C3.3 Industrial Engine Caterpillar

Severe Service Application - Check

Usage:

C3.3 E3J

Severe service is the application of an engine that exceeds the current published standards for that engine. Caterpillar maintains standards for the following engine parameters:

Performance such as power range, speed range, and fuel consumption
Fuel quality
Operational Altitude
Maintenance intervals
Oil selection and maintenance
Coolant type and maintenance
Environmental qualities
Installation
The temperature of the fluid in the engine

Refer to the standards for the engine or consult your Caterpillar dealer in order to determine if the engine is operating within the defined parameters.

Severe service operation can accelerate component wear. Engines that operate under severe conditions may need more frequent maintenance intervals in order to ensure maximum reliability and retention of full service life.

Due to individual applications, it is not possible to identify all of the factors which can contribute to severe service operation. Consult your Caterpillar dealer for the unique maintenance that is necessary for the engine.

The operating environment, incorrect operating procedures and incorrect maintenance procedures can be factors which contribute to a severe service application.

Environmental Factors

Ambient Temperatures - The engine may be exposed to extended operation in extremely cold environments or hot environments. Valve components can be damaged by carbon buildup if the engine is frequently started and stopped in very cold temperatures. Extremely hot intake air reduces engine performance.

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 very 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.
