Cummins progressing with lightweight downsized T2B2 diesel for pickup; 40% improvement in fuel economy over gasoline V8

Green Car Congress

Cost of the new engine relative to gasoline baseline. The technical focus over the last year has been on new engine installation and performance assessments. In 2013, the Cummins-led team demonstrated a Tier 2 Bin 5 version of the engine on the dyno, and then on a vehicle, while development of the Tier 2 Bin 2 engine started.

Bosch leading Direct4Gas consortium to develop direct injection for monovalent natural gas engines

Green Car Congress

Bosch is leading a consortium in a German government-funded project to develop a direct injection system for monovalent natural gas engines—i.e., engines that run exclusively on CNG. Today’s CNG vehicles are generally bivalent, running on gasoline and CNG with engines designed for gasoline direct injection.
