Abstract:
A PCM ( 100 ) selects one of a CI mode or an SI mode based on the operating conditions of the engine ( 1 ). In the CI mode, the engine ( 1 ) is operated by compression ignition combustion. In the SI mode, the engine ( 1 ) is operated by spark ignition combustion. if, while the engine ( 1 ) is being operated in the CI mode, a determination is made that an estimated value (Tc) of the catalyst temperature is lower than or equal to a warming start temperature (Ts), the PCM ( 100 ) further performs first warming control to assign four cylinders ( 18 ) as CI and SI cylinders, which perform the compression ignition combustion and the spark ignition combustion, respectively, such that the four cylinders ( 18 ) alternately perform the compression ignition combustion and the spark ignition combustion in accordance with the order of combustion of the cylinders.

Claim (Index 6):
The engine control device of  claim 1 , further comprising:\n exhaust valves each capable of opening and closing an associated one of outlets through each of which gas is discharged from inside of an associated one of the cylinders to the exhaust passage; and exhaust valve drive mechanisms configured to individually control opening and closing of the exhaust valves on a cylinder-by-cylinder basis, wherein the exhaust valve drive mechanisms are configured to be able to open and close the exhaust valves such that subsequent to a main valve opening operation performed during an exhaust stroke, a subsequent valve opening operation is performed to allow the exhaust valves to be open during an intake stroke, and under the warming control, the controller controls the exhaust valves via the exhaust valve drive mechanisms to allow the main valve opening operation and the subsequent valve opening operation to be performed for the exhaust valve of the CI cylinder.
