    摘要： 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.

    摘要翻译： 本发明涉及一种旋流室柴油发动机。 公开了一种具有主燃烧室，涡流室和用于连接它们的连通通道的涡流室柴油发动机。 遇到的问题是，当发动机以低速运转时，涡流室内的燃料液滴将会沿着连通通道聚集并流动进入主燃烧室。 为了防止这种不利的燃料流动，在涡流室内形成凹陷以收集燃料液滴。 凹陷通过圆形边缘邻近并与连通通道连通，以提供一种将使燃烧气体流从凹陷中抽出收集的燃料变得容易的布置。 由于燃料通过燃烧气体流从凹陷中抽出，所以不会发生燃料在凹陷壁上的碳化。

    摘要： A system for forcefully igniting a spray of fuel injected into combustion chambers of a diesel engine during engine starting, in place of a conventional glow plug preheating system. The system comprises a plurality of spark plugs located within the respective combustion chambers of the diesel engine and an ignition means for sequentially igniting each of the spark plugs. The system is operated simultaneously with an engine starter motor and at least until the engine has achieved a spontaneous ignition state or most preferably until a fixed interval of time after the engine has achieved the spontaneous ignition state. Detection of the spontaneous ignition state is based on (a) combustion pressure; (b) engine speed; (c) oxygen concentration; (d) engine starter motor actuation (e) exhaust gas temperature; or (f) engine cooling water temperature.

    摘要： A spark ignition reciprocatory internal combustion engine with dual induction system is provided in which at low and intermediate loads when only a primary throttle valve within a primary induction system opens, a primary intake port passage within a cylinder head will direct fluid charge into a combustion chamber in a cylinder to swirl therein as a primary intake valve opens, while, at high loads when a secondary throttle valve within a secondary induction system opens also, a secondary intake port passage within the cylinder head will direct fluid charge into the combustion chamber in the cylinder in such a direction as to impede and reduce the swirling motion of the fluid charge from the primary intake port passage as a secondary intake valve opens, thereby to maintain the volumetric efficiency of the engine at a sufficiently high level. The secondary intake valve is operated to open in synchronization with the opening of the primary intake valve. The entire combustion chamber is formed by the clearance volume between the upper surface of a piston and the lower surface of the cylinder head and by a cavity formed in the cylinder head.
