Environmental concerns demand more stringent emission legislations concerning new power sources for handheld equipment, like chainsaws and trimmers. Today the most common power source is the well-known two-stroke engine. This type of engine has been the natural choice due to low cost and high power density. The two-stroke engine, as we know it today is not able to comply with future emission demands due to its massive hydrocarbon pollutant. To challenge the future engine manufactures must come up with new cost efficient engine technologies that still deliver the same or improved performance for customer satisfaction. Manufactures of handheld equipment are players on a very competitive market, where the cost is the main concern in choosing a feasible technology. This paper describes the development of a sequentially stratified scavenging 25cc trimmer engine.
