The engine start control system has a power supply controller (2) which includes an ignition power supply relay (14) activating an electric component of a vehicle and a central processing unit (11) controlling the ignition power supply relay (14), and a co...

A start control apparatus includes a position sensor (14), a basic start determination processor, and a sensor output determination processor (53), and a start permission continuation processor (55). When a power line for supplying electrical current to th...

The control device (100) includes a control unit (110) such as a microcontroller with an ON output for outputting a control signal to the switch in response to a start command to start the starter. It also has a control holder (120) between the control uni...

An ignition control circuit and method of operation provides a very simple but highly effective prevention of engine reverse rotation upon starting by prohibiting ignition when a reverse rotation situation arises.

In a method of starting an internal combustion engine (1), a combustion energy is generated by combusting a fuel that has been injected into a cylinder (2) in an expansion stroke when the internal combustion engine (1) is stopped. In the aforementioned met...

The method involves detecting the revolution rate of the internal combustion engine (1) being started using revolution rate sensors (7) and changing over from an initial torque control method (4a) without revolution rate feedback to a method (4b) involving...

The impossibility of starting a starter motor by using a non-contact type position sensor for deciding an engine start is eliminated. An engine starting apparatus includes a non-contact type position sensor for detecting the range position of a drive mecha...
