ABSTRACT:
An improved combustion chamber configuration for a two-cycle engine that improves combustion and running at both idle and high speed. The combustion chamber comprises a first portion that communicates with a spark plug and has a relatively small volume. The first portion communicates with a second larger volume portion that has a decreasing cross-sectional area as approaching the exhaust port so as to insure complete flame propagation even at high engine speeds.
