The Kubota D1105-K has a rated output of 24.8 horsepower, 3,000 rpm, three cylinders, and a 1.123L displacement.
Building off its D902-K, Kubota developed the D1105-K engine as a power source complying with the latest U.S., European, and Chinese emission regulations. Equipped with the TVCR combustion system, the D1105-K engine combines the company’s original combustion system with an electronic control technology developed specifically for small engines. The engine adopts the Kubota TVCR combustion system to realize both greater fuel efficiency and a compact size that makes it easy to use as a replacement to conventional Kubota engines, the company says. The D1105-K also utilizes a large oil pan, extending the period between essential regular oil changes up to 500 hours dependent on operating conditions.
The new TVCR combustion method reduces black smoke to an invisible level. Moreover, manufacturers can directly mount the ECU to the engine to reduce the burden on the machine design when swapping out the engine, which is expected to reduce the length of development.
