The Deere 4.5 liter turbocharged diesel engine is the first engine model in the 300 Series family to be updated with an evolutionary series of design improvements. Features include a new cylinder head for improved engine breathing, as well as significant improvements previously introduced on selected models in the current 300 Series engine family.
This paper will highlight some of the component design changes that have resulted in improved performance, reduced heat rejection, improved gasketed joint integrity, and component standardization that provides increased engine value to the customer.
