Superior top-end technology

To equip the WDT and WUT models for the special roles of high speed vessels they have such sophisticated features as a super-high pressure and incredibly precise injection pump, four valves per cylinder and Yanmar’s unique ‘plum blossom’ piston crowns.

Time-tested toughness

Yanmar’s successful wave-ribbed ‘monoblock’ cylinder block, stamp-forged carbon steel crankshafts and connecting rods are part of the story of strength in all CH engines. They also have a special thermo-controlled, fresh water cooling system that keeps all vital parts at optimum operating temperature, greatly saving wear and prolonging engine life. Another great advantage is the latest Yanmar marine gear, carefully matched by out own technicians to make the ideal combination of strength and smooth power drive.

Servicing simplified

Features such as inspection hatches in the block, for six cylinder models, easy access to maintenance points and simple replacement of piston rings all help the owner keep his engine at work longer hours.

High torque, toughness and lower downtime

The CHE range of engines offers excellent torque-rise characteristics in high speed and high load range, which enables super stable performance even at high loads.

The superior engine performance gives operators the following advantages:

1. Stable cruising with least speed reduction against sudden load changes

2. A wide range of propeller matching, from the passenger ship (light/medium duty) to tug boat (heavy duty)

3. Economical with wide minimum fuel consumption range, both during cruising or performing job duties

4. Produces stable engine performance even doing other job duties

Easier Routine Inspection, Easier Maintenance means less downtime

Large inspection windows on the side of the block allow in-site replacement of pistons. Lube Oil filter is easy-to-replace cartridge type. Full mechanical engine management avoids the chance of delicate and expensive electronics failing in hot, marine engine room conditions. 500 hours service interval.
