Description
The MK4L series diesel engine for commercial water pump was designed as part of a joint operation between SMAN and Austria AVL. We produced a reinforced design and 4-valve upgrade in 2005 when we cooperate with The Southwest Research Institute (SwRI). All parts are designed and checked according to 116kW outputs and it has an applicable power range of 25-116kW with a large reliability margin. The engine provides good fuel economy and this is the most technically advanced engine in Malaysia. It has been selling well for over 20 years, with production of more than 1 million sets. This is the idle matching power for 25-116 kW water pump.
