In this detailed technical video, we explain how the high-pressure pump operates in the MAN 48/60CR common rail diesel engine – one of the most advanced large-bore 4-stroke engines used in marine propulsion and power generation.
Discover the key working principles:
Fuel metering via electromagnetic throttle valves and suction valves.
Multiple redundant high-pressure plunger pumps (driven by triple cam lobes on the camshaft).
Pressure build-up up to 1,800 bar delivered to separate rail units.
Separation of pressure generation from injection timing for maximum flexibility, efficiency, and low emissions.
Perfect for marine engineers, diesel mechanics, students, and enthusiasts interested in MAN Energy Solutions (formerly MAN Diesel & Turbo) common rail technology, heavy fuel oil (HFO) operation, and modern diesel injection systems.
If you're working on MAN 48/60CR engines, overhauling fuel systems, or studying Tier II/IMO emissions-compliant engines, this breakdown will help you understand the heart of the common rail system.
