Abstract:
The exhaust system of an an internal combustion engine includes a duct having an input end coupled to the engine for passing and processing the exhaust gases and fumes emitted by the engine such that the duct functions as an anti-explosion and fire arrester device. The duct includes a reenforced filter structure (3) securely and firmly mounted within and across the duct opening. The filter structure (3) is coated with a noble metal to enhance oxidation of the gases and fumes passing through the duct. An insulator layer (303) is attached about and along the outer surface of the duct and a jacket (305) for carrying a coolant is mounted - above and about the insulator layer. The insulator layer (303) isolates the coolant from the duct to ensure that the temperature on the external side of the jacket is less than a predetermined value. Simultaneously, the insulator layer isolates the duct from the coolant to enable the temperature within the duct to have a sufficiently high value to sustain oxidation of the gases and fumes.
Abstract:
A muffler for an exhaust system of an internal combustion engine having a muffler body, a first chamber defined in the muffler body, a second chamber disposed at least in part in the first chamber, and a third chamber disposed at least in part in the first chamber. The second chamber has an inlet, an outlet, and at least one side wall. The at least one side wall of the second chamber defines at least one aperture fluidly communicating with the first chamber. The third chamber has an inlet, an outlet, and at least one side wall. The at least one side wall of the third chamber defines at least one aperture fluidly communicating with the first chamber. The outlet of one of the second and third chambers fluidly communicates with the first chamber. A vehicle having the muffler is also disclosed.

Abstract:
A transport refrigeration system (TRS) and method of operating a TRS having a sorption subsystem are disclosed. The TRS includes a refrigeration subsystem and a sorption subsystem. The refrigeration subsystem includes a refrigerant, a compressor, a refrigerant condenser, a refrigerant expansion device, and a refrigerant evaporator in fluid communication such that the refrigerant can flow therethrough. The sorption subsystem includes a heat transfer fluid, a heat source, a boiler, a sorption condenser, a sorption expansion valve, a sorption evaporator, and a pump in fluid communication such that the heat transfer fluid can flow therethrough. The sorption evaporator is in thermal communication with the refrigeration subsystem.

Abstract:
Drive systems equipped with a combustion engine, as used in small vehicles and in tools, emit unpleasantly high levels of noxious substances and noise. According to the invention, noise emission is reduced by an expansion chamber in the exhaust system, which is connected to the combustion chamber via the valves during the expulsion of the exhaust gases and to the atmosphere for at least part of the remaining time. In addition, a small vehicle is described which is fitted with such a drive system which can be taken everywhere with it. For this purpose, the small vehicle is collapsible, its frame comprising a front section and a rear section, which can be folded together through a hinge in a swivelling axis parallel to the small wheels. The swivelling lever can likewise be pivoted and aligned with a swivelling axis parallel to the small wheels on the front section of the frame.
