Problems solved by technology

[0006] A disadvantage of the international application WO 2010 / 011838 A1 is that sporadic spark discharges cannot be avoided when the gas mixture is ignited by corona discharge, since the detection of the occurrence of spark discharges is a prerequisite for establishing the impedance setpoint
However, only occasional or sporadic spark discharges may lead to insufficient combustion during spark defects and wear out the ignition electrodes.

Embodiment Construction

[0063] refer to figure 1 , the combustion chamber 1 is surrounded by grounding cavity walls 2, 3, 4, the ignition electrode 5 shoots into the combustion chamber 1 from above, and part of the ignition electrode 5 is covered by an insulating medium 6, so that the ignition electrode 5 is insulated from the The upper chamber wall 2 extends into the combustion chamber 1 . A set of oscillating circuits 7 includes the ignition electrode 5 and the walls 2 to 4 of the combustion chamber 1 , and also includes a capacitor 8 and an inductor 9 . Those skilled in the art who are familiar with oscillating circuits can also add more capacitors and / or inductors and other components to the oscillating circuit 7 .

[0064] A radio frequency generator 10 is used to excite the oscillating circuit 7, said generator comprising a DC source 11 and a transformer 12 with a center tap 13 on the first side of the transformer 12 to which two first windings 14 and 15 are connected . Via the radio frequen...

Abstract

The method involves connecting an electric voltage to a primary winding before each ignition point of a combustion engine. The primary winding is subsequently identified as primary voltage and is increased stepwise. The strength of the electric current flowing in the primary winding as consequence of primary voltage is subsequently identified as primary current and is repeatedly measured at the same voltage.

Description

technical field [0001] The invention relates to an ignition method of an internal combustion engine, in particular to an ignition method of mixed gas in a combustion chamber of an internal combustion engine based on corona discharge. Background technique [0002] The technical features of the foregoing part of claim 1 of the present invention have been disclosed in the patent literature of the international application WO 2010 / 011838 A1. International application WO 2004 / 063560 A1 discloses a method for igniting mixed gas in the combustion chamber of an internal combustion engine with corona discharge in the combustion chamber. Opposed to the reciprocating piston in the combustion chamber. The ignition electrode, together with the grounded chamber wall of the combustion chamber as counter electrode, forms a capacitor. The combustion chamber and its contents are not charged together. The combustion chamber contains air, mixed gas or burnt exhaust gases depending on the cyc...
