Device and method for realizing full-throttle operation of internal combustion engine by adding hydrogen

Abstract

The invention provides a device and control method for achieving full throttle valve running of an internal combustion engine through hydrogen mixing and particularly relates to a lean combustion, fuel control and full throttle valve combustion technologies. A combustion information feedback device and a combustion electronic control unit are added to a system on the basis of reserving all parts of an internal combustion engine body. The combustion electronic control unit can control a throttle valve to be fully open when the internal combustion engine runs; the actual torque is the same as the target torque through the adjustment of the fuel injection pulse width; through the adjustment of the hydrogen injection pulse width, the cyclical variation of the internal combustion engine is controlled, so that the internal combustion engine can stably run in a fully open mode of the throttle valve under part of load, the throttling loss at the position of the throttle valve is eliminated, and the thermal efficiency of the internal combustion engine is effectively improved.

Description

technical field [0001] The invention provides a device and method for realizing full-throttle operation of an internal combustion engine by adding hydrogen, and the specific content relates to lean combustion, fuel control and full-throttle combustion technologies. Background technique [0002] The throttle valve of the current spark-ignited internal combustion engine needs to be partially opened under the condition of partial load and idle speed, so as to ensure that the fuel can be stably burned at a certain fixed air-fuel ratio. However, the partial opening of the throttle valve will significantly increase the negative work of the internal combustion engine pump gas, thereby reducing the thermal efficiency of the internal combustion engine under idle speed and partial load conditions. Most of the energy loss of the internal combustion engine under partial load comes from the pumping loss. [0003] The reason why traditional single-fuel gasoline, natural gas, liquefied pet...
