ABSTRACT:
A variable compression ratio, direct injection engine. A rotatable collar in operative engagement with a cylinder liner holder assembly is utilized to raise and lower the cylinder liner relative to the crankshaft, thereby varying the compression ratio. A double chain drive mechanism maintains a constant valve timing relationship as the cylinder liner is raised and lowered. The head assembly is provided with a removable fire deck and a tapered intake port.
