A few years ago I created a Cranking In-Cylinder Waveform Generator – which, using some math and physics, allowed to plot a waveform for a cranking in-cylinder test. The engine could be “broken” in various ways, such as valve leaks, ring leaks, camshaft timing being off, etc.
I have now updated the generator. Firstly, two plots are generated at the same time, allowing comparisons to a “good” cylinder, or comparisons of two different failures. Secondly, experimental features such as specifying vacuum at the intake manifold, or extra pressure at the exhaust manifold, have been added.
