Perkins introduces a new electronic 4.4-liter, 4-cylinder engine that offers higher levels of fuel tolerance and operational robustness while meeting Tier 3 equivalent/Stage IIIA emission standards. The 1104D-E44 will be available in two versions; the 1104D-E44T is a turbocharged unit offering power ratings of 80.4 hp up to 99.9 hp, while the more powerful 1104D-E44TA is a turbocharged aftercooled model that tops out at 142.1 hp at 2,200 rpm, with peak torque of 556Nm at 1,400 rpm.
Designed and built at Perkins’ Wuxi, China, facility, the new model is engineered to specifically combat the problems of varying fuel quality. A new upgraded fuel system increases tolerance to poor-quality diesel, supported by improved filtration to capture any debris present. The new 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.The company is working on a specific structured platform for tractors for 2015.
“Great efforts have been made with this engine to combat the problem of fuel quality, which can have a profound effect on productivity and in the worse scenarios severely curtail engine life,” said Simon Gray, 1100 Series product marketing manager. Not only have we achieved greater fuel tolerance but have raised the bar in terms of overall performance and durability for this package size. We can now offer OEMs a comprehensive range of engines across the board, both mechanical and electronic, that meet current and forthcoming emission standards.”
