Optimizing the Shape of a Compression-Ignition Engine Combustion Chamber by Using Simulation Tests

Polish Maritime Research, 2019
Modern solutions used in compression-ignition internal combustion engines are quite similar to each other. The use of high-pressure, direct fuel injection results in high combustion rates with controlled exhaust emissions.

Bayesian models for the determination of resonant frequencies in a DI diesel engine [PDF]

, 2011
A time series method for the determination of combustion chamber resonant frequencies is outlined. This technique employs the use of Markov-chain Monte Carlo (MCMC) to infer parameters in a chosen model of the data.
