Intake and exhaust collector for heat engine of motor vehicle, has internal cavity of tubular body or plenum conformed by loop for allowing gas flow circulation between neighboring intake/exhaust ducts

摘要

The collector (10) has an intake duct (12) emerged in a toroid or triangle shaped tubular element (14) or plenum in an internal cavity (16), which emerges a set of intake/exhaust ducts (18) to be plug into internal ducts of a cylinder head of a motor vehicle. The internal cavity of a tubular body or the plenum is conformed by a loop for allowing gas flow circulation between the neighboring ducts (18). Each duct (18) is emerged in the internal cavity along an axis perpendicular to a plane of the tubular element.
