A diffuser for a work machine having an air breathing fuel consuming internal combustion engine with an exhaust aftertreatment device periodically elevating the exhaust temperatures to a high level. The diffuser has a venturi section and the excess contaminants from an intake air pre-cleaner are directed to the throat of the venturi to aspirate and dispose of excess contaminants while cooling the exhaust flow. Additional openings in the divergent section of the diffuser assist in providing significant reductions in exhaust temperatures within a short axial envelope.

The invention discloses a method of precision controlling and detecting by improving tidal volume through introducing an R value. The method comprises steps of utilizing Pplat to calculate a system compliance C which is equal to the ratio of delta V and (Pplat - PEEP); utilizing a processing unit to calculate a real obtained tidal volume VT of the patient end and VT being equal to the result of delta V * (C-Ctube) / C; wherein, delta V represents the variation of tidal volume, PEEP represents end-expiratory esophageal pressure, Ctube represents the tube compliance. The processing unit figures out the tidal volume value VT' in the exhalation periodic time of the next time according to the real obtained tidal volume VT of this-time breathing cycle of the patient end, VT' is equal to the result of VT + delta VT*K, wherein, K represents the scaling factor of regulation controlling, VT is the real obtained tidal volume of this-time breathing cycle, VTset is a set tidal volume that can be reached as expected, delta VTis equal to the result of VTset-VT, and thus the processing unit control the opening degree of the next time air breathing periodic time, finally, the object of tidal volume controlling and precision detecting can be achieve.

An engine system incorporating an air breathing, reciprocating internal combustion engine having an inlet for air and an exhaust for products of combustion. A centripetal turbine receives products of the combustion and has a housing in which a turbine wheel is rotatable. The housing has first and second passages leading from the inlet to discrete, approximately 180°, portions of the circumference of the turbine wheel. The passages have fixed vanes adjacent the periphery of the turbine wheel and the angle of the vanes in one of the passages is different than those in the other so as to accommodate different power levels providing optimum approach angles between the gases passing the vanes and the blades of the turbine wheel. Flow through the passages is controlled by a flapper valve to direct it to one or the other or both passages depending upon the load factor for the engine.

When operating an air-breathing engine, a liquid is injected in atomized form into an air intake duct of the engine. A measurement apparatus for determining the injected drop size or the drop concentration is arranged in or on the intake duct downstream of the location of the injection. These measured values are input into a control system, which controls suitable parameters of the injection apparatus in such a manner that the determined variables are controlled to desired values or into desired value ranges.
