CNG CumminsLug_Nut, with a look at what’s coming.  In the near future your new Cummins powered coach may have spark plugs or like designed igniters.  It will also operate a whole lot cheaper.  It will be like lowering the price of diesel by $1.50 to $2.00 a gallon.  It will not need a DEF system that current produced large diesel engines require.  It sounds too good to be true?  Read on!

Cummins Westport has developed and tested a natural gas (CNG) powered engine using the current Cummins series diesel engine line up.   The ISL G, natural gas powered prime mover has been tested and run since 2007 with about 13,000 in operation today.  The ISX 12 G will be marketed to the trucking industry in 2013.  This engine size, the 11.9 liter, is the biggest selling over the road mill.  While both the ISL G and ISX 12 G will be available in North America in 2013, it is not clear if the “B” and “C” series will be.

One of the biggest issues currently is the availability of fueling stations throughout the country.  The majority of these are in southern California at this time, but that’s about to ramp up.  Until now, CNG powered vehicles were confined to urban areas where services were readily available. Some big name truck fueling stations, like the Flying J, have already installed the needed equipment and tanks at some locations, with more following.

Environmentally, this fuel burns green, with little to no pollutants.  However, there are concerns over the leakage of unburned gas.   That leakage of most concern is between the distribution network to the final end user.

CNG is the fastest growing alternate fuel in the world today with 20 million vehicles expected to be operating on it by 2016.  This clean burning fuel may be the answer, particularly for the heavy vehicle market, at least until a more efficient electrically powered system can be found.

So, watch for these new engines to hit the market in the trucking industry in 2013.  Will they be introduced in the RV sector in the near future?  I would imagine the RV builders would certainly get on board if at all possible.  They are constantly looking at ways to improve their products and attract new buyers.  A less costly fuel alternative would go a long way in doing just that.  Can current engines be converted from diesel to CNG?  Unfortunately, they cannot.  These units are specifically designed and built by Cummins Westport.

Would you consider trading up to a new rig if these engines were available?  Let’s hear from you in the comments section below.
