i would like to know the horse power achieved by using CNG as a fuel for diesel locos.one doubt is that like in cars CNG usage can cause low acceleration of the diesel locos also? if so, it is not useful for running fast passenger trains.waiting for your reply

These are the folks who did the BNSF conversion:

http://www.energyconversions.com/pubs.htm#sourcebook

They also offer commercial conversions for a variety of diesels to CNG / diesel bifuel.

Of course, there is also GE as listed in the original article as a provider of completed train engines.

Oh, and power output with their conversion is unchanged. You get full power. They do low pressure CNG injection after the valves have closed, so no loss of power. Fumigation of CNG into the air intake ahead of the valves displaces some air, so you get get a minor reduction in power with fumigation systems. Use of injection (high or low pressure) preserves full power and reduces CO and HC emissions.

And of course if you shut off the CNG, you get 100% power on straight diesel oil too.

We are reputed CNG consultants in Egypt. We would like to know more about Railway engines of about 3000 to 4000 hp using CNG for locomotive application.
