Hybrid power transmission system and control method of online hydrogen production and local hydrogen enrichment internal combustion engine

Abstract

The invention relates to a hybrid power transmission system and a control method of an online hydrogen production and local hydrogen enrichment internal combustion engine. The invention relates to control technology which is cooperatively implemented by combining an internal combustion engine control strategy and a vehicle transmission system control strategy, wherein in the adopted internal combustion engine, gasoline, ethanol, biofuel or a mixture of the gasoline, the ethanol and the biofuel is taken as the fuel, and simultaneously the adopted internal combustion engine timely and quantitatively injects hydrogen to a given position according to the preset control strategy to assist the combustion, so the internal combustion engine can meet the requirement of the whole vehicle torsion and simultaneously can improve the economy and the discharge performance of the whole vehicle by burning thin gas mixture in a compression ratio which is higher than that of the conventional internal combustion engine. Due to adoption of high compression ratio and the thin gas mixture, the ignition type internal combustion engine realizes quick combustion, avoids accident fire, improves the efficiency, and realizes energy consumption reduction and super low discharge of pollution from the source.
