Abstract
The invention relates to an extractor manifold for an internal combustion engine including a pipe having a portion with a locally reduced internal diameter so as to thereby form a venturi, and a portion that is adapted to promote swirling of exhaust gas passing there through.
Claims13
An extractor manifold including a pipe having a portion with a locally reduced internal diameter so as to thereby form a venturi, and a portion that is adapted to promote swirling of exhaust gas passing there through.
An exhaust extractor manifold including at least two upstream pipes converging at a connector portion, the connector portion having an upstream end that is adapted so as to accept the upstream pipes and define a substantially helical path in a downstream direction, the assembly further including a pipe having a portion of locally reduced internal diameter and a portion that is adapted to promote swirling of exhaust gas passing there through, wherein the pipe is inserted in a further pipe of the assembly in a position located downstream of the connector portion, so that the connector portion and the pipe are adapted to co-operatively define a substantially helical path for exhaust gasses in a downstream direction of the connector portion.
An exhaust extractor manifold including at least two upstream pipes converging at a connector portion, the connector portion having an upstream end that is adapted so as to accept the upstream pipes and define a substantially helical path in a downstream direction, the assembly further including a portion of pipe having a portion of locally reduced internal diameter and a portion that is adapted to promote swirling of exhaust gas passing there through, wherein said portion of pipe is in a position located downstream of the collector pipe so that the connector portion and said portion are adapted to cooperatively define a substantially helical path for exhaust gasses in a downstream direction of the connector portion.
An installation in which there is an internal combustion engine, with an extractor having one or more of the above-mentioned features.
