Abstract: A method is disclosed for controlling cylinder valve switching between a first valve condition and a second valve condition for transitioning between combustion modes of an engine. The method includes adjusting timing of a signal to switch between the valve conditions based on an oil degradation condition from an oil sensor, wherein the combustion modes include spark ignition and homogenous charge compression ignition.
Abstract: An engine system and method of its operation are described. The method includes: operating the combustion chamber in a four stroke cycle by repeatedly opening a first exhaust valve of the combustion chamber once every four piston strokes while holding closed a second exhaust valve of the combustion chamber; after operating the combustion chamber in the four stroke cycle, operating the combustion chamber in a two stroke cycle by repeatedly opening the first exhaust valve once every four piston strokes and repeatedly opening the second exhaust valve once every four piston strokes during a different exhaust stroke than the first exhaust valve; and after operating the combustion chamber in the two stroke cycle, operating the combustion chamber in the four stroke cycle by repeatedly opening the second exhaust valve of the combustion chamber once every four piston strokes while holding closed the first exhaust valve of the combustion chamber.
Abstract: An engine system and corresponding control method are described. As one example, the control method includes transferring one type of fuel from one fuel tank to a second fuel tank holding another type of fuel and adjusting an engine operating parameter based on the blended fuel mixture by selective operation of a first and second fuel pump.
Abstract: A variable camshaft timing (VCT) system for an internal combustion engine is described. In one example, the system includes a spool valve that displaces oil from one phaser chamber to another phaser chamber when the spool valve is moved. The system may respond faster than systems that employ a pump to move oil between phaser chambers.
Abstract: A system for an engine, comprising of a cylinder of the engine; a first injector configured to inject a first substance to said cylinder; a second injector configured to inject a second substance to said cylinder; and a controller configured to commence combustion in the engine by injecting fuel into said cylinder, where said fuel is injected by only one of said first and second injectors during said start and/or warm-up.

Abstract: A system and method are described for operating an engine of a vehicle, the engine having a combustion chamber. In one example, the method may include controlling a stability of the vehicle in response to a vehicle acceleration; and adjusting dilution in the combustion chamber of the engine to reduce surge in response to the vehicle acceleration. The dilution may be adjusted by adjusting cam timing, for example.

Abstract: An evaporator defines an evaporator volume, and boils the liquid inside evaporator volume. A mixing chamber is in communication with the evaporator volume and mixes the vapor or moisture from the liquid in the evaporator with the breathing gas of the patient. The mixing chamber is a separate structure than the evaporator. The mixing chamber and the evaporator are connected by a first connection that is repetitively connectable and disconnectable without significant destruction of a respective connection. A heater is arranged outside of the evaporator and in a heat conducting connection with the evaporator. The heater is a separate structure than the evaporator. The evaporator and the heater are connected by a second connection that is repetitively connectable and disconnectable. A liquid storage tank is in communication with the evaporator and supplies a liquid to the evaporator through a flow channel. The liquid storage tank is larger than the evaporator.

Abstract: A traffic and population counting device system and method is provided. The traffic and population counting device may be executable by a computing device and may include an entry selector configured to be selected to indicate that a shopper has entered a shopping zone and to keep a running count of a number of shoppers who enter the shopping zone. An exit selector may be configured to be selected to indicate that a shopper has exited a shopping zone and to keep a running count of a number of shoppers who exit the shopping zone. Further, a display may be configured to display a running population count of shoppers within the shopping zone. The running population count may be determined by a running difference between the running count of the number of shoppers who enter the shopping zone and the running count of the number of shoppers who exit the shopping zone.
Abstract: A method of operating an engine system is described in which a back-pressure valve of a low pressure EGR system can be modulated at a lower frequency during an EGR operation, and at a higher frequency when additional exhaust gas sensing is requested. Back-pressure valve modulation can therefore be used to promote exhaust gas mixing while providing EGR. Exhaust gas constituents in the mixed exhaust gas can then be sensed with higher accuracy by downstream exhaust gas sensors.

Abstract: A connection head for an absorber (4) of an anesthetic breathing system has a simple design and can be easily taken apart. A valve device (2) is inserted into a guide sleeve (7), which is open towards the absorber (4). A sealing ring (16), which has two sealing areas (23, 24) and fixes the valve means (2) within the guide sleeve (7), is arranged on the underside of the guide sleeve (7).
Abstract: In one approach, a method for measuring exhaust gas recirculation flow in an engine is provided. The method comprises separating EGR flow into at least a first flow and a second flow, passing the separated first flow through a restriction region, where the first flow passes through the restriction region separately from the separated second flow, combining the separated second flow and inducting the combined flows into a cylinder of the engine, where the EGR flow is separated and then combined within a common EGR passage.
