A method of operating a combustion engine, in which post-injections of fuel by means of an injector valve occur in at least one cylinder (16, 18, 20, 22) of the combustion engine for supporting regeneration of a particle filter disposed in an exhaust tract of the combustion engine downstream of an oxidation catalytic converter, characterised in that an advance for an opening time and a closing time of an exhaust valve of a cylinder (16, 18, 20, 22) of the combustion engine is performed such that intermediate compression of exhaust gas occurs in the combustion chamber of the cylinder (16, 18, 20, 22), wherein the advance of the opening time and the closing time is performed in a first temperature range (Δθ1) for a temperature (θ) of the oxidation catalytic converter, and the post-injections occur in a second temperature range (Δθ2) for the temperature (θ) of the oxidation catalytic converter, wherein - a range upper limit (Δθ1 o) of the first temperature range (Δθ1) has a lower value than a range upper limit (Δθ2 o) of the second temperature range (Δθ2); - a range lower limit of the second temperature range (Δθ2) corresponds at least approximately to a light-off temperature (θ A) of the oxidation catalytic converter; - the range upper limit (Δθ1 o) of the first temperature range (Δθ1) falls in the second temperature range (Δθ2), wherein the range upper limit (Δθ1 o) of the first temperature range (Δθ1) exceeds the light-off temperature (θ A) by no more than about 20 K; - within the first temperature range (Δθ1), a reduction of the advance for the opening time and the closing time of the exhaust valve substantially occurs with increasing temperature (θ); - in the region of the light-off temperature (θ A) of the oxidation catalytic converter, an increasingly high reduction of the advance of the opening time and the closing time occurs with increasing temperature (θ) of the oxidation catalytic converter; and - upon reaching the range upper limit (Δθ1 o) of the first temperature range (Δθ1), the advance of the timings is fully reversed. in that an advance for an opening time and a closing time of an exhaust valve of a cylinder (16, 18, 20, 22) of the combustion engine is performed such that intermediate compression of exhaust gas occurs in the combustion chamber of the cylinder (16, 18, 20, 22), wherein the advance of the opening time and the closing time is performed in a first temperature range (Δθ1) for a temperature (θ) of the oxidation catalytic converter, and the post-injections occur in a second temperature range (Δθ2) for the temperature (θ) of the oxidation catalytic converter, wherein - a range upper limit (Δθ1 o) of the first temperature range (Δθ1) has a lower value than a range upper limit (Δθ2 o) of the second temperature range (Δθ2); - a range lower limit of the second temperature range (Δθ2) corresponds at least approximately to a light-off temperature (θ A) of the oxidation catalytic converter; - the range upper limit (Δθ1 o) of the first temperature range (Δθ1) falls in the second temperature range (Δθ2), wherein the range upper limit (Δθ1 o) of the first temperature range (Δθ1) exceeds the light-off temperature (θ A) by no more than about 20 K; - within the first temperature range (Δθ1), a reduction of the advance for the opening time and the closing time of the exhaust valve substantially occurs with increasing temperature (θ); - in the region of the light-off temperature (θ A) of the oxidation catalytic converter, an increasingly high reduction of the advance of the opening time and the closing time occurs with increasing temperature (θ) of the oxidation catalytic converter; and - upon reaching the range upper limit (Δθ1 o) of the first temperature range (Δθ1), the advance of the timings is fully reversed. - a range upper limit (Δθ1 o) of the first temperature range (Δθ1) has a lower value than a range upper limit (Δθ2 o) of the second temperature range (Δθ2); - a range lower limit of the second temperature range (Δθ2) corresponds at least approximately to a light-off temperature (θ A) of the oxidation catalytic converter; - the range upper limit (Δθ1 o) of the first temperature range (Δθ1) falls in the second temperature range (Δθ2), wherein the range upper limit (Δθ1 o) of the first temperature range (Δθ1) exceeds the light-off temperature (θ A) by no more than about 20 K; - within the first temperature range (Δθ1), a reduction of the advance for the opening time and the closing time of the exhaust valve substantially occurs with increasing temperature (θ); - in the region of the light-off temperature (θ A) of the oxidation catalytic converter, an increasingly high reduction of the advance of the opening time and the closing time occurs with increasing temperature (θ) of the oxidation catalytic converter; and - upon reaching the range upper limit (Δθ1 o) of the first temperature range (Δθ1), the advance of the timings is fully reversed.
