The Cummins engine models 4B3.9, 4BT3.9 and 4BTA3.9 range in horsepower from about 80 to 130 horsepower in various configurations and torque ratings. Most engines are used in Industrial applications with some automotive applications such as step vans and other light duty trucks. The 4B3.9 engine is naturally aspirated, 4BT is turbocharged and the 4BTA is turbocharged and aftercooled. Peak torque will range from the 190 lbs-ft in 80 hp engines to the low 300's in today's higher ratings. Cummins 4B3.9 engines feature single cross-flow cylinder head with two valves per cylinder. The engine has a forged steel crankshaft with integral counterweights and side mounted gear driven camshaft. The engine has a cast iron skirted cylinder block for maximum strength and rigidity. The connecting rods are forged steel, I-beam cross section with angle spit cap-to-rod interface for maximum structural strength and ease of service. The alternator, fan and water pump, are driven by a single belt with a self-tensioning idler for minimum belt maintenance. Fewer parts for less inventory and faster maintenance and repair and parts simplicity also enables engines to be serviced and repaired with ordinary service tools. The fuel system is direct fuel injection with high swirl intake ports for thorough mixing of air and fuel to provide low fuel consumption.
