L35MC6 and S35MC7
They are equipped with a circulation function for the fuel oil piping, and the engines can be started and stopped even with high-viscosity heavy oil C. Applying the benefits of their uniflow scavenging constant-pressure turbocharging system, they employ a super long stroke design with the bore stroke ratio increased from 3.0 to 4.0, achieving both low fuel oil consumption and low revolution speed. They have been highly evaluated due to their advantages of having a wide output range, the ability to select the optimal output and revolution speed to match the vessel type and usage according to the number of cylinders, and high performance. Since 1982, they have been installed on many newly-built ships around the world and proven their capabilities.

Development background
Developed as a main licensee of MAN Diesel & Turbo under cooperation between Kawasaki Heavy Industries, a company with extensive experience in large main engines for ocean-going vessels, and the Company, a leading manufacturer of small main engines for domestic and coastal vessels, the Hanshin-Kawasaki-MAN B&W low speed 2-stroke engines were created with the design intention of using a uniflow scavenging constant-pressure turbocharging system to expand the field of small engines.
Reasons for selection by customers
Since they can demonstrate their capabilities well when used for continuous operation in high-output areas, they have earned the trust of customers using them in such conditions.
What types of vessels are the engines suitable for?
The engines are suitable for coastal and ocean-going vessels
