摘要： An engine control method generally applicable to those control systems of the engine such as an ignition system, fuel injection system, etc., which are controlled to optimum operation in accordance with the engine operating conditions. In this method, an operation starting timing and an operation ending timing of the control system, e.g., in the case of the ignition system, an ignition coil energization starting timing and an ignition timing (an energization ending timing) are computed at each of predetermined computing cycles, and the latest computed ignition timing, for example, which is computed after the coil energization has been started further taking into consideration of the actual coil energization timing and a minimum required energization period is compared with an ignition timing computed in the preceding computing cycle, and a corrective computation of the latest computed ignition timing is carried out depending on the result of the comparison to obtain an optimum ignition timing. Also the history of the ON-OFF state of a bleed valve in an engine air supply system is monitored. The actual duty cycle of the valve is compared with a desired duty cycle to determine whether or not to open the valve for a succeeding time period.

摘要： A sliding throttle valve type carburetor comprising a sliding throttle valve, an air intake passage and a fuel float chamber, the sliding throttle valve extending along a line of intersection with the intake passage and being disposed at an acute angle relative to the portion of the intake passage upstream from the sliding throttle valve. The sliding throttle valve forms an angle of intersection with the portion of the fuel surface in the float chamber upstream from the sliding throttle valve which is greater than the aforementioned acute angle.

摘要： A carburetor of the constant depression type having a butterfly throttle valve is provided with an auxiliary passage for supplying air directly to the induction passage downstream of the throttle valve when the said throttle valve is in the idling position, opening of the throttle valve beyond the idling position causing the air supply through the auxiliary passage to a position downstream of the throttle valve to cease either due to the edge of the throttle valve moving across the auxiliary passage opening or to the said auxiliary passage being closed.

摘要： A carburetor includes a main body defining a bore, a main passage and a venturi defined within the bore, and a fuel nozzle carried by the main body and including a fuel nozzle outlet communicating with the venturi. The carburetor may also include a valve member translatable across an axis of the bore, such that in a closed state, the valve member closes the main passage but maintains the venturi at least partially open. The carburetor may also include a needle valve disposed at an end of the fuel nozzle substantially opposite of the fuel nozzle outlet to variably control flow of fuel into a fuel nozzle inlet, and a needle valve transmission may be coupled between a throttle shaft and the needle valve to convert rotation of the throttle shaft to translation of the needle valve.

摘要： A carburetor, adapted to supply a lean air-fuel mixture to the main chamber and a rich air-fuel mixture to the auxiliary chamber of a stratified charge internal combustion engine, has an auxiliary induction passage formed as a cylindrical bore. The auxiliary induction passage receives air from the main induction passage through a lateral inlet port. A throttle in the auxiliary induction passage is formed as a hollow cylinder conforming to the cylindrical bore and is axially reciprocable past the port to control flow therethrough. Fuel is introduced into the transfer passage in accordance with air flow therethrough, and idle fuel is introduced directly into the cylindrical bore.

摘要： Embodiments for controlling an exhaust back-pressure valve are provided. In one example, a method for operating an engine comprises closing an exhaust back-pressure valve in response to a component temperature, adjusting intake and/or exhaust valve operation in response to closing the exhaust back-pressure valve to reduce cylinder internal exhaust gas recirculation (EGR), and while the exhaust back-pressure valve is closing, indicating degradation of an exhaust back-pressure system if a designated engine operating parameter remains constant. In this way, degradation of the exhaust back-pressure system may be diagnosed while maintaining combustion stability.

摘要： A carburetor which comprises a casing, an air inlet at the upper end thereof and an air-fuel mixture discharge at the lower end thereof, with a venturi throat located downwardly of said inlet, a sonic throat below said venturi throat, and a diffuser section interconnecting the sonic throat and the discharge. Portions of the wall of the sonic throat are provided with a plurality of indentations, projections, or surface irregularities for stabilizing the flow therethrough and conducing to the uniformity of the air-fuel mixture. At least one portion of said sonic throat is movable with respect to the fixed portions of said throat for altering the cross-section thereof responsive to fuel requirements for combustion.
