The Effects of Long Term High Idle Operation on Diesel Engines

Abstract

There is a common belief among users of DoD diesel-driven (DED) generators that extended operation of diesel engines at rated speeds and light loads (high idle) results in deterioration of performance and engine damage. Information developed during this investigation indicates that the ill effect of high idle on most military diesel engines is limited to the nuisance of carbon buildup in the exhaust system and discharging of unburned fuel (wet stacking or slobbering) in the engine vicinity when operating at low temperatures. The 15 kW and 30 kW set engines are an exception in that some of these engines wet stack lubricating oil moderate temperatures. Techniques to avoid the nuisance effects of high idle operation are presented. Recommendations are made with the goal of improving operating efficiencies and reducing life cycle costs.
