The invention relates to the technical field of internal combustion engines, in particular to a method for improving the loading performance of a supercharged gas engine, the gas engine and application. The gas engine is provided with a gas supplementing pipeline, and when the rotating speed reduction ratio of the gas engine is larger than a set limit value and the rotating speed reduction rate is larger than a set rotating speed reduction rate limit value, the gas supplementing pipeline is started; the amount of mixed gas entering the cylinder is increased. The amount of mixed gas entering the air cylinder is supplemented and increased according to the change condition of rotating speed reduction of the gas engine, and the rotating speed recovery capacity of the engine is improved. According to the method, when the load is suddenly increased, the gas homogeneous with the gas pressurized by the gas compressor is automatically supplemented into the pipeline behind the gas compressor of the supercharger, the gas compressor of the supercharger does not need to be pressurized, the load of the gas compressor of the supercharger is reduced, and the working efficiency of the gas compressor during loading is improved; meanwhile, the gas enters an engine cylinder to participate in acting, the engine power is increased, the instantaneous power of the engine is additionally increased, the speed of a supercharger is increased, and the rotating speed recovery time is shortened.

The invention relates to the technical field of turbochargers, and discloses a premixing type turbocharger and an exhaust pipe, an exhaust gas turbine is arranged at the front end of the exhaust pipe, a premixing assembly is arranged between the exhaust pipe and the exhaust gas turbine, an oil injection mechanism is arranged on the exhaust gas turbine, and the premixing assembly comprises a mixing cavity formed between the exhaust pipe and the exhaust gas turbine; the front end of the exhaust pipe penetrates through and is fixed with the rear side of the mixing cavity. The mixing cavity is additionally formed in the exhaust pipe, when engine exhaust gas is sprayed into the main output gas pipe from the exhaust pipe, low pressure can be generated in the mixing cavity due to the airflow effect, external air can enter the mixing cavity under the differential pressure effect, the air and the exhaust gas are premixed and then enter the main output gas pipe, and then the exhaust gas turbine is pushed; the introduction of the air can also be pressed in through a pressure air source, so that the air mixing amount is further increased, and the introduction of the air increases the total air flow in the exhaust gas turbine, so that the exhaust gas turbine can intervene in work under the condition of less exhaust gas flow.

This invention belongs to the field of motor drive technology, and more specifically relates to a coaxial planetary gear set two-speed dual-motor independent drive architecture and control strategy. The drive architecture includes coaxial drive motors TM1 and TM2, a double-cascaded planetary gear set, and wet friction brake pad mechanisms B1 and B2. Drive motor TM1 drives the wheels through the two-speed planetary gear set mechanism, while drive motor TM2 directly drives the wheels. This achieves high torque and ultra-high vehicle speed with a small size and lightweight design, greatly increasing the overall vehicle energy efficiency. Furthermore, depending on the vehicle's operating speed, when high torque is required at low, medium, and high speeds, drive motors TM1 and TM2 can drive the wheels simultaneously to achieve rapid acceleration. At ultra-high speeds, drive motor TM2 alone drives the wheels.
