New split-cycle concept to control diesel HCCI combustion

Green Car Congress

A team from Universita degli Studi di Pisa (Italy) and Rolf Reitz at the University of Wisconsin-Madison are proposing a novel combustion concept—Homogenous Charge Progressive Combustion (HCPC)—based on a split-cycle principle to control HCCI combustion in diesel-fueled engines. —Musu et al., SAE 2010-01-2107.

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.

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

Green Car Congress

Before realizing the design of a hybrid pneumatic engine (HPE) in hardware, the researchers evaluated the different pneumatic engine modes (motor mode and pump mode) associated with both two-stroke and four-stroke implementations of the pneumatic concept. The hardware concept. Dönitz et al. Test bench setup. Dönitz et al.

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.

Concept: AET Reaches Final Development Stage of OX2 Barrel Engine

Green Car Congress

Each cylinder fires twice per revolution and two cylinders fire simultaneously, resulting in four times the output per revolution of a conventional four-stroke engine at the same displacement. The engine can be adapted to run any combustible gas or liquid as fuel. Tags: Concept Engines. OX2 in a test rig.

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

Green Car Congress

Wave rotor technology has been explored since 1906, although its first significant application was in 1940 by Brown Boveri Company (BBC, today ABB) which used it as a high pressure stage for a gas turbine locomotive engine. Early concept of an internal combustion wave disc engine. Hîrceagã, M.,
