Title: Scavenging passage and intake passage of internal- combustion engine
Inventor: JIYO BANDOU
IPC: F02M29/06
Filed: 1982-10-07
Abstract: PURPOSE:To obtain better combustion by installing an eddy chamber on a part of a scavenging passage, which connects a crank chamber to the inside of a cylinder, thereby accelerating fuel evaporation and damping gas vibration. CONSTITUTION:When the gas in a crank chamber 2 is compressed as a piston goes down, scavenging air enters from the crank chamber 2 into a cylindrical eddy chamber 6, which is installed on a part of a connection passage 4, via the connection passage 4. At that time, since the connection passage 4 is placed a little off the cylinder axis, the scavenging air including liquid fuel is rotated at a high speed within the eddy chamber 6, resulting in accelerated evaporation of the liquid fuel. In addition, the location of an exit 7 of the eddy chamber 6 to a scavenging passage 8, which is led to the inside of a cylinder, is chosen in such a manner that the exit 7 projects inward from the wall of the eddy chamber 6 and besides scavenging air from the connection passage 4 does not directly reach the exit 7. As a result, in the eddy chamber 6, liquid component is rotated along the cylindrical wall, while gaseous component is rotated at the central part of the cylinder so that evaporated fuel can efficiently be supplied.
