Combustion enhancement device for internal combustion engine intake system

Abstract

A combustion enhancement device for an internal combustion engine intake system includes a main body for use in the intake piping system of an internal combustion engine. The main body has a pre-defined receiving space with a first shaft hole and a second shaft hole connected to the outside. The first shaft hole allows outside air to enter, while the second shaft hole is connected to the intake piping system of the internal combustion engine and induced to flow by the negative pressure of the engine. An exchange medium housed in the receiving space is a fluid with predetermined combustion activity. A flow guiding component is disposed inside the receiving space and has a plurality of staggered flow guiding holes to provide wetting and crossflow of the exchange medium. The plurality of flow guiding holes together form a multi-stage gas-liquid contact interface, causing a shear flow field and local pressure difference changes when air flows through the first shaft hole. This causes the exchange medium to generate trace amounts of gas phase components at the multi-stage gas-liquid contact interface, and automatically adjusts the output flow rate of the second shaft hole to be introduced into the internal combustion engine according to changes in the negative pressure.
