The register lists here five versions with a uniform 18 kW rated output at 2,200 to 3,000 rpm. The three-cylinder inline engine measures 81 mm bore and 90 mm stroke, maximum torque stands constant at 120 Nm at 1,400 rpm. The engines are indirect-injection, certified to Tier 4 (Final or Phase-in), in the 8 to under 19 kW power category, model year 2023.
Engines in this small power class drive compact construction machinery, small generators and stationary sets; with the KSD range, Discovery Energy continues the small-diesel-engine business previously run under the Kohler brand. In this power class the KSD engines compete with small diesels from Yanmar and Kubota fitted to similar equipment.
On a used purchase, operating hours and the service history of the injection pump count, along with the condition of the waste-gate turbocharger and charge-air ducting, the tightness of the radiator and intake tract, and compatibility with low-sulphur diesel fuel; parts supply runs through Discovery Energy's distribution network.
