Abstract: A combined electronic ignition and fuel injection system for internal combustion engines utilizes a non-magnetic disk, attached to the engines shaft and rotates with the shaft, and contains permanent magnet along the periphery of the disk at intervals defined by the shaft's position for each cylinder group. The magnets develop voltage timing pulses within pick-ups coils which are connected to circuits for amplifying and shaping the timing signals. The coil driver switch charges the ignition coil and the spark plugs are then fired, then in another cylinder chamber the fuel injectors are opened, and the fuel is injected into the cylinder chamber. This electronic ignition and fuel injection system is an improvement and a simpler system than that which is usually utilized in internal combustion engines, because it does not require the use of a computer or distributor. It is particularly useful in the rotary-reciprocal combustion engines, and may be used in rotary and reciprocal combustion engines.

Abstract: A compression detection apparatus for determining which one of a pair of phase-opposed cylinders is under compression has a capacitive probe coupled to both ends of the secondary winding of an ignition coil servicing both spark plugs of the pair of cylinders. Phase and magnitude of the voltage signal appearing on the capacitive probe line are processed by a single comparator for determining which on of the pair of cylinders is under compression.

Abstract: An energy-on-demand vehicular ignition system, particularly a coil-per-plug system ("CPP") with a programmable re-striking and minimum single-strike energy output whereby at idle engine speed and lowest load, each coil will be re-struck or discharged the maximum number of times permitted by the coil design within a limited time interval representing the beginning of the combustion event and occurring within 0-2% MFB, and preferably within 0.5% MFB, of the ignitable air fuel mixture within the combustion chamber. The CPP system also includes programmable re-striking whereby the system will default to a single-strike at conditions above a predetermined range of operating conditions, in particular, at a particular engine speed condition and a particular engine partial load condition. In between the conditions at (i) idle engine speed and lowest load on the one hand and, (ii) a predetermined engine speed and partial load condition. The ignition strategy includes the coil being re-struck more than once, but less than the maximum number of re-strikes permitted by the coil design, with the particular number of re-strikes being determined in accordance with a preset schedule as predetermined to be ideal for complete combustion at the operating conditions being sensed.

Abstract: Disclosed is an engine for an automotive vehicle designed such that a mixed gas supplied to the combustion is burned first in the periphery of the combustion chamber and then over the entire length in the peripheral direction of a cylinder, followed by burning the mixed gas in the center of the cylinder. Plural sources of ignition, i.e. ignition gaps of spark plugs, are so disposed at a peripheral end portion of the combustion chambers in spaced relationship with each other in a cylindrically peripheral direction as to allow the flame ignited by each of the spark plugs to coincide or collide with each other in the cylindrically peripheral direction and thereafter in the center of the cylinder. This arrangement can eliminate NOx and HC and perform dilute combustion, thereby improving fuel economy.

Abstract: An internal combustion engine includes fuel injectors which directly inject high pressure fuel into combustion chambers of the engine. Spark plugs are provided in the combustion chambers, a catalytic converter is provided in the middle of the exhaust pipe for purifying the exhaust, and a temperature sensor is provided for detecting the temperature of a catalyst of the catalytic converter. A control unit which receives as input the engine rotational speed, load, and the detection value of the catalyst temperature sensor controls the engine such that, when the temperature of the catalyst is lower than a predetermined target temperature, the fuel injectors inject additional fuel into the combustion chambers during at least one of the expansion stroke and the exhaust stroke to mix the fuel with the exhaust. Thereafter, the exhaust having the additional fuel mixed in is reignited upstream of the catalytic converter to heat the catalyst to the target temperature.

Abstract: The ignition unit includes a support housing containing two ignition coils each for the connection to at least one, and preferably two, associated spark plugs. Each ignition coil comprises a primary winding and a second winding disposed around the end arms of a magnetic core or circuit formed by only two packs of plates juxtaposed so that together they form essentially a figure-of-8 shape. The packs of plates are identical, essentially E-shaped and are placed close together, face-to-face, so that together they form a squared figure-of-8 shape. Each of the packs of plates has a notch which extends from the back of the E into its central arm and almost up to the end of the free end thereof. Conveniently, inserts of non-magnetic material are disposed in the notches in the packs of plates.

Abstract: Upon starting or in the event of a malfunction of the sensor for detecting the stage of the engine, the ignition in the various cylinders is controlled according to a sequence different from that used during normal operation. In the case of engines with odd numbers of cylinders, the sequence is completed in a rotation of the driving shaft through 360.degree. and acts on only one cylinder at a time; in the case of engines with even numbers of cylinders, the sequence is completed in a rotation of the driving shaft through 720.degree. and involves a pair of cylinders at a time.
