PREFACE.
Though much has already been written on the subject of traction by means
of locomotives and motor coaches driven by combustion engines, this has to be
sought in a wide range of various periodicals, which fact induced the late Professor
Franco to embody these scattered publications in a book for ready reference by rail
way engineers and managements. He considered it advisable to treat first and fore
most of the use of combustion engines in rail-motor coaches, small locomotives and
similar traction vehicles.
Professor Franco invited me to assist in the compilation of this work, and this
invitation I gladly accepted.
It was decided that no special scientific treatise on combustion engines and
accessories was required, but rather a book that could be consulted by anyone
interested in the problem of the application of combustion engines on railways in
order to see whit had already been attained in this direction in the various countries
of the world. Furthermore it was considered that an extensive bibliography would
enable the reader to trace any further information he might desire.
Unfortunately Professor Franco, who was my tutor and afterwards my chief
on the Netherlands Railways, died just as the manuscript reached completion, but
nevertheless I believe to be acting in accordance with his wishes and those of his
family in having this book published as the fruit of our joint labour.

INTRODUCTION.
Transport is one of the most important problems of the present day. Notwith
standing the increase of motor transport during recent years and the continuous
advance in air transport, railway transport will always occupy a very prominent
place.
Since the beginning of railways more than a century ago the only traction vehicle
until comparatively recent date was the steam engine, and this, through years of
experience, has reached a high standard of perfection.
Nevertheless the efficiency of the most perfect steam locomotive is still very small.
Various attempts have been made to increase its efficiency by applying turbines
or steam under very high pressure, but so far very little has been achieved in this
direction beyond the experimental stage, so that more general application cannot
yet be expected. Thus it is not at all surprising that another way should have been
sought to build a more economical locomotive. This led to the use of internal-com
bustion engines instead of steam engines, a rather obvious solution considering the
great success already attained with this type of engine on board ships. Although
the requirements of marine engines are different and in some ways less exacting,
the still greater perfection reached in the design of internal-combustion engines and
the improvements which are constantly being made as more experience is gained,
justify the expectation that this engine will also give every satisfaction in railway
work. It may even be said now already that in special cases the internal-combustion
engine is the one most eminently suitable for locomotives, as indeed appears from
the fact that railway companies all the world over have taken to this type.
A great advantage of internal-combustion engines is that they can be applied not
only to locomotives but also to motor vehicles, a possibility which is practically pre
cluded with steam engines; at any rate they have not been generally used in this
way. A comparison of the advantages and disadvantages of the steam engine with
those of the internal-combustion engine as applied to traction vehicles shows that:
The advantages of the internal-combustion engine compared with the steam
engine are:
1) Much higher efficiency.
This efficiency, that is to say the proportion of the fuel energy converted
into work performed at the periphery of the driving-wheels, is no more than 8%
for the most perfect steam locomotive, whereas with the internal-combustion
engine locomotive an efficiency of 25% is reached.
2) Readiness for immediate service.
In a steam locomotive the steam has first to be generated, which, unless
the engine is kept under steam, occupies a few hours and means extra cost of
fuel and wages.
3) No fuel costs while the locomotive is at a standstill.
With steam engines the fire has to be stoked whether the locomotive is in
motion or not.
4) In some cases there is no cost of wages while the locomotive is idle.
8
For shunting engines, which, especially at smaller stations, are idle for
several hours a day, a saving is effected through the engine-driver being able to
do other work or take his off-hours during that time.
5) No consumption of water.
This is especially an advantage in countries where water is scarce, or where
boiler-feed water is expensive.
6) The possibility for longer journeys.
Mter a journey of 200 to 300 km the fire of a steam engine has to be cleaned.
An internal-combustion engine can be kept running for any length of time.
7) Generally a lower wage-bill.
A steam train requires at least an engine-driver, a fireman and a guard.
A motor train needs only one man. For a motor shunting engine one man
suffices, whereas a steam shunting engine needs an engine-driver and a fireman.
8) Cheaper handling of the fuel at depots.
The liquid fuel only requires pumping out of the tank cars into the storage
tanks and out of these into the tank of the traction vehicle.
The disadvantages are:
1) Higher initial cost.
A motor locomotive to-day costs about twice as much as a steam locomotive.
For motor vehicles the cost has to be compared with that of a small steam loco
motive plus trailer, and in this case the difference in price will be of little im
portance.
2) Smaller overload-capacity.
An internal-combustion engine can only be slightly overloaded and only
during a short time, as otherwise troubles may occur through fouling of the
engine. A steam engine, on the other hand, can be considerably overloaded,
though at the cost of efficiency. ·
3) More complicated construction.
4) Heavier weight for locomotives.
The data given hereafter for locomotives already built will give some idea
of this factor.
Another factor is, of course, the cost of fuel, but at the time of writing this
book fuel prices have changed to such a considerable extent that it is deemed
inadvisable to make any comparisons. When considering the cost due thought is also
to be given to local conditions.

I. THE ENGINE.
Types.
Diesel and petrol engines are generally called internal-combustion engines.
Combustion engines are engines consisting of one or more cylinders in each of which
a piston moves reciprocatingly. This movement of the piston is converted by means
of a connecting-rod and a crank into a rotatory motiori. The piston is propelled by
the ignition of the fuel fed into the cylinder, the combustion gas enclosed between
cylinder cover and piston exercising a strong pressure upon the piston and thus
setting it in motion, while the gas gradually expands. In this respect there is much
similarity between the combustion engine and an ordinary steam engine, the typical
difference being that the combustion gas inside the cylinder of the combustion engine
has a much higher temperature than the steam in a steam engine. This makes it
necessary to provide the cylinders of combustion engines with cooling jackets.
Pardy in consequence of this intense heat double-acting engines are apt to give
trouble at the stuffing-box and with the cooling of the piston, and for this reason
combustion engines are nearly always made single-acting, except in the case of the
very largest types, which, however, up to the present are not to be considered for
traction purposes.
There are two principal types of combustion engines: the Diesel engine and
the explosion engine. Formerly the Diesel engine was also called a constant pressure
engine, as the combustion was rather gradual, the explosion engine als<Y a constant
volume engine, as the combustion was rather instantaneous. To-day this contrast
has disappeared as both types of engines have a more mixed type of combustion 1).
Figures 1 and 2 show the theoretical diagrams of a constant volume engine
and a constant pressure engine, whilst figure 3 shows a theoretical diagram of a
more mixed type of combustion. Figures 4 to 9 are illustrations ·of various construc
tions, from which it will be seen that these engines when used for locomotives are
invariably of the vertical type.
The combustion cycle.
To attain a high efficiency it is necessary that the fuel charge burns completely.
Complete combustion can only be effected with a surplus of air, because only one
fifth part of the air consists of oxygen, making it less effective. This surplus of air
is particularly needed also because the combustion has to be completed quickly
and consequently every particle of the fuel must receive immediately the necessary
quantity of oxygen. For the combustion of one kg of fuel about 15 m3 air is required
in a petrol engine and about 20 m3 in a Diesel engine.
1) The characterising feature of a Diesel engine, according to the inventor, is: Compression
of the combustion air without fuel until considerably above the ignition point of the fuel; then
the adding of the fuel and the immediate combustion of same in this highly compressed hot air.
If, in an internal-combustion engine, air without fuel is compressed but instead of the ignition
taking place through the hot compressed air the fuel is ignited by other means (for instance by a
hot surface) then this engine cannot really be called a Diesel engine.
