摘要： An exhaust throttling system for engines having individual cylinders with at least one exhaust port to exhaust combustion gases from the cylinder chamber, the system including at least one sleeve configured to be slidably attached to the cylinder and selectively cover and uncover the exhaust port, the at least one sleeve formed of a metal having a coefficient of thermal expansion greater than the coefficient of thermal expansion of the cylinder to expand and contract in response to changes in temperature and change dimension of a gap between the at least one sleeve and the cylinder to change the rate of blowby of exhaust gases.
