Abstract

Обычный бензиновый двигатель модифицируют для работы в качестве двухтопливного двигателя, калибруют для сжигания газообразного водорода в качестве основного топлива и бензина в качестве дополнительного топлива при различных допустимых значениях λ, предотвращая появление неприемлемых λ. При сжигании водорода двигатель работает предпочтительно в режиме с наддувом и в режиме с обедненной смесью с некоторыми допустимыми соотношениями воздух/топливо, при которых имеют место только сравнительно небольшие выбросы NO. Когда необходимо увеличение мощности или ускорение, контролируемые процессором инжекторы топлива впрыскивают сравнительно небольшое количество бензина в двигатель, что дает топливную смесь, препятствующую увеличению выбросов NO, поскольку процессор управляет двигателем так, что двигатель работает при стехиометрическом соотношении воздух/топливо, причем каталитический нейтрализатор наилучшим образом уменьшает вредные выбросы в атмосферу. Впрыск дополнительного жидкого бензинового топлива к газообразному водородному топливу выполняют так, что температура значительно снижает или полностью исключает склонность двигателя к обратной вспышке. Двигатель также имеет средства безопасности, заключающиеся в том, что при обнаружении утечки водорода подачу водорода в качестве топлива полностью отключают. В этом случае двигатель работает на бензине, как на резервном топливе.
