In one embodiment, the system includes a cylinder block that forms at least part of an air compressor housing. The system may improve engine balance and reduce engine assembly cost. ## Claims ### Claim 1 A system, comprising: a V type engine block having a plurality of cylinders for housing a plurality of pistons, said engine block forming at least a portion of a supercharger air compressor housing, said supercharger air compressor housing having an inlet for fresh air and an outlet that provides compressed air to cylinders in said V type engine block; a cylinder head receiving air from said supercharger air compressor housing; and a compressor scroll or rotor surrounded by the supercharger air compressor housing. ### Claim 2 (depends on 1) The system of claim 1 where said V type engine block includes a span extending from a first engine block wall to a second engine block wall and at least partially covering the compressor scroll or rotor fitted into said V type engine block, and where said cylinder head is at least one cylinder head coupled to said V type engine block. ### Claim 3 (depends on 2) The system of claim 2 further comprising an intercooler coupled to said V type engine block, said intercooler located above said compressor scroll or rotor. ### Claim 4 (depends on 1) The system of claim 1 where said at least a portion of said supercharger air compressor housing is located in between cylinders in a valley of the V type engine block. ### Claim 5 (depends on 1) The system of claim 1 where said V type engine block includes a machined surface on an inside of said supercharger air compressor housing for sealing a lower section of the compressor housing from an upper section of the compressor housing. ### Claim 6 A system, comprising: a V type engine cylinder block having a plurality of cylinders for housing a plurality of pistons, said engine cylinder block forming at least a portion of a supercharger air compressor housing; an intake manifold in communication with said supercharger air compressor housing; and an intercooler positioned in an air path downstream of said supercharger air compressor housing and upstream of said intake manifold. ### Claim 7 (depends on 6) The system of claim 6 where said intercooler is coupled to said V type engine cylinder block and said intake manifold. ### Claim 8 (depends on 7) The system of claim 7 where said intercooler is in communication with at least a coolant passage of said V type engine cylinder block. ### Claim 9 (depends on 8) The system of claim 8 where said intake manifold includes a port for bypassing said supercharger air compressor housing and said intercooler. ### Claim 10 (depends on 6) The system of claim 6 where said intercooler is positioned in a valley of said V type engine cylinder block. ### Claim 11 (depends on 6) The system of claim 6 where at least one compressor rotor or scroll is located within said supercharger air compressor housing and where said at least one compressor rotor or scroll is driven by a crankshaft. ### Claim 12 A system, comprising: an engine cylinder block having a plurality of cylinders for housing a plurality of pistons, said engine cylinder block forming at least a portion of a supercharger air compressor housing, said supercharger air compressor housing including at least one at least partially machined surface for accommodating a compressor rotor or scroll; at least one cylinder head coupled to said engine cylinder block; and a port in the engine cylinder block for inducting gases directly from a crankcase to said supercharger air compressor housing, said crankcase at least partially formed by said engine cylinder block, and an oil separator positioned along said port. ### Claim 13 (depends on 12) The system of claim 12 where said at least one at least partially machined surface is inside said supercharger air compressor housing and where said compressor rotor or scroll is driven by a crankshaft, said crankshaft coupled to said engine cylinder block. ### Claim 14 (depends on 12) The system of claim 12 where the engine cylinder block further includes a supercharger air compressor inlet and outlet. ### Claim 15 (depends on 12) The system of claim 12 further comprising an intercooler coupled to said engine cylinder block, said intercooler located above said compressor scroll or rotor, said intercooler in communication with at least a coolant passage of said engine cylinder block or with said at least one cylinder. ### Claim 16 (depends on 12) The system of claim 12 where said at least one at least partially machined surface is machined referenced to a datum of said engine cylinder block. ### Claim 17 (depends on 15) The system of claim 15 further including a manifold directing compressed air from said intercooler to said at least one cylinder head.
