ABSTRACT:
A compression ignition engine comprising a fuel injector arranged in the combustion chamber. Fuel containing oxygen is used as the fuel injected from the fuel injector to the combustion chamber. The mean air-fuel ratio in the combustion chamber is feedback controlled to a stoichiometric air-fuel ratio based on an output signal of an O.sub.2 sensor. The NOx, HC, and CO produced at this time are removed by a three-way catalyst.
