An improved engine is provided that more efficiently consumes difficult fuels such as coal slurries or powdered coal. The engine includes a precombustion chamber having a portion thereof formed by an ignition plug. The precombustion chamber is arranged so that when the piston is proximate the head, the precombustion chamber is sealed from the main cylinder or the main combustion chamber and when the piston is remote from the head, the precombustion chamber and main combustion chamber are in communication. The time for burning of fuel in the precombustion chamber can be regulated by the distance required to move the piston from the top dead center position to the position wherein the precombustion chamber and main combustion chamber are in communication.

Internal combustion engine

A fuel injection nozzle including a valve having an axial hole therethrough for feeding a first fuel to a collection zone and having a pathway for alternately feeding a second fuel to the same or different collection zone to enable the single nozzle to inject separate streams of each fuel into a compression ignition engine combustion chamber.

Fuel injection nozzle

Apparatus for producing a reciprocating oscillation of a power output shaft comprises a plurality of peripherally spaced cylinders disposed in generally tangential relationship to the periphery of a cylindrical fluid pressure chamber and connected at their inner ends to such fluid pressure chamber. The gas pressure in such chamber is regulated to maintain a selected value above ambient. Cooperating pistons in each of the cylinders are interconnected by connecting rods to a spoke-like rocker element which is freely oscillatable about the output shaft to which the housing defining the cylindrical fluid pressure chamber is secured for co-rotation. A flywheel mass is connected to the spokes of the rocker element. Inlet and exhaust valves are provided in a cylinder head mounted in the outer end of each cylinder and are operable by contact with the outer face of the respective piston. A radial exhaust port is uncovered by each piston as it nears the end of its power stroke, thus reducing the fluid pressure on the outer piston face to ambient and permitting the regulated fluid pressure chamber to effect the return of the pistons to their outermost pistons relative to the cylinder.

Multi-cylinder piston engine and method of operation thereof

There is disclosed an actuator which enables the intake valves which control the induction of a combustible fuel-air mixture into the combustion chambers of a spark-ignited or dual-fuel internal combustion engine to be opened for time intervals proportional to load or demand on the engine.
