Turbocharger system with internally isolated turbocharger oil drainback passage

Abstract

The invention relates to a turbocharger system with internally isolated turbocharger oil drainback passage. The invention provides a turbocharger system of an internal combustion engine. The system comprises a turbocharger system with a practical pedestal, wherein the practical pedestal extends between the turbocharger and a hard point associated with the cylinder body. The practical pedestal comprises a mounting pad which connects the combined turbocharger and pedestal assembly to the engine, an inner lubricating oil supply passage and a coolant supply passage which supply the pressurized lubricating oil and coolant to the turbocharger. The turbocharger system with internally isolated turbocharger oil drainback passage conveys waste oil from the turbocharger to a crankcase sump without permitting the waste oil to contact moving parts of the engine.

Description

technical field [0001] The present invention relates to a turbocharger system comprising not only a turbocharger but also a mounting base provided with utilities required to operate and position the turbocharger, wherein the utilities include Internally isolated turbocharger oil return passage. Background technique [0002] Turbocharging has been used in internal combustion engines for many years. While earlier turbochargers were typically cooled primarily by air and oil flow through the turbocharger bearings, later types of turbochargers, especially large turbochargers and those installed in heavy-duty engines The compressor is typically cooled with coolant that circulates from the engine's cooling system through the turbine and back into the engine's main cooling system. Of course, a turbocharger also requires an oil supply utility and an oil discharge utility to lubricate the bearings associated with the turbocharger. Needless to say, providing a source of coolant and ...

AI Technical Summary

Problems solved by technology

Unfortunately, the external fluid connections and associated plumbing and hoses pose problems as hoses are known to leak and suffer damage which is accelerated by the high temperatures prevailing in the engine compartment

Furthermore, in addition to durability concerns, the need for external piping for turbochargers increases the space required by turbochargers in an already congested under-hood environment

[0003] There is another reason why turbochargers mounted on engines usually consume a lot of space

Because known mounting arrangements make it difficult to locate the turbocharger close to the engine block, the turbocharger must be spaced from the engine to allow insertion of the turbocharger's fasteners

Furthermore, known turbocharger mounting systems increase radiated noise due to lack of rigidity and size issues associated with their use
