Maserati 4200cc F136 UC - F136 UD

Engine Overhaul

Technical Description

INTRODUCTION

Derived from the F136S power unit and upgraded with a wet sump lubrication system, the new-generation engine guarantees the same high torque and power delivered by dry sump engine technology, but has been optimised and revised to enhance its reliability. Continuous timing variators on the intake camshafts. Controlled by a low-pressure hydraulic system; Motor-driven throttle (Drive by Wire). Cylinder heads in hardened aluminium/silicon alloy with high volumetric and thermodynamic efficiency combustion chamber. Crankcase in hardened aluminium and silicion alloy, completely redesigned with cast iron cylinder liners. Single-cast crankshaft in hardened steel, individually balanced, resting on five main bearings. Integrated Bosch Motronic ME7 ignition-injection system. Four overhead camshafts (two per bank) and four valves per cylinder, controlled by hydraulic tappets. Timing controlled by chains whose tension is guaranteed by two hydraulic tensioners. Wet-sump lubrication by means of an oil pump integrated into the engine, oil/water heat exchanger integrated into the upper crankcase. Cooling circuits comprising circulation of an antifreeze mix and water circulation pump driven by engine pulley. Plastic intake manifold with optimised duct lengths.
