摘要： It is an object of this invention to provide a two-cycle engine which enables the prevention of carbon in the exhaust port, and ensures a minimum reduction in the open area of the exhaust port for a long period of time. This is attained by including a groove or shoulder formed in at a least a portion of the wall of an exhaust passage immediately behind an exhaust port, and extending along the edge of an opening defining the exhaust port to disable carbon to adhere easily to the exhaust port, or prevent any thick layer of carbon from adhering to the exhaust port so that the carbon layer may have only a limited strength and be easily removed.

摘要： A number of embodiments of engine induction system and fuel injection systems for increasing the engine's combustion efficiency by maintaining a desired ratio between the intake system volume between the throttle valve and the intake port and the exhaust gas volume. This requires a close positioning of the throttle valve to the combustion chamber, and thus results in quick throttle response. A fuel injection system injects fuel into the intake passage, and a number of embodiments of buffer valves are employed so as to maintain stability in combustion when blipping the throttle under no-load conditions. In addition, arrangements are disclosed wherein separate throttle bodies are employed but that utilize the fuel rail as a means for connecting all of these throttle bodies together to provide a unitary sub-assembly. In addition, an improved throttle position sensor and associated controls are mounted in close proximity to each other on the throttle bodies in many of the embodiments in order to reduce external wiring and improve signal transmission. In addition, the control system employs an arrangement for compensating for a non-linearity in the output of the throttle position sensor.

摘要： A lubricating oil supplying system for a two cycle engine that includes a reciprocating engine drive lubricant pump and a solenoid controlled bypass valve for selectively delivering lubricant to the engine of by bypassing it back to the inlet side of the lubricant pump to control the amount of lubricant supplied to the engine. The duty cycle of solenoid is increased as the engine speed is decreased and the duty cycle is also decreased when the throttle is opened rapidly so as to insure the proper amount of lubricant flow to the engine under all conditions, both transient and steady state.
