Rotation (flywheel end) Counterclockwise Four Cylinder Engine C2.2
This Caterpillar C2.2 industrial engine has two variants, the turbocharged engine and the turbocharged charge cooled engine. Both engine variants have a Diesel Oxidation Catalyst (DOC) aftertreatment system. The DOC aftertreatment system does not require a service interval. Both engine variants are electronically governed with a high-pressure fuel rail system. The engines can be identified by the serial number prefix G43 or serial number prefix J26.The Caterpillar C2.2 industrial engines have the following characteristics.
In-line 4 cylinder
4 stroke cycle
Two valves per cylinder
DOC aftertreatment

Rotation (flywheel end) Counterclockwise 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 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. Reduced hours of operation will increase the length of operating time before an engine overhaul is required.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.
