Start-up Eco-Motive developing dual-fuel “H” engine; parallel, independently fueled piston banks

Green Car Congress

Each piston bank operates independently of the other but is housed within the same engine block and has separate lubrication systems. The Eco-Motive H-motor—basically two separate engines housed within the same engine block—can be powered by either gasoline or compressed natural gas (CNG), at the driver’s decision.

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.

New split-cycle concept to control diesel HCCI combustion

Green Car Congress

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.

ECONAMIQ: Flexible over-expansion with cylinder deactivation can reduce ICE fuel consumption by up to 20%

Green Car Congress

An adaption of cylinder de-activation technique called ECONAMIQ over-expansion can be applied to engines to improve fuel efficiency. Using the pressure from the exhaust gas from the active cylinders, the ‘idle’ cylinders could be expanded to extract more work out of the engine during partial load operation.

Michigan State University Receives $2.5M ARPA-E Award to Build Wave Disc Engine/Generator for Series Hybrid Applications

Green Car Congress

The award will allow a team of MSU engineers and scientists, led by Norbert Müller, an associate professor of mechanical engineering, to begin working toward producing a vehicle-size wave disc engine/generator during the next two years, building on existing modeling, analysis and lab experimentation they have already completed.

DOE to award $55.8M for advanced vehicle technologies; $35M for fuel cell and hydrogen

Green Car Congress

The Vehicle Technologies funding is targeted at a wide range of research, development, and demonstration projects that aim to reduce the price and improve the efficiency of plug-in electric, alternative fuel, and conventional vehicles. This new funding opportunity announcement will be available in early February.

Liquid Air Energy Network forms in UK; focus on transportation and energy storage

Green Car Congress

A cryogenic engine such as the Dearman piston engine produces zero emissions at the point of use; has low greenhouse gas emissions provided the liquid air or nitrogen is produced from low carbon electricity; has energy and power density on a level with battery electric technology; and has the potential for rapid refueling.
