摘要： Verfahren zum Betrieb einer fremdzündenden Verbrennungskraftmaschine, wobei die Verbrennungskraftmaschine mit Wasserstoff als Kraftstoff betrieben wird und die Verbrennungskraftmaschine eine Vielzahl von Brennräumen umfasst, wobei a) auf Grundlage eines zumindest einem Brennraum zugeordneten Klopfsignalwertes sowohl eine Einspritz-Kraftstoffmenge des zumindest einen Brennraums als auch eine Einspritz-Kraftstoffmenge zumindest eines anderen Brennraums bestimmt wird, vorzugsweise die Einspritz-Kraftstoffmenge des einen Brennraums so bestimmt wird, dass der Klopfsignalwert des einen Brennraums abnimmt, insbesondere vorzugsweise, der eine Brennraum mit einem magereren Wasserstoff/Luft-Gemisch betrieben wird und an dem zumindest einen anderen der Vielzahl von Brennräumen die Einspritz-Kraftstoffmenge so bestimmt wird, dass eine Gesamt-Vorgabe-Kraftstoffmenge, die eine vorgegebene Menge von allen Brennräumen zuführendem Kraftstoff ist, so nah wie möglich angenähert wird, nochmals bevorzugt erreicht wird.

摘要： A precombustion-chamber type gas engine, comprising includes: a check valve disposed in the precombustion-chamber gas supply passage and configured to block a backflow of fuel gas from a precombustion chamber; a supply pressure control valve which is disposed on an upstream side of the check valve in the precombustion-chamber gas supply passage and which is capable of adjusting a pressure of the fuel gas to be supplied to the precombustion chamber; a torch strength information acquisition device configured to obtain torch strength information correlated to strength of a torch from the injection nozzle, on the basis of a pressure in the main chamber and a pressure in the precombustion chamber; a precombustion-chamber gas supply amount calculation device configured to calculate an amount of the fuel gas to be supplied to a precombustion-chamber gas supply amount, on the basis of the torch strength information and correlation information representing a correlation between the torch strength information, a thermal efficiency, and the precombustion-chamber gas supply amount; and a precombustion-chamber gas supply pressure control device configured to control the supply pressure control valve on the basis of the precombustion-chamber gas supply amount calculated by the precombustion-chamber gas supply amount calculation device.

摘要： A method of operating a gaseous fuel internal combustion engine comprises performing at least one measurement relating to the combustion of a mixture of gaseous fuel and air in a combustion chamber (16) of an associated cylinder (26) in a combustion cycle. At least one combustion parameter, for example, a start of combustion, is determined based on the at least one measurement. When the combustion parameter differs from a desired combustion parameter, an ignition device (90) associated with the cylinder (26) is controlled based on the comparison in order to control the combustion in the current combustion cycle.

摘要： The invention relates to a method for operating an internal combustion engine (1) having at least one piston/cylinder unit (2), preferably a plurality of piston/cylinder units (2), wherein, in a detection mode of the internal combustion engine (1), one or more knock-promoting measures are implemented until knocking arises in at least one piston/cylinder unit (2) and the measure or measures are further intensified until a termination criterion is reached, wherein it is detected in which one or more of the piston/cylinder units (2) knocking arose and wherein, for the piston/cylinder units (2) in which knocking was detected, the ignition instant is delayed for a normal operating mode of the internal combustion engine (1).

摘要： A system and method selectively reduce power of an engine having at least one piston movable in a cylinder and an exhaust port includes providing an exhaust valve in communication with the exhaust port of the engine. The exhaust valve has an adjustable position to change an effective size of the exhaust port. The system and method also include sensing a condition likely to cause damage to the piston of the engine and adjusting a position of the exhaust valve to reduce a size of the exhaust port in response to sensing the condition likely to cause damage to the piston of the engine, thereby limiting power of the engine.
