Piston engine and operating method
First Claim
1. A method for operating an engine, comprising:
- adjusting a target load, which lies below a full load;
operating at least one cylinder in a first cylinder group with a first load, which is reduced with respect to the target load;
operating at least one cylinder in a second cylinder group with a second load, which is increased with respect to the target load;
selecting the first and second loads such that a resulting load is the target load; and
selecting the first and second loads such that at least one environmental parameter value is improved, wherein the environmental parameters include at least one of a fuel consumption, a nitrogen oxide content in the exhaust gas, and a particle content in the exhaust gas.

Abstract
A method for operating an engine, including, adjusting a target load, which lies below a full load; operating at least one cylinder in a first cylinder group with a first load, which is reduced with respect to the target load; operating at least one cylinder in a second cylinder group with a second load, which is increased with respect to the target load; selecting the first and second loads such that a resulting load is the target load; and selecting the first and second loads such that at least one environmental parameter value is improved, wherein the environmental parameters include at least one of a fuel consumption, a nitrogen oxide content in the exhaust gas, and a particle content in the exhaust gas.

17. A engine, comprising:
-
a first cylinder group, which has at least one cylinder; a second cylinder group which has at least one cylinder; and a control device which is at least one of configured and programmed to approximately maintain a target load, wherein the first cylinder group includes a first load, which is reduced relative to the target load and the second cylinder group includes a second load, which is reduced relative to the target load. - View Dependent Claims (18, 19, 20, 21)
