Analog Computation of Pressure Evolution in Internal Combustion Engines 720029
A philosophy is proposed that there might exist a definite correlation between the engine parameter variations and the Fourier coefficients of different harmonics of the corresponding pressure diagrams and their derivatives. It is thus possible to establish the law of variation of Fourier coefficients with respect to a particular parameter. From these correlations, it is possible to predict a cycle, taking into consideration all the important parameters-injection timing, load, speed, flow processes, etc.
Harmonic analyses developed in our laboratory are based on the principles of analog computation, to get results instantaneously, while the engine is running on the test bed.
