Engine controlled by combustion reaction path and regulating method thereof

Abstract

The present invention discloses a novel engine controlled by combustion reaction path, which cylinders comprise working cylinders and reforming cylinders. According to the operational condition of engine, the engine is used for compressing, heating and reforming the fuel injected from the reforming cylinder injector; by controlling the reaction boundary conditions between fuel and air, the reforming cylinder can exhaust partial intermediate products or oxidation products of the different oxidation stages; the products are then mixes with the inlet air in the pre-mixing chamber and then is introduced into the working cylinder. Under operating in different working conditions, the engine can discharge the mixed gas with different activities under different oxidation stages by regulating the corresponding boundary conditions of the reforming reaction of the reforming cylinder, and can achieve concentration stratification and activity stratification of the mixed gas in the working cylinder by using the fuel injected from the working cylinder injectors, and can effectively achieve high effectiveness and broaden the scope of clean combustion by changing the combustion reaction path. The present invention just adopts simple oxidation reaction post-treatment device, and then the emission of the engine can meet the requirement of EuroVI emission regulation.
