Принадлежит: Individual

The present invention is a Universal Automotive Ignition Pickup Assembly that produces an ignition secondary voltage waveform that can be monitored by an oscilloscope or microprocessor. This is accomplished with a sensing probe that can be capacitive coupled; inductively coupled; or capacitive and inductively coupled at the same time. Due to the ability of a pickup to be capacitive and inductive at the same time, the ignition voltage waveforms are clear and concise from secondary ignition wires to a multitude of different ignition coil types.

Method for Igniting a Fuel-Air Mixture of a Combustion Chamber, Particularly in an Internal Combustion Engine by Generating a Corona Discharge

Номер: US20120260898A1
Автор: Torsten SCHREMMER
Принадлежит: BORGWARNER BERU SYSTEMS GMBH

The invention relates to a method for igniting a fuel-air mixture in an internal combustion engine. An electric transformer excites an oscillating circuit connected to a secondary winding of the transformer. A capacitor is formed by an ignition electrode together with the wall of a combustion chamber through which it extends. The excitation of the oscillating circuit is controlled by generating a corona discharge igniting the fuel-air mixture. Before each ignition time the voltage applied to a primary winding of the transformer is incrementally increased, and the intensity of the current flowing in the primary winding is measured repeatedly at the same primary voltage. The variation of the values of the related primary current is determined, and the incremental increase in the primary voltage is aborted at a value thereof at which the variation of the primary current intensity reaches or exceeds a predetermined limit.

Methods and systems are provided for addressing pre-ignition that may be induced in response to actions taken to mitigate a cylinder misfire. An amount of engine load limiting applied may be adjusted to reduce the likelihood pre-ignition while also addressing component over-temperature issues. By limiting an engine load while shutting off fuel in a misfiring cylinder, and while combusting a lean air-fuel mixture in the remaining cylinders, pre-ignition induced by the misfire-mitigating lean combustion conditions can be reduced.

A voltage transformer circuit is described for supplying a spark plug with ignition energy and for ionic current measurement. A transformer of the circuit generates a secondary voltage from a primary voltage and applies the secondary voltage to the spark plug to ignite an electric arc. Using a current effected by the secondary voltage, a capacitor is charged to a breakdown voltage of a Zener diode bridging the same, via a first branch, which leads from the transformer to a first of two sides of the capacitor. The primary voltage is disconnected from the transformer in order to extinguish the electric arc.
