Building on its mechanical 1104D-44 model, Perkins recently launched a new electronic 4.4-L engine for OEMs exporting to and manufacturing in lesser regulated territories. The 1104D-E44 is a four-cylinder engine that offers higher levels of fuel tolerance and operational robustness while meeting Tier 3 equivalent, Stage IIIA emissions standards.
Available in two versions, the 1104D-E44T is a turbocharged unit offering power ratings of 80.4 to 99.9 hp (60 to 74.5 kW), while the more powerful 1104D-E44TA (shown) is a turbocharged aftercooled model that tops out at 142.1 hp (106 kW) at 2200 rpm, with peak torque of 556 N·m (410 lb·ft) at 1400 rpm.
Designed and built at Perkins Wuxi facility in China, the new model has been engineered to specifically combat the problems of varying fuel quality in lesser regulated territories. A new upgraded fuel system increases tolerance to poor quality diesel, supported by improved filtration to capture any debris present.
The four-cylinder electronic model shares many of the components of the mechanical version allowing equipment OEMs to move seamlessly from one emissions Tier to the next, while optimizing fuel economy and boosting overall machine performance thanks to the common rail fuel injection system.
Suitable for all major applications in construction, agriculture, and electric power, the 1104D-E44T/TA offers a variety of build options for specific machine groups, enhancing its versatility in terms of integration and ongoing maintenance. Industrial Open Power Unit and generator set versions will be available when production begins in the latter half of 2014 while the company is working on a specific structured platform for tractors for 2015.
The new model has also borrowed from Perkins Tier 4 engines with multi-vee front-end auxiliary drive systems that are self-tensioning, which minimizes maintenance.
