Corning Inc. has a plant near here in Erwin, NY that make the substrates for the diesel catalytic converters. Clean diesels and clean 2 strokes are being built for a variety of applications. Check the EPA specifications for each class. GE has been working on converting diesel locomotive engines to natural gas. Bus fleets in northern Pennsylvania are using natural gas as well. There is a public natural gas fueling station in Sayre, PA.

As for cost of producing an engine there are several factors involved. Tooling, materials, and labor figure in along with the price-volume levels. Would the cost of complex dies for aluminum casting or cylinder wall coatings be more than an injector system? Only your engineers know for sure. The use of indirect injection may mitigate the need for a balance shaft at the price of a lower combustion ratio. It will be exciting to see what develops.
