摘要： A hydraulic fuse or cut-off device divides fluid flow into: (i) a primary fluid stream; and (ii) a secondary fluid stream having a substantially constant, but small ratio of flow to said primary stream. The secondary stream exerts pressure on a timing piston (7) which thereby monitors the entire flow and causes the fuse to cut-off when a predetermined volume of fluid has passed through the device. The fuse includes a regulating piston (6) for building inlet pressure to a value sufficient to develop the power necessary to drive the timing piston. Greater simplicity of the component parts and decreased sensitivity to contamination results from the use of a small fluid orifice to control the secondary stream. This is achieved by fitting the regulating piston with an inwardly directed flange (9), just touching the peripheral surface of a slightly tapered, central pin (10) whereby the taper of the pin causes the orifice to be created as the regulating piston is caused to slide as a result of the primary fluid flow.

摘要： In a marine fuel system for a fuel injected internal combustion engine, a fitting (50) is provided in the vapor supply line (41). The fitting (50) has a first reduced diameter passage (57) providing a vacuum bleed orifice passage partially venting vacuum from the induction manifold (17) to atmosphere, to limit peak vacuum applied to the vapor separator (33) from the induction manifold (17). The fitting (50) has a second reduced diameter passage (56) providing a flow restrictor passage limiting the volume of flow of fuel vapor from the vapor separator (33) to the induction manifold (17). The fitting (50) limits fuel vapor supplied from the vapor separator (33) to the induction manifold (17) at peak vacuum from the induction manifold (17) during rapid engine deceleration to prevent an overly rich fuel air mixture in the induction manifold (17) otherwise causing rough idling or stalling. The fitting (50) also solves hot restart problems. Another modification is provided by a one-way check valve (60) permitting only one-way flow of fuel from the vapor separator (33) to the high pressure fuel injection pump (25).

摘要： A marine fuel injection system for a two cycle crankcase compression internal combustion engine includes a puddled fuel return line having an outlet in the excess fuel return line from the fuel injector and pressure regulator to the vapor separator and high pressure fuel pump for recirculation. Excess fuel return flow creates a vacuum at the outlet of the puddled fuel return line to suction puddled fuel therethrough for recirculation together with the excess fuel to the fuel pump. The end of the puddled fuel return line at the outlet extends within and parallel to the excess fuel return line to occupy a portion of the cross-sectional area of the latter to reduce such cross-sectional area and create a venturi in the excess fuel return line at the outlet of the puddled fuel return line.

摘要： A marine trolling propulsion system (2) has a lower submerged housing (4) including an electric motor (5) driving a propeller (6) through a reducing traction drive provided by rolling contact of three balls (57-59) between split inner races (36 and 38) and an outer race (60) to drive a transfer member (68) which rotates the propeller (6). The inner race halves (36 and 38) are axially loaded by Belleville washers (72) providing constant axial force with axial deflection, and a limited maximum loading force capability to intentionally provide overload slip protection. The inner race halves (36 and 38) are keyed to the intermediate floating shaft (14) on raised hexagonal shoulders (32 and 34) permitting rocking of the inner race halves (36 and 38) and self-seating and alignement of the inner race halves to the balls (57-59). Couplers (16 and 124) are provided between the electric motor shaft (12) and an intermediate floating axial shaft (14) and between the transfer member (68) and the propeller shaft (70) which enable different axes of rotation to accommodate manufacturing variations. The transfer member (68) is also coupled to the propeller shaft (70) by structure (118, 126, 128) enabling the transfer member (68) to rock about the center of the propeller shaft (70) such that propeller thrust is transmitted equally to the balls (57-59).

摘要： A V-type four-stroke cycle internal combustion engine is providedwith an exhaust manifold (58) disposed in the valley of the V-shaped engine. The exhaust from the cylinders passes through the cylinder heads to an exhaust collection cavity formed in the exhaust manifold (58). The manifold is provided with water pockets (62, 64) above and below the exhaust collecting cavity to cool exhaust collected therein. An air intake manifold is (70) also provided in the valley of the V-shaped engine, located above and adjacent the exhaust manifold. The air intake manifold has a central cavity, with induction tubes (72) extending from the manifold to outside the valley of the V-engine for introducing air to the cylinders therefrom. The induction tubes provide induction tuning to the engine, to increase the torque provided by the engine. The arrangement of the engine components provides compact packaging for a V-type engine.

摘要： An improved exhaust port throttling mechanism for a two-stroke engine. The engine includes a plurality of in-line cylinders (2) each having an exhaust passage (5) disposed to be closed during reciprocating movement of the piston. The exhaust passages (5) communicate with a common exhaust chamber (6a, 6b) and a tubular valve member (10) is mounted for rotation within the exhaust chamber (6a, 6b). The valve member (10) includes a plurality of apertures (13), each adapted to register with one of the exhaust passages (5). When used with a V-6 engine having two banks of in-line cylinders (2), a shaft (12) is connected to each valve member (10) and the corresponding ends of the shafts are interconnected by meshing gear segments (15a-15b). One of the gear segments (15a) is connected through a linkage (27) to the throttle lever (28) for the engine (1) so that the valve members (10) will be rotated by actuation of the throttle lever (28) between a substantially closed position at low speeds, where the valve members (10) substantially close off the exhaust passages, to an open position at high speed where the apertures (13) in the valve members (10) are in full registery with the exhaust passages (5), so that the exhaust gas is discharged via the interior of the valve members (10) without restriction.

摘要： An idling system for a multi-cylinder two-stroke engine as used in an outboard motor. Through a porting arrangement in the carburetor of at least one of the cylinders, the fuel supplied to that cylinder at idle and off-idle speed is reduced to a value so that the fuel-air ratio is too lean to fire. On rapid acceleration from idle speed, a charge of fuel is injected directly to the non-firing cylinder to provide smooth acceleration.

摘要： A knock detection circuit includes an audio transducer (2) converting audio signals indicative of engine combustion into output signal voltage including a portion representing background noise and a portion representing detonation. An active variable resistor is provided by a transistor (14) having a gain which adjusts the amplitude of the transducer output voltage. A sampling and controlling circuit (30, 22, 28) samples the portion of the transducer output voltage representing background noise and outputs a variable bias determined by sensed background noise, which bias controls the gain of the transistor to adjust transducer output voltage inversely with sensed background noise. A detonation threshold detector (58) responds to a predetermined increase in the amplitude of the portion of the transducer output voltage representing detonation above the amplitude of the portion of transducer output voltage representing background noise, and outputs a knock-detected signal. Gated automatic gain control self-adapts and compensates for differing transducer sensitivities providing differing sensed background noise.

摘要： An auxiliary fuel supply system is provided for a two cycle internal combustion engine (302). A first fuel line (350) supplies fuel from the fuel pump (338) to a solenoid (352) which is continuously cyclable between ON and OFF states during running of the engine, including high speed operation where detonation may occur. Fuel then flows through a second fuel line (354) to a restriction orifice metering housing (356), and then to a plurality of third branch fuel lines (358, 384, 386, 388, 390 and 392) for delivery to respective cylinders. The restriction orifices provide a pressure drop from the second fuel line to the plurality of third fuel lines, to provide lower fuel pressure in the third fuel lines, to reduce the chance of leakage at the intake manifold (326), and also to reduce fuel pressure fluctuations in the third fuel lines otherwise due to cycling of the solenoid. Metering housing structure is disclosed. The solenoid is controlled by a variable duty cycle oscillator (408), which in turn is controlled by a fuel enrichment signal (84) output by an electronic control which is responsive to engine knock and/or temperature. Control circuitry is disclosed.
