Around the Horn Posted May 14, 2013 Share #1 Posted May 14, 2013 I am simply asking is it possible and/or practical to create a CNG-Hybrid bus?My younger brother asked me and I just didnt know the answer and also wanted to know as well. Link to comment Share on other sites More sharing options...
Fresh Pond Posted May 14, 2013 Share #2 Posted May 14, 2013 Arlington Transit (ART) recently brought these. DesignLine CNG Hybrid. Works in the same way as a conventional diesel-electric hybrid bus, but with CNG instead Link to comment Share on other sites More sharing options...
XcelsiorBoii4888 Posted May 14, 2013 Share #3 Posted May 14, 2013 If New Flyer created a CNG-Hybrid lets say a New Flyer CNG-Hybrd Xcelsior...would it be called... New Flyer "XNE40" Xcelsior? Link to comment Share on other sites More sharing options...
mtattrain Posted May 14, 2013 Share #4 Posted May 14, 2013 Possibru: "CNG Hybrid" can be seen near the rear of the bus, and this model is called the "BlueCity," a hybrid version of Hyundai's transit bus.

Culver Posted May 14, 2013 Share #5 Posted May 14, 2013 They have some CNG hybrids out in Cali. Forgot the agency, but there are some gas hybrids and some CNG hybrids out there. Link to comment Share on other sites More sharing options...
Cait Sith Posted May 14, 2013 Share #6 Posted May 14, 2013 San Diego MTS has a few This being one I believe Link to comment Share on other sites More sharing options...
QM1to6Ave Posted May 14, 2013 Share #7 Posted May 14, 2013 Where do they store the batteries on these things? Seems like the whole roof is taken up by the CNG tanks Link to comment Share on other sites More sharing options...
R32sdabest Posted May 14, 2013 Share #8 Posted May 14, 2013 I thought there were only diesel hybrid electric. This seems interesting Link to comment Share on other sites More sharing options...
Culver Posted May 14, 2013 Share #9 Posted May 14, 2013 Where do they store the batteries on these things? Seems like the whole roof is taken up by the CNG tanks I'd guess front 2 partitions of rooftop cover are CNG and back partition is batteries.

QM1to6Ave Posted May 14, 2013 Share #10 Posted May 14, 2013 I'd guess front 2 partitions of rooftop cover are CNG and back partition is batteries. ahh. Seems like a dangerous combo to me, but ok Link to comment Share on other sites More sharing options...
Culver Posted May 14, 2013 Share #11 Posted May 14, 2013 ahh. Seems like a dangerous combo to me, but ok I'm just guessing there. Reason I assumed so is the three partitions on the rooftop opposed to two on a regular CNG bus. Link to comment Share on other sites More sharing options...
SevenEleven Posted May 14, 2013 Share #12 Posted May 14, 2013 Translink had some: Hydrogen/CNG mashup. Link to comment Share on other sites More sharing options...
Blitz Posted May 14, 2013 Share #13 Posted May 14, 2013 ahh. Seems like a dangerous combo to me, but ok One of the reasons you will never see them in this city. Another reason being that these things are probably extremely expensive, both to purchase and to maintain. I also believe (just speculating based off of my knowledge of CNG and diesel electric buses) that the extreme heat generated by the CNG engine will cut the life of the hybrid components substantially.

Fresh Pond Posted May 14, 2013 Share #15 Posted May 14, 2013 Didn't the mta or the private lines experement with multiple fuels a while back? The only ones I know of was methanol and the original CNG test fleet Link to comment Share on other sites More sharing options...

aemoreira81 Posted May 19, 2013 Share #17 Posted May 19, 2013 This falls under the idea of just because you can make it, doesn't mean that you should. You already have 2 components with definite lifespan limits on the bus (the CNG tanks, usually certified for 15 or 20 years) and the batteries, which generally are for about 8 years or so. Plus, the sheer weight reduces the overall passenger capacity of the bus. (NJT's D4000 hybrids can only have 8 standees and NJT's 102D3 CNGs have a standing capacity of only 4 because of that).
