Engine is the flagship product of KIPOR. Today there are three series engines general-purpose gasoline engine, general-purpose diesel engine and multi-cylinder diesel engine. Those engines are not only equipped to KIPOR generator sets, but also directly sold to global market. Since the future emission standard demands, KIPOR continues the improvement for the fuel and engine structures to reduce the impact on environment. Today, most of KIPOR can meet EPA standard. “Green Engine” is the target of KIPOR.Due to the requirements of climate protection and environmental protection, which have continually increased in recent years, the industry has now intensified the focus of its research and development divisions on making these engines not only more efficient, but also cleaner. Thus, clean air and the preservation of natural resources have become important objectives of our development work. The challenge is to be able to bring competitive products onto the market, while paying particular attention to the technical and economic framework conditions.
