Abstract
Powdered fuel charges are injected mechanically into a pocket in the piston during a first half of a compression stroke for subsequent expulsion into the combustion chamber during the second half of the compression stroke. The dosing and ejecting means is mounted in the cylinder wall and includes a plunger which ejects the fuel charges from a duct. Movement of the plunger in the duct is cyclically blocked by a slider during filling of the duct with a fuel charge.
Claims14
In a reciprocating internal combustion engine the combination comprising
- at least one cylinder having a wall defining a combustion chamber;
- a piston slidably mounted in said cylinder to move into said combustion chamber during a compression stroke, said piston having a centrally disposed pocket in a surface thereof facing said combustion chamber, said pocket having an undercut portion in a peripheral surface thereof;
- and
- a mechanical fuel dosing and ejecting means mounted on said cylinder wall for ejecting powdered fuel cyclically and tangentially into said pocket for initial collection under said undercut during a first half of said compression stroke and for release into said combustion chamber during a second half of said compression stroke under the influence of decreasing centrifugal force and increasing axial deceleration of said piston.
