About Common Rail Technology
As a leading diesel engine manufacturer, YANMAR integrates the most advanced common rail technology into our innovative marine engines.
Common rail technology is a digitally controlled, high-pressure fuel injection and sensor system that optimizes engine efficiency & performance. This results in reduced emissions, minimal noise, and peak power output, significantly improving the engine’s overall efficiency and comfort onboard.
Multiple sensors throughout the engine intelligently feed operating conditions and performance requirements to the ECU. The system monitors the throttle position, various temperatures, rail and pressure, intake air pressures, and both crank and cam positions. Based on the feedback from the sensors, the ECU regulates fuel from the supply pump into a single high-pressure fuel rail and digitally activated injectors. This controls precisely when and how much fuel to inject. A common rail system can supply between one and five injections to each cylinder over the course of a cycle, rather than one single injection in a mechanically controlled fuel system.
Originally developed to meet strict automotive emissions regulations, the common rail technologies used in YANMAR’s marine engines have been custom marinized by YANMAR, specific to each YANMAR model and meeting YANMAR’s strict engineering standards. This brings you the latest technology in marine diesel engineering and our collection of 5x Best in Class engines.
