Piston Slap: Depressurizing Compressed Air Engines?

Just saw your post about running out of questions. Just wanted to say that you have a fan in Montreal, Canada! Love the subjects you guys talk about!

Everyone is talking about electrification and hybridization, but battery cost is a big negative point. PSA (group Peugeot Citroen) has developed a hybrid air system using compressed air as an alternative to electricity. A very smart and cost effective system. Where is that system now?

Why are the manufacturers not using tech like this to reduce their fleet MPG?

  • ToolGuy This podcast was pretty interesting. I listened to it this morning, and now I am commenting. Listened to the podcast, now commenting on the podcast. See how this works? LOL.
  • VoGhost If you want this to succeed, enlarge the battery and make the vehicle in Spartanburg so you buyers get the $7,500 discount.
  • Jeff Look at the the 65 and 66 Pontiacs some of the most beautiful and well made Pontiacs. 66 Olds Toronado and 67 Cadillac Eldorado were beautiful as well. Mercury had some really nice looking cars during the 60s as well. The 69 thru 72 Grand Prix were nice along with the first generation of Monte Carlo 70 thru 72. Midsize GM cars were nice as well.The 69s were still good but the cheapening started in 68. Even the 70s GMs were good but fit and finish took a dive especially the interiors with more plastics and more shared interiors.
  • Proud2BUnion I typically recommend that no matter what make or model you purchase used, just assure that is HAS a prior salvage/rebuilt title. Best "Bang for your buck"!
  • Redapple2 jeffbut they dont want to ... their pick up is 4th behind ford/ram, Toyota. GM has the Best engineers in the world. More truck profit than the other 3. Silverado + Sierra+ Tahoe + Yukon sales = 2x ford total @ $15,000 profit per. Tons o $ to invest in the BEST truck. No. They make crap. Garbage. Evil gm Vampire
