Definitions

  • the invention relates to a reciprocating internal combustion engine with at least two master cylinders, which have inlet valves and are connected via intermediate valves to a common secondary cylinder, which works in a two-stroke cycle and alternately in one cycle, the post-expansion of the exhaust gases of the two master cylinders and in the subsequent stroke of the displacement of the exhaust gas serves at least one outlet valve provided on it, and has a multiple of the volume of a master cylinder.
  • the above-mentioned principles of construction of the internal combustion engine according to the invention enable the combustion in the main cylinders (during the pre-expansion cycle, which corresponds to the work cycle of the usual four-cycle cycle after the intake cycle and after the compression cycle) to be carried out with a lack of oxygen and in the secondary cylinder to carry out a combustion with a lack of oxygen and in a combustion with an excess of oxygen (during the post-expansion cycle) can be carried out in the secondary cylinder.
  • the lack of oxygen in the combustion in the main cylinders which takes place at a high temperature level, minimizes the oxidation of the nitrogen in the air.
  • the secondary cylinder is charged with fresh air up to the pressure prevailing in the master cylinder at the end of the pre-expansion cycle. This prevents pressure losses at the beginning of the post-expansion cycle.
  • the intermediate flushing with air in the fifth and sixth cycle of the master cylinder reduces the cooling losses.
  • the afterburning and post-expansion in the secondary cylinder reduces the exhaust gas losses.
  • the primary energy consumption of the motor according to the invention is therefore significantly reduced and the conversion efficiency from chemical to mechanical energy is increased.
  • the construction principles of the internal combustion engine according to the invention also enable that shortly before the end of the post-expansion cycle, all cylinders can be connected via the intermediate valves for exhaust gas recirculation from the one master cylinder at the end of the post-expansion cycle to the other master cylinder at the end of the first intake cycle, the exhaust gas recirculation being effective Suction volume * of the master cylinder is adjustable. This makes it possible to control the torque with minimized nitrogen oxide and carbon monoxide emissions.
  • crankshafts of the master cylinder and the secondary cylinder are advantageously connected via a 2 to 3 gear mechanism.
  • the two master cylinders HZ1 and HZ2 are connected to a common secondary cylinder NZ via intermediate valves ZV1 and ZV2 provided on them.
  • the secondary cylinder NZ has an exhaust valve AV common to the entire system of cylinders HZ1, HZ2 and NZ. Its volume is three to four times the volume of a master cylinder HZ1 or HZ2.
  • the secondary cylinder NZ works on its own crankshaft NK, which is connected to the crankshafts K1 and K2 of the master cylinders HZ1 and HZ2 via a gearbox G.
  • FIGS. 3.1 to 3.8 show the piston and valve positions of the master cylinders HZ1 and HZ2 and of the secondary cylinder NZ at selected times, as denoted by 1 to 8 in the time axis t of FIG.
