INTERNAL COMBUSTION ENGINE
First Claim
1. Internal combustion engine comprising:
- a controller;
at least one combustion chamber;
at least one sensor operable to produce signals supplied to the controller; and
at least one ignition amplifier associated with the combustion chamber;
wherein the at least one combustion chamber via a feeding device for a fuel-air mixture is supplied with energy, or is supplied with energy by the at least one ignition amplifier;
wherein the controller changes an excess-air ratio of the fuel-air mixture in a detection mode for the at least one combustion chamber;
wherein the at least one sensor produces signals characteristic of a combustion event in the at least one combustion chamber; and
wherein the controller, depending on the signals supplied by at least one sensor, generates a representative detection signal associated with a status of the at least one ignition amplifier associated with the at least one combustion chamber.

Abstract
Internal combustion engine (1) with a controller (2) and at least one combustion chamber (3) and an at least one ignition amplifier (4) associated with the combustion chamber (3), whereby the at least one combustion chamber (3), on the one hand via a feeding device (5) for a fuel-air mixture, can be supplied with energy, and on the other hand can be supplied with energy by the associated ignition amplifier (4), whereby the controller (2) is designed to change the excess-air ratio (λ) of the fuel-air mixture in a detection mode for the at least one combustion chamber (3), and at least one sensor (6) is provided, whose signals can be supplied to the controller (2) and whose signals are characteristic of the combustion event in at least one combustion chamber (3) and that the controller (2) is designed such that, depending on the signals supplied by at least one sensor (6), a representative detection signal is generated associated with a status of the at least one ignition amplifier (4) associated with at least one combustion chamber (3).

15. A method for checking a status of an ignition amplifier associated with at least one combustion chamber of an internal combustion engine, comprising:
- for the at least one combustion chamber, changing the excess-air ratio of a fuel-air mixture; and
inferring as a function of a characteristic signal for a combustion event in the at least one combustion chamber, the status of the ignition amplifier associated with the at least one combustion chamber.
- for the at least one combustion chamber, changing the excess-air ratio of a fuel-air mixture; and
