An internal combustion engine (1010) having an adjustable compression ratio is disclosed. The engine (1010) includes a housing (1013), a piston assembly (1012) adjustably coupled to the housing (1013), and a cylinder reciprocatingly disposed within the housing (1010). The cylinder reciprocates relative to the piston assembly (1013) during operation of the engine (1010). The engine (1010) further includes a compression ratio adjust mechanism (1300) in communication with the piston assembly (1012). The compression ratio adjustment mechanism (1300) is adaptable to adjust the compression ratio of the engine (1010) during operation. In another aspect of the present invention, the engine (1010) includes an exhaust valve in fluid communication with the cylinder and a crankshaft (1016) coupled to the cylinder, wherein the crankshaft (1016) includes a lobe for actuating the exhaust valve (1052).
