Comparison, Concept, Downsizing and Fuel Economy

JAC and Ricardo develop production version of HyBoost concept; seeking 30% boost in fuel economy with same performance

Green Car Congress

SEPTEMBER 30, 2015

Anhui Jianghuai Automobile Group Co Ltd (JAC) and Ricardo are collaborating on a project to develop the Ricardo HyBoost concept ( earlier post )—a combination of low-cost technologies to deliver improved performance and fuel economy which featured recently in the Ricardo Centenary celebrations —into volume production on a JAC vehicle.

Use of a variable compression ratio (VCR) could be one technology approach to reducing fuel consumption in highly boosted (e.g., downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio.

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.
