Tier 4 Engine KDPF Regeneration
As the technology of diesel engines has progressed from Tier 3 to Tier 4 Final, design aspects of the engines have been fine-tuned to comply with regulations to cover regulated diesel engine exhaust pollutants.
The result is that these new diesel engines are cleaner than ever before, and in many cases more fuel efficient too. Along with this comes the need to properly manage and maintain these new generation of machines to make sure that operating costs are minimised.
