DALLAS, Tex. – Sterling Truck Corp. will be offering the Mercedes Benz MBE4000 diesel engine on its heavy-duty trucks.

The MBE4000 is an in-line, six-cylinder, 12.8-liter diesel engine with a horsepower range of 350 to 450, and torque range from 1350 lb. ft. to 1550 lb. ft. Designed for regional freight transportation, bulk hauling, grocery distribution and vocational applications, as well as linehaul, the MBE4000 will be available on the Sterling L-Line 9500, A-Line 9500 and SilverStar.

The engine boasts a cast-iron block; induction-hardened cylinder liners, cams and crankshafts; forged steel connecting rods and a ceramic-coated piston. Valve seats are made of wear-resistant material, while the cylinders are wet-sleeved with a stainless steel seal ring under the liner flange. This, it is claimed, eliminates deformation of the seal ring under the clamp load of the high-strength cylinder head bolts.

A two-belt accessory drive system reportedly provides longer life while an automatic tensioning system prevents belts from loosening over time. n
