Description: |
| Claim:
To This invention relates to explosive-engines in which the hydrocarbon, which forms the basis of the explosive mixture, is delivered in a liquid form and is introduced into the working cylinder of the explosion-chamber after each explosion in a quantity sufficient to form the next charge, the hydrocarbon being vaporized within the working cylinder. The hydrocarbon or oil is commonly delivered by a force-pump, the stroke of which is varied to increase or diminish the quantity of oil supplied. It has also been proposed to deliver the oil by gravity. The desirability of providing for a uniform delivery of the oil at least to the point where the engine-governor regulates the delivery in order that the speed of the engine shall not be subject to variations has been generally recognized. Experience has shown, however, that the various methods hitherto employed of feeding the oil by gravity have failed to provide for an absolutely unvarying and uniform head. In all of such eases, so far as I am aware, the oil has been delivered from closed tanks under pressure or from closed tanks from which the oil escapes from time to time as the delivery- openings of the tanks are uncovered by the withdrawal of oil from another vessel, and air is admitted to the closed vessels to displace the oil therein. Without complicated, delicate, and expensive devices it is impossible to maintain absolutely uniform pressure upon the oil in the closed vessels, and in the other class of devices referred to it is obvious that the level of the oil outside of the closed vessels must change sufficiently to at least cover and uncover the delivery-orifice of the closed vessel. In view of the very small quantity of oil used at each explosion it is evident that even the slight variations of pressure or head thus occasioned will produce a relatively great change in the quantity of oil actually delivered and will effect the operation of the engine to a corresponding degree. |
