  • Turbocharger air intake with low-pressure drop and controlled vacuum at a crankcase inlet
    Patent number: 10047706
    Abstract: An intake tube has an inner and outer curved surface adjacent a turbocharger. A crankcase hose connects to the inner curved surface at a hose opening. Upstream ends of first and second struts straddle the hose opening and extend between and connect to the inner and outer curved walls. The struts have an oval-shaped cross section with a larger upstream end that forces air between the two struts and between each strut and the adjacent tube wall to create a low pressure at the hose opening to draw gases from the hose into the intake and turbocharger.
