摘要： An electrical signal representative of engine speed is derived; a sensor senses the composition of the exhaust gases and provides an electrical signal to an integrating controller which is connected to adjust the air-fuel ratio applied to the internal combustion engine. In accordance with the invention, a switching circuit is connected to the integral controller which is controlled to switch in synchronism with rotation of the engine to command the integrator to integrate in steps dependent on engine speed so that, as the engine speed changes, the integration rate changes.

摘要： Changes in barometric pressure and/or temperature can adversely affect a number of engine functions. Apparatus is disclosed for controlling and modulating a number of engine functions, including carburetor idle fuel and main fuel supply, fuel enrichment during acceleration and wide open throttle operation, as well as vacuum applied to such vacuum motors associated with the engine as the carburetor choke, the spark advance and automatic transmission shift. Calibration features are provided for establishing a base condition of operation as well as individual calibration of all the various functions listed together with the ability to make base calibration changes by application of an external signal.

摘要： The exhaust gas composition is sensed by a sensor which provides an electrical output signal which is appliied to an integral controller which controls the mixing device (fuel injection system or carburetor) which mixes air and fuel to provide the air-fuel mixture for the engine, in proper proportion for minimum noxious exhaust emission. In accordance with the invention, the integral controller integrates at a rate which is controlled by the speed of the engine. A speed-dependent pulse signal is derived, applied to a monostable multivibrator (MMV) which samples the signal applied to the integral controller, so that the integral controller will integrate only when it receives the sample signal, and hold the then obtained integrated signal until the next sampled signal is applied thereto.

摘要： An exhaust device for a saddle-type vehicle having a pipe section with respect to a vehicle body and housing a catalyzer therein, and a muffler connected to a rear end of the pipe section includes an upstream oxygen sensor disposed on the pipe section and positioned upstream of the catalyzer and a downstream oxygen sensor disposed on the pipe section and positioned downstream of the catalyzer. The pipe section includes a larger-diameter portion having an increased diameter for housing the catalyzer therein. The downstream oxygen sensor is disposed in the larger-diameter portion. The upstream oxygen sensor and the downstream oxygen sensor are positioned upwardly of a central line of the larger-diameter portion with respect to the vehicle body as viewed in side elevation of the vehicle body.

摘要： An altitude fuel limiter and method for controlling an engine using the same is provided. The altitude fuel limiter includes a torque screw sleeve extending from an inboard end to an outboard end. The torque screw sleeve has an interior surface defining a central bore extending axially within the torque screw sleeve. A plunger is disposed within the central bore and moves axially between a first position and a second position. A plunger regulator senses ambient pressure and is coupled with the plunger to axially displace the plunger toward the inboard end of the torque screw sleeve to the first position in response to sensing an ambient pressure that is below a predetermined pressure. The predetermined pressure may be associated with non-compliant altitudes and the plunger limits fuel delivered to the engine when displaced to the first position.

摘要： A vehicle engine automatic control device has a brake operation amount detecting unit that detects an amount of brake operation by a driver, an engine stopping/re-starting unit that, during coast drive, stops an engine based on the amount of brake operation that is detected, and, after the engine stops, re-starts the engine when the amount of brake operation that is detected falls below a first threshold, and a first threshold setting unit that sets the first threshold smaller as vehicle speed becomes lower.
