1. An internal combustion engine comprising:
a first piston reciprocatingly disposed in a first cylinder;
a second piston reciprocatingly disposed in a second cylinder;
a crankshaft coupled with the first piston and the second piston for rotational motion associated with reciprocating movement of at least one of the first piston and the second piston;
a combustion chamber fluidly coupled with the first cylinder and the second cylinder to continuously define a fluid volume including the combustion chamber, the first cylinder, and the second cylinder;
an ignition source at least partially disposed within the combustion chamber;
an intake valve providing selective fluid communication between an intake system and the combustion chamber; and
an exhaust valve providing selective fluid communication between an exhaust system and the combustion chamber;
wherein a centerline between the intake valve and the exhaust valve is generally centered between the first cylinder and the second cylinder.
