    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.

    摘要: Fuel cell systems (100, 400) and related methods involving accumulators (106, 200, 300, 406) with multiple regions (R1, R2; R1′, R2′) of differing water fill rates are provided. At least one accumulator region with a relatively more-rapid fill rate (R2; R2′) than another accumulator region (R1; R1′) is drained of water at shutdown under freezing conditions to allow at least that region to be free of water and ice. That region is then available to receive water from and supply water to, a fuel cell (102; 402) nominally upon start-up. The region having the relatively more-rapid fill rate (R2; R2′) may typically be of relatively lesser volume, and may be positioned either relatively below or relatively above the other region(s).
