  1.  @piccalillipit9211 , Wrong. A failed EGR will not leave you stranded. In fact, you won’t even notice that it failed until you get a smog check.

  2.  @jonathanshaw8868 , Well, I don’t know anything about EGRs on semis. I only know about every car I’ve had that had an EGR which were gas, not diesel.

  3.  @libtrs838 , No oxygen? The EGR doesn’t replace all the air with exhaust. It only replaces some, and when it does, the carburetor or fuel injectors will provide less fuel, so the air fuel ratio will remain correct. The goal is to reduce the combustion temperatures, which reduces NOX production.

  4.  @levilastun829 , Makes sense.

  5.  @reginaldbowls7180 , That’s what I thought.

  6.  @evanhandelong7685 , Wrong. The EGR doesn’t change the air fuel ratio. Exhaust isn’t air. It contains no oxygen.

  7.  @pardalbartz , Both of your statements are correct. Your EGR shouldn’t be stuck, and your heat exchanger shouldn’t have a leak. If either of those happen, you should fix it. What’s your point?

  8.  @Stevo2140 , Coolant? Do you have a blown head gasket or something?

  9.  @pardalbartz , A warning buzzer for low coolant, low oil, and too hot coolant should be mandatory on all vehicles. I agree with you 100%.

  10.  @jonathanshaw8868 , @piccalillipit9211, who I responded to, is talking about cars, not semis.

  11.  floridaman5125 , Mercedes are garbage. Buy a Toyota.

  13.  @j-coldho1164 , Why did your car overheat?

  14. Counter rotating gyros are not easier to turn than a single gyro, but they turn in strange perpendicular directions when you turn them.

  15. This engine has to be supercharged because it’s a two stroke without using the crankcase to pre-compress the intake. It therefore needs the supercharger to do it. It might work with a turbocharger. It should probably use a turbo/supercharger that’s driven by both a belt and the exhaust to improve efficiency.

  16. EVs aren’t around the corner. They’re already here. Level 3 chargers are dumb. You need to charge your EV at home. At home, overnight, they can charge slowly, and nearly every night. That means that most of the time for most people they’ll only have to charge 20-40 miles per night. That’s only about $1 - $2 worth of electricity per night, which can easily be installed in every parking space everywhere.

  17. Your calculations regarding the CO2 emissions of electric vs. fossil fuel is way off.

  18. I believe it should work. You need to add the springs for the vanes. If the slots are curved like the vanes, a straight flat rod of spring steel should work. Just slide it into the slot behind the vanes.

  19. How smooth is the inside of the 3D printed housing? Can you try using a compression tester to test the compression? If it’s leaking too much so there’s no compression, you’ll have to fix that.

  20. You could make the inside smooth with a steel sleeve. Just press it into the cylinder. It needs to be made of the right material that’s hard and compatible with the material used for the vanes.

  21. Being less efficient at low RPM and power output can be dealt with by turning it off and only running out when high RPM and power are required. This means it’s perfect for a hybrid vehicle. It would also be good for a home power backup system with a battery. It could recharge the battery whenever it’s low.

  22. The displacement and complexity of the engine are irrelevant. It’s the power to weight ratio and reliability that matter.

  23. Wrong. My 1998 Lexus LS400 has variable valve timing.
