This invention relates to internal combustion thus possible to maintain a uniform ratio of fuel engines of the kind in which a combustible charge to air for all values of the engine output. of petrol or other volatile fuel is ignited in a Referring to Fig. 2, the sprayer or injector comcombustion chamber or engine cylinder by means prises a body It adapted to be inserted through 5 of a sparking or like device. an aperture in the wall of an engine cylinder or 5 The invention has for its object to provide an cylinder head and may be screw-threaded for internal combustion engine of the above type this purpose preferably with the same thread as which is also adapted to operate on heavy or nonthat which is employed for standard sparking volatile oil, such for example as is used for Diesel plugs.

It is on account of the low cost of this oil as compared 55 with petrol, power may thus be very economically obtained. Such engines, however, as compared with petrol engineshave the disadvantages of increased weight, and roughness of running, because of their high compression ratio and are limited in speed. An engine adapted according to the present invention to use heavy oil retains the characteristics of the low compression petrol engine, these being, lightness, smoothness of running and high speed and has, at the same time, the
advantage of using a cheap fuel. a
It is to be understood that the invention is not limited to the above details except in the manner set forth. I
I claim:
1. A fuel injection nozzle for an internal combustion engine comprising a body portion, an internal surface defining an orifice; in said body portion, a concavely curved deflecting surface surrounding said orifice, a sleeve portion surrounding said deflecting surface, and an additional deflector located so as to lie across the path of fluid issuing from the orifice and having an annular deflecting surface concavely curved to said ad.-
ditional deflector, the deflecting surfaces on said body portion and said additional deflector facing each other in such a manner that fluid issuing from the nozzle is deflected by said deflector back onto the body and thence through the space between the deflector and sleeve.
2. A fuel injection nozzle for an internal combustion engine comprising a body portion, an internal surface defining an orifice in said body portion, a concavely curved deflecting surface surrounding said orifice, a sleeve portion surrounding saiddeflecting surface, a needle valve adjusting the size of said orifice, an extension to said needle valve extending beyond said sleeve, and a deflecting disc carried on the end of said needle valve extension in spaced relationship with the edge of said sleeve and having an annular concavely curved deflecting surface thereon, the defleeting surfaces on said body and said disc facing each other so that fluid issuing from the orifice is deflected by the disc back onto the surface surrounding the orifice and :thence through :the space between the sleeve and the disc.
