OEM Cummins KTA38 Marine diesel engine | Tonkee®

At the heart of the KTA38 engine is a 12-cylinder, V-type configuration that delivers exceptional power and torque.

The engine has a displacement of 38 liters, which allows it to generate significant power while maintaining fuel efficiency. The KTA38 is available in a range of power outputs, from 800 horsepower to 1500 horsepower, catering to different marine applications and vessel sizes.

One of the key features of the KTA38 engine is its advanced fuel system. It is equipped with Cummins' Quantum System, which optimizes fuel delivery for improved combustion efficiency and reduced emissions. The system utilizes high-pressure injection technology, ensuring precise fuel metering and atomization, resulting in better fuel economy and lower emissions.

The KTA38 engine also incorporates Cummins' advanced air handling system. It features a turbocharger with a wastegate, which helps to improve engine response and performance. The wastegate regulates the airflow to the engine, maintaining optimal boost pressure and enhancing overall engine efficiency. Additionally, the engine is equipped with an air-to-air aftercooler, which cools the compressed air before it enters the engine cylinders, increasing power density and improving fuel efficiency.

To ensure durability and reliability, the KTA38 engine is built with heavy-duty components and a robust construction.

It features a high-strength cast-iron block, forged steel crankshaft, and aluminum alloy pistons. The engine's design includes large bearings and a robust lubrication system to handle the demands of marine applications, providing long-lasting performance even in harsh operating conditions.

Maintenance and serviceability are important considerations for marine engines, and the KTA38 excels in this aspect as well. The engine is designed for easy access to routine maintenance points, with conveniently located filters, dipsticks, and inspection points. Cummins' global service network ensures that customers have access to expert support and genuine parts, minimizing downtime and maximizing vessel availability.
