While there are a great many books dealing with the theory and design of
gas engines, as well as their operation, there has been a great lack of
information relating to the care and repair of gas engines. Those that
have devoted themselves to the work of gas engine repair have Iargely
obtained their knowledge of the subject by practical experience. The
author of this treatise on gas engine repairs has been forced to obtain
his knowledge in this way, which, after aIl, Is the best, although it is
often a slow, expensive and difficult one. In order to make it easier
for others who are engaged in this work or who Intorid to enter into
this field, the most important points relative to the care and repair of
gas engines have been put down in the folIowing chapters, thereby
providing a means by which others may find it easier to become familiar
with this subject. There has always been an air of mystery surrounding
the gas engine. Often everything seems to be in the best condition and
yet the engine may refuse to start or may not develop its rated power.
The fact is, however, that, as a rule, the troubles likely to arise are
easily detected, providing one has the knowledge to look for the causes
of dificulties at such points where they may arise. Under the four heads
of Compression, Carburetion, Ignitiori and Lubrication, practically all
of the ordinary difficulties that arise in gas engine operation are
dealt with special chapters on cooling systems and on installation have
been added, the latter giving information to ouriers and others to whom
the installation of a gas engine plant may be entrusted.
