Honda GP-H engine ensures easy starting, easy usage, outstanding fuel economy, low emission and long-lasting durability as well as compact designs.  High-efficiency Impeller

By the CFD* analysis, the flow around the blade surface was optimized. Adopting efficient 4 blade realized pumps high performance. The invisible water flow inside the pump becomes visible with the analysis using computer simulation. This water flow visualization is the basis of the Impeller geometry optimization. The new highly efficient impeller enables a smooth flow with minimal resistance. This minimizes energy loss, realizing high efficiency.
