Ignition or fuel injection control system with auxiliary source

An ignition system or a fuel injection control system to ensure good ignition efficiency is provided with a dedicated auxiliary source separated from a primary system with a separation diode to avoid sudden drop at the ignition or the fuel injection control system due to significant battery drop, taking place as a start-up motor draws larger currents while starting the engine, essentially comprised of:

• an engine 100:
• comprised of an internal-combustion engine using diesel, gasoline engine, natural gas, or methanol as fuel and provided with a start-up motor 101;
• the start-up motor 101:
• comprised of a brush or brushless DC or AC motor, or a power generator with functions of a motor, manipulated by a motor start relay 102 to manipulate the battery source driven start-up motor 101 and further to draw the engine 100 through a transmission 302;
• a start-up switch 103:
• comprised of a mechano-electronic device or a solid-state electronic switching device to manipulate an ignition device and the motor start relay 102 or other car-laden electric devices;
• a primary battery 104:
• comprised of a rechargeable secondary battery or a super capacitor;
• a separation diode 105:
• comprised of a diode, provided between the primary battery 104 and a first rechargeable auxiliary storage 106 to execute one-way conduction of currents from the primary battery 104 to charge the first rechargeable auxiliary storage 106;
• the first rechargeable auxiliary storage 106:
• comprised of a rechargeable battery or a super capacitor, to store power for the primary battery 104, or car-laden power generator or other charging devices;
• being prevented from inverse discharging to the primary battery 104 by means of the separation diode 105;
• alternatively, a limiting impedance 108 comprised of a limiting induction or resistance connected in series is provided between the first rechargeable auxiliary storage 106 and a second rechargeable auxiliary storage 107 to limit the power discharged from the first rechargeable auxiliary storage 106 at the instant of ignition so to allow the full discharge to the ignition device by the second rechargeable auxiliary storage 107 before accepting the charging power from the first rechargeable auxiliary storage 106 through the limiting impedance 108 comprised of the limiting induction or resistance;
• the second rechargeable auxiliary storage 107:
• comprised of a rechargeable secondary battery or a super capacitor to supply instant power to the engine ignition device 109 upon igniting the engine;
• a power generation unit 200:
• comprised of a AC or DC power generator, drawn by the engine and a rear transmission 302 to produce DC output relatively rectified AC, or to forthwith produce DC output;
• a regulation device 201:
• to regulate power outputted from the power generator into power supply that can be consumed by the primary battery 104, the first rechargeable auxiliary storage 106, the second rechargeable auxiliary storage 107 and other loads;
• and
• an engine shaft 300:
• to output engine rpm to drive a load, to couple a front transmission 301 to the start-up motor 101, and to couple to the power generation unit 200 through a rear transmission 302;
• a engine ignition device 109:
• comprised of a mechano-electronic or a solid-state electronic circuit device, or combined thereof, to ignite the internal-combustion engine to keep engine running;
• a fuel injection control system 110:
• comprised of a fuel injection mechanism to execute throttle switching by controlling fuel ejection gap, and a circuit control device to control the fuel injection mechanism by referring to throttle openness, oil temperature, air inlet temperature, IP-ARB signals;
• either or both of the engine ignition device or the fuel injection control system 110 is or are provided as applicable.
