Definitions
- This invention relates to the field of engine construction, and more specifically to the ignition system of internal combustion engines (ICEs).
- ICEs internal combustion engines
- the device for ignition of fuel mixture in internal combustion engines including an ignition plug having a metal body and a ceramic insulator, inside which is a central electrode, is provided with a piezo-ceramic acoustic duct with three electrodes, one of which is connected to a power supply, the second to the body of the ignition plug or to an engine, and the third to the central electrode of the ignition plug.
- the piezo-ceramic acoustic duct may be in the form of a piezo-electric voltage transformer or a piezo-electric current transformer, or a parallel-wired piezo-electric voltage transformer and piezo-electric current transformer.
- the magnitude of the capacitance of the central electrode of the ignition plug relative to that of its body should decrease uniformly, and the magnitude of the active resistance should increase uniformly towards the discharge gap.
- the device is made and works as follows.
- the piezo-ceramic acoustic duct (5) (Fig. 1) is connected by one electrode (6) to a power supply (not shown), by a second electrode (7) to the body (2) of the ignition plug or to an engine, and by a third electrode (4) to the central electrode (3) of the plug, located inside the ceramic insulator (1) of the ignition plug.
- Fig. 2 shows the graphs of the instantaneous output power for a conventional device (curve 1) and for the use of a piezo-ceramic acoustic duct in accordance with the present invention (curve 2), the steepness of the profile of the ignition pulse, and consequently the instantaneous power, increases with the use of a piezo-ceramic acoustic duct.
- the piezo-ceramic acoustic duct (5) may be made in the form of a piezo-electric voltage transformer (Fig. 3) on the basis of a piezo-ceramic plate (8), on which the first (9), second (10) and third (11) electrodes are mounted.
- a piezo-electric voltage transformer Fig. 3
- the first (9), second (10) and third (11) electrodes are mounted.
- enhanced voltage relative to the second electrode (10) forms on the third electrode (11) of the piezo-electric voltage transformer, and the steepness of the profile of the ignition signal increases.
- the piezo-ceramic acoustic duct (5) may also be made in the form of a piezo-electric current transformer on the basis of a piezo-ceramic plate (12) (Fig. 4), on which the first (13), second (14) and third (15) electrodes are mounted.
- a piezo-ceramic plate (12) Fig. 4
- the first (13), second (14) and third (15) electrodes are mounted.
- an enhanced current relative to the second electrode (14) is formed on the third electrode (15) of the piezo-electric current transformer, and the steepness of the profile of the ignition signal again increases.
- the magnitude of the capacitance of the central electrode (3) of the ignition plug relative to its body (2) can decrease uniformly towards the discharge gap, and the magnitude of the active resistance can increase uniformly.
- a sector of non-homogeneous co-axial line forms between the central electrode (3) and the body (2).
- an increase in the steepness of the profile of the pulse transmitted through the central electrode (3) of the ignition plug takes place, as a result of which there is an increase in the instantaneous energy given off in the combustion chamber (in the discharge gap).
- the physical implementation of the change in the capacitance and active resistance of the central electrode (3) relative to the body (2) can be obtained, for example, by gradually altering the dielectric permeability and resistance of the losses of the ceramic insulator (1) of the ignition plug along the central line of the ignition plug, or by altering the shape of the ceramic insulator.
- the ignition plug contained a piezo-electric voltage transformer of standard piezo-ceramic PZT-11, dimensions 11.5 ⁇ 5 ⁇ 2 mm. In this case, the instantaneous power in the internal combustion engine increases by 18%.
- the ignition plug contained a piezo-electric current transformer of standard piezo-ceramic PZT-11, dimensions 11 ⁇ 5 ⁇ 4 mm. In this case, the instantaneous power in the internal combustion engine increases by 19%.
