Jacobs employs cylinder deactivation in HD engines to lower CO2, NOx

Combustion engines have experienced a mounting PR problem in recent years, as more truck OEMs, major cities and countries announce their intentions to more aggressively pursue non-diesel vehicles, especially those powered by electric drive. But proponents of the IC engine are not going down without a fight, developing new technologies and employing established solutions in new applications to improve its efficiency. Jacobs Vehicle Systems falls squarely into this camp.

Known for manufacturing heavy-duty diesel engine retarding systems and valve actuation systems, Jacobs revealed at IAA Commercial Vehicles a new cylinder deactivation (CDA) technology that uses the proven componentry of its High Power Density (HPD) engine brake. One, two or three cylinders can be deactivated as needed. CDA and HPD technologies are modular and can be integrated into an engine individually or together.
