    摘要: A method and apparatus for the precombustion identification of a cylinder undergoing compression in an internal combustion engine is disclosed. An electrode gap (e.g., preferably a spark plug) is disposed within a cylinder of an internal combustion engine. The electrode gap is provided with a voltage differential from a power supply through a circuit (preferably an RC circuit). The engine is cranked, and the voltage differential across the electrode gap is monitored during the cranking of the engine. With appropriate choices of the voltage differential across the electrode gap, the resistance R of the circuit, and the capacitance C of the circuit, voltage pulses are produced across the electrode gap during such time when the cylinder is not undergoing a compression stroke. Such voltage pulses are suppressed when the cylinder is in fact undergoing a compression stroke due to a rise in the breakdown voltage across the electrode gap, in accordance with Paschen's Law. The presence or absence of the voltage pulses is preferably converted into a binary output that is indicative of the occurrence of a compression stroke in the cylinder being monitored.

    摘要: A method and electrical system for detecting and compensating for a failure in a starter circuit that comprises first and second relays in a circuit path to a starter motor of a vehicle. The method and system determine if at least one of the first or second relays is in a closed position when it should be in an open position and disables a vehicle starter operation if it is determined that at least one of the first or second relays is in the closed position when it should be in the open position. The vehicle starter operation could be a stop-start operation of the engine.
