Abstract
An exhaust device of an internal combustion engine for reducing exhaust sound and for suppressing the occurrence of a torque valley. A sound-deadening and pressure-dissipating device connected to the downstream end of an exhaust pipe includes a spherical member having an opening portion opening toward a downstream edge of the exhaust pipe. Exhaust gas from the exhaust pipe is reflected by an inner spherical surface of the spherical member to reduce exhaust pressure in the spherical member and then is discharged from the opening portion.
Claims20
An exhaust device of an internal combustion engine, the exhaust device being adapted to discharge exhaust gas of the engine through an exhaust pipe, comprising:
- a sound-deadening and pressure-dissipating device connected to a downstream end of the exhaust pipe;
- wherein the sound-deadening and pressure-dissipating device includes a spherical member having an opening portion opening toward a downstream edge of the exhaust pipe, and
- exhaust gas from the exhaust pipe is reflected by an inner spherical surface of the spherical member to reduce exhaust pressure in the spherical member and then the exhaust gas is discharged from the opening portion.
An exhaust device adapted to be used with an internal combustion engine, comprising:
- a sound-deadening and pressure-dissipating device connected to a downstream end of an exhaust pipe;
- a spherical member operatively provided in the sound-deadening and pressure-dissipating device, said spherical member having an opening portion opening toward a downstream edge of the exhaust pipe, and
- an inner spherical surface of the spherical member reflects the exhaust gas from the exhaust pipe to reduce exhaust pressure in the spherical member and thereafter discharging the exhaust gases from the opening portion.
