ORNL Researchers Find Thermochemical Exhaust Heat Recuperation In Internal Combustion Engines Could Provide Substantial Boosts in Second-Law Efficiency

Green Car Congress

When reforming is not used, the fuel and exhaust pass through CV2 unchanged. The basic concept of TCR involves using exhaust heat to promote on-board reforming of hydrocarbon fuels into syngas (a mixture of carbon monoxide and hydrogen). The syngas is then burned in the engine in place of some or all of the original fuel.

Secondly, the central combustion chamber is benefit for highly efficient scavenging via intake and exhaust ports without using valves. The effects of [HCCI] operation will be investigated by future accurate combustion model. Besides, higher compression ratio can be obtained for the same stroke length of linear generators.

Grail Engine Adopts Enerpulse Pulse Plugs for Forced Semi-Homogeneous Charged Compression Ignition in Concept Two-Stroke Engine

Green Car Congress

HCCI is a combustion regime in which well-mixed fuel, exhaust gas and air are compressed to the point of auto-ignition. Unlike a spark ignition gas engine or diesel engine, HCCI produces a low-temperature, flameless release of energy throughout the entire combustion chamber. Elements of the Grail Engine.
