The hydrocarbon vapour produced during the fall, and afterwards by the heat of the substratum of water, passes by a check-valve to the motor. It is found that the cleansing effect of the water renders the cylinder much less liable to become fouled by tarry products. Lothhammer carburator.--Experience has shown that vapour of petroleum when mixed with air soon separates out; the vaporizer must therefore be placed as close to the engine as possible. In this motor it has been the aim of the inventor to obtain an exceedingly perfect mixture of the explosive gases. In order to do this the air enters the vaporizer near its base, and passes through it in a number of exceedingly fine streams of bubbles. The petroleum spirit is at the same time heated by a flame, and the result is a very close mixture of the gases. The inventor claims that he thereby obtains much more complete combustion. Tenting motor.--M. Tenting has arranged his gas engine, which we have already described on page 57, for use also as an oil engine. The carburator is composed of three superposed vessels, through each of which the oil flows in turn. The upper vessel acts as a reservoir and will hold a day's consumption of oil, and the lower one is traversed by the exhaust pipe, which supplies the heat necessary to obtain the change of state of the oil from liquid to gas. Although this carburator is rather crude it gives a very fair practical result. Durand carburetted air engine (Fig. 27).--M. Durand has set himself to produce a motor which should work equally well with gas or petroleum, and which should require a minimum of attention at the same time, keeping in view such points as regularity of speed, rigidity, economy of space, and ...
