MBE4000 APPLICATION AND INSTALLATION
1INTRODUCTION
The MBE4000 engine is water-cooled, four-stroke, direct-injection diesel engines. The
six-cylinders are arranged inline. Each has a separate fuel injection pump (unit pump) with a short
injection line to the injection nozzle, which is located in the center of the combustion chamber.
The unit pumps are attached to the crankcase and are driven from the camshaft. Each cylinder
has two intake valves and two exhaust valves.
Charge-air cooling and an exhaust gas turbocharger are standard equipment on all MBE4000
engines.
The engine has a fully electronic control system, which regulates the fuel injection quantity and
timing using solenoid valves, allowing extremely low-emission operation.
Engine braking is controlled by a hydraulically-operated constant-throttle system and by either an
exhaust brake after the turbocharger (standard) or a turbo brake.
The cylinder block has a replaceable cylinder liner. The six individual cylinder heads are made
of cast iron. The cylinder head gasket is a three-layer, adjustment-free seal with viton sealing
elements.
The pistons are made of aluminum alloy with a shallow combustion chamber recess. The pistons
are cooled by oil spray nozzles.
The crankshaft is precision-forged with seven main bearings and eight custom-forged
counterweights, and a vibration damper at the front end.
The camshaft is made of induction-hardened steel and has seven main bearings. Each cylinder has
cams for intake and exhaust valves and a unit pump.
The valves are controlled by mushroom tappets, pushrods, and rocker arms. The intake valves are
opened and closed by a valve-guided bridge.
