TLDR
In this paper, an indirect measurement of the cylinder pressure from diesel engines is demonstrated for a large two-stroke marine diesel engine and a small four-stroke diesel engine, which involves reconstructing the cylinder crank angle domain diagram from the acoustic emission generated during the combustion phase.About:

Challenges and obstacles in the application of acoustic emission to process machinery
TL;DR: In this paper, acoustic emission testing for faults in static equipment has been used since the 1970s, but its use as a monitoring technology for various machinery conditions has been poorly adopted by industry, despite a significant volume of work having been published over the past twenty years describing success in detecting rotating and reciprocating machinery faults.

Engine cylinder pressure reconstruction using crank kinematics and recurrently-trained neural networks
TL;DR: In this paper, a recurrent nonlinear autoregressive with exogenous input (NARX) neural network is proposed, and a suitable fully-recurrent training methodology is adapted and tuned, for reconstructing cylinder pressure in multi-cylinder IC engines using measured crank kinematics.
