Internal combustion engine
First Claim
1. An internal combustion engine comprising:
- a plurality of cylinders including combustion chambers, wherein an ignition device or a fuel introduction device is associated with each of the combustion chambers, wherein the combustion chambers are adapted for cyclic ignition of fuel,an open-loop or closed-loop control device for actuation or closed-loop control of the ignition devices or the fuel introduction devices, anda plurality of measuring devices, each for detecting a temperature which is characteristic for one of the cylinders,wherein the open-loop or closed-loop control device is adapted for actuation or closed-loop control of the ignition devices or the fuel introduction devices in dependence on signals of the measuring devices such that (i) the ignition device or the fuel introduction device associated with at least one of the cylinders is inactive during at least one cycle in a situation in which the characteristic temperature of at least one of the cylinders reaches or exceeds a predeterminable upper value for actuation or closed-loop control of the at least one of the cylinders, and (ii) the ignition device or the fuel introduction device associated with at least one of the cylinders is active in a situation in which the characteristic temperature of the at least one of the cylinders reaches or falls below a predeterminable lower value for actuation or closed-loop control of the at least one of the cylinders,whereby an even temperature distribution over all of the cylinders is achieved, andwherein the predeterminable upper value or the predeterminable lower value is established based on an average temperature of all of the cylinders.

Abstract
An internal combustion engine comprising: a plurality of cylinders in which combustion chambers are provided, wherein an ignition device and/or a fuel introduction device is associated with each combustion chamber, wherein the combustion chambers are adapted for cyclic ignition of fuel, an open-loop or closed-loop control device for actuation or closed-loop control of the ignition devices and/or fuel introduction devices, and at least one measuring device for detecting a temperature which is characteristic for each cylinder, wherein the open-loop or closed-loop control device is adapted for actuation or closed-loop control of the ignition devices or the fuel introduction devices in dependence on the signals of the at least one measuring device so that no ignition takes place in at least one selected cylinder during at least one cycle and that an even temperature distribution over all cylinders is achieved.

9. A method of operating an internal combustion engine having a plurality of cylinders including combustion chambers, wherein an ignition device or a fuel introduction device is associated with each of the combustion chambers, wherein the combustion chambers are adapted for cyclic ignition of fuel, the internal combustion engine having an open-loop or closed-loop control device for actuation or closed-loop control of the ignition devices or the fuel introduction devices, and a plurality of measuring devices, each for detecting a temperature which is characteristic for one of the cylinders, wherein the open-loop or closed-loop control device is adapted for actuation or closed-loop control of the ignition devices or the fuel introduction devices in dependence on signals of the measuring devices such that (i) the ignition device or the fuel introduction device associated with at least one of the cylinders is inactive during at least one cycle in a situation in which the characteristic temperature of the at least one of the cylinders reaches or exceeds a predeterminable upper value for actuation or closed-loop control of the at least one of the cylinders, and (ii) the ignition device or the fuel introduction device associated with at least one of the cylinders is active in a situation in which the characteristic temperature of the at least one of the cylinders reaches or falls below a predeterminable lower value for actuation or closed-loop control of the at least one of the cylinders, whereby an even temperature distribution over all of the cylinders is achieved, and wherein the predeterminable upper value or the predeterminable lower value is established based on an average temperature of all of the cylinders.
