Abstract
According to the invention, multiple-cylinder internal combustion engines comprise a lifter oil manifold assembly (LOMA) positioned in an improved and beneficial manner. In one embodiment, engines of the invention comprise an engine block comprising a V-valley in which the LOMA is mounted such that longitudinal axes of the plurality of solenoid control valves therein are positioned essentially perpendicular to a vertical axis centrally extending from an angle formed by the V-valley of the engine block. In another embodiment, V-valley of such an engine not only comprises a LOMA but also includes a balance shaft.
Claims26
A multiple-cylinder internal combustion engine comprising hydraulically-operable deactivation valve lifters, the engine comprising:
- a lifter oil manifold assembly comprising a plurality of solenoid control valves operable for activation and deactivation of lifters associated with one or more of the cylinders;
- and
- an engine block comprising a V-valley in which the lifter oil manifold assembly is mounted;
- wherein longitudinal axes of the plurality of solenoid control valves are positioned essentially perpendicular to a vertical axis centrally extending from an angle formed by the V-valley of the engine block.
A multiple-cylinder internal combustion engine comprising hydraulically-operable deactivation valve lifters, the engine comprising:
- a lifter oil manifold assembly comprising a plurality of solenoid control valves operable for activation and deactivation of lifters associated with one or more of the cylinders;
- an engine block comprising a V-valley in which the lifter oil manifold assembly is mounted;
- and
- a balance shaft positioned within the V-valley between the engine block and the lifter oil manifold assembly.
