Caterpillar Marine Engines

Caterpillar introduced its first diesel engine in 1931 and, only seven years later, began selling marine engines too. Its initial three models – a V8 and two six-cylinders – produced 80-135 horsepower for heavy, continuous power loads. Since then, Caterpillar has become the largest producer of diesel engines in the world and a leader in marine power systems.

Today, Caterpillar offers diesel as well as multi-fuel engines for auxiliary power and propulsion purposes plus marine generator sets. Azimuth propulsion systems with controllable and fixed-pitch configurations are available as well as conventional propeller systems with controllable-pitch setups. These also include electrical, hybrid, and mechanical options.

Caterpillar Marine Engine Products

Caterpillar marine engines are available in three product lines:

• Commercial propulsion engines: From container ships to tugs, these durable Caterpillar engines will provide reliable power for decades.
• Marine generator sets: Caterpillar's gen sets combine new technology such as advanced controls with time-tested designs to provide onboard power every time you need it.
• Auxiliary engines: Whether you're bringing aboard cargo containers or releasing twenty miles of fishing line from a long-liner, Caterpillar's auxiliary engines generate the necessary power for every situation.

Caterpillar Marine Engine Industries

Thanks to less required maintenance which results in more uptime, Caterpillar marine engines are used in a wide variety of commercial industries:

• Cargo
• Dredge
• Ferry and cruise
• Fishing
• Governmental
• Inland waterway
• Offshore operations
• Recreational boat and yachting
• Tug and salvage

Caterpillar Marine Engine Emissions & Fuel Options

Caterpillar is committed to meeting emissions standards and increasing fuel efficiency:

• Tier IV requirements: Caterpillar offers a complete line of Tier IV Final compliant engines. This is achieved using cutting-edge selective catalytic reduction (SCR) technology which injects diesel exhaust fluid (DEF) into air exhaust systems to break down nitrogen oxides.
• Dual-fuel: Caterpillar's dual-fuel power systems incorporate dynamic gas blending (DGB) so engines can use diesel, natural gas, or a combination of the two. This generates significant fuel savings and reduces emissions.
• Propulsion: Caterpillar's twin-fin propulsion systems are available for both retrofits and new diesel-electric systems. These offer increased reliability and control in extreme operating conditions. Plus, with Caterpillar's proprietary hub mechanism system, the blades in controllable-pitch propellers can use feathering to save fuel without requiring the installation of any moving parts.

No matter the size of your ship or the industry you're working in, Caterpillar offers a marine power solution which will work for you. That's due to earning a reputation over the last 80 years which has resulted in Caterpillar becoming an industry leader.
