Mack's New Intercooled Six Cylinder Diesel, Maxidyne 300 740622

The application of an advanced state-of-the-art air inlet system has produced a high specific output, high torque rise, heavy-duty diesel truck engine. By integrating a compact plate-fin air-to-air heat exchanger with the cooling air driven by a novel tip turbine fan, a 25% increase in power output has been achieved with minimal increase in mechanical engine loads. The use of an aluminum two-piece piston which prevents side thrust loading on the ring-carrying head section results in improved ring life and reduced oil consumption.
