New energy conversion and ignition systems launch at Engine Expo 2013

Swedish company Dulob is developing new systems for energy conversion and, at Engine Expo 2013 on June 4, 5 and 6, it will showcase the Vatne-Cycle – a low-pressure cycle that works with 7 bar peak pressure, resulting in thermal efficiencies comparable with the best IC engines.
The thermodynamic cycle is based on a two-stage compression and expansion of air. The Vatne-Cycle is primarily being developed for use in small or large CHP plants, where the available temperature will be in the 700ºC range. The low pressure will enable a low-cost unit to be produced with exceptional life expectancy and without NOx. Dulob is currently seeking partners and intends to make the technology available through an attractive licensing route.
Also, associated company Picopuls will showcase its new high-performance G4 ignition system at the Messe Stuttgart in June. With duration sparks of up to 1,000mA and a maximum voltage of up to 80,000V, the G4 represents a new generation of ignition technology, as it can be applied to any modern engine control system, therefore replacing the original OEM ignition coils.
The extra reliable power from the ignition system will reduce misfires under high-pressure load conditions, especially for extremely lean alternative fuel applications such as natural gas.
