Kohler Diesel Liquid-Cooled

KDW1003

KDW1003

The diesel engine delivers the Performance Engineering standards you've come to expect from Kohler. An advanced injection system uses fuel more efficiently while high-efficiency combustion significantly lowers emissions. The belt-driven, overhead camshaft and low-turbulence means quieter operation. Liquid-cooled, three cylinders, horizontal shaft, cast iron block construction, aluminum cylinder heads and multiple power takeoff points means maximum performance for a variety of applications all backed by a 3-year full warranty.

Overview

User-Friendly.

Compact size and low weight allows for easy installation and the extensive selection of available accessories gives flexibility to power many different applications.

Comfortable Operation.

Smooth operation due to superior balance and lower cylinder volume. Belt driven camshaft, low turbulence pre-combustion chamber and indirect injection all contribute to reducing noise.

Features

Reliability and Long Life Design.

  • Advanced injection system that delivers fuel more efficiently.
  • Superior performance over a broader rpm range.
  • High-efficiency combustion which significantly lowers emissions to meet all CARB, EPA and EURO emissions standards.
  • Lower vibration caused by a combination of fewer moving parts, superior balance and lower cylinder volume.
  • Reduced sound due to belt-driven overhead camshaft, low-turbulence precombustion chamber and inherently quieter indirect injection design.
  • Compact, heavy-duty design with multiple power takeoff points for increased application flexibility.

1 Power (hp) and Torque (lbs ft) specifications for Kohler general purpose engines are rated pursuant to Society of Automotive Engineers (SAE) J1940 based on gross output testing performed according to SAE J1995 without the air cleaner and muffler. Actual engine power and torque are lower and affected by accessories (air cleaner, exhaust, charging, cooling, fuel pump, etc.), application, engine speed, ambient operating conditions (temperature, humidity and altitude) and other factors. This J1940 / J1995 rating provides consistent measurement to customers who may want to control the intake and exhaust features of the engine. For more information, contact Kohler Co.
