Idling apparatus ;
1. Determine if apparatus is to be idling longer than ___ minutes
Why high idle?
4;
higher temp for complete combustion
Electrical demand
During long engine idling periods with the transmission in neutral, the engine coolant temperature may fall below the normal operating range. Incomplete combustion of fuel is the end result of this, which can cause crankcase dilution, formation of lacquer or gummy deposits on the valves, pistons, and rings, and rapid accumulation of sludge in the engine. Always engage the high idle feature of the engine when long periods of idling are expected.
When on scene with all warning lights activated, engage the engine high idle feature. Doing so will assist the alternator in keeping up with the electrical current demands placed on it and prevent the Load Manager from “cutting out” electrical accessories due to insufficient current flow.
Try not to shut down engine unless coolant temp is ___ or less.
*why
195
Stopping a turbocharged engine immediately after high-speed operation may cause damage to the turbocharger as it will continue to turn without an oil supply to the bearings. Failure of turbo oil seals and/or bearings are the likely results of this practice.
