Abstract
A control system of an internal combustion engine which performs diffusion combustion by compression autoignition on fuel injected in a main injection in at least a partial operating range and which performs stratified combustion by spark ignition using a spark plug on fuel injected prior to the main injection. The control system determines whether or not the diffusion combustion occurs and performs combustion by spark ignition using the spark plug on the fuel injected in the main injection when it is determined that the diffusion combustion does not occur.
Claims6
A control system of an internal combustion engine which performs diffusion combustion by compression autoignition on fuel injected in a main injection in at least a partial operating range and which performs stratified combustion by spark ignition using a spark plug on fuel injected prior to the main injection, the control system comprising:
- a controller configured to:
- determine whether or not the diffusion combustion occurs;
- and
- perform combustion by spark ignition using the spark plug on the fuel injected in the main injection when determining that the diffusion combustion does not occur.
