ABSTRACT:
Gas flow pressure losses through fuel charge and exhaust gas flow conduits for internal combustion engines are greatly reduced by turning vanes in conduit flow bends of greater than 9.degree. around an inside radius of less than twice the effective diameter of the conduit. Such turning vanes are preferably given leading edge bevels of about 20.degree. to 24.degree. and trailing edge bevels of 13.degree. to 17.degree. which are substantially centered about an arc radius through the angular center of the flow bend.
