The link above takes you to a site I have found to be very helpful in my studies of the Otto cycle, but on this particular page, it depicts an equation for the rate of change of cylinder Pressure vs. crank angle, and in this particular equation, cylinder pressure itself is also a variable... or is it? They say that this equation will effectively solve the equation for cylinder pressure vs crank angle, but the first thing that perplexed me was that cylinder pressure was a variable in its own derivative, and second, how would someone go about deriving an actual equation for cylinder pressure vs crank angle from this?
