摘要： A dual-chamber type prefilled syringe comprises a cylindrical body within which a front plug member, a middle plug member and an end plug member are hermetically fitted to form a first chamber and a second chamber. The cylindrical body (2) has an inner surface formed with a bypass (14). When the middle plug member (7) moves to a position where the bypass (14) is formed, the first chamber (9) is communicated with the second chamber (10) for the first time via the bypass (14). In this beginning state of liquid transfer (S), an inner volume (VS) of the cylindrical body (2) between a leading end (2a) of the cylindrical body (2) and a rear end (6b) of the front plug member (6) is set to be at least 60% of a volume (VC) of a second component (12). When liquid component within the second chamber flows into the first chamber, it is possible to prevent part of the liquid component from passing through the first chamber to reach a portion for attaching an injection needle at a leading end of the cylindrical body.

摘要： A number of embodiments of direct injected V-type outboard motors provided with a very effective fuel supply system wherein the number of components can be significantly reduced as well as the elimination of many of the flexible conduits normally employed. This also permits the fuel system to be assembled as a relatively unitary assembly that can be then affixed to the engine. The arrangement is such that purging of the system from vapors during shutdowns is easily accomplished and the system can be purged without complicated construction. Furthermore, the system can be pressure tested by an arrangement where the low pressure system can bypass the high pressure system when the engine is not operating so as to be pressurized for testing purposes. However, when the high pressure system operates, then the bypass line will be closed by the shunting valve arrangement. The direct injection system permits operation with two cycle engines even under low load and speed conditions by using residual gasses to assist in fuel vaporization.

摘要： The invention provides an improved oil injection lubrication system for two-cycle engines. The system includes a variable output oil pump, the output of which can be varied in relation to the throttle level. The system also includes a solenoid valve unit containing a plurality of solenoid valves that further regulates the flow of oil from the oil pump to each cylinder. An electronic control unit sends control signals to the soleniod valve unit to regulate the flow of oil based upon engine operating conditions in accordance with a controle scheme. The combination of the variable output oil pump and the solenoid valve unit enables the solenoid valves to be activated with a lighter duty cycle, which reduces the amount of power consumed by the solenoid valve unit.

摘要： A control system for a multicylinder direct injection engine determines a control variable for each cylinder based on engine speed and engine load. The control variable can be altered depending upon an operating temperature of each cylinder independently of the others. The operating temperature of each cylinder is monitored through a temperature sensor disposed on the fuel injector nozzle. The cylinders having nozzles operating at a temperature lower than a normal temperature or normal range of temperatures can have the control variable altered to increase the power of that cylinder and the temperature of that cylinder. The cylinders having nozzles operating at a temperature higher than a normal temperature or normal range of temperatures can have the control variable altered to lower the operating temperature of the nozzle.

摘要： A feed back control system and method for direct injected engines useful in a start up operation that utilizes a fuel pressure condition sensor. At the commencement of cranking, the feed back control system adjusts at least the initiation of fuel injection based upon the output from the fuel pressure condition sensor. This removes a great shift in the fuel pressure between before and after starting of the engine and eventually promotes operator's feeling and also improves exhaust emissions.

摘要： Several embodiments of combustion chamber configurations for direct injected engines having a substantial recess in the cylinder head in which the fuel injector is positioned and injects. The injector is arranged so as to be disposed over the exhaust port and to spray toward the auxiliary scavenge port. However, the spray pattern is such that fuel will not impinge upon the cylinder head surface and so that the scavenge flow will direct the fuel away from the cylinder walls and toward the head of the piston for cooling and better vaporization. This also ensures that fuel will not pass out of the exhaust port.
