Bobcat Co., West Fargo, N.D., has released its first Tier 4 loaders, which will debut with a new Bobcat-branded engine.
The Bobcat engine is a non-diesel particulate filter (DPF) engine, a feat that was achieved by designing an ultra-low particulate combustion (ULPC) engine, said Bobcat Marketing Manager Chris Knipfer. The ULPC is accomplished through an engine combustion chamber that reduces the amount of particulate matter created during combustion.
The Bobcat engines, which were blind tested by more than 700 end-users, are being manufactured by Bobcat sister company Doosan Engine Business Group in South Korea.
The following engines will be featured in these Bobcat models:
- 1.8L Bobcat engine in 400 frame-size loaders and E32 and E35 compact excavators;
- 2.4L Bobcat engine in 500 and 600 frame-size loaders; Toolcat utility work machines; E42, E45, E50 and E55 compact excavators; and
- 3.4L Bobcat engine in 700 and 800 frame-size loaders.
A major focus for Bobcat during the engine design process was increasing torque, Knipfer said. The new engines used in 500 frame-size loaders will have a 4 percent to 12 percent increase in torque.
The new Tier 4 loaders feature a machine-protection system that monitors, manages and shuts down the engine if needed, minimizing potential damage to the engine. Another new feature of the skid-steer and compact track loader line is cold weather protection. Any time the engine temperature is too low, the loader will temporarily limit the maximum engine speed (rpm) to prevent premature component wear or failure.
Other key features include the ability to service many components by opening the equipment’s tailgate and a host of operator comfort options.
