摘要： A piston crown for a piston of an internal combustion engine, the piston crown extending in an axial direction along a central axis and in a radial direction outwardly from the central axis. The piston crown comprises an annular surface at a first end of the piston crown in the axial direction; and a piston bowl located radially within the annular surface and recessed relative to the first end of the piston crown. The piston bowl comprises a raised floor in a radially central region of the piston bowl; an arcuate surface located radially outward relative to the raised floor; and a lip chamfer surface extending radially outwardly from the arcuate surface and radially inwardly from the annular surface. A radially inmost portion of the lip chamfer surface is radially inside the radially outermost portion of the arcuate surface. A bowl maximum radius, Rmax, is defined as a distance in the radial direction between the central axis of the piston crown and an innermost edge of the annular surface. A bowl height, H, is defined as a distance in the axial direction between the annular surface and a surface of the piston bowl furthest from the annular surface. A lip re-entrancy angle is defined as an acute angle between a line extending in the radial direction at the first end of the piston crown and a tangent to the arcuate surface closest to the first end of the piston crown. The bowl maximum radius, Rmax, is between 2.3 and 3.2 times the bowl height, H, and the lip re-entrancy angle is between 40° and 80°.

摘要： An exhaust gas treatment assembly comprises a housing which is radially inwardly deformed in a clamping region to retain a block of ceramic or other material which may be arranged as a filter or catalyst within the housing. The clamping region is deformed to a first surface level and includes local protuberances which extend radially outwardly to a second surface level and support a mounting surface for mounting the assembly in a mounting connector. The first surface level may vary to accommodate the dimensions of each individual block while the second surface level is fixed so that the mounting surface can fit in a mounting assembly with standardised dimensions.

摘要： A flowhood is provided to which an upstream conduit and a downstream conduit of an emissions cleaning module can be connected includes a first section and a second section. The second section includes a first aperture for connection to the upstream conduit and a second aperture for connection to the downstream conduit. The first and second apertures may face substantially in the same direction to permit a compact arrangement. A body of the first section may be shaped to channel gas flow from the first aperture to the second aperture. An emissions cleaning module including such a flowhood is also described.

摘要： A heating and cooling system for a vehicle having an internal combustion engine is provided. The system comprises at least one exhaust pipe conveying exhaust gases away from the engine, and a reactor vessel located in the exhaust pipe and containing an absorbent salt and a refrigerant fluid. A condenser is in fluid communication with the reactor vessel, and receives refrigerant vapour from the reactor when exhaust gases heat the reactor vessel in the exhaust pipe. An evaporator is locatable in a cab of the vehicle and is in fluid communication with the condenser and the reactor vessel. The evaporator receives condensed refrigerant from the condenser so as to cool the air surrounding the evaporator, and returning refrigerant vapour to the reactor vessel. A method of cooling a driver environment of a vehicle having an internal combustion engine is also provided, as is a vehicle incorporating the heating and cooling system.

摘要： An apparatus for detecting urea deposits in an exhaust pipe of an internal combustion engine is provided, where the urea is introduced into the exhaust pipe in an aqueous urea solution via a nozzle. The apparatus comprises at least one radiation receiver which, in use, is located within the exhaust pipe downstream of the nozzle. The apparatus further comprises an electronic control unit in communication with the receiver, wherein the receiver communicates radiation data to the control unit which allows the control unit to establish whether deposits have formed within the exhaust pipe. A control valve is also provided which controls flow of the solution to the nozzle in response to signals from the control unit. A method of detecting urea deposits in an exhaust pipe of an internal combustion engine is also provided, as in an automotive vehicle incorporating the aforementioned apparatus.

摘要： An emissions cleaning module includes a flow conduit having an upstream end fluidly connected to a source of exhaust fluid and a downstream end fluidly connected to a mixer module. An injector module has an outlet orientated to inject injection fluid into the flow conduit upstream the mixer module. A low pressure cavity downstream the injector module outlet is fluidly connected to the flow conduit or the mixer module by an open mouth orientated such that a flow of exhaust fluid along the flow conduit flows over the open mouth creating a pressure reduction within the low pressure cavity.
