Abstract
Abstract An ignition system has a burn sensor detects the condition of the burn of the fuel so that the ignition system stops supplying the current to the ignition plug when the burn of the fuel is detected. On the other hand, if the burn of the fuel is not sufficient, the ignition system keeps supplying the current to the ignition plug to make sure the burn to happen. Thus the ignition system can develop the energy efficiency and consumption.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
A multi-ignition system for an automobile comprising: an ignition coil having a primary coil and a secondary coil; a spark plug connected in series to the secondary coil; ignition timing means for providing an ignition timing signal; ignition control means for producing multi-ignition currents in the secondary coil within a time period by means of supplying charging currents to the primary coil intermittently in response to said ignition timing signal; a burn sensor for detecting a condition of burn of the fuel; and stopping control means for stopping supply of the charging currents to the primary coil via the ignition control means when the burn sensor detects the burn in the time period.
Claim 2
Dependent Claim
113 words
A multi-ignition system for an automobile comprising: an ignition coil having a primary coil and a secondary coil; a spark plug connected in series to the secondary coil; ignition timing means for providing an ignition timing signal; ignition control means for producing multi-ignition currents in the secondary coil within a time period by means of supplying charging currents to the primary coil intermittently in response to said ignition timing signal; a burn sensor for detecting a condition of burn of the fuel; and stopping control means for stopping supply of the charging currents to the primary coil via the ignition control means when the burn sensor detects the burn in the time period.
Claim 3
Dependent Claim
19 words
The system of the claim 1 further comprising another ignition coil having a primary coil and a secondary coil.
Claim 4
Dependent Claim
19 words
The system of claim 2 further comprising a control circuit for supply current to the ignition coils in parallel.
Claim 5
Dependent Claim
19 words
The system of claim 2 further comprising a control circuit for supply current of the ignition coils in series.
