摘要： A fuel sensing diaphragm and an air sensing diaphragm apply opposing forces to a transfer member. The forces applied by the fuel sensing diaphragm are based upon the flow rate of fuel, and the forces applied by the air sensing diaphragm are based upon the air flow rate through a venturi. The fuel sensing diaphragm, transfer member, and air sensing diaphragm move together as a control unit which controls the amount of free air allowed to enter an air chamber. Free air in the air chamber is bled off across a vacuum orifice connected to a vacuum port below the throttle plate. The air chamber is in fluid communication with a regulator air chamber. The regulator air chamber is separated from a regulator fuel chamber by a regulator diaphragm and plunger. The regulator diaphragm and plunger operates a fuel inlet ball valve which controls the flow of fuel. A regulator diaphragm and plunger operates the fuel inlet valve based on the pressure in the regulator fuel chamber, the pressure in the regulator air chamber, and the force of a regulator spring. Fuel is discharged through a fuel discharge into an accelerated air stream caused by an air orifice. The mixture of accelerated air and discharged fuel enter the main air stream below a throttle plate. Changes in air density are compensated for by an aneroid chamber regulating the pressure differences on the air sensing diaphragm, which alters the forces the air sensing diaphragm applies to the transfer member.

摘要： In an electronic control apparatus for an internal combustion engine, the contents of a selected reference register are compared with the count contents of a timer so that when equality is found therebetween, an interrupt signal is applied to a central processing unit, which then computes when and how a control condition is to be changed with respect to one of a plurality of controlled systems and the contents of the reference register are updated accordingly. In addition, a plurality of actuators for controlling the operation of the engine are selectively controlled in accordance with control signals generated from the central processing unit on the basis of the receipt of the interrupt signals.

摘要： A manifold depression responsive fuel pump has its fuel outlet connected to an automatic cold start air/fuel mixture supply device, and a movable stop, which limits movement of the pump diaphragm to enlarge the fuel chamber, has its position controlled by the engine temperature responsive thermostatic control mechanism of the cold start device. The pump diaphragm carries a shut-off valve opposite the pump fuel inlet. Fuel is pumped into the cold start device by the pump when the carburetter throttle valve is opened before the engine has warmed up to normal working temperature. The movable stop is moved towards the pump fuel inlet, as the engine warms up, and seats the shut-off valve in that fuel inlet when the engine has warmed up to its normal working temperature so that the pump does not function to pump fuel into the cold start device once the engine has warmed up to its normal working temperature.

摘要： A piston slidably received in a tubular housing is movable in response to the instantaneous flow of intake air to vary the number of small diameter tubes through which fuel can be jetted under the influence of a variable electrostatic force induced by the application of a variable high voltage across an electrode immersed in the fuel upstream of the nozzles and an electrode arranged about and spaced from the tubular housing.

摘要： An air-fuel ratio control system for an internal combustion engine utilizes an oxygen sensor to maintain a 14.5/1 air-fuel ratio at a first location in an intake manifold to an engine combustion chamber. A method and apparatus is disclosed for adding fuel and/or air to the air-fuel mixture at a second location, between the first location and the engine combustion chamber, so that the engine operates at a high economy, low emission point when idling, running at a substantially constant speed or decelerating and operates at a low economy point, yet still with low emissions, only when accelerating.

摘要： A carburetor and fuel feed device for small internal combustion engines incorporating a pumping section which receives fuel from a supply and delivers the required amounts for the range of operation between high and low speed operation with any excess being returned to the source of supply. A control device is employed which permits deceleration from high to low speed operation without flooding by instantaneously preventing the supply of fuel for high speed operation in response to movement of the throttle valve to an idle or low speed position.

摘要： A carburetor for spark-ignition internal combustion engines in which the desired fuel-air mixture is maintained by electronically comparing the temperatures of combustion of two sampling burning jets. One sample is enriched with pure fuel vapor, while the other sample is diluted with pure air. The combustion temperatures of both jets are sensed by electronic means and a constant temperature difference between them is maintained by regulating the fuel-air mixture. The mixture regulation is accomplished by electro-mechanical means.
