Title:
TWO-CYCLE ENGINE
Document Type and Number:
WIPO Patent Application WO/2007/004641
Kind Code:
A1
Abstract:
A two-cycle engine in which reductions in size and pollution are promoted. The
two-cycle engine comprises a cylinder containing a piston so as to be able to reciprocate,
a scavenging gas storage chamber covering the lower opening of the cylinder under
an enclosed state, an intake section provided in the scavenging gas storage chamber,
a scavenging channel allowing the scavenging gas storage chamber to communicate
with the cylinder, a connecting rod coupled with the piston and penetrating the
scavenging gas storage chamber, a crank mechanism for reciprocating the connecting
rod linearly, and a seal portion arranged in an insertion hole for passing the
connecting rod in the scavenging gas storage chamber and sealing the scavenging
gas storage chamber hermetically while allowing linear reciprocation of the
connecting rod. The intake section has a structure for taking outside air into
the scavenging gas storage chamber and may be provided with a mechanism for spraying
fuel onto a cylinder head.
