PREFACE
My object in placing this handbook before the reader is to provide him with a simple and straightforward explanation of how and why a gas engine, or an oil engine, works. The main features and peculiarities in the construction of these engines are described, while the methods and precautions necessary to arrive at desirable results are detailed as fully as the limited space permits. I have aimed at supplying just that information which my experience shows is most needed by the user and by the amateur builder of small power engines. In place of giving a mere list of common engine troubles and their remedies, I have thought it better to endeavour to explain thoroughly the fundamental principles and essentials of good running, so that should any difficulty arise, the engine attendant will be able to reason out for himself the cause of the trouble, and will thus know the proper remedy to apply. This will give him a command over his engine which should render him equal to any emergency.

CHAPTER I
INTRODUCTORY
The history of the gas engine goes back a long way, and the history of the internal combustion engine proper further still. It will be interesting to recount the main points in the history of the development of the class of engine we shall deal with in the following pages, in order to show what huge strides were made soon after the correct and most workable theory had been formulated.
Table of contents (by pages)
- 1: Gas and Oil Engines, Simply Explained by Runciman
- 2: And drove a piston in a double working cylinder
- 3: Invented by Otto Langen about this time
- 4: With compression before ignition
- 5: Showing the cylinder and liner
- 6: Are usually of brass or gun metal
- 7: The expanding gases driving the piston rapidly before them
- 8: Further reference to A the mixer
- 9: And the high tension magneto ignition
- 10: The adjustment of the ignition tube
- 11: Asbestos linings gradually become worn and ragged
- 12: And is frequently surrounded by an asbestos lining
- 13: Which is merely a small bunsen burner
- 14: Precisely the same action takes place in our magneto igniter
- 15: And so back to other terminal on magneto
- 16: It is screwed into a pecker block B
- 17: Which carries the pecker P pivoted at the upper end of L
- 18: With all three valves mechanically operated
- 19: Through point E draw a line forming a tangent to circle GHJ
- 20: And the keyway cut in the side shaft
- 21: This gas or governor cam may be set out
- 22: With small high speed engines fitted with suction air valve
- 23: 14 x D x R 33000 S1 Reading in lbs
- 24: And overflow into the vapourising chamber
