Bobcat will soon begin the transition to meet EU Stage IIIB/Stage IV emission regulations for machines in Europe greater than 37 kW (50 HP). This has resulted in significant changes to engine design, added components and unique service requirements, with the incorporation of non-DPF Stage IIIB/Stage IV compliant Bobcat branded engines in selected Bobcat machines.
The new non-DPF engines, built by the Doosan Infracore Engine Business Group, will be added to selected Bobcat machines in 2015. There will be three engine models in the range from 37 kW (50 HP) to 74 kW (99 HP) with displacements of 1.8, 2.4 and 3.4 l, respectively. The engines will be used in 500, 600, 700 and 800 platform Bobcat loaders, except for the S510 and S530 models, which are below 37 kW (50 HP).
The new compact engines have been subjected to very thorough and successful trials, involving more than 140,000 hours of testing, four times more testing than that on other engines in the Bobcat range of products, to ensure they offer the reliability customers have come to expect from Bobcat compact equipment.
In addition, non-DPF technology has been chosen as a customer-preferred solution that minimises long term Stage IIIB/Stage IV parts and maintenance expenses. Engines with a non-DPF system have a simpler design, need less mounting space, have no risk of thermal damage and do not require ash cleaning. Such engines also have fewer service needs and offer enhanced fuel economy.
