Cat compact aims for small niche

Caterpillar has added a new, 2.2-litre compact diesel engine to its product offering for the construction and outdoor power equipment markets.

The new Cat C2.2 is a four-cylinder, turbocharged engine with air-to-air cooling, rated at 66bhp at 2,800rpm, with a peak torque of 208.4Nm at 1,800rpm. The C2.2 occupies only 0.25m3, and weighs 194kg.

The new engine meets existing Tier Three/Stage IIIA emission standards and is designed as a solid core engine platform to tackle future emissions requirements.

“The C2.2 rounds out our line of compact diesels,” said Mike Reinhart, marketing manager, Caterpillar.

“By filling a niche at the high end of the power spectrum while still offering the benefits of a very light, compact package, it supports the continuing need for fuel-efficient, reliable diesel power in small and mid-size equipment in the construction, agricultural, turf maintenance and outdoor power equipment markets.

“It gives our customers the ability to deliver “big machine” performance in a smaller, more efficient package,” he added.

Much of the C2.2’s compact design comes from a new, side-mounted turbocharger and from a redesigned cooling system, which permits use of a smaller radiator.

Other options aimed at the engine’s target market include a choice of high or low fan positions, a special low-noise fan, and electronic controlled governing.

The new C2.2 engine retains the low cost of ownership features, common on all of the engines in Cat’s compact lineup, including a 500-hour service interval, and single-side access for all service functions.

“The C2.2 delivers Cat performance and reliability to a new segment of the compact diesel market,” Reinhart added.

“With its combination of high power density, light weight, and configuration flexibility, we expect it to be very well received.”

Other engines in the range include the C0.5, which is rated from 11 to 13.7bhp at 2,800 – 3,600 rpm, right up to the C3.4, which is rated from 57.6 to 80.5bhp at 2,600 rpm.
