ABSTRACT:
An internal combustion engine comprising an auxiliary chamber connected to a main chamber via a connecting passage. A raised portion is formed on the inner wall of the auxiliary chamber. The auxiliary chamber is divided into a first chamber and a second chamber. The connecting passage is tangentially connected to the inner wall of the second chamber at a position opposite to the raised portion with respect to the axis of the auxiliary chamber. A fuel injector having a pair of injection nozzles is arranged in the first chamber. One of the injection nozzles is directed to the tip of the raised portion. The other nozzle is directed to the inner wall of the auxiliary chamber, which is located at a position opposite to the raised portion with respect to the axis of the auxiliary chamber. The fuel is always injected from the nozzle towards the tip of the raised portion independently of the operating condition of the engine, while the injecting operation of the other nozzle is started when the load of the engine is increased beyond a predetermined level.
