A fuel injector (6) and spark plug (7) are arranged in a combustion chamber (5) of an internal combustion engine. By forming by stratification a self-ignitable preliminary air-fuel mixture in the combustion chamber (5), a spatial distribution is given to the density of the preliminary air-fuel mixture in the combustion chamber (5). Part of the preliminary air-fuel mixture formed in the combustion chamber (5) is ignited by the spark plug (7) to cause combustion by flame propagation, then the remaining preliminary air-fuel mixture is successively made to self-ignite and burn with a time lag. The ignition timing is set so that the ratio of the preliminary air-fuel mixture made to burn by self-ignition becomes more than a predetermined lower limit and less than a knocking generation limit.

The door lock with a clutch having a cam-styled axle sleeve according to claim 1 whereinsaid housing of said outer lock part further includes a locking member, and a lock hole of said locking member is provided on a lateral side of said housing; said lock hole is connected on the rear thereof with a lock core rod having a protruding member; said control device includes a pull rod with a spring and a lid with a pair of positioning bars; one end of said pull rod is engaged with said protruding member of said lock core rod, while the other end thereof is connected with said abutting block; in rotating the lock hole with a key, said protruding member of said lock core rod is driven to pluck said pull rod and in turn said abutting block is moved up, so that said cam-styled axle sleeve is apart from said abutting block and to be moved forwards to telescopically connect with said second rotation axle of said inner lock part.3. The door lock with a clutch having a cam-styled axle sleeve according to claim 1 whereinsaid engaging edge of said cam-styled axle sleeve on said rotation axle of said outer lock part is inclined gradually to allow said abutting block to engage said cam-styled axle sleeve for the next time.4. The door lock with a clutch having a cam-styled axle sleeve according to claim 1 whereinsaid gear of said control device is provided with an eccentric protruding block, while said abutting block is provided with a recess for engaging with said eccentric protruding block of said gear.5. The door lock with a clutch having a cam-styled axle sleeve according to claim 2 whereinthe end of said pull rod of the control device that is engaged with said protruding member of the lock core rod is provided as a sheet and on the other end thereof is provided with a positioning block; said abutting block is provided on the top thereof with a positioning groove for engaging with of said positioning block of said pull rod.6. The door lock with a clutch having a cam-styled
