TWO-STROKE ENGINE

摘要

A two-stroke engine working on the Miller/Atkinson cycle, wherein a space underside the piston crown is divided by a separator into two complimentary sections communicating with each other through a passage controlled by a valve so that the engine avoids the subpressure under the piston crown.

主权项

1. A two-stroke reciprocating internal combustion engine comprising at least:
a cylinder; a piston slidably fitted in said cylinder, said piston sealing one side of a combustion chamber defined by said piston and said cylinder, said piston having a first end adjacent said combustion chamber and a second opposite end; a space defined between said first end and said second end, said space being divided, by a separator, into a first section, defined between said first end and said separator, and a second section defined between said second end and said separator, said separator comprising a passage and a valve controlling said passage, so that the reciprocation of the piston varies the volume of the combustion chamber, the volume of the first section and the volume of the second section, and the communication of the first section with the second section is controlled by the valve.
