Perkins upgrades its 1100D series

Perkins Engines, one of the main power providers to plant manufacturers, will provide Stage 3A- compliant versions of its 1100D series family of engines with either electronic or mechanical fuel injection.
The new engines will produce 51% additional torque and 43% more power than their Stage 2 counterparts, while maintaining the same 500hr service
intervals.
Using the Acert technology of parent company Caterpillar, Perkins will be able to offer electronically-controlled engines that can interface with other systems governing, say, the transmission, suspension, brakes and so on.
It will also market a mechanically-injected engine that has the beauty of simplicity, but without the added benefits that come with electronics.
Re-engineering the valve gear train, timing case, block and sump have all helped reduce the engine noise by 5dB(A), but the heat rejection to coolant remains the same, so no cooling system modifications are required. The engine mounting points remain identical to those on the Stage 2 engines.
n Perkins and Japan's Ishikawajima Shibaura Mach-inery have signed a joint venture agreement that will see a range of two, three and four-cylinder engines, based on the 400 series, built in the USA at Griffin, Georgia.
