A two cycle internal combustion spark ignition engine is described comprising in combination: (a) minimum of two side by side spaced apart axially parallel cylinders, (b) a hollow guideway parallel to and positioned between the cylinders, (c) one variable volume combustion chamber, (d) air intake porting located in each cylinder wall at a first end of the combustion chamber, having an upstream end and a downstream end, (e) exhaust porting located in each cylinder wall at a second end of the combustion chamber. (f) means for delivering fuel into the cylinders approximately midway of the length of the combustion chamber, (g) at least one spark plug for igniting a mixture of fuel and air in the combustion chamber, (h) one cylindrical single headed pressure sealing valveless air intake controlling piston coaxial with and slidably mounted within each of the cylinders, and (i) a rigid non-pivotal bridging means spanning from piston axis to piston axis of the air intake controlling pistons.
