123179500 | Control of spark ignition during starting | 9 |
20080314349 | Green start engine control systems and methods - A method of starting an engine having a fuel rail, one or more fuel injectors, and one or more spark plugs. In one embodiment, the method includes initializing a starting operation of the engine and suppressing the engine from starting by retarding a spark timing of the one or more spark plugs from normal spark timing. The method also includes purging, while the spark timing is being retarded, the fuel rail of the engine by operating the one or more fuel injectors. Additionally, the method includes advancing the spark timing after a first duration has passed or the engine has started. | 12-25-2008 |
20090050093 | Twin Ignition System - A twin ignition system for automotive vehicles and the like is disclosed and claimed. Ignition system # | 02-26-2009 |
20100319645 | Split-type auxiliary power combustion and emergency starting system - The present invention is an installation of an emergency starting switching device and/or direct current boosted boost circuit device. When the power of the starting battery is insufficient, the electric energy of the power storage device battery is used to drive the starting motor in order to start the engine by operating the emergency starting switching device. And when the engine is started, the voltage of the ignition device or the fuel injection device is stepped up to strengthen its starting capability by means of a voltage boost by the direct current boosted boost circuit device. | 12-23-2010 |
20110107993 | METHOD AND DEVICE FOR STARTING AN INTERNAL COMBUSTION ENGINE - In a method for starting an internal combustion engine having at least one combustion chamber, an injection timing point is specified for each chamber at which a first fuel injection pulse is carried out and an ignition timing point is specified at which a first ignition pulse is to be carried out in the chamber. A crankshaft is caused to rotate by a starter device. For all chambers in which the injection timing point takes place in time after the ignition pulse, the respectively specified ignition timing point is adjusted in terms of reduced torque output. Thereafter, in each combustion chamber the injection pulse is carried out at the respectively specified injection timing point and the ignition pulse is carried out at the respectively specified ignition timing point. In this way, any potentially present fuel residue is combusted and at the same time the torque produced thereby is reduced. | 05-12-2011 |
20120060786 | STARTING CONTROL UNIT AND START COMMAND SIGNAL GENERATION APPARATUS THEREFOR - A starting control unit integrally includes a current suppression resistor connected in series with an output contact of an electromagnetic shift relay provided on a starter motor, a short-circuiting relay that short-circuits the current suppression resistor with a short-circuiting contact thereof, and a timer circuit that closes the short-circuiting contact at a predetermined time instant when a starting current decreases in response to the operation of a starting command switch. An excitation coil of the short-circuiting relay is supplied with electric power directly from a vehicle battery by way of one of the terminals of the current suppression resistor, a reverse connection protection device, and a driving transistor, excluding the starting command switch. A suppression starting current for the starter motor flows in the current suppression resistor during the time period obtained by adding a delay setting time T | 03-15-2012 |

20130340698 | BATTERYLESS ENGINE STARTING SYSTEM - A system for starting an internal combustion engine without assistance of a battery uses a pull-start assembly to generate electricity and store the generated power in one or more capacitors electrically connected to an electronic control unit via a permanent magnet alternator. The system includes a hand pump for manually forcing a portion of liquid fuel into an air/fuel mixture chamber while an air relief valve connected to an air injector is open. By closing the relief valve and activating the pull-start assembly, the user causes the fuel into the combustion chamber, where the ignition process is initiated upon receipt of a control signal from the electronic control unit. | 12-26-2013 |
20140007833 | SPLIT-TYPE AUXILIARY POWER COMBUSTION AND EMERGENCY STARTING SYSTEM - The present invention is an installation of an emergency starting switching device and/or direct current boosted boost circuit device. When the power of the starting battery is insufficient, the electric energy of the power storage device battery is used to drive the starting motor in order to start the engine by operating the emergency starting switching device. And when the engine is started, the voltage of the ignition device or the fuel injection device is stepped up to strengthen its starting capability by means of a voltage boost by the direct current boosted boost circuit device. | 01-09-2014 |
20150047593 | METHOD FOR STARTING A COMBUSTION ENGINE HAVING A STARTER APPARATUS - A method is for starting a combustion engine having a pull-rope starter. A fuel/air mixture is fed to the engine via an intake channel. The mixture is ignited by a spark plug. The combustion drives the piston downward and drives a crankshaft rotationally. The fuel system has a fuel channel opening into the intake channel. An electric fuel valve is open in its currentless state and closes a fuel channel only when an operating voltage is applied. An electronic control unit actuates the fuel valve and triggers an ignition spark and is utilized by a generator to supply energy to the control unit, the fuel valve and the ignition device. To prevent excessive enriching of the fuel/air mixture during starting, the energy, which is generated at the beginning of the rotation of the crankshaft, is used to first close the fuel valve before the control unit triggers an ignition spark. | 02-19-2015 |
