Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. However, this setup adds complexity and cost. [In

DOE FY17 SBIR Phase I Release 2 topics include fuel cells, EV batteries, engines

Green Car Congress

This subtopic solicits applications that directly or indirectly address the cost and weight reduction of PEM fuel cell stacks. Applications should focus on innovative materials, manufacturing processes, and/or designs of bipolar plates. Further, a technology transfer opportunity is the use of a new Argonne catalyst for reducing NO x.

New Federal-Mogul Powertrain high thermal conductivity seats and guides keep engine valves cooler; improved combustion, lower emissions

Green Car Congress

The extreme valve temperatures experienced on today’s highly boosted downsized engines can lead to reduced valve fatigue life and critical valve guide and stem seal temperatures, resulting in the need for expensive valve steel alloys.

CPT developing 48-volt electric supercharger for micro-mild hybrids

Green Car Congress

The higher-voltage variant will support moves by European vehicle manufacturers announced earlier this year to introduce 48 volt passenger vehicle power networks to help meet the requirement for lower fuel consumption and CO 2 emissions. In other words adding a useful 42kW boost for low speed overtaking and hill climbs.
