BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. Total cost of implementation is much less than $10/1%, he said. Source: Borgwarner.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

Due to the continued exposure of millions of Americans to poor air quality, both the United States Environmental Protection Agency (EPA) and California Air Resources Board (CARB) have announced rulemakings focused on revising the heavy-duty truck emission standards, with a particular focus on tighter limits for oxides of nitrogen (NO x ).

This common core also provides greater confidence in the robustness of prototypes, while minimizing the cost of variants further supports the development of 48V systems. SR machines are ideally suited to this concept of low cost development, while reducing the cost of production components. —Nick Pascoe.
