This utility model discloses an engine cylinder head and its electronic fuel injection system, including a cylinder head body. The cylinder head body has an intake manifold, an exhaust manifold, and a connecting surface for connection and mating with the engine block. The cylinder head body has a fuel jet channel communicating with the intake manifold. A cylinder head fuel jet clearance groove is provided on the inner wall of the intake manifold near the inner end of the fuel jet channel. An intake valve is installed on the cylinder head body, with its valve head installed in an intake valve seat hole. An intake pipe is installed on the cylinder head body on one side of the intake manifold. An injector seat is provided on the intake pipe, and an injector mounting hole communicating with the fuel jet channel is provided on the injector seat. An injector is installed in the injector mounting hole, and the linear distance between the injector nozzle and the center of the valve head is 70mm to 110mm. By precisely defining the position and mating relationship between the components, the overall performance of the engine is maximized.

The application discloses a kind of coal-fired boiler biomass blending combustion feeding system and collaborative control method using existing coal storage facilities, it is related to the automatic control technical field of coal-fired boiler biomass coupling blending combustion, the system includes: acquisition and analysis module acquires the time series data of multiple devices, analyzes fuel stratification information and receives adjustment parameter;Stratification proportioning calculation module accounts for blending ratio, generates basic feeding instruction;Disturbance complex correction module quantifies disturbance and corrects instruction;Variable load collaborative decision module issues fuel feeding instruction in combination with load and storage material;Closed-loop feedback optimization module iteratively updates various parameters according to boiler data and feeds back each module;The application adopts disturbance correction, variable load decision and closed-loop iteration multilayer regulation and control, quantifies various discharging disturbances and corrects feeding instruction, adjusts variable load feeding under working condition, relies on operating data to update parameters autonomously, adapts to working condition dynamic change, reduces manual setting, stabilizes combustion and controls pollutant emission.
