Abstract:
A watercraft includes an improved display arrangement located in a steering operator for steering of the watercraft. The steering operator has at least one hand grip. The display arrangement includes a visual display and a display controller connected to the visual display so as to control the display of watercraft operational information on the visual display. The display controller establishes at least two display modes for the visual display to change the type of operational information displayed. A selector is supported by the steering operator near the grip for easy use by the watercraft operator in changing the display modes of the visual display with the display controller.
Abstract:
An automatic throttle adjustor system for a power boat which is operable to return a carburetor throttle valve to an idle setting from a user-selected setting when a sensor mounted on a bottom of the boat is about to leave the water, and which is operable to return the throttle valve to the user selected setting from the idle setting when the sensor is again submerged in the water. The system includes the sensor, a controller, an actuator, and a throttle linkage. The sensor supplies signals to the controller indicative of whether the sensor is submerged or airborne. The controller uses the signals supplied by the sensor to switch the actuator between a normal, activated state, in which the throttle valve is at the user-selected setting, to a deactivated state, in which the throttle is moved to the idle setting. The throttle linkage includes an element which is in a first position when the actuator is in the activated state and which moves to a second position when the actuator is deactivated. Switching of the actuator between the activated and deactivated states moves the element between the first and second positions and, accordingly, moves the throttle valve between the user-selected setting and the idle setting.
Abstract:
An electronic ignition and engine management system with anti-lockup and anti-kickback features for use in an internal combustion marine engine wherein the engine's operating speed is measured and appropriate ignition advance timing values are determined from the operating speed. An ignition pulse is generated at the ignition advances unless the engine is in a startup mode, or below a predetermined startup threshold speed. During startup mode, ignition pulses are generated at or top dead center to avoid overadvanced firing conditions and thus prevent engine lockup and kickback.
Abstract:
A high-performance outboard motor embodying a V-type four overhead camshaft four-cycle internal combustion engine. A compact cam driving arrangement is provided for driving the camshafts from the crankshaft of the engine at the upper end. A flywheel is mounted to the lower end of the crankshaft and is driven by a starter motor for starting of the engine. Another engine accessory is driven off the upper end of the crankshaft so as to maintain a compact and yet highly serviceable arrangement.
Abstract:
A vehicle speed calculation system capable of calculating a reference vehicle speed of a fourwheel drive vehicle with high accuracy when a fourwheel slip or lock occurs. An integrated value of a longitudinal acceleration is forcedly used for the calculation of the reference vehicle speed when the vehicle is accelerated and a variation of a lowest wheel speed is negative or when the vehicle is decelerated and a variation of a highest wheel speed is positive.
Abstract:
A number of embodiments of jet propelled watercrafts having reverse thrust mechanisms and wherein an indicator is provided for indicating to following watercraft when the watercraft is being rapidly braked or rapidly turned. The watercraft has adjacent throttle and shift lever controls and various control lever positions are disclosed for facilitating ease of operation and compact construction.
Abstract:
In an engine of an automobile, when fuel injection is restarted by the operation of the accelerator pedal from the state in which fuel supply has been cut off during deceleration, fuel injection is controlled according to one of a plurality of fuel injection patterns, which specify a specific cylinder for fuel injection and a specific cylinder for which fuel is not to be injected, and which correspond with various speed change ratios. The engine output torque is kept smooth by performing fuel injection according to that one of these patterns which corresponds to the speed change ratio when the accelerator pedal is operated. Preferably, the fuel injection patterns are determined starting from whichever cylinder initially comes up for fuel injection. Thereby it is possible to attenuate fore and aft vibration of the vehicle immediately after fuel injection is restarted by operation of the accelerator pedal, especially when a direct connection system is provided which has put the engine and the speed change device into the directly connected state during deceleration.
Abstract:
Disclosed is a hydraulic control system of an automatic transmission for an automotive vehicle. The system comprises a hydraulic pump (32); a pressure regulating valve (34); a torque converter (30); a converter clutch regulator valve (36) for actuating a damper clutch; first, second and third solenoid valves (S1; S2; and S3) controlled by a TCU for supplying the hydraulic pressure or obstructing a supply of the hydraulic pressure which is varied in the pressure regulating valve (34) to shift valves of a transmission control section (BB) to displace valve spools of the shift valves; first friction elements (96) commonly actuated at each speed stage; second, third, fourth and fifth friction elements (68; 76; 86; and 90), at least one of which is actuated according to the speed stages; reverse friction elements (98) actuated at the reverse mode; second speed and third speed clutch valves (64; 72) and a fourth speed band valve (80) controlled by ON/OFF functions and duty control functions of the solenoid valves (S1; S2; and S3) for selectively supplying the hydraulic pressure to the friction elements to perform shifting; a reverse clutch inhibiter valve (56) for obstructing a supply of the hydraulic pressure to a sixth friction element (99) to keep the vehicle from malfunctioning when the reverse mode is selected in error while driving forward; and a manual valve (34) operated by a shift select lever for supplying line pressure to a reverse pressure conduit or to a forward pressure conduit.
Abstract:
The liquid pressure controller includes an operating piston directly operated by a mechanical member such as a brake or clutch. An acting piston is connectable to the operating piston and directly acts for producing a liquid pressure of a portion to be operated. A liquid pressure controller connects the acting piston to the operating piston or releases the connection and actuates only the acting piston.
