Abstract
Particulate solid fuel, e.g. powdered coal, is delivered into a first duct of the housing inserted into the cylinder, and thereafter moved into a second duct via a control slider. A plunger in the second duct is controlled hydraulically to move the delivered fuel through the discharge openings of a rotating ejector body when the body is in an open position in the combustion chamber.
Claims17
In an internal combustion engine having at least one cylinder defining a combustion chamber and having a reciprocating piston slidably mounted therein, the combination comprising
- means for feeding a powdered solid fuel to said cylinder, said means including a pressurized storage chamber for the fuel and a first duct connected to said storage chamber;
- a control slider disposed at an end of said first duct spaced from said storage chamber for opening and closing said first duct;
- a second duct disposed in selective communication with said first duct to receive fuel therefrom and extending to said combustion chamber;
- a rotatable ejection means disposed in said combustion chamber at an end of said second duct;
- and
- a plunger in said second duct at an end opposite said ejection means for pushing the fuel cyclically to said ejection means for ejection into said combustion chamber.

An internal combustion engine comprising
- a cylinder head;
- at least one cylinder in said head defining a combustion chamber;
- a piston slidably mounted in said cylinder;
- a housing mounted on said cylinder head coaxially of said cylinder;
- a first duct in said housing for receiving a supply of powdered fuel;
- a second duct in said housing communicating with said first duct and extending to said combustion chamber;
- a control slider in said housing disposed transversely of said second duct to separate a section of said second duct spaced from said combustion chamber from the remainder of said second duct, said slider being movable between a filling position communicating said first duct with said section while blocking said section from the remainder of said second duct and a working position communicating said section with said remainder of said second duct while blocking said first duct from said section;
- a plunger in said section of said second duct for pushing fuel cyclically towards said combustion chamber;
- a rotatable ejection means disposed in said combustion chamber at an end of said second duct;
- means for moving said ejection means axially of said second duct from a first position closing said second duct to a second position opening said second duct to said combustion chamber;
- and
- means for rotating said ejection means in said second position thereof.
