Definitions

  • the present disclosure relates to a method of controlling a reciprocating internal combustion piston engine and more particularly to a method of controlling such an engine comprising a pre-chamber.
  • the present disclosure further concerns a internal combustion piston engine comprising a pre-chamber.
  • a pre-chamber In reciprocating internal combustion engines, a pre-chamber, often also known as a precombustion chamber, is used to pre-ignite a mixture of air and fuel so as to subsequently ignite and combust a mixture of air and fuel in the combustion cylinder.
  • Publication WO 2007/006062 A1 discloses a method for operation of an internal combustion engine operated with gaseous fuel, wherein, at least during one engine operation range, the combustion of the fuel gas/air mixture introduced into the main combustion chamber is achieved by ignition of than ignitable fuel/air mixture in a pre-chamber.
  • Publication WO 96/25592 A1 discloses an internal combustion engine having a combustion chamber, a pre-combustion chamber communicating with the combustion chamber, injection means located and arranged to periodically deliver controlled amount of fuel and air into the pre-combustion chamber.
  • An object of the present disclosure is to improve pre-chamber combustion and to prevent premature combustion in the combustion chamber of a reciprocating internal combustion piston engine comprising a pre-chamber.
  • the object of the disclosure is achieved by a method for controlling a reciprocating internal combustion piston engine and a reciprocating internal combustion piston engine, which are characterized by what is stated in the independent claims.
  • the preferred embodiments of the disclosure are disclosed in the dependent claims.
  • the disclosure is based on the idea of introducing a first prescribed amount of gaseous fuel and a second prescribed amount gaseous fuel into the pre-chamber such that at least to a crankshaft rotation of 30 deg is provided between introducing the first prescribed amount of gaseous fuel and introducing the second prescribed amount of gaseous fuel within a single combustion cycle.
  • the first prescribed amount gaseous fuel at least partly scavenges residual gases, such as exhaust gases, generated in a preceding combustion cycle prior to a subsequent combustion cycle, while simultaneously cooling down the tip of the pre-chamber through which it flows.
  • the interval of at least a 30 deg crankshaft rotation between introducing the second prescribed amount of gaseous fuel into the pre-chamber promotes scavenging residuals gases from the pre-chamber to the combustion chamber have enough time mix within the combustion chamber before the second prescribed amount of gaseous fuel is introduced and ignited. As a result, a more controlled and uniform combustion is achieved in the combustion chamber.
  • a first aspect of the disclosure relates to a method of controlling a reciprocating internal combustion piston engine comprising a pre-chamber.
  • the pre-chamber is in fluid communication with the combustion cylinder via a tip of the pre-chamber that extends at least partially into the combustion chamber.
  • the method comprises introducing charge gases into the combustion cylinder of the engine.
  • Charge gasses such as air, may be introduced via an inlet valve of the combustion chamber.
  • the method further comprises introducing a main amount of gaseous fuel into the combustion cylinder using a main gas admission device.
  • the main amount of gaseous fuel forms a main charge to be combusted within the combustion chamber with the charge gases.
  • the main amount of gaseous fuel may be introduced via a gas admission valve in connection with an inlet of the combustion chamber, or a direct injection device for injecting gaseous fuel directly into the combustion chamber.
  • the method further comprises introducing a first prescribed amount of gaseous fuel into the pre-chamber using a pre-chamber gas admission device.
  • this first amount of gaseous fuel at least partially scavenges any residual gases generated in a preceding combustion cycle from the pre-chamber to the combustion chamber, prior to a subsequent combustion cycle.
  • the method further comprises introducing a second prescribed amount of gaseous fuel into the pre-chamber using the pre-chamber gas admission device to form a pre-chamber charge.
  • the pre-chamber gas admission device is an electrically actuated valve, and more preferably a solenoid valve.
  • the method further comprises igniting the pre-chamber charge using an igniter at least partially disposed in the pre-chamber. Particularly, ignition of the pre-chamber charge subsequently ignites and combusts the main charge in the combustion chamber.
  • the igniter device is chosen from a spark igniter device, plasma igniter device or a laser igniter device, although other alternatives may be envisaged.
  • an interval corresponding at least to a crankshaft rotation of 30 deg is provided between introducing the first prescribed amount of gaseous fuel and introducing the second prescribed amount of gaseous fuel within a single combustion cycle.
  • an interval corresponding at least to a crankshaft rotation of 40 deg is provided between introducing the first prescribed amount of gaseous fuel and introducing the second prescribed amount of gaseous fuel within a single combustion cycle.
  • the method may comprise expelling exhaust fumes from the combustion chamber, suitably via an exhaust valve, after combustion of the main charge.
  • the first prescribed amount of gaseous fuel is introduced subsequent to closing the exhaust valve.
  • the first prescribed amount of gaseous fuel is introduced when an inlet valve is open, such that the first prescribed amount of gaseous fuel is introduced prior to a closure of the inlet valve.
  • introducing the first prescribed amount of gaseous fuel is stopped at a time period corresponding to a crankshaft rotation of 20 deg prior to the closure of the inlet valve, at the latest.
  • the second prescribed amount of gaseous fuel is introduced subsequent to the closure of the inlet valve.
  • the first prescribed amount is more than 50% of a total prescribed amount of gaseous fuel introduced into the pre-chamber. In other words, the first prescribed amount of gaseous fuel exceeds the second prescribed amount of gaseous fuel.
  • a second aspect of the disclosure relates to a reciprocating internal combustion piston engine.
  • the engine comprises a combustion cylinder with an inlet valve and an exhaust valve.
  • the engine further comprises a pre-chamber in fluid communication with the combustion cylinder via a tip of the pre-chamber extending at least partially into the combustion chamber.
  • the pre-chamber is equipped with a pre-chamber gas admission device for introducing gaseous fuel into the pre-chamber.
  • the engine further comprises a control unit operationally coupled to, and configured for controlling:
  • the inlet valve is configured to introduce charge gasses into the combustion cylinder of the engine. If a mechanically actuated inlet valve is used, this may be achieved by configuring an associated mechanism accordingly. Alternatively, if a hydraulic, pneumatic or solenoid-actuated inlet valve operationally controlled to the control unit is used, this may be achieved by configuring the control unit to control the inlet valve accordingly.
  • control unit is further configured to:
  • control unit is further configured to provide an interval corresponding at least to a crankshaft rotation of 30 deg between introducing the first prescribed amount of gaseous fuel and introducing the second prescribed amount of gaseous fuel within a single combustion cycle.
  • control unit is further configured to provide an interval corresponding at least to a crankshaft rotation of 40 deg between introducing the first prescribed amount of gaseous fuel and introducing the second prescribed amount of gaseous fuel within a single combustion cycle.
  • the main gas admission device may be provided as a gas admission valve in connection with an inlet of the combustion chamber, or as a direct injection device for injecting gaseous fuel directly into the combustion chamber.
  • the pre-chamber gas admission device is an electrically actuated valve, and more preferably a solenoid valve.
  • the igniter device is chosen from a spark igniter device, plasma igniter device or a laser igniter device, although other alternatives may be envisaged.
  • the engine comprises an exhaust valve configured to expel exhaust gasses from the combustion chamber after combustion of the main charge. If a mechanically actuated exhaust valve is used, this may be achieved by configuring the associated mechanism accordingly. Alternatively, if a pneumatic, hydraulic or solenoid-actuated exhaust valve operationally coupled to, and controllable by the control unit is used, this may be achieved by configuring the control unit accordingly.
  • control device is configured to introduce the first prescribed amount of gaseous fuel subsequent to closing an exhaust valve.
  • control device is configured to introduce the first prescribed amount of gaseous fuel when an inlet valve is open, such that the control unit is configured to introduce the first prescribed amount of gaseous fuel prior to a closure of the inlet valve.
  • control unit is configured to stop introducing the first prescribed amount of gaseous fuel at a time period corresponding to a crankshaft rotation of 20 deg prior to the closure of the inlet valve, at the latest.
