  • Patent number: 5074263
    Abstract: A system which includes spark control and fuel charge injection features is disclosed. The spark control feature includes an actuator coupled to distributor points and a switch which controls energization of a coil. A throttle operates the switch. When the throttle is in an idle position, the coil is de-energized, and the engine stops running. The engine is restarted by energizing the coil and causing the actuator to operate points so that spark is produced in a last-encountered cylinder. The last-encountered cylinder contains a fuel charge, and the spark ignites the fuel charge to turn the engine over, causing the engine to start. The fuel charge injection feature includes an accumulator which is fed from the same high pressure fuel lines which feed fuel injectors while the engine is running. A valve traps pressurized fuel within the accumulator while the engine is stopped. Immediately prior to starting the engine, the valve opens causing pressurized fuel to enter the high pressure fuel lines.
