An internal combustion engine may include at least one cylinder, a first outlet valve and a second outlet valve for directing exhaust gas out from a combustion chamber of the at least one cylinder. The first outlet valve may include a first valve opening and a first valve body where the first valve opening is adjustable between a closed position and an open position. The second outlet valve may include a second valve opening and a second valve body where the second valve body is adjustable between a closed position and an open position. An adjusting lever may adjust one or both of the first valve body and the second valve body between the open position and the closed position.

An interposed coaxial valve system designed for internal combustion engines. The system comprises a single main valve integrating two coaxial valves: an interior valve and an exterior valve. The interior valve may move independently from the exterior valve during engine operation. The system minimizes spatial occupancy for internal combustion engine valves. By interposing the interior valve within the exterior valve, the system achieves a compact and efficient design. The system may also comprise adjacent intake and exhaust ports to promote heat transfer between the two ports.
