The purpose of this utility model is that to design a kind of piston be the pin cup internal-combustion engine that cup-shaped, suction port and air outlet are provided with annular slotted hole and rectangular window checkerwork cell in order to overcome above-mentioned deficiency, and simple in structure, the thermal efficiency is higher.
The utility model content, the piston of pin cup internal-combustion engine is cup-shaped, suction port is established on the top of piston, the bottom sets out gas port, the heart cup that is fixed on the cylinder body upper end is provided with the pressurized machine gas storage chamber, and this gas storage chamber is communicated with the air outlet of air throttle, and heart cup bottom is provided with pressurized machine gas storage chamber air outlet; Heart cup bottom is fixed with igniter, is provided with incomplete spherical combustion chamber below at the bottom of the heart cup cup; Piston and eccentric wheel are hinged on the two ends of connecting rod respectively; Eccentric wheel is that spline is connected with transmission shaft; Side at cylinder cap is equipped with suction valve, and the suction port of suction valve is communicated with atmosphere and the air outlet is connected in piston upper end; The opposite side of cylinder cap is provided with air throttle, and the suction port of air throttle is connected in the upper end of piston and the air outlet is communicated with the pressurized machine gas storage chamber; Drain pan is connected through bolt with eccentric roller box, and eccentric roller box is connected through bolt with cylinder body; The suction port of combustion chambers of internal combustion engines and air outlet are equipped with annular slotted hole and rectangular window checkerwork cell.
The drain pan of pin cup internal-combustion engine, eccentric roller box and cylinder body also can be designed to overall structure.
The utility model advantage because the piston of pin cup internal-combustion engine is cup-shaped, is provided with the heart cup that is fixed on the cylinder body in this piston, the side of heart cup communicates with air throttle in being contained in cylinder cap, play the pressurized machine effect, do not need ad hoc pressurized machine, so simpler than existing Structure of Internal-Combustion Engine; Because the suction port and the air outlet of pin cup internal-combustion engine all are provided with annular slotted hole and rectangular window checkerwork cell, suction port and exhaust port area are big, thermal efficiency height.
