Claims
- 1. A piston engine comprising: a cylinder having an internal wall, a cylinder head, a piston reciprocatingly received in said cylinder and defining a compression space in said cylinder, an outlet channel and an outlet valve, an inlet channel in said cylinder head communicating with the cylinder through an inlet port, and end portion of said inlet channel and said inlet port being substantially coaxial with said cylinder, an inlet valve disposed substantially coaxially with the longitudinal axis of said cylinder being received in said cylinder head and closing said inlet port, a nozzle carrier carried by said inlet valve having an end projecting beyond said inlet valve and into the compression space and being temporarily received in a recess in the piston crown on part of its length, at least one nozzle means and one ignition device being provided on said nozzle carrier to form an ignitable mixture in the region of the longitudinal axis of said cylinder, and two spoons provided on the piston crown, said spoons being located opposite respective nozzles for forming the ignitable mixture at predetermined times.
- 2. A piston engine comprising: a cylinder having an internal wall, a cylinder head, a piston reciprocatingly received in said cylinder and defining a compression space in said cylinder, an outlet channel and an outlet valve, an inlet channel in said cylinder head communicating with the cylinder through an inlet port, an end portion of said inlet channel and said inlet port being substantially coaxial with said cylinder, an inlet valve disposed substantially coaxially with the longitudinal axis of said cylinder being received in said cylinder head and closing said inlet port, a nozzle carrier carried by said inlet valve having an end projecting beyond said inlet valve and into the compression space and being temporarily received in a recess in the piston crown on part of its length, at least one nozzle means and one ignition device being provided on said nozzle carrier to form an ignitable mixture in the region of the longitudinal axis of said cylinder, and two enlargements disposed opposite each other at the edge of the piston recess.
- 3. A piston engine comprising: a cylinder having an internal wall, a cylinder head, a piston reciprocatingly received in said cylinder and defining a compression space in said cylinder, an outlet channel and an outlet valve, an inlet channel in said cylinder head communicating with the cylinder through an inlet port, an end portion of said inlet channel and said inlet port being substantially coaxial with said cylinder, an inlet valve disposed substantially coaxially with the longitudinal axis of said cylinder being received in said cylinder head and closing said inlet port, means for imparting a helical movement to air unmixed with fuel about the longitudinal axis of the cylinder during the intake of the air into the cylinder, the helically flowing air being drawn into the cylinder substantially turbulence-free to form a cylinder of helically flowing air in the piston-swept and compression space, a nozzle carrier carried by said inlet valve having an end projecting beyond said inlet valve and into the compression space of the cylinder, at least one nozzle means and ignition device being provided on said nozzle carrier, and a recess provided in the piston crown which enables the piston temporarily to envelope said nozzle carrier on part of its total length.
- 4. A piston engine as claimed in claim 3, characterized in that one nozzle for forming the ignitable mixture is provided on the end face of the nozzle carrier.
- 5. A piston engine as claimed in claim 1, characterized in that the spoon has a recess or trough oriented toward the discharge opening of the nozzle.
- 6. A piston engine as claimed in claim 3, characterized in that the recess provided in the piston crown is substantially cylindrical in shape.
- 7. A piston engine as claimed in claim 3, characterized in that the recess provided in the piston crown is substantially spherical in shape.
- 8. A piston engine as claimed in claim 3, characterized in that pairs of electrodes are provided on the circumference of the nozzle carrier.
- 9. A piston engine as claimed in claim 3, characterized in that pairs of electrodes are provided on the end face of the nozzle carrier.
- 10. A piston engine as claimed in claim 1, characterized in that a channel is provided which extends from at least one spoon into the recess in the piston.
- 11. A piston engine as claimed in claim 7, characterized in that the nozzle carrier substantially closes the spherical recess provided in the piston crown at a predetermined position of the piston.
- 12. The piston engine as claimed in claim 3 characterized in that said means for imparting rotating movement to the air is provided in said inlet port.
- 13. The piston engine as claimed in claim 3 characterized in that two nozzle means are provided on the circumference of said nozzle carrier, said nozzles being disposed at an angle of 180.degree. to each other.
- 14. A piston engine as claimed in claim 3 including a spoon on the piston in the region of the recess.
- 15. A piston engine as claimed in claim 3 including at least one electrode on the circumference of the nozzle carrier.
- 16. A piston engine as claimed in claim 3 including at least one electrode on the end face of the nozzle carrier.
