Thanks, guys, Keith, I listened to the aftertreatment podcast at SWRI, sent a follow-up message to Chris Sharp who is in charge of their work.

Hey, Lou, thanks for the note and the numbers. If you get back to me on this, I wonder if you have any references I could look up? /Ernie

Thanks, Tugboad, that is a very helpful question. As I see it, high power and high efficiency mean high pressure, and with that comes NOx. A cargo ship engine running on ammonia might be an exception to the rule, but today I am just looking at diesel fuel. I am thinking of large engines that...

What is the maximum pressure that a person should design for in a diesel engine cycle (normal operation)? If the answer is different according to size or type of service, All kinds are of interest Is 22 MPa (3200 psi) too high? Too low? References are appreciated. I thought I remembered an...

Can lithium batteries power all cars in America? The answer may be “Yes,” but we must change direction if we are to have any chance. Based on recent history, after the coronavirus pandemic is over, US new car sales will return to about 17.5 million units per year. When we get to a first year...

Thank you, RodRico, I see you are ahead of me with your program. I have an air standard model with variable specific heat ratio, but no rational modeling of losses. We have both an analytical model and a finite element one. The finite element model can be extended to include losses, and...

Could someone recommend freeware or a program of modest cost for evaluating engine performance? (Thermodynamics with heat transfer and friction?) I can't afford GE Power. I am trying to model a CI two-stroke.
