Definitions

  • the present invention relates to a method for increasing amount of sucked and burnt air-fuel fluid mixture in two stroke engines in order to obtain a higher power and to an engine using said method.
  • the invention provides installing a fan within carter-pump of two-stroke engines, suitably keyed and fixed to output shaft, said fan rotating with the same number of revolutions of the output shaft, thus increasing sucked flow during phase of opening sucking channel and a subsequent increase of pumping pressure when closing carter and subsequent opening of cylinder sucking transfer.
  • two-stroke engines make suction of fluid necessary to combustion by movement upward of the piston.
  • Method according to the invention permits increasing amount of sucked fluid.
  • the invention further relates to a two-stroke internal combustion engine as defined in independent claim 4.
  • suction valve 4 is obviously opened, in the embodiment shown a valve with a disc 13 rotating on relevant washer 11, while, during the following phase, piston 3 descents, rotating disc valve 4 is closed and fluid within carter-pump 5 is compressed.
