    摘要： A method for a hydrogen fueled internal combustion engine to reduce backfiring, pre-ignition, and/or backflash, the engine also including a combustion chamber, an intake manifold, an exhaust manifold, at least one intake valve, at least one exhaust valve, a hydrogen injector, a compression device, and a variable valve timing system coupled to the intake valves. The method comprises compressing air using the compression device; injecting hydrogen and mixing at least said hydrogen with air discharged from the compression device; and opening the intake valve to induct at least air into the combustion chamber, wherein the intake valve opening time varies with an operating condition.

    摘要： An intake and exhaust system for a dual mode HCCI engine, which provides superior intake temperature control and homogeneity for engine operation in SI and HCCI modes, as well as during transition between SI and HCCI modes and vice-versa. The system includes adjusted intake cam movement event lengths for intake valve operation at specified modes of operation. The system further includes at least one cam profile switching device operatively connected to intake and exhaust valves in an engine for controlling event length, maximum lift, and valve opening/closing timings for the intake and exhaust valves. The system yet further includes a bifurcated intake system and camless valve actuators for controlling intake valves for facilitating operation in SI or HCCI modes, as well as transition between SI and HCCI modes and vice-versa.

    摘要： A system and method for implementing clustered network file system lock management is provided. A failure of a first server node among a collection of nodes is detected. The first server node includes lock status data. The lock status data grants a first client exclusive access to data stored on a server storage device. The server storage device is coupled to the collection of server nodes. The lock status data is transferred to a second server node among the collection of server nodes. The first client is granted exclusive access to data stored on the server storage device, based on the lock status data transferred to the second server node from the first server node, in response to the transferring. Lock requests from the collection of clients are accepted, in response to the transferring.
