Abstract
A spark ignited engine of the type employing exhaust gas recirculation and stratification of the recirculated exhaust gas. The engine has at least one cylinder accommodating a piston and communicating with at least one inlet port cooperating with an inlet valve for inducing air into the cylinder, and at least one exhaust port cooperating with an exhaust valve for discharging exhaust gas from the cylinder. The engine is operated such that the recirculated exhaust gas is induced alone into the cylinder through the inlet port during a part of the engine operating time whereby recirculated exhaust gas and air are introduced through the same port, though at different times.
