides precise control of fuel injection with more rapid toggling of the fuel/air ratio. This minimizes the required catalyst size and required precious metal loading and provides additional benefits for longterm catalyst life.
