摘要： A compact, high performance exhaust assembly (50) for an internal combustion engine (20) or the like having a balanced chamber (52). Two substantially parallel inlet exhaust pipes (38, 40) are mounted to a first wall (74) of the chamber (52) and are axially aligned with, but independent of, two output exhaust pipes (54, 56) similarly mounted to a opposing second wall (76) of the chamber (52). Exhaust gas is discharged through the inlet pipes (38, 40), preferably in an out-of-phase relationship or alternating from one inlet pipe to the other. The exhaust gas passes a short distance through the chamber (52) and out of aligned outlet pipes (54, 56). The majority of the exhaust gas flows directly through the chamber (52) without significant expansion. The exhaust assembly (50) increases the power output of the engine.

摘要： A compact, sound-attenuating muffler for an internal combustion engine or the like. The muffler has a divergently tapered partition located near the inlet of the muffler for dividing the exhaust gases into two pulse streams with similar sound frequencies to achieve sound attenuation when the streams are converged back together. The diverging partition creates a low-pressure volume or region on the partition's downstream side where unignited fuels may accumulate. The partition is formed with a passageway to provide communication of live fire from the inlet of the muffler to the low-pressure volume for ignition of any unignited fuel. A method of communication of live fire from the inlet of the muffler to the low-pressure volume on the downstream side of the diverging partition in the muffler also is described.

摘要： A muffler for dissipating the sound component in exhaust gases from an internal combustion engine or the like is disclosed which has an enhanced useful life. The muffler includes a partition positioned across an incoming stream of exhaust gases. The partition is formed with stream dividing or splitting means which positively divides the stream into portions that can be more evenly directed throughout the muffler. This prevents destructive preferential flow of gases within the muffler. Additionally, shielding of sound absorption material in the muffler is accomplished by selecting the pattern of perforations to reduce the contact of such material with high velocity gases.

摘要： A compact, sound-attenuating muffler for a high-performance internal combustion engine is disclosed in which the muffler casing has an elongated transverse cross-section with a height dimension of only slightly larger than the height dimension of the inlet exhaust pipe and a width dimension in the range of about 2 to 41/2 times the height dimension. The muffler includes a divergently tapering planar first partition which causes gases to be expanded only in a horizontal plane toward the side walls of the muffler and further includes a second partition formed to contract or converge the gases in a horizontal plane toward a central opening. The first partition has a cup-shaped back surface so that contraction of the gases around the back side of the first partition is highly effective in attenuating sound, and both partitions are sloped in a direction toward the outlet from the muffler so as to minimize the generation of back pressure, which is not substantially greater than the back pressure in a straight pipe.

摘要： A lightweight muffler and method for muffling a noise component of a stream of gases is disclosed. The muffler includes a chamber in which gases are directed side-by-side streams flowing in opposite directions. The streams are in contact with each other for the generation of sound dampening eddy currents in the chamber, but such contact does not break down the continuous, low resistance flow of gases through the muffler. The chamber is advantageously formed as an expansion chamber in which gases: enter one end of the chamber as an annular stream concentric with the inlet pipe to the muffler, travel along the inlet pipe to the other end of the chamber, are reversed, and travel as a concentric annular stream of greater diameter in the opposite direction down the length of the chamber for discharge into a passageway leading to the outlet tube of the muffler. A second similarly formed chamber for counterflow of opposed streams and the generation of eddy current therebetween is preferably formed proximate the outlet tube of the muffler.

摘要： A muffler for an internal combustion engine or the like including a casing (21) having an inlet opening (28), an outlet opening (29), a first partition (43) secured in the casing (21) to divide incoming exhaust gases, and a second partition (46) secured in the casing (21) downstream of the first partition (43), which second partition (46) has an opening (39) through which the divided exhaust gases are converged and joined together for exiting the casing (21). The improvement in the muffler assembly which produces both sound attenuation and lower operating back pressure is to provide an intermediate partition (51) secured in the casing between the first and second partitions (43,46) which is formed to permit substantially uninterrupted or unimpeded flow of exhaust gases past the intermediate partition, while a forwardly facing concaved surface (52) reflects sound components in a direction away from the opening (39) in the second partition (46). A method of attenuating sound and reducing back pressure comprising the step of securing an intermediate partition (51) between the first and second partitions (43,46) is provided.
