Kohler Diesel
Engines

Can Tier 4-certified diesel engines be compact, reliable, and fluid efficient? Look no further than Kohler KDI series engines, the first Tier 4 engine without a DPF. Kohler found the answers in upgraded technology that enhances the combustion process, making it possible to manufacture a compact engine with significant performance. Besides this, the KDI series boasts outstanding fuel efficiency, reduced vibration and noise levels, extended service intervals, and ease of maintenance.

Kohler Industrial Engine Specs & Informational Material

 

 

The common rail injection system is especially designed for heavy-duty ag, industrial, and construction uses. The electronic control unit (ECU) works together with the fuel injection system to optimize the combustion process, giving you an engine that is powerful and clean-burning.

Kohler Turbo Common Rail engines have the Kohler Flex Emissions Management system. Both the 1903 and 2504 meet US Tier 4 Final standards with an exhaust gas recirculation system (EGR) and a maintenance-free diesel oxidation catalyst (DOC).
