The Hercules Engines 3.7 Series II diesel engine family consists of multiple model four cylinder, in-line configuration, direct injection, liquid cooled, turbocharged, turbocharged/air-to-air inter-cooled, and naturally aspirated versions of 4.00″ (101.6 mm) bore and 4.50″ (114.3 mm) stroke resulting in a displacement of 3.7 liters (226 in3).The engines were developed to meet 50 state heavy duty emission requirements through 1990 for on-highway applications in Class 2b/3 vehicles (8,500-14,500 lbs/3856-6577 Kg GVW) with ratings up to 125 BHP (93.2 KW) @ 2800 RPM. Other application areas include industrial power units, off highway mobile equipment, military and marine.This paper presents the technical objectives for the 3.7 Series II, descriptions of significant components/systems, design technical approaches, and development efforts undertaken to meet the performance/durability objectives, and the products application capabilities.
