That 1992 Ranger, has a couple engine options. a 4 cylinder Diesel, a 4 cylinder DFI/SPI Gas engine, and a v-6 MPFI gas engine.
I hope that it has the 4 Cylinder DFI/SPI engine. this engine has 2 spark plugs per cylinder. you only need 1 plug per cylinder to make it work on Hydrogen, or gas vapor. the other plug can be removed and replace with a water injector to keep the combustion chamber cool for whatever purposes you have to keep it cool.
I never worry about cooling an engine, because of location on earth, a properly functioning cooling system will prevent the engine from freezing solid while driving on the highway. I have seen engine that were warmed up for 40 minutes prior to driving, so they were running for 40 minutes beforehand. then upon driving, the radiator froze solid, the engine severely overheated, and opening the hood revealed GLOWING HEADS and GLOWING EXHAUST MANIFOLDS. this engine was toast, and seized upon cooling off.
truck got sold 2 weeks later. point of the matter is cooling the combustion chamber like some claim is necessary is really a misnomer as a properly functioning cooling system will prevent freeze-up as well as overheating.
but also look at the second plug hole as something useful....like say a glass "fire-sight" where you can see the color of combustion....a digital combustion pressure readout....a pyrometer mounting in each cylinder....the list goes on for a long while. point is that the 4 cylinder engine has 8 plugs, 4 of which are not necessary for operation on vapor or hydrogen. this lead way to allow the use of individual cylinder data collection. I am not saying that it won't be expen$ive, but I do say that it would be worthwhile.
