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., Tamagna, D.,

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

Green Car Congress

The injection of the additional air during transients can overcome the poor driveability usually associated with heavily downsized and supercharged engines, the team notes. In the pneumatic hybridization scheme, each cylinder is connected via a fully variable charge valve to a shared pressure tank. Dönitz et al. Source: ETH Zürich.

Revolutionary engine to make debut

Green Cars News

It is being unveiled as a one litre petrol unit and it is expected to produce around 80 per cent fewer toxins than a typical internal combustion engine. The technology divides the four strokes of a conventional combustion cycle over two paired cylinders - one intake/compression cylinder and one power/exhaust cylinder.

Dalian team proposes jet controlled compression ignition to control PCCI phasing in a hybrid pneumatic engine

Green Car Congress

Researchers at the Dalian University of Technology have proposed a novel method to control premixed charge compression ignition (PCCI) phasing in internal combustion engines in all load operations. It compresses the pressurized gas produced by exhaust gas turbocharger, comprising fresh air and exhaust gas introduced from the EGR valve.

Scuderi Group Unveils Cutaway Model of First Production Prototype of Split Cycle Engine

Green Car Congress

The prototype is of the naturally-aspirated Split Cycle gasoline engine, and is intended to be a proof of the basic technology of the split cycle with firing after Top Dead Center (one of the key attributes of the engine and cycle). As a result, Scuderi said, combustion is four times faster than in a conventional engine.
