Title: Fuel injection type two cycle engine
Inventor: KATO TAKASUKE
IPC: F02M61/14
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To promote the mixture of fuel and air so as to obtain uniform air- fuel mixture stably. SOLUTION: Each scavenging passage 16 to 18 is formed in the direction in which the central line thereof forms a tangent line for a circle centered on an axial line L of a cylinder when viewed from the direction of the axial line L of the cylinder, and scavenging air which flows into the cylinder 4 from each scavenging port 16a to 18a forms a swirl in the same rotation direction centered on the axial line L of the cylinder. Consequently, fuel jetted into the cylinder 4 by an injector 22 is mixed with scavenging air (new air) which generates the swirl in the same rotation direction in the cylinder 4 sufficiently, forming uniform air-fuel mixture.
