Abstract
Abstract An automotive internal combustion engine demagnetizer that can improve engine performance by reducing the magnetic drag associated with the operation of the engine. By demagnetizing the engine block while the engine is running contributes to improved efficiency and performance. The demagnetizer is designed to be retrofitted onto a standard automobile having a conventional engine. A high current short duration repetitive rectangular pulse passing through the engine block serves to demagnetize it. It also allows metal particles both large and micro in size to stick to the engine block and other moving parts. This collection of particles contributes to engine failure and to the ultimate life of the engine. When the engine is not running, the present invention eliminates or reduces all magnetism in the engine block, causing almost all metal particles to fall into the crankcase that contains the oil. When the oil is drained, these particles are removed and discarded with the oil.
