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 above all low price. /This ideal he has, however, failed to reach, although his engine has many good points. He fails chiefly because the mechanism is too complicated. The motor works with an Otto cycle, and the ignition is by an electric spark generated by a small magneto machine. The regulation of the speed is obtained by throttling the admission, and the air is drawn through a tube heated by the waste gases; this arrange ment allows a slight economy to be effected. The carburator is automatic, consisting of a closed cylinder placed vertically over the motor cylinder. Within it is placed the oil fuel, and also a spongy mass of cork which soaks up the heavier impurities found in the oil, and therehy allows cheaper oils to...
