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

Green Car Congress

FEBRUARY 5, 2010

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.

New split-cycle concept to control diesel HCCI combustion

Green Car Congress

OCTOBER 25, 2010

The basic idea of the new Diesel combustion illustrated in this paper is to control the heat release rate by a gradual supply of an almost homogeneous charge, without relying on exhaust gas recirculation to moderate the reaction. Thus the HCPC range can extend to all engine operating conditions, including very high loads. Tamagna, D.,

It expands all the way to ambient pressure before the exhaust stroke. The power is produced in almost a 50-50 split between the combustion (central) and exhaust (largest) pistons. This is a major step toward our goal of building the most efficient engine in the world for trucks, automobiles and power generation.

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.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

MAY 23, 2009

The HPE was long thought to be a system in which all engine valves had to be actuated in a fully variable manner to allow for two-stoke pneumatic modes and still enable the four-stroke combustion mode. In large naturally-aspirated SI engine, high-friction, pumping losses and part-load operation all contribute to poor fuel efficiency.

DECEMBER 30, 2015

High-pressure air jet controlled compression ignition (JCCI) is based on a compound thermodynamic cycle and is implemented in a hybrid pneumatic engine (HPE) as proposed by Schechter in 1999. The application of HPE is also beneficial to the fuel consumption and emissions because of its several flexible operation modes.
