Both the three and four cylinder engines have the same aftertreatment system.The aftertreatment system is approved for use by Caterpillar. To be emission-compliant, only the approved Caterpillar aftertreatment system must be used on a Caterpillar engine.Clean Emission Module (CEM)
The CEM comprises of two main components in a single unit, the Diesel Oxidation Catalyst (DOC) and the Diesel Particulate Filter (DPF). The function of the CEM is to ensure that the engine exhaust meets the required emissions regulation for the country of operation.The exhaust gases pass through the DOC to remove contaminants, carbon monoxide, and hydrocarbons. The exhaust gases then enter the DPF where any particulate matter soot and ash will be trapped.The CEM uses a passive and active regeneration process to ensure that normal operation of the engine removes the soot. The soot is removed at an equal rate of which the soot is captured. The ash remains in the DPF.Electronic Engine Features
The engine operating conditions are monitored. The Electronic Control Module (ECM) controls the response of the engine to these conditions and to the demands of the operator. These conditions and operator demands determine the precise control of fuel injection by the ECM. The electronic engine control system provides the following features:
Engine monitoring
Engine speed governing
Injection timing control
System diagnosticsEngine Diagnostics
The engine has built-in diagnostics to ensure that the engine systems are functioning correctly. The operator will be alerted to the condition by a "Stop" or "Warning" lamp. Under certain conditions, the engine horsepower, the engine speed, and the vehicle speed may be limited. The electronic service tool may be used to display the diagnostic codes.There are four types of diagnostic codes: Active Diagnostic Code, Logged Diagnostic Code, Active Event Code, and Logged Event Code.The ECM provides an electronic governor that controls the injector output to maintain the desired engine RPM.Service Life
Engine efficiency and maximum utilization of engine performance depend on the adherence to proper operation and maintenance recommendations. In addition, use recommended fuels, coolants, and lubricants. Use the Operation and Maintenance Manual as a guide for required engine maintenance.Expected engine life is generally predicted by the average power that is demanded. The average power that is demanded is based on fuel consumption of the engine over a period of time. Reduced hours of operation at full throttle and/or operating at reduced throttle settings result in a lower average power demand.The aftertreatment system can be expected to function properly for the useful life of the engine (emissions durability period), as defined by regulation, subject to prescribed maintenance requirements being followed.Aftermarket Products and Caterpillar Engines
Caterpillar does not warrant the quality or performance of non-Caterpillar fluids and filters.When auxiliary devices, accessories, or consumables (filters, additives, catalysts), which are made by other manufacturers are used on Caterpillar products, the Caterpillar warranty is not affected simply because of such use.However, failures that result from the installation or use of other manufacturers devices, accessories, or consumables are NOT Caterpillar defects. Therefore, the defects are NOT covered under the Caterpillar warranty.
