    摘要: A method of operating an engine for a vehicle having at least one cylinder and an exhaust passage communicatively coupled to the cylinder including at least one exhaust throttle disposed therein downstream of the cylinder, the method comprising of operating the cylinder to achieve controlled autoignition of an air and a fuel mixture within the cylinder, during a first transient condition, adjusting at least the exhaust throttle to maintain controlled autoignition within the cylinder, and during a second transient condition, adjusting at least an actuator other than the exhaust throttle to maintain controlled autoignition within the cylinder, where said first transient condition is of a shorter duration than said second transient condition.
