Field of the Invention
The present invention relates to an induction assembly and system for a supercharged internal combustion engine. More particularly, the present invention relates to an assembly and a system having a monolithic unitary cast housing securing a super charger assembly and three integrated intercooler assemblies allowing for both a variable rate convective heat transfer via air cooling of an exterior of the monolithic cast housing and an air cooling of pressurized discharge air discharged from the super charger assembly for combustion.
Description of the Related Art
Industrial applications of induction assemblies for supercharged internal combustion engines have included a plurality of complex air inlet runners and cylinder head attachments.
In one related matter in U.S. Pat. No. 6,029,637 (Prior), the entire contents of which is incorporated herein by reference, an induction assembly is provided with extended induction housing intakes related to a super charger arrangement. Here, the entrance of the intake runners is long extended providing great inconvenience in access, enhanced costs, and greater difficulty in disassembly and maintenance. Additionally as a detriment, the assembly cannot be provided in a single compact monolithic manner due to the long extended intakes and the requirement for differently shaped cylinder heads and accesses geometries.
Also in a similar detrimental arrangement is U.S. Pat. No. 7,426,921 (Billings, et al.), the entire contents of which is incorporated herein by reference, wherein a super charger arrangement is provided with a separate-piece-kit type of two-part air inlet casings that are bolted to a side of a rotor casing in combination with a top rotor casing cover member. The arrangement provided is substantially complex and is also weakened by positioning the separate two-part air inlet casings with bending moments being secured to the rotor casing only through a separate cover member. Several detriments to air flow, rigidity, and sound attenuation. Additionally, thermal release from pressurized air is greatly hampered limiting power gain substantively.
Accordingly, there is a need for an improved induction assembly and system for a supercharged internal combustion with enhanced process efficiencies and thermal release.
