Abstract
The invention relates to a swirl-chamber Diesel engine. A swirl-chamber Diesel engine is disclosed which has a main combustion chamber, a swirl chamber, and a communicating passage for connecting them. The problem encountered is that, when the engine runs at low speeds, fuel droplets within the swirl chamber will gather and flow along the communicating passage into the main combustion chamber. To prevent this unfavorable fuel flow, a depression is formed within the swirl chamber to collect the fuel droplets. The depression is disposed adjacent to and communicating with the communicating passage via a rounded lip to provide an arrangement which will make it easy for the combustion gases flow to draw the collected fuel from the depression. Since the fuel is drawn from the depression by the combustion gases flow, carbonization of fuel on the depression wall will not take place.
