Cummins Engine Company introduces the all-new ISB 275 DIESEL ENGINE, designed especially for the fire market. The engine is part of the Interact System family of products, a new engineering platform combining electronic engine controls with high-pressure fuel-injection and high-strength components. With this fully electronic, in-line six-cylinder diesel engine, customers will enjoy unprecedented performance and longer maintenance intervals–up to 15,000 miles for oil changes and fuel filter changes. The 24-valve design also gives greater responsiveness up and down the power range, while being significantly quieter than any engine in its class. (800) DIESELS.
