Concept Congress Downsizing Exhaust 
Green Car Congress
NOVEMBER 1, 2016
In its new report on downsized and boosted gasoline engine technologies ( earlier post ) the ICCT highlighted Ricardo’s work on an “extreme” Miller cycle concept with high (13:1) compression ratio (CR) and central direct injection in a downsized boosted engine. A long exhaust stroke then extracts maximum efficiency.

The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. The hardware concept.

The HyBoost concept is based on a 2009 Ford Focus in which a 2.0L In implementing this 50% downsizing by swept volume, the research team delivered zero degradation in driveability, performance or acceleration. Earlier post.). naturally aspirated four-cylinder gasoline engine has been replaced with a 1.0L three-cylinder EcoBoost engine.

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. Source: Borgwarner. Click to enlarge.

will exhibit its High Efficiency Combustion System (HECS) diesel engine at the 2011 SAE World Congress, 12-14 April at Cobo Center in Detroit. The second-generation HECS has been adapted to a downsized 1.6L A dual-wall exhaust also reduces heat loss in order to accelerate catalyst light-off during cold starts.
