Abstract

An ignition system of an internal combustion engine comprising ignition electrodes positioned in a bottom part of the engine head, characterized in that the ignition electrodes (2, 3) are mounted on a periphery of a combustion chamber (4) in head cavities (5), which are arranged around a cylinder (6) of an engine block (7).

Description

    TECHNICAL FIELD
  • The present invention relates to an ignition system of a combustion engine, designed to ignite the fuel-air mixture in its cylinder.
    • BACKGROUND
  • Ignition systems of a combustion engine, as disclosed herein, have not been described in professional publications so far.
    • SUMMARY
  • In the ignition system presented herein, ignition electrodes are mounted on a periphery of a combustion chamber in head cavities that are arranged around a cylinder of an engine block.
    • BRIEF DESCRIPTION OF DRAWINGS
  • Further details and features of the present invention, its nature and various advantages will become more apparent from the following detailed description of the preferred embodiments shown in a drawing, in which:
    • Fig. 1 shows a longitudinal section of an internal combustion engine,
    • Fig. 2 shows an internal combustion engine in the section A-A of Fig. 1.
    DETAILED DESCRIPTION
  • An ignition system of an internal combustion engine has ignition elements 1 equipped with ignition electrodes 2, 3, which are mounted on a periphery of a combustion chamber 4 in cavities of a head 5. These cavities are arranged around a cylinder 6 of an engine block 7. A piston 8 is located in the cylinder.
  • The operation of the ignition device of the internal combustion engine consists in that at the end of the compression stroke of the fuel-air mixture in the cylinder 6 by the piston 8, a spark-over between the ignition electrodes 2, 3 occurs at the same time. This causes the circumferential ignition of the fuel-air mixture and the movement of the flame from the periphery of the combustion chamber 4 and the cylinder 6 towards its axis in the direction of the piston 8.
  • The advantage of the presented ignition system is a peripheral ignition of fuel-air mixture which causes orientation of the exhaust gas energy towards the centre of the cylinder, towards the piston's surface. This results in a uniform and rapid burning of the mixture within the volume of the combustion chamber, which results in a uniform impact of exhaust gases onto the surface of the piston. Another advantage is a reduction of wear of the cylinder wall by propagation of the combustion process toward the surface of the piston, as well as a reduction of the thermal load of the ignition elements by distributing the ignition to many ignition elements (by spreading the plurality of ignition plugs).
