Embodiment Construction

[0032] figure 1 An internal combustion engine 1 , the operation of which can be used to carry out the method according to the invention, is shown in an exemplary and schematically, particularly strongly simplified, manner. The internal combustion engine 1 provided as a gas engine with combustible gas injection (running lean) with combustible gas, for example in the form of natural gas, biogas, specialty gas, landfill gas, hydrogen, has a cylinder 3 with a delimited combustion space 5 In this cylinder, that is to say between the reciprocating piston 7 and the combustion space cover 9 . Arranged on the combustion space 5 , in particular on the cylinder head or the combustion space cover 9 of the cylinder 3 , and thus projecting into the combustion space 5 , is a spark plug 11 for ignition of the combustible gas-air mixture.

[0033] Spark plug 11 is provided as a prechamber spark plug and is connected via plug plug 13 with ignition line 15 to ignition device 17 of internal comb...

Abstract

The invention relates to a method for implementation with the operation of an internal combustion engine (1), having an ignition plug (11), which is arranged on a combustion chamber (5) of a cylinder(3) of the internal combustion engine (1), wherein: in a first step, a cylinder pressure at the ignition time (pzzp) at the combustion chamber (5) is detected, as well as a breakdown voltage (UZZP) atthe ignition plug (11); and in a second step, a current electrode distance (EA) of the ignition electrodes, representing a current ignition electrode wear state, is determined based on the detected cylinder pressure (pzzp), the detected breakdown voltage (UZZP) and a constant of proportionality (K).

Description

technical field [0001] The invention relates to a method for carrying out with the operation of an internal combustion engine according to claim 1 . Background technique [0002] Spark plugs are subject to considerable fluctuations in their operating time during use with Otto motors, in particular likewise gas engines. Thus, for example, in engines with variable speed and load, low combustion air ratios are used to meet short periods of time, which accelerate the combustion, resulting in too high a combustion space due to the additional heat flow in the wearing elements of the spark plugs. temperature and lead to excessive wear on the spark plugs. This increased wear has a higher scatter with respect to safety over time, which can disadvantageously lead to unforeseen failures. Contents of the invention [0003] Starting from this, the invention is based on the task of specifying a method by which failures can be predicted. [0004] This object is achieved by a method wi...
