Abstract

A cam target wheel (630) is disclosed for a camshaft (135) of an internal combustion engine (110). The cam target wheel (630) includes first and second half wheels (610, 620), first and second half wheels (610, 620). The second half wheels (610, 620) are provided with connecting means for their interconnection.

Description

technical field [0001] The present disclosure relates to cam carrier assemblies for internal combustion engines. Background technique [0002] Internal combustion engines for motor vehicles typically include an engine block defining at least one cylinder housing a reciprocating piston coupled to rotate a crankshaft. The cylinders are closed by a cylinder head which cooperates with a reciprocating piston to define a combustion chamber. A fuel and air mixture is circulated within the combustion chamber and ignited, thereby producing thermally expanding exhaust gases that cause reciprocating motion of the piston. Fuel is injected into each cylinder through a corresponding fuel injector. Fuel is provided to the fuel injectors at high pressure from each fuel rail in fluid communication with a high pressure fuel pump that increases the pressure of fuel received from a fuel source. [0003] Each cylinder has at least two valves that selectively allow air to enter the combustion ...
