Is that gasoline or natural gas or propane? It doesn't say in the article.

Industrial "gas engines" are generally natural gas. Cummins sells natural gas versions of many of their engines for compressor/pump drive, power generation, etc.

these are totally diffrent engines from the diesel version... these ones have spark plugs.

Those are LNG or CNG and even propane engine , can be found in any truck or buses , PG&E has many of them in the trucks , lot of your transit company are using them also... Westport is a canadian company that is running Cummins gas engine division. they have also developed a gas system where I have converted the ISX diesel engine to NG by using a injector that uses a diesel pilot to ignite the NG combustion , without the use of spark plugs , biggest problem was developing a pump to build up pressure to use for injection ,each proto type injector was insured for 15,000 apiece , with CNG it is easy , but storage is the drawback and require large amount of tank space, LNG is great , but LNG also store at minus 256 degrees , and require special tanks, last one I did the tanks cost was 12,000 dollars , the biggest drawback to the spark plugs engine is the maintainance , one spark plug cost over 30 dollars and that is the cheapest component on the engine , but they do run clean and the fuel is cheap,

Interesting...

They have new technology for converting natural gas to LNG and keeping it liquefied w/o high pressures or low temps. They're doing it that way because you can move a lot more through a pipeline and you can transport it by tanker or ship.

I wonder when that kind of technology will be adapted to fuel tanks for vehicles.

were already using that technology in trucks tank , there is no pressure in that fuel tank , we were using the pump to build LNG pressure up to 2500 psi for atomizing the fuel thru the injectors , and we also use the CAP pump from the ISC engine to get the diesel pilot pressure up to 2500 psi also. the reason we use the high pressure was , we eliminated the injector camshaft from the ISX and use electronic injectors .
