“the apex of internal combustion engines means they’re doing more than just propelling a vehicle around roads and highways. They’d also be air purifiers, removing CO2 as they go.”
which sounds amazing, but is followed by 0 facts or information on how that might work.
- shmeeed 7mo agoThis is annoying marketing bs that the motor press has been touting for decades with every new generation of efficient engines. An ICE (that's not running on H2) always generates CO2. If it did the reverse, it would be a Fischer-Tropsch reactor. /s
- testing22321 7mo agoI believe there are quite a few Volvos that, when used in dense urban environments, emit cleaner air from the exhaust than they ingest. https://www.volvocarsmississauga.com/en/news/view/how-does-the-2025-volvo-ex40-s-air-purification-system-work-in-city-traffic-/143404#:~:text=You%20can%20schedule%20pre%2Dcleaning,You%20Monitor%20Air%20Quality%20Levels? https://www.volvocarsmississauga.com/en/news/view/how-does-t...
- shmeeed 7mo agoI'm sure they love people believing that, but it's a cabin air purification system, and it's about PM 2.5 particles, not CO2. There was a dutch EV prototype a few years ago that did include an active CO2 capture system as a proof of concept.
- linksnapzz 7mo agoAt operating temperatures, a modern ICE w/ a 3-way catalytic converter driving at highway speeds through the right environment (L.A. on a bad smog day) could easily have NOx and VOC levels at the tailpipe that are lower than what's going into the intake manifold.
- 7v3x3n3sem9vv 7mo agothis is literally how Ford marketed their PZEV (practically zero emissions vehicle) cars around 2003. https://www.latimes.com/archives/la-xpm-2004-jun-09-hy-neil9-story.html#:~:text=PZEV%20vehicles%20actually%20pollute%20less,air%20sucked%20into%20the%20engine. https://www.latimes.com/archives/la-xpm-2004-jun-09-hy-neil9...
- shmeeed 7mo agoThat's true, and has been for quite some time. Still: NOx and VOC, but not CO2.
- advisedwang 7mo agoThey are putting Carbon Capture into some concept cars and a race car [1]. Some more info in the system at [2]. I don't see any benefit for this technology being in a car vs at a stationary large scale facility.
