Mechanical fuel system meets Tier 3

Perkins four-cylinder 1104D meets Tier-3 emissions requirements without an electronically controlled fuel system.


The new 1140D Series diesel engine from Perkins Engines, Peterborough, England (www.perkins.com), uses a mechanical fuel-management system to meet Tier-3 emissions standards. No fuel-system electronics are required.

The design includes a two-valve head, rotary fuel-injection pump, a single V-belt, and optimized inletmanifold temperatures. The fourcylinder engine is part of the company's 1100D family of four and six-cylinder engines that reportedly offer a seamless transition to Tier-3 compliance with no retooling costs or changes in production processes. Hook-up points are identical and engine-bay requirements are virtually unchanged from the engines they replace. The mechanical 1104D, for all practical purposes, is a direct one-for-one substitution that gives customers instant emissions compliance without adding any electronics to the system.

The four-cylinder, 4.4-liter 1104D with mechanical fuel management is available in normally aspirated, turbocharged, and air-to-air charge cooled configurations with power outputs ranging from 67 to 121 hp with 346-lb-ft maximum torque at 1,400 rpm. The new design also generates less noise than comparable Tier-2 engines, with no reduction in maximum torque output.

Options include a multi-V-belt accessory drive, isolated sump, an SAE B PTO. The 1104D Series engines are also available with electronic fuel-management systems using components of Caterpillar's Acert technology. The models have outputs to 142 hp and 496 lb-ft.
