<p>A dynamic gas seal for an internal combustion engine reduces exhaust emissions by minimizing the amount of hydrocarbon-laden air from the engine breather (36) that enters the combustion chamber (24) through the open intake valve (22). The dynamic gas seal includes several channels (34, 16a, 16b) which allow filtered air at atmospheric pressure to enter the combustion chamber (24) in place of oil-laden air from the breather. The dynamic gas seal includes a channel between the air filter and the intake valve system, and channels between the breather exit and the carburetor intake.</p> |
