Pinnacle Engine pre-production prototype opposed piston engine shows about 27% fuel consumption improvement across different scooter cycles compared to conventional engine

Green Car Congress

Fuel mass flow comparison shows Pinnacle engine ahead at just about all points in the map. We did another study with FEV, projecting our data onto a turbo downsized application; we get nearly 50% improvements in common automobiles. Click to enlarge. Improvement during CDC: 28.7%. Improvement during WMDC: 26.2%.

Taking another look at methanol as an alternative transportation fuel for the US

Green Car Congress

In comparison, they noted, the technology for bio-chemical ethanol production from cellulosic biomass is not sufficiently developed yet. Multiple ways exist for introduction of methanol into the fuel infrastructure (light blends or heavy blends) and into vehicles (light duty or heavy duty applications).

Ricardo and Growth Energy Collaborate On First Vehicle-Based Demonstration of Ricardos Ethanol Boosted Direct Injection (EBDI) Engine Technology

Green Car Congress

Based on test work already carried out, Ricardo estimates that a fuel economy improvement of up to 30% is possible with no loss of power or performance, using a downsized EBDI engine in place of currently available gasoline powertrain technology. Comparison of different ethanol blend levels in EBDI engine. fuel economy improvement.
