Spark generation method and ignition system using same

Abstract

An ignition system providing power and duration controlled ignition spark, comprises a spark controller, first switching energy accumulator, storage capacitor, and second switching energy accumulator with an ignition coil. The ignition system utilizes dual means of switching energy accumulation, internal energy transfer, and three means of energy release to the ignition spark, working in all possible combinations managed by means of the spark controller depending on engine operating conditions, and provides continuous bipolar ignition spark. Spark profile is regulated by means of control signals (2) and (3) based on their frequency, duty cycle, interrelation, and running time.

Description

technical field [0001] This invention relates generally to internal combustion engines, and more particularly to generating a spark for an internal combustion engine. Background technique [0002] Internal combustion engines are well known. During the operating cycle of the engine, fuel and air are drawn into the combustion chamber by the piston moving away from the inlet of the combustion chamber, the fuel is then compressed by the movement of the piston in the opposite direction (toward the inlet), the spark ignites the fuel, The piston is thus forced away from the inlet, and the combustion chamber is then partially emptied by the movement of the piston eventually towards its exhaust port near the inlet end. Although according to the theory of a simplistic ideal, a single spark would consume all the fuel in the combustion chamber in a near-instantaneous manner, in reality this is not the case. [0003] Two prior art ignition systems that are very commonly used are induct...
