Internal combustion engines $($ICE$)$ are a special class of reactors. There are a large

number of ICE. In this question, we ask you to go a little bit deep into the subject.

a$)$ List as many types of ICE as possible.

b$)$ What is the fuel?

c$)$ What is the "advertised" engine efficiency? Why are some of the engines more

efficient than the others?

d$)$ Can you model the ICE as one or more of ideal reactors? Prepare a table with the

information you gathered so far, and also list whether the ICE can be classified as a

BR$,$ a PFR$,$ or a CSTR$.$

e$)$ Choose one of them and describe the features as a chemical reactor. Is it isothermal,

adiabatic? Is it constant volume, constant pressure? Is it an open system or a closed

system?

f$)$ What can you say about the $C{O}_2$ footprint of an ICE operation?
