Scientific Design of Exhaust and Intake Systems (Engineering and Performance)

Good info

Apparently this is standard reading for anyone interested in internal combustion technology, whether that is hot-rodders, motorcycle customizers, etc. Most of the information has been established for decades, but then IC engines have been around awhile, and there aren't many mysteries left. This is good, applicable information, that works just as well now as it did in the '50s. I found it informative, and came away with a better understanding of things such as exhaust reversion and scavenging, Helmholtz resonance, and all the other fun stuff involved in making an engine breathe properly.

Very nice condition and fast shipping!

Older book but very helpful with my position as the engine lead engineer for my schools FSAE team.

I was studying the behavior of the air in Otto cycle engines and this book help to understand it. There is more than I expected, for example, emissions.

I bought this book to try to learn some basic principles about designing my own exhaust system. As an RF engineer, the principles were very similar and I did get some good information out of this book. A lot of research went into this and unfortunately there is little solid information on the topic, otherwise. Conjecture on the other hand is easy to find.The problem is, this book is horribly outdated and presumably early 1900's English is hard to follow (the first book was published in 1962). I think most people would give the book 2 stars.When the data was being taken, there were no catalytic converters, no multi-valve cylinder heads, no variable valve timing, no oxygen sensors, etc. Each of these things has an effect on how a modern exhaust system should be designed.There also seems to be some contradictions. The reflections of the wave in the exhaust are caused by every perturbation, especially openings, like where two pipes join or a pipe expands into a muffler. The strongest effect comes from the very first opening, which is where the primary pipes join. This means that primary length is the single most important part of the exhaust system tuning. Yet they provide an equation that has nothing to do with the speed of the engine or how many cylinders are employed and later, they flat out state, that the primaries should be made 18" on a four cylinder engine and then the same for a six cylinder engine, without even using their calculation.Bottom line: If you try to design your own exhaust system using only this book, you will have a very hard time of it and will likely achieve very little improvement in performance over just running it any way that fits. On the other hand, if you try to design your own exhaust system without reading this book, you will have no chance at all of improving exhaust performance. It's your choice, but beware, it is a very hard read.

Great condition book, information is outdated, but fundamentals still apply

What else can I say. Still a great reference to understand exhaust and intake dynamics and start the design of your systems.
