Hi dvdw, Stoichiometric engines with oxygen sensors and exhaust gas recirculation for Nox emission reduction has been around since approximately 1980. The shuttles from Detroit airport to Detroit have run CNG for decades. Big HD truck OEM's are designing natural gas engines for over the road application. The most restrictive part of natural gas gaining utilization is the supply infrastructure. Entergy ran a natural gas fleet back in the mid 1990's. They were leased and bought back by GM. The problem was high pressure tanks had durability issues after being driven thousands of miles. Entergy loved the fleet. GM recalled them after an employee almost had his knee taken off while refueling . The end cap of the fuel tank loosened from its fiberglass center section and came out from under the truck's framewell. I knew the regional commercial manager who delivered the check when they were repurchased. It seems it should be a faster transition, but infrastructure install seems slow. My expartner in the Chevy store has a very large Volvo,Mack, Kenworth franchise organization. All of the HD OEM manufacturers want their in house design. It prevents others from getting into their parts supply chain. Currently older designs are so available - there is a cottage industry of remanufactured components displacing OEM parts purchases. This competition has been somewhat blunted with (along with software packages that control horse power and emissions). In many cases the difference between a 15 horse power diesel engine and a 175 horse power diesel engine is how much you pay for it. All of the hard metal pieces are the same - amazing technology.
