  • Patent number: 9038579
    Abstract: The present invention relates to a fuel cell-engine hybrid system formed to effectively utilize an exhaust gas discharged from a process for generating electricity. A fuel cell-engine hybrid system according to the present invention includes: an electricity generating unit including a cathode and an anode interposing an electrolyte membrane therebetween; and an engine unit connected to a rear end of the electricity generating unit and generating power by receiving the exhaust gas discharged from the anode.
    Type: Grant

  • Publication number: 20090048756
    Abstract: In a multi-mode, 2-stroke/4-stroke internal combustion engine operation, by switching the engine stroke from 4-stroke operation to 2-stroke operation so that the combustion frequency is doubled, doubling of the engine power is achieved even at the same work output per cycle. In order to meet the demand of extremely high power, the engine operates in 4-stroke boosted SI operation transitioned from 2-stroke HCCI operation at pre-set level of power and crank speed requirements. By combining the multi-stroke (2-stroke HCCI and 4-stroke HCCI) and multi-mode operation (2-stroke HCCI and 4-stroke boosted SI operation), full load range and overall high efficiency with minimal NOx emission are achieved.
