Abstract
According to the present invention a closed cell compressible sponge is used to provide a seal between the cylinder head assembly and the crankcase assembly in variable compression ratio engines. The closed cell sponge is capable of accommodating large travel distances and can be fabricated out of durable rubber. The sponge gasket also does not flap, and is effective at isolating noise inside the crankcase.
