Abstract: Some embodiments of the disclosure provide an air intake bypass recirculation structure with adjustable air entraining amount and controllable broadband noise which includes main body of the air intake bypass recirculation structure and an air entraining amount adjusting structure. In some examples, an air intake bypass recirculation cavity is formed in the main body of the air intake bypass recirculation structure. An air inlet of an air intake pipe and an air outlet of the air intake pipe are formed in two ends of the main body of the air intake bypass recirculation structure respectively. An airflow inlet of the air intake bypass recirculation structure and an airflow outlet of the air intake bypass recirculation structure are formed in the inner side of the main body of the air intake bypass recirculation structure. The air entraining amount adjusting structure is arranged in the air intake bypass recirculation cavity.

Abstract: A turbocharger air intake silencer with adjustable cavity space structures is provided. The turbocharger air intake silencer comprises a silencer connecting flange and a first resonator device. The first resonator device comprises a first silencer sealing plate, a first annular sound absorption cavity body, a first rotary table, a first rotary steering gear and a first valve. A first sound absorption cavity is enclosed by the first silencer sealing plate, the first annular sound absorption cavity body, the first valve and the first rotary table. A first sound absorption cavity inlet pipe is arranged beside the first sound absorption cavity. The first sound absorption cavity and the first sound absorption cavity inlet pipe form a Helmholtz resonator. The first rotary steering gear is mounted on the silencer connecting flange. The rotary steering gear is connected with a first rotary rack.

Abstract: A fully variable valve train with a rotary plunger for an internal combustion engine. A motor actuates a high-pressure oil injection pump; when a timing driven electromagnetic valve connected to an oil inlet is opened, high-pressure oil enters a hydraulic cylinder; and when the force applied to a plunger by the hydraulic oil is larger than the force of a valve returning spring, the plunger is pushed to move down, so that a valve is opened. When the valve is required to be return, the timing driven electromagnetic valve connected to the oil inlet is closed, and the timing driven electromagnetic valve connected to the oil inlet is opened; the valve moves up under the action of the valve spring, pushing the plunger to move up and thereby discharging the low-pressure oil out of the hydraulic cylinder, then the plunger and the valve return to the initial positions.
