Abstract
An exhaust apparatus for a combustion engine having a combustion chamber and an exhaust pipe for conveying exhaust gas in an exhaust stream from the combustion chamber wherein the exhaust apparatus includes a fan member disposed within the exhaust pipe and driven by the exhaust stream so as to create an area of low pressure between the fan member and the combustion chamber whereby extraction of exhaust gas from the combustion chamber is facilitated.
Claims18
An exhaust apparatus for a combustion engine having a combustion chamber and an exhaust pipe for conveying exhaust gas in an exhaust stream from the combustion chamber, the exhaust apparatus comprising:
- fan means disposed downstream of the combustion chamber within the exhaust pipe and driven by the exhaust stream;
- and static mixing means for imparting a swirling flow to the exhaust stream, the static mixing means being positioned upstream of the fan means, whereby swirling flow of the exhaust stream facilitates drive of the fan means.
An exhaust apparatus for a combustion engine having a combustion chamber and an exhaust pipe for conveying exhaust gas in an exhaust stream from the combustion chamber, the exhaust apparatus comprising:
- fan means disposed downstream of the combustion chamber within the exhaust pipe and driven by the exhaust stream;
- air inlet means for communicating an inner space of the exhaust pipe with a source of air;
- and static mixing means for imparting a swirling flow to the exhaust stream, the static mixing means being positioned in the exhaust pipe upstream of the fan means whereby swirling flow of the exhaust stream facilitates drive of the fan means.
An exhaust apparatus, comprising:
- a substantially tubular housing adapted for substantially sealing connection to an exhaust pipe of a combustion engine, the tubular housing having substantially the same diameter as the exhaust pipe;
- and
- fan means disposed within the housing so that when the housing is connected to the exhaust pipe, an exhaust stream from the combustion engine drives the fan means;
- air inlet means for communicating an inner space of the exhaust pipe with a source of air;
- wherein said air inlet means is positioned so as to introduce a stream of air into the housing into a plane of rotation of the fan means in a plane substantially normal to a longitudinal axis of the housing and offset from the axis so as to impart a swirling flow to the stream of air whereby rotation of the fan means is facilitated.

- fan means disposed downstream of the combustion chamber within the exhaust pipe and driven by the exhaust stream;
- air inlet means for communicating an inner space of the exhaust pipe with a source of air;
- wherein said air inlet means is positioned so as to introduce a stream of air into the exhaust pipe into a plane of rotation of the fan means in a plane substantially normal to a longitudinal axis of the exhaust pipe and offset from the axis so as to impart a swirling flow to the stream of air whereby rotation of the fan means is facilitated.
