Abstract
An exhaust system for withdrawing exhaust gases as well as combustion materials from a crankcase of an engine for a U-shaped straddle carrier includes an engine exhaust line which as an exhaust outlet adjacent the engine and an elongated pipe extending from the outlet of the exhaust line to an area above the frame structure for the carrier. A tube leads from the crankcase vent outlet to the exhaust line and has an open end which is located within the line spaced inwardly from the exhaust outlet of the exhaust line. The enlarged pipe creates a venturi effect adjacent the outlet of the exhaust line which produces a negative pressure at the outlet end of the tube and sucks the combustible materials from the crankcase vent into the exhaust line where they are ignited by the high temperature exhaust gases and are burned before exiting from the enlarged pipe.
