4JH CommonRail Series

All four of these new engines (45, 57, 80 & 110) utilize common rail injection technology, which allows for the amount of fuel, injection timing and how often it is injected to be controlled electronically with the engine mounted ECU (Engine Control Unit). The direct injection common rail technology is YANMAR'S solution to meeting the stringent EPA Teir 3 requirments for marine engines.
