RED POWER

The RED POWER engine technology developed by DOLMAR is a practical, everyday solution designed for use primarily in portable power products.

The tougher new emission standards which manufacturers are required to comply with by August 2007 or August 2008 can be achieved in various ways. Options include the use of four-stroke engines with variable valve timing, the deployment of two-stroke engines with sophisticated air intake technology, and the installation of catalytic converters to clean the exhaust gases.

The use of sophisticated air intake technology increases the overall weight of the machine, which is a significant drawback in the case of portable power tools with smaller engine capacities. In conventional two-stroke engines the unburnt fuel constituents generate high-temperature exhaust gases. Cleaning these gases with catalytic converters necessitates complicated and costly technical solutions.

As a result of so-called scavenging losses, the exhaust gases from conventional two-stroke engines contain large amounts of unburnt fuel. With the development of an optimized gas exchange management system, the engineers at Dolmar have now succeeded in halving the scavenging losses in the two-stroke engine.

Thanks to the development of this new gas exchange management system, DOLMAR’s engineers are able to use a smaller catalytic converter, which has only minimal impact on the power-to-weight ratio while simultaneously cutting fuel consumption by around 10%.

The new Dolmar engine technology is known by an acronym that is destined to establish it as a signature brand in the power products market:RED POWER.The RED POWER engine technology developed by DOLMAR is a practical, everyday solution designed for use primarily in portable power products.

In developing its present and future generations of petrol engines, Dolmar will be harnessing all three options for reducing exhaust gas emissions: the use of four-stroke engines with variable valve timing, the deployment of two-stroke engines with sophisticated air intake technology, and the incorporation of catalytic converters into the exhaust system. Today Dolmar already meets all international requirements for exhaust gas emissions by a comfortable margin, with emissions significantly below permitted levels in many cases.
