Heavy-duty engines in the 6- to 16-liter displacement range are at the core of our engine research and development activities, resulting in many of the technologies in use today on heavy duty engines. We have been at the forefront of heavy-duty natural gas engine development, including fueling and air-fuel mixing techniques and combustion chamber characteristics that led the industry in the development of production engines. We have performed conversions from compression ignition diesel to spark-ignited natural gas engines on many platforms and are proficient at reaching performance, emissions, and fuel efficiency targets.
