摘要： A working gas circulation engine includes a combustion chamber that can expand a working gas, which has a specific heat ratio higher than that of the air, with the combustion between an oxidizing agent and a fuel; a circulation path that can allow the working gas to circulate from a suction side to an exhaust side of the combustion chamber and can supply the same again to the combustion chamber; a feed means that can feed the gas in a pressure-reduction target section, which is the section whose pressure is to be reduced, to the outside, and a control means that operates the feed means for feeding the gas in the pressure-reduction target section, when the pressure in the pressure-reduction target section is higher than a predetermined pressure that is set in advance.

摘要： An engine crankcase gas blow-by sensor. In a closed crankcase ventilation system, crankcase gases are caused to flow through a venturi which includes high pressure and low pressure taps. The high and low pressure taps are coupled to a differential pressure transducer which produces an output that is proportional to the volumetric flow of crankcase gases through the venturi. The use of a venturi in conjunction with a differential pressure sensor offers a low resistance path for the flow of crankcase gases and allows continuous monitoring of blow-by without exceeding the operating pressure limitations of various oil seals. Such a sensor is particularly suited for closed crankcase ventilation (ccv) systems, as it doesn't require venting of crankcase gases to the atmosphere, but works well in open crankcase ventilation systems also.

摘要： A fault diagnostic system of a vehicle includes a noise module that determines a noise value based on a plurality of differences between samples of a pressure signal generated by a pressure sensor located in a positive crankcase ventilation (PCV) system of an engine. A signal module determines a signal value based on the samples of the pressure signal generated by the pressure sensor located in the PCV system of the engine. A diagnostic value module determines a diagnostic value based on one of: (i) a product of the noise value and the signal value; and (ii) a sum based on the noise value and the signal value. A fault module selectively diagnoses a fault in the PCV system based on the diagnostic value and generates a malfunction indicator within a passenger cabin of the vehicle in response to the diagnosis of the fault in the PCV system.

摘要： Systems and methods for monitoring crankcase ventilation system integrity are disclosed. In one example approach, a method comprises indicating a crankcase ventilation system degradation based on a lower vacuum than expected downstream of a PCV breather tube. For example, indicating a crankcase ventilation system degradation based on a lower vacuum than expected downstream of a PCV breather tube may include indicating a crankcase ventilation system degradation based on an absolute pressure sensor measurement relative to a gauge pressure sensor measurement.

摘要： This document describes a device for cleaning of crankcase gases from a combustion engine, and a combustion engine having such a device. An inlet conduit is connected to a crankcase of the combustion engine. A centrifugal separator receives a flow of crankcase gases from the crankcase via the inlet conduit and comprises a routable centrifuge rotor for centrifuging the crankcase gases. A drive device drives the centrifuge rotor. An outlet conduit discharges cleaned crankcase gases from the centrifugal separator. The rotary speed of the drive device, and thus the rotary speed of the centrifuge rotor, is controllable depending on the gas pressure in the crankcase. An export conduit may be connected to the inlet conduit and adapted to enable discharge of a flow of crankcase gases from the crankcase by-passing the centrifugal separator depending on the gas pressure in the crankcase. An import conduit may be connected to the inlet conduit and adapted to enable feeding of a flow of air from the surroundings to the crankcase depending on the gas pressure in the crankcase.
