Definitions

  • the main characteristic of this engine consists in its being able to operate in a single cycle of only two-stroke phases and with only the exhaust valve.
  • the single-stage or two-stage screw compressor assembly - 1 - has been considered, with a transmission ratio, with respect to the driving pulley of the engine shaft and pulling; such as to enable, also by means of the tank - 2 - necessary for a fast start of the engine and for accumulating pressurized air and regulating its delivery, so as to meet the various demands for pressure and volume of air at low and medium r.p.m.
  • turbosuperchargers in series - 3 - or a two-stage supercharger.
  • the pneumatic system in two-stroke or four-stroke engines equipped with compressed-air injectors comprises also an air intake - 4 - necessary for exploiting the pressure exerted by the atmospheric air after a given speed, conveying it to a choke tube, so as to inject it already with a certain pressure, into the turbosuperchargers, thus improving the efficiency and cooling thereof.
  • Other components of the pneumatic transmission are: the non-return valve - 5 -, the air filters - 6 -, the condensate trap - 7 -, the air-inflow regulation valve - a -, some metres of compressed-air piping - 9 -, and possible other items.
  • each cylinder of a compressed-air injector enables an increase in efficiency and power in any type of internal combustion engine provided with a compressor with or without tank, or equipped even only with a turbosupercharger or turbointercooler.
  • a further improvement in the efficiency and power of the engine is obtained during supercharging effected directly by the injector by eliminating the significant pressure losses and other losses due to friction in the intake pipes and in the intersection with the suction valve.
  • the two-stroke twin-injector-per-cylinder engine differs from the traditional four-stroke engine in the following mechanical members:
