The invention relates to the technical field of carburetors, in particular to a racing motorcycle carburetor throttle valve body system based on double-cavity cooperative control, which comprises a carburetor body, first valve shafts and second valve shafts which are symmetrical to each other are rotationally mounted at the centers of the two ends of the inner sides of the two throttle valve assemblies correspondingly, first bevel gears are fixedly mounted at the upper ends of the two symmetrical first valve shafts, and second bevel gears are fixedly mounted at the upper ends of the two symmetrical second valve shafts; a gear box body is fixedly installed at the upper ends of the two throttle valve assemblies, and a synchronous transmission mechanism used for achieving synchronous action of the first valve shaft and the second valve shaft is arranged in the gear box body. By arranging the two sets of symmetrical throttle valve assemblies and the synchronous transmission mechanism, absolute synchronous equal-proportion opening and closing of the first valve plate and the second valve plate of the double-cavity throttle valve can be achieved, the air inflow difference is avoided, and the double-cavity throttle valve is suitable for the high-rotating-speed scene of motorcycle racing.

The invention discloses an ammonia internal combustion engine system coupling tail gas treatment and waste heat utilization and a control method of the ammonia internal combustion engine system. The ammonia internal combustion engine system comprises a fuel supply system, an air supply system, a waste heat utilization system, a tail gas treatment system and an internal combustion engine power generation system. According to the ammonia internal combustion engine system, the combustion power generation module, the tail gas treatment module and the waste heat utilization module are adopted for control, the combustion power generation module achieves safe and efficient combustion of different fuels by controlling the operation mode of the ammonia internal combustion engine system, and the tail gas treatment module achieves clean and low-nitrogen emission by controlling the tail gas treatment mode with different NOx contents. The waste heat utilization module improves the overall energy efficiency of the ammonia internal combustion engine system by controlling three-stage efficient heat exchange. According to the ammonia internal combustion engine system, the purposes of stable and efficient combustion, comprehensive efficiency improvement, clean and low-nitrogen emission and the like are achieved; through the unique control method, the system can effectively adapt to various operation modes of the ammonia internal combustion engine system, and clean, safe and efficient power generation of the ammonia internal combustion engine system is achieved.

The present disclosure related to an air control system (100) for a carburettor of an internal combustion engine The system (100) includes a first Sensor (102) operatively coupled to an accelerator (112) to detect real-time displacement and generate an electrical signal indicative 5 of throttle demand. An electronic control unit (ECU) (108) processes this signal to generate an actuating signal for airflow adjustment based on engine conditions. A throttle control assembly, fluidly coupled to an air intake passage (107), comprises a piston (104) movably disposed within the passage (107) to regulate airflow and an actuator (110) controlled by the ECU (108) to adjust the piston (104) position in real-time. The ECU (108) continuously 0 regulates the piston's (104) position, dynamically modulating airflow into the carburettor in response to the accelerator (112) displacement, thereby optimizing engine performance and efficiency.

This application discloses a fuel supply system for a rock drill. The fuel supply system includes a housing body with a fuel tank inside; a carburetor including a fuel inlet, a fuel return, and an enrichment port, with the fuel inlet connected to the fuel tank; and an exhaust device having a first port, a second port, and a third port connected to a medium chamber. The first port is connected to the fuel tank pipeline, the second port to the enrichment port pipeline, and the third port to the fuel return pipeline. The exhaust device deforms and compresses in response to external pressure, creating a negative pressure state inside. After the external pressure is removed, it expands again. During the expansion process, air and residual fuel are drawn from the carburetor's internal fuel passage through the third port, creating a negative pressure inside the carburetor and drawing fuel from the fuel tank. When fuel is present in the exhaust device, it deforms in response to external pressure, and the fuel in the exhaust device can be compressed and sent to the carburetor through the second port for enrichment.

The invention discloses a general gasoline engine carburetor with a good linear low idle speed function, and relates to the technical field of general engines, the general gasoline engine carburetor comprises a carburetor body, a throttle valve sheet is arranged on the left side of the carburetor body, and a valve sheet screw is fixedly installed at the circle center of the throttle valve sheet; an E-shaped clamping spring is fixedly installed on the left side of the rear end of the carburetor body, a choke valve sheet is arranged on the right side of the carburetor body, a valve sheet screw is fixedly installed at the circle center of the choke valve sheet, a plug is fixedly installed on the right side of the carburetor body, and a pump cover assembly is fixedly installed on the top of the carburetor body. By changing the structure of the throttle valve piece, changing the airflow flowing direction in the idling state and the transition state, balancing the idling state and the transition airflow and improving the oil-gas mixing and atomizing state in the idling state, the idling stability and linearity are improved, an engine can stably run at the lower rotating speed at the idling state, and the engine performance is improved.
