Perkins Eases Engine Changeover

By Rod Sutton, Editor in Chief | September 28, 2010

The Perkins 1100D Series includes the four-cylinder 1104D-E44TA. Engines have been designed to allow manufacturers to move from Tier to Tier without undue reengineering.

Perkins 1100D Series diesels give the company a worldwide engine platform that enables manufacturers to pick and choose engine configurations depending on where the machine will end up working. For end-users, that means a compliant engine using Caterpillar's ACERT technology that will meet any emissions standard.

With prototypes shipping this month, and full production beginning in June, the 1100D Series consists of new four- and six-cylinder, 1.1-liter-per-cylinder engines.

The D Series offers more power and torque from the same-sized packages. A key contribution to this comes from a goal to achieve a zero percentage rise in heat rejection from coolant over current models, so existing cooling groups can be installed, keeping costs and engineering down.

Boosts in engine performance include up to 43 percent more power and 51 percent more torque available across the range, with top specification units rated at more than 250 horsepower.

Despite the increase in power, cost of ownership and fuel consumption will remain comparable with existing Tier 2 engines. Fuel tolerance is increased to permit the use of lower lubricity fuels and a wider range of fuel types.

Also reduced in the new series was noise levels, between 3 and 5 dB(A), as a result of European directives set to take effect in 2006. Perkins has engineered out noise from many components, including block, oil pan, timing gear, gear train and pistons.

Serviceability remains a high priority both in terms of engine design and network support. Features including multi-vee belts and service cylinder liners will eradicate time-consuming tasks such as tensioning and cylinder rebores, shortening service time and improving cost of ownership. With service intervals maintained at 500 hours and the option to choose a 1,000-hour service interval, the end-user is faced with increasing choice.
