Environmental Factors
Ambient temperatures - The engine may be exposed to extended operation in cold environments or hot environments. Valve components can be damaged by carbon buildup if the engine is frequently started and stopped in cold temperatures. Hot intake air reduces engine performance and increase oil degradation.Quality of the air - The engine may be exposed to extended operation in an environment that is dirty or dusty, unless the equipment is cleaned regularly. Mud, dirt, and dust can encase components. Maintenance can be difficult. The buildup can contain corrosive chemicals.Buildup - Compounds, elements, corrosive chemicals, and salt can damage some components.Altitude - Problems can arise when the engine is operated at altitudes that are higher than the intended settings for that application. Necessary adjustments should be made.Incorrect Operating Procedures
Extended operation at low idle
Frequent hot shutdowns
Operating at excessive loads
Operating at excessive speeds
Operating outside the intended applicationIncorrect Maintenance Procedures
