Ford E85 Direct Injection Boosting Study: A Less Expensive Alternative to Diesel

Green Car Congress

Proposed by John Heywood and colleagues at MIT in 2005, the basic premise of E85 boosting is that ethanol (or other lower alcohols) suppresses knock due to the large evaporative cooling effect it has on the air-fuel mixture when injected directly into the cylinder, supplemented by ethanol’s inherent high octane number.

Controlled Power Technologies Packages Its Switched Reluctance Systems in ‘RegEnBoost’ System for Enhanced Support for Downsizing

Green Car Congress

CPT says that the RegEnBoost system enables a typical family-sized car to achieve less than 100 g/km CO 2 with a 1-liter gasoline engine, but when required can offer the same lively performance and in-gear acceleration of a 2-liter naturally aspirated powertrain. They have also designed a 100 mpg UK (83 mpg US, 2.8
