james j neiweem Posted June 25, 2014 Share Posted June 25, 2014 I read that CR England has added 10 Mack LNG pinnacles to their fleet in California. I don't think CR has had Macks since the Cruiseliner and F model days. Quote Link to comment https://www.bigmacktrucks.com/topic/36147-mack-lng/ Share on other sites More sharing options...
Mackpro Posted June 26, 2014 Share Posted June 26, 2014 I see the UPS natural gas CXU's through here all the time. They seem happy with them. We just sent a guy to school on them. Cummins sure has the market cornered on the class 8 engines for now. Our Tech that went to school on them says the Mack MP natural gas engine is being tested now however its a hybrid and runs on diesel and naural gas both Quote Link to comment https://www.bigmacktrucks.com/topic/36147-mack-lng/#findComment-250600 Share on other sites More sharing options...
bbigrig Posted June 27, 2014 Share Posted June 27, 2014 Westport, Cummins former partner in NG engine development liked the Diesel ignited NG engine design against the spark ignited versions like Cummins uses.Only issue is the Diesel/NG engines I've seen has an SCR system to compensate for the Diesel. Seems a waste.I hear Westport will be teaming with Volvo instead of Cummins now. They are interested in the D13 and have given up on the ISX15.If you ever see the test unit have a look to see if it has Westport's name on it anywhere.

kscarbel2 Posted June 27, 2014 Share Posted June 27, 2014 These Pinnacles all have 11.9-liter Cummins-Westport ISX12 G natural gas engines.And they're putting 8.9-liter Cummins-Westport ISLs in the refuse trucks.

And yes, he said its downfall is that it will have SCR on it. Cumins/Westport looks like the way to go for now. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/36147-mack-lng/#findComment-251124 Share on other sites More sharing options...
