FUEL INDUCTION TECHNIQUES FOR A HYDROGEN OPERATED ENGINE

It is practically impossible to replace the internal combustion engines which have already become an indispensable and integral part of our present day life style, particularly in the transportation and agricultural sectors. Unfortunately, the survival of these engines has, of late, been threatened by the dual problems of the fuel crisis and environmental pollution. Therefore, to sustain the present growth rate of civilization, a non-depletable, clean fuel must be expeditiously sought. Hydrogen exactly caters to these specified needs. Hydrogen, even though "renewable" and "clean-burning" it does give rise to some undesirable combustion problems in an engine operation, such as backfire, pre-ignition, knocking and rapid rate of pressure rise. It has been experimentally evaluated that the fuel induction technique (FIT) does play a very dominant role in obtaining smooth engine operation. This paper discusses such various possible modes. Research work carried out by different investigators has been highlighted. © 1990.
