Automotive Combution, energy and pressure relation

AI Thread Summary
The discussion revolves around calculating the force generated by burning fuel in a car simulation, focusing on variables like pressure, fuel amount, air (O2) amount, and temperature. Participants suggest that understanding engine temperature at idle and how it changes with fuel input is crucial for calculations. It is noted that the fuel supply is controlled by the engine's computer, complicating the relationship between fuel and engine performance. The conversation highlights the need for a simplified model to account for these variables, emphasizing that some factors may offset each other. Ultimately, the complexity of the system requires careful consideration of all interacting elements for accurate calculations.

Hello guys,

I'm currently working on a car simulation just for fun, but I'm stuck...

The force to move a car is generated by burning fuel ( to be more percise, diesel or gasolin).
But there are more variables:
Pressure (i know this because of turbos and such)
amount of fuel
amount of air (or O2)
temperature

is there a formula to calculate the force created, or released energy?
If there is, can you calculate the temperature of the engine too?

Thanks for reading and I hope you can answer some of my questions :)

Your question is very interesting! And there are many was to come apon a solution. first what is the normal temperature of the engine when it is idel (i english good) next, fint the increase in tempurature, this means taking temp of engine and making a inequality based on increase in fuel subtracted by the amount of h2o present in the engine.

i can't really follow you.
Let's taka a theoretical 100 degree Celcius is the idle temperature.

I just realize my whole idea of how the engine works is wrong, the amount of fuel isn't fixed (like i thought) it's controlled by the boardcomputer. I'll have to find that out too.. The airflow is regulated by the Gaspadel (correct me if I'm wrong). If this all is true than I have to many variabels and not enough data to do any calculations..
 
but remember that some operations do cancel each other our, so start with the minimum amount of fuel as related to temp
 
Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
TL;DR Summary: Heard in the news about using sonar to locate the sub Hello : After the sinking of the ship near the Greek shores , carrying of alot of people , there was another accident that include 5 tourists and a submarine visiting the titanic , which went missing Some technical notes captured my attention, that there us few sonar devices are hearing sounds repeated every 30 seconds , but they are not able to locate the source Is it possible that the sound waves are reflecting from...
