Abstract
A catalytic fuel igniter is compatible with internal combustion engines and other chemical fuel operated systems. The catalytic fuel igniter does not require electrical components typically required for such systems, thus reducing complexity. The catalytic fuel igniter includes a catalyst in a controlled environment which ignites the fuel and air at the proper time for engine operation. In one embodiment the fuel is a hydrogen fuel and the catalytic fuel igniter is a hydrogen fuel igniter.
Claims12
A catalytic fuel igniter comprising:
- a female fitting including an interior passage substantially therethrough;
- an open end of the interior passage;
- a closed end of the interior passage opposite the open end;
- at least one slit through the closed end of the interior passage;
- a male fitting engagable with the female fitting to close the open end of the interior passage of the female fitting;
- and
- a catalytic plug residing in the interior passage at the closed end and in fluid communication with an exterior of the catalytic fuel igniter through the at least one slit,
- wherein the catalytic plug is made using the process:
- washing porous white alumina with distilled water;
- drying the washed alumina with hydrogen gas flame;
- saturating the dried alumina with two drops of concentrated Chloroplatinic acid;
- reducing with excess 5-7 mL diluted Sodium Hydroxymethane Sulfinate solution heated to at least 78° Celsius to make platinized alumina;
- drying the platinized alumina using a hydrogen flame;
- placing one drop of concentrated Chloroplatinic acid on the platinized alumina;
- decomposing with hydrogen flame until visible silver platinum is deposited in the pores;
- and
- bringing the alumina catalyst to room temperature and introduce hydrogen gas to re-generate the catalyst.
