Kohler Launches Diesel Engine/Transmission Combination

February 2010

KOHLER, Wis. – February 2010 – Kohler Co. has announced an expansion of its North American diesel engine product line, which now features a combination diesel engine/transmission package with CVT (continuous variable transmission) – ideal for powering off-road utility vehicles.

The KOHLER KDW 1003 diesel power train with CVT is a complete propulsion system that combines the simplicity of driving a traditional automatic transmission (with continuously variable ratio) with the precision of a typical automotive gear box. Rated at 26.1 horsepower (1,028 cc) at 3600 RPM, this three-cylinder, liquid-cooled diesel package delivers a smooth and quiet power source for multiple off-road vehicles such as UTVs, quads and snow machines, as well as wheeled or tracked off-road equipment. The KDW 1003 also meets current EPA and CARB emission requirements.

“By offering a combined diesel engine/transmission package, Kohler presents manufacturers with a complete propulsion unit they can take and immediately build a vehicle around,” said Cam Litt, marketing manager, Kohler Engines. “All the development work — tuning the CVT to the engine’s horsepower and torque — has already been done for an OEM. Kohler’s mechanical CVT product was developed and field tested by our Lombardini diesel engine brand in Italy, whose similar product has already been specified by OEMs in Europe and India to power off-road vehicles.”

The advantage of a CVT is the ability to keep the engine RPM in its optimum power output range for all operating conditions. Unlike a conventional transmission which changes the ratio in stages by shifting gears, the CVT continuously varies the ratio. Currently used in the automotive market, a CVT provides more useable power, better fuel economy and smoother driving experience than a traditional automatic transmission. OEMs can expect greater stability because the KDW 1003 power train’s overall compact size allows it to be positioned between the vehicle’s four wheels. It also features an engine braking system available in a slowing-down phase right up to the vehicle completely stopping.

The KOHLER KDW 1003 CVT requires almost no maintenance because of a simplistic design featuring a minimal number of parts. Additionally, the power train has a sealed and air-cooled compartment to extend the belt life and prevent slippage.

The KDW 1003’s gear box incorporates two forward gears (low/high) and a reverse reduction gear specifically designed for off-road work vehicles. It also features a speed sensor, gear selection sensor and users have the option of 2- or 4-wheel drive functionality.

All KOHLER diesel engines are supported by the company’s far-reaching dealer and distributor service network and application engineering team, ready to work with OEMs in a responsive and creative manner.
