Abstract: An electrical fuel injection system incorporates electromagnetic injectors wired in two groups and which are operated on alternate cycles during low speed and normal operation. With increasing power demands, the fuel injection computer supplies pulses of increasing length to keep the injectors open longer and supply more fuel to the engine. Two trains of timing pulses are initiated by reed switches operated by the distributor, and each is connected to a pair of latch circuits operative to provide timing pulses on one channel through gate devices to one set of injectors and to block pulses on a second channel to the other set of injectors. The subsequent signal from the other reed switch results in a timing pulse in the second channel. These timing pulses are supplied to the fuel injection computer to initiate the injection pulses and to AND gates which also receive the timing pulses.

Abstract: An electronic circuit is described for use with an existing fuel injection system in which fuel control pulses are generated on the basis of air flow rate, engine speed and exhaust gas composition. In particular, the existing fuel injection system is assumed to include an exhaust gas sensor with a signal integrator and a throttle position switch which indicates a closed throttle. It is also assumed that the fuel injection system shuts off fuel control pulses when the throttle is closed and engine speed drops below a predetermined value. The present circuit is intended to recognize this fuel shutoff and to set the integrator at an average value irrespective of the "too lean" signal which it receives from the exhaust gas sensor. In this way, upon termination of fuel shutoff, the engine will receive an average mixture rather than a highly enriched one.

Abstract: A variable expansion ratio internal combustion engine equipped with throttleless induction control and intake valve mechanism operable to induct an ambient pressure charge varying with load demand. Maximum compression pressure is preferably somewhat below that which produces combustion detonation. Constant compression ratio from idling through full load conditions is maintained by varying the clearance volume inversely with load demand. Charge induction at ambient pressure is provided with a throttleless carburetor and is manually controlled by a servo-power operator functioning to synchronize a linkage interconnecting the intake valve mechanism with mechanism for varying the cylinder clearance volume. This linkage operates to variably control closure of the intake valve during the intake stroke or, alternatively, to close the intake valve during the initial phase of the compression stroke.

Abstract: An internal combustion engine in which the longitudinal center line of the cylinders are parallel to and equally spaced around the longitudinal center line of the engine.The pistons, working within said cylinders, are mounted on a swash plate mechanism, by means of which the reciprocating motion of the pistons is translated into the rotary motion of a carrier plate to which the said swash plate is mounted and, from which, is taken the drive into the vehicle transmission.Said swash plate is mounted on a post at the circumference of the carrier plate and pivots around said post when moved, on a longitudinal axis, by a mechanism.As each piston, in turn, passes the point on the swashplate adjacent to the mounting post, it is at the top-dead-center position in its cylinder. As said piston passes the diametrically opposite point on the swash plate it is at the bottom-dead-center position.

The braking device also includes a control member, e.g., a valve spool, common to all control conduits, for selectively connecting the control conduits to and disconnecting them from different driving cylinder-piston units and working cylinder piston units to thereby establish or interrupt connection between different driving cylinder-piston units with different working cylinder-piston units.

Abstract: The engine for which the system provides ignition control produces a basic signal giving the time lapse of a predetermined angle of crankshaft rotation. Leading and trailing edges of this basic signal produce control signals. During the interval between these two a first counter stepped by clock pulses produces a count proportional to engine speed down to a certain relatively low engine speed beyond which overflow of the counter holds the counter at its maximum value. The count so determined is utilized in an ROM as the engine speed parameter which together with other engine operation parameters produce the address that selects the appropriate number to control computed ignition timing.

Abstract: Disclosed is an air-fuel ratio controlling device of an internal combustion engine having on its exhaust system a three way catalytic converter.

The fuel injection device includes an air flow rate meter located downstream of a butterfly valve in the air induction tube. The bearing shaft of the air flow rate meter includes a fuel metering valve which can be activated directly by the air flow rate meter. To correct the air-fuel mixture because of air density downstream of the butterfly valve, the fuel injection device is so arranged, that when the butterfly valve is in its idling and full load positions a rich air-fuel mixture can be regulated, and when the butterfly valve is in a partial load position a lean mixture can be regulated.

Abstract: A fuel injection system for a mixture compressing spark ignition internal combustion engine includes means for injection of fuel into the air intake of the engine. A fuel metering valve dispenses to one or more injection jets a quantity of fuel related to the quantity of air flowing through the intake. An adjustable throttle valve is in the air intake as well as an air flow measuring element which is movable against a restoring force in accordance with the quantity of air flowing through the intake. The measuring element is arranged to actuate a control element of the fuel metering valve. A damping device having a damping element connected to the measuring element is movable to displace fluid between two damping chambers through a throttling passage. One damping chamber is connected to a fuel pump which delivers fuel to the metering valve while the second damping chamber is connected to a discharge port through a thermally controlled outlet valve.

Abstract: A control system for the fuel injection mechanism of an internal combustion engine, especially a Diesel engine. In order to adapt the fuel admitted to the engine to exact requirements, a correction is made on the basis of air mass flow rate and fuel temperature. The air mass flow rate is deduced from signals generated by an air temperature sensor and an air pressure sensor while the fuel temperature is taken by a fuel temperature sensor. The two temperature signals are applied to a bridge circuit which feeds a differential amplifier whose output is mixed with the pressure signal. The composite mixed signal is applied to a servo-mechanism to limit the excursion of the fuel control rack of the fuel injection pump. Status indicators generate feedback signals for comparison with set-point signals to provide closed-loop control.

Abstract: An electronic control circuit incorporated with an AC type ignition system which employs a high-frequency continuous-wave oscillator. The system includes a control winding on a transformer that has a high voltage spark signal output winding. There is a transistor in series with the control winding, to switch on and off a circuit that controls the starting and stopping of the oscillator. And, there are a pair of time delay circuits which produce delay times that are inversely proportional to the speed of an internal combustion engine that uses the ignition system. These time delay circuits may be connected so as to use only one of them. Or, they may be connected in series, so that a desired step timing change may be introduced (or not) upon demand.

Abstract: A switch connected in series with the ignition coil is "on" and "off," respectively, in the presence and absence of a pulse furnished by a pulse generator operating in synchronism with the crankshaft of the engine. If the pulse width of the pulses is too small for the current in the ignition coil to reach the minimum value required for ignition, the closing time of the series switch is advanced, while if the pulse width is too long, causing excess heat dissipation in the coil, the closing time of the switch is retarded. To accomplish this, a first digital counter counts downwards for a predetermined time and upwards for a time period in which the current in the ignition coil exceeds a predetermined current. Upon interruption of the current in the coil, the then-present value in the first digital counter is transferred to a second digital counter. The second counter then counts down at a predetermined rate until a predetermined count is reached.

Abstract: At higher engine speeds the ignition time is advanced by decreasing the time between the breakdown of a threshold element which breaks down for a predetermined amplitude of voltage across the primary winding of the ignition coil and the furnishing of the signal which causes interruption of the primary current. The time is shortened either by decreasing the time constant of the timing circuit connected to the threshold element, or by switching a second timing circuit having a shorter time constant into the circuit at higher engine speeds.
