Kubota V2403-CR-T diesel engine. 2.434L Inline 4, turbocharged. Tier 4 Final with DOC+EGR (no DEF). Powers 28-30 kW portable generators.

Overview#

The Kubota V2403-CR-T is a 2.434-liter, 4-cylinder inline turbocharged diesel engine powering portable generators in the 28-30 kW class. Tier 4 Final compliance is achieved through a diesel oxidation catalyst (DOC) and exhaust gas recirculation (EGR) — no Diesel Exhaust Fluid (DEF) is required, simplifying field maintenance and rental logistics.

Running at 1800 RPM, the V2403-CR-T delivers strong torque density from a compact package. The same engine platform is widely used in Kubota excavators, skid steers, and wheel loaders, ensuring broad parts availability through Kubota's industrial dealer network.
