Engine Specifications
Note: The front end of the engine is opposite the flywheel end of the engine. The left and the right sides of the engine are determined from the flywheel end. The number 1 cylinder is the front cylinder.

(1) The operating rpm is dependent on the engine rating, the application, and the configuration of the throttle.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
Control of the injection pressure
Cold start strategy
Automatic air/fuel ratio control
Torque rise shaping
Injection timing control
System diagnostics
Aftertreatment Regeneration For more information on electronic engine features, refer to the Operation and Maintenance Manual, "Features and Controls" topic (Operation Section).Engine Diagnostics
The engine has built-in diagnostics in order 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 and the vehicle speed may be limited. The electronic service tool may be used to display the diagnostic codes.There are three types of diagnostic codes: active, logged and event.Most of the diagnostic codes are logged and stored in the ECM. For additional information, refer to the Operation and Maintenance Manual, "Engine Diagnostics" topic (Operation Section).The ECM provides an electronic governor that controls the injector output in order to maintain the desired engine rpm.Engine Cooling and Lubrication
The cooling system and lubrication system consists of the following components:
Belt driven centrifugal water pump
Water temperature regulator which regulates the engine coolant temperature
Gear-driven rotor type oil pump
Multi plate oil coolerThe engine lubricating oil is cooled and the engine lubricating oil is filtered.Engine 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.Aftertreatment System
The aftertreatment system is approved for use by Caterpillar. In order to be emission-compliant only the approved Caterpillar aftertreatment system must be used on a Caterpillar engine.The aftertreatment system is Diesel Oxidation Catalyst (DOC) and Selective Catalytic Reduction (SCR), with Diesel Exhaust Fluid (DEF) injection.The engine is connected by a flexible pipe to the aftertreatment. The exhaust gases pass through the DOC and then the mixer where the gases are mixed with the injected urea. The mixture then enters the SCR catalyst. Here the NOx in the exhaust reacts with the ammonia from the injected urea to split the gases into nitrogen and oxygen constituents. The SCR catalyst includes an ammonia oxidation section to clean up any remaining ammonia before the gases exit the system.Aftertreatment Configuration
The engine can be configured with a top mounted aftertreatment or an aftertreatment mounted across the rear of the engine.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.
Note: The front end of the engine is opposite the flywheel end of the engine. The left and the right sides of the engine are determined from the flywheel end. The number 1 cylinder is the front cylinder.
