摘要： A system and method for facilitating cold starting of a direct injected, two-stroke engine. The engine utilizes a fuel injection system that is controlled to inject a fuel into a combustion chamber just before the piston reaches top dead center, at least during cold starting. This permits better atomization of a variety of fuels to promote dependable cold starting of the engine even when combusting a fuel type such as kerosene.

摘要： Engine control apparatus and methods for avoiding heavy soot production yet providing smooth engine acceleration and deceleration without significant engine RPM increases and decreases with small throttle movements are described. In one embodiment, once the fuel injection angle reaches the angle at which soot formation begins, one or more cylinders are controlled to operate with later injection angles and lower fueling, which results in lower torque production and lower soot formation, while at the same time the remaining cylinders are set to operate with advanced injection angles and higher fueling, which results in a homogenous mixture of air and fuel, higher torque, and also lower soot formation. Therefore, for a first range of throttle positions, all cylinders operate in the stratified combustion mode. When the soot zone is reached, as determined based on throttle position, then some or at least one of the cylinders operate in the homogenous combustion mode and some or at least one of the cylinders operate in the stratified combustion mode. Once all the cylinders have skipped over the soot zone injection angle, then all the cylinders operate in the homogenous combustion mode.
摘要翻译：发动机控制装置和方法，用于避免重质煤烟生产，同时提供平稳的发动机加速和减速，而不会发生大的发动机转速，随着小节气门运动而增加和减少。在一个实施例中，一旦燃料喷射角度达到开始烟灰形成的角度，则控制一个或多个气缸以随后的喷射角度和较低的燃料供应运行，这导致较低的转矩产生和较低的烟灰形成，同时剩余的气缸设置为具有先进的喷射角度和较高的燃料供应，这导致空气和燃料的均匀混合，更高的扭矩以及更低的烟灰形成。因此，对于第一范围的节气门位置，所有气缸以分层燃烧模式运行。当达到烟炱区时，如基于节气门位置确定的那样，一些或至少一个气缸以同质燃烧模式运行，并且一些或至少一个气缸以分层燃烧模式运行。一旦所有气缸都跳过烟灰区喷射角，则所有气缸都以同质燃烧模式运行。

摘要： The present invention, in one aspect, is a pressure responsive valve for a marine engine that facilitates balanced operation of the engine. In an exemplary embodiment, the valve includes a first chamber and a second chamber. Coolant is in flow communication with the valve first chamber, and the engine cylinder head water jackets are in flow communication with the valve second chamber. A flow channel is between the valve first and second chambers, and a plunger is biased to close the flow channel to normally prevent flow from the first chamber to the second chamber. A diaphragm is coupled to the plunger and is responsive to pressure in the first chamber. During operation of the engine at low revolutions per minute (rpm), the pressure of the coolant in the valve first chamber is not sufficient to cause the diaphragm to move the plunger to the open position. As the engine speed increases, the pressure of the coolant also increases. Once the engine speed reaches a sufficiently high rpm so that the coolant pressure exceeds a pre-set pressure, then the coolant pressure in the first chamber causes the plunger to move to the open position. When the plunger is in the open position, coolant flows from the first chamber to the second chamber. As a result, coolant flows through the valve to the cylinder head cooling jackets.
摘要翻译：本发明在一个方面是用于船用发动机的压力响应阀，其有利于发动机的平衡运行。在示例性实施例中，阀包括第一室和第二室。冷却剂与阀第一室流体连通，发动机气缸盖水套与阀第二室流通。流动通道在阀门第一和第二室之间，并且柱塞被偏置以关闭流动通道，以正常地防止从第一室流向第二室。隔膜联接到柱塞并且响应于第一室中的压力。在以每分钟低转速（rpm）发动机运转时，阀门第一室中的冷却剂的压力不足以使隔膜将柱塞移动到打开位置。随着发动机转速的增加，冷却剂的压力也增加。一旦发动机速度达到足够高的转速，使得冷却剂压力超过预设压力，则第一室中的冷却剂压力使柱塞移动到打开位置。当柱塞处于打开位置时，冷却剂从第一室流向第二室。结果，冷却剂流过阀门到气缸盖冷却夹套。
