A charge air cooler is composed of a framed heat exchange core which is sealably attached in a selectively removable manner with any suitably shaped inlet and outlet ducts, and is, at the other sides thereof provided with cover panels which collectively necessitate that all of the hot charge air coming from the turbocharger pass entirely through the heat exchange core. In this regard, the heat exchange core is provided with a pair of opposingly disposed mounting frames, each of which being connected sealably to a commensurately sized and configured mounting flange of an inlet duct or an outlet duct.

Charge air cooler designed for tier 2 locomotive diesel engine

Engine reconfiguration kits are developed for NOx emission reduction in Electro-Motive Division of General Motors Corporation model 645 diesel engines. The kits feature improved unit fuel injectors providing better fuel atomization with retarded injection timing and other improvements. Included new higher efficiency four pass counterflow aftercoolers provide reduced airbox inlet air temperatures. New connector pipes for the counterflow aftercoolers may also be included. Optional higher compression ratio pistons are available for increased fuel efficiency in some engine types. The kits reduce NOx emissions without increasing smoke, CO or particulate emissions or reducing performance.
