摘要： A spark ignition internal combustion engine includes an exhaust gas reflux device capable of refluxing exhaust gas having passed through a catalyst for exhaust gas purification to an intake passage, an ignition timing control means for setting an ignition timing retard amount capable of preventing knocking according to a NOx concentration in the exhaust gas while the exhaust gas is refluxed, a NOx concentration estimation means for estimating the NOx concentration in the exhaust gas, and a purification performance reduction determination means for determining a reduction in purification performance of the catalyst. The ignition timing control means sets the ignition timing retard amount based on the NOx concentration in the exhaust gas before passage through the catalyst if the purification performance reduction determination means determines that the purification performance of the catalyst has been reduced to a state set in advance.

摘要： An intake body, systems. and method for reducing acoustic resonance in pressure tap passages include determining and/or setting the length of the drilling tap passages to a value such that the natural frequency of each pressure tap passage is outside of or does not substantially overlap with operational frequency content of an air stream in the intake body. The intake body, systems and method reduce the possibility of exciting the natural acoustic frequencies of the pressure tap passages, and can lead to improved signal-to-noise ratio when detecting EGR flow using a delta-P measurement system.

摘要： A vehicle controller performs a throttle-valve-late-close control in which the throttle valve is held open until a delay time has passed after the fuel cut is started, and an EGR-valve-open-close control in which the EGR valve is repeatedly opened and closed. Then, the throttle valve is closed and the EGR valve is opened. In a period from a latter period of an exhaust stroke to a preceding period of an intake stroke, a valve-overlap control is executed so that a variable valve timing controller is controlled to make both an intake valve and an exhaust valve opened. A pumping loss of an engine is sufficiently reduced and an energy-regenerate efficiency can be effectively improved.

摘要： A method is provided for operating a volume-controlled internal-combustion engine having an intake tract and an exhaust system. An expansion machine is arranged in the intake tract in the flow direction of a combustion air in front of an inlet valve of the engine. An output shaft of the expansion machine is coupleable with an output shaft of the engine. A heat exchanger is arranged in the exhaust system. Before combustion air flows through the expansion machine, it is heated in the heat exchanger by exhaust gas of the internal-combustion engine. The method achieves an efficiency improvement in an internal-combustion engine with a volume-controlled load control at partial load.
