Subaru's ER12 Rammer Engine

摘要

Subaru's new ER12 Rammer Engine is said to feature a carefully balanced and engineered design, and is exclusively intended for the demanding application of rammers. With specially-designed components and overhead cam (OHC) technology, the 3hp, four-stroke engine is lightweight, yet rugged and powerful. Weighing in at around 9.07kg, the ER12 is said to offer more power and up to 2496 more output than similar competitive engines, all while being lighter in weight and designed for optimised balance and performance. The vertical cylinder design of the ER12 is slim and compact, and is said by Subaru to maintain an excellent centre of gravity to effectively transmit power to the ground, resulting in superior performance. The recoil has been integrated into the flywheel and blower housing, further enhancing balance and overall engine performance.
