Caterpillar Compact Engines Are Ready for the Future


Caterpillar is pleased to announce an expanded compact industrial diesel engine lineup that continues to offer a clear path to off-road EPA Tier 4 Interim & EU Stage IIIB compliance. Cat compact diesel engines now cover the power range from 11 to 66 hp with ten technically advanced models that meet existing Tier 3/Stage IIIA and Tier 4 Interim emission standards for North America and Europe.

The above regulations require particulate matter (PM) and oxides of nitrogen (NOx) to be further reduced by 90% beyond Tier 3/Stage IIIA standards.

Caterpillar industrial engines have been meeting the stringent Tier 3/Stage IIIA emissions requirements. In addition, they have also made installation easier for original equipment manufacturers (OEM) by carrying over ratings and rated speeds with no engine package size increase. The expanded lineup of compact diesel engines also allows for easy changeover for current, and potential, OEM customers.

The new compact models build on the success of their Tier 2/Stage II predecessors, all in the same engine package size. These new turbocharged and air-to-air after-cooled engines increase the power of the C0.5 to C2.2 compact engine range by 10%. Redesigned cylinder head coolant channels provide more even flow of coolant and fewer "hot spots". The top tank temperature has also been increased from 110°C to 112°C. A lower fan position is available for space-constrained installations.

The redesign of the governor assembly and the optimization of fuel and combustion systems have improved startup and transient capability.

A new timing case oil filler position option makes routine servicing much quicker and easier, especially in space restricted applications.

All the engines in the Caterpillar compact diesel engine lineup offer advanced features that are designed to reduce the total cost of ownership including 500 h maintenance intervals and single-side service access.

Cat C0.5 to C2.2 engines are used in more than 200 worldwide applications including turf maintenance, outdoor power equipment, construction, agricultural, welding and power generation. New niche applications have been targeted for models in the "below 20 hp" range such as auxiliary power units (APU), which is significant at a time when the on-highway industry is actively reducing engine idling.
