摘要： A low pressure, low cost electronic fuel injection system (18) for small hand-held two cycle engines (1) is provided which employs a number of improvements, including by way of example and not of limitation, an improved low cost injector construction (45), a throttle body integration (10) that includes mounting the operational components of the supply system on a single unit, an improved ignition module (40), a pressure regulated fuel system controlled by an electronic control unit (42) employing and an adaptive algorithm based on engine speed which controls the speed by varying the amount of fuel provided to the engine.

摘要： A two-stroke internal combustion engine including a cylinder; and a piston movably mounted in the cylinder. The cylinder includes an exhaust port and transfer ports. The transfer ports include a first pair of the transfer ports disposed closer to the exhaust port than a second pair of the transfer ports which are disposed further away from the exhaust port. The first pair of transfer ports are angled relative to each other at a first angle of about 70° to about 85 ° and the second pair of transfer ports are angled relative to each other at a second angle of about 120° to about 150°. Directional discharge of scavenged air out of the transfer ports 10 establishes a flow path for the scavenged air to minimize losses of the fresh unburned fuel into the exhaust port.
摘要翻译：一种包括气缸的二冲程内燃机; 以及可移动地安装在气缸中的活塞。气缸包括排气口和输送口。传送端口包括设置在更靠近排气口的第一对传送端口，而不是设置成更远离排气口的第二对传送端口。第一对传送端口以约70°至约85°的第一角度相对于彼此成角度，并且第二对传送端口以约120°至约150°的第二角度相对于彼此成角度。被清除的空气从传送口10排出的方向设置了清扫空气的流动路径，以使得新鲜的未燃烧燃料进入排气口的损失最小化。

摘要： A two-stroke internal combustion engine (10) including a cylinder (12); and a piston (14) movably mounted in the cylinder (12). The cylinder (12) includes an exhaust port (34) and transfer ports (36). The transfer ports (36) include a first pair of the transfer ports (44, 48) disposed closer to the exhaust port (34)than a second pair of the transfer ports (46, 50) which are disposed further away from the exhaust port (34). The first pair of transfer ports (44, 48) are angled relative to each other at a first angle of about 70° to about 85 ° and the second pair of transfer ports (46, 50) are angled relative to each other at a second angle of about 120° to about 150°. Directional discharge of scavenged air out of the transfer ports (36) establishes a flow path for the scavenged air to minimize losses of the fresh unburned fuel into the exhaust port (34).
