Engine start control apparatus

An engine start control apparatus comprising:

• a float-type oil level detection sensor for generating an oil-level-lowering detection signal by detecting when a level of oil stored in a crankcase of an engine has lowered to a preset lower limit level;
• an ignition circuit for performing an ignition operation by controlling an ignition coil, connected to an ignition plug, to cause the ignition plug to produce a spark discharge;
• and
• a control section for controlling said ignition circuit in accordance with a detection signal output by said float-type oil level sensor, said control section including:
• a first charging circuit comprising a serial connection of:
• a first charging capacitor for charging a reverse voltage produced in a primary coil of the ignition coil;
• said float-type oil level detection sensor;
• and a first diode;
• a first switching element that is turned on, in response to voltage-charging of said first charging capacitor, to disable the ignition operation of said ignition circuit;
• a second charging circuit comprising a serial connection of:
• a second charging capacitor for charging a forward voltage produced in the primary coil of the ignition coil;
• and a second diode;
• and
• a second switching element that is turned on, in response to voltage-charging of said second charging capacitor, to disable an turning-on operation of said first switching element.
