Abstract: A muffler has inner and outer elongated concentric and radially spaced generally cylindrical casings having inlet and outlet ends, and providing an annular chamber therebetween. The outer casing has an inlet opening into the annular chamber adjacent the inlet end of the outer casing so that air may flow to the outer end. The inner casing has an aperture adjacent the outlet end for the air to flow from the annular chamber into the inner casing for discharge with the exhaust. This air flow through the annular chamber reduces the temperature of the outer casing from that of the inner casing. Baffles are provided in the inner casing, and insulating material may also be provided in the inner casing.

Abstract: A controlled auto-ignition or spark ignition two stroke piston engine, fed by homogeneous air-fuel mixture, with crankcase scavenging, in which the amount of air-fuel mixture transferred from the crankcase to the cylinder is not greater than the 50% of the cylinder volume; said engine has reed valves in the transfer ports that connect the crankcase to the cylinder to control the internal dynamics of the air-fuel mixture, limiting the instantaneous maximum flow that is transferred to the cylinder in order to achieve the best stratification level among the air-fuel mixture and the exhaust residual gases, getting this way the thermo chemical activation of part of the fuel contained in the mixture. Said engine also has a rotary valve adjacent to the cylinder exhaust port that rotates in synchronism with the crankshaft, which closes the exhaust port a few degrees after the piston reaches the bottom dead center, thus preventing the leakage of the thermo chemically activated mixture and holding part of the burnt gases inside the cylinder. Then, during the compression stroke, more heat is given to the thermo chemically activated mixture decomposing part of the fuel contained in it into activated radicals which act as igniters when close to the top dead center firing the mixture in a simultaneous and complete way, thus obtaining very low levels of CO, HC and Nox emissions, as well as low fuel and oil consumption.

Abstract: A muffler suited for use in discharging exhaust gas from an engine. The muffler generally includes a housing that defines a muffler interior, an inlet aperture, and an outlet aperture. A baffle that defines a baffle interior is positioned to divide the muffler interior into an inlet space and an intermediate space. A first aperture is defined within the baffle to provide fluid communication between the inlet space and the intermediate space and a second aperture is formed within the baffle to provide for fluid communication between the intermediate space and the baffle interior. A flow guide is integrally formed with the baffle and is positioned to direct exhaust gas from the baffle interior through the outlet aperture.

Abstract: An exhaust system of a multi-cylinder internal combustion engine, particularly in a motor vehicle, has a first exhaust-gas line for receiving the exhaust gas from a first cylinder group of the internal combustion engine, a second exhaust-gas line for receiving the exhaust gas from a second cylinder group of the internal combustion engine, an exhaust-gas expansion chamber and an exhaust-gas outlet line, leading out of the exhaust-gas expansion chamber. The first and second exhaust-gas lines lead into an exhaust-gas mixing chamber which is coupled in gas flow communication with the exhaust-gas expansion chamber, so that exhaust gas can expand via the perforation of the exhaust-gas mixing chamber, into the exhaust gas expansion chamber.

Abstract: An exhaust system for use in combination with a combustion engine. The exhaust system includes a silencer having an outer casing that defines an interior and an internal construction within the interior and co-extruded with the outer casing so that the outer casing and the internal construction constitute a one-piece extrusion. The outer casing has a length in a longitudinal direction and a substantially uniform cross-section in a transverse direction. The internal construction has at least one wall that extends the length of the outer casing to define with the outer casing at least two longitudinal chambers within the interior of the outer casing. The wall has a deformed portion and passages through the deformed portion so that the silencer has a path through which gas flows from a first of the two longitudinal chambers and through the passages into the second longitudinal chamber, resulting in noise reduction for the combustion engine.

Abstract: An exhaust that has two isolated baffle systems in one container. This allows the exhaust from one manifold to be muffled and exhausted independently of the other manifold's exhaust. Moreover, the muffler is the same size as existing mufflers, so that it fits into the space of the prior art mufflers. Using two independent muffler elements (baffles and outer covering cans) eliminates all of the problems discussed above and increases the engine horsepower without reducing efficiency. An outer shroud covers the two muffler elements and is also designed to act as a heat exchanger. Fresh air can be pulled through the muffler to be heated for cabin heat and for carburetor heat. The shroud has space around the muffler cans, through which the fresh air passes. Inlet and outlet ports are provided to allow hoses to be connected as needed.
