Cummins off-highway diesel engines refer to a category of heavy-duty, high-performance engines designed for non-road applications, including construction machinery, agricultural equipment, mining vehicles, and industrial power systems. Unlike on-road engines (e.g., trucks or buses), these engines prioritize durability, fuel efficiency, and adaptability to harsh operating conditions‌.

‌Cummins marine engines are globally recognized for their reliability, fuel efficiency, and adaptability to diverse marine applications. Designed for both ‌propulsion‌ and ‌auxiliary power‌, these engines are widely used in commercial vessels, fishing boats, ferries, yachts, and offshore platforms. Cummins integrates advanced technologies such as ‌electronic controls‌, ‌turbocharging‌, and ‌aftertreatment systems‌ to meet stringent emission standards (e.g., IMO Tier III, EPA Tier 4) while ensuring high performance and durability.

For over a century, the trucking industry has advanced combustion technology while protecting the planet. This effort involved partnering with policymakers to set emissions standards. When emissions like nitrogen oxides (NOx) and particulate matter (PM) were identified, Cummins collaborated with regulators to create cleaner diesel engines and components.
