Abstract
The utility model discloses an intake and exhaust structure for cylinder head, which comprises an intake pipe, an intake chamber, an exhaust chamber and an exhaust port. Wherein, a connecting passage with a checkvalve in the middle is provided between the exhaust chamber and the intake pipe or the intake chamber; the checkvalve is positioned at the top of the cylinder head cover with its intake end communicated with the exhaust chamber and its exhaust end communicated with the intake pipe through an exhaust pipe; the connecting passage transmits the exhaust gas into the intake chamber again for the afterburning, thus to make the fuel gas burned more completely with high efficiency and the exhaust gas with little pollution which is more friendly to the environment. The utility model, with its improved checkvalve directly arranged on the cylinder head cover and the secondary intake structure integrated with the cylinder head, lowers the cost; in addition, the reduced cubage of the utility model makes it more simple and practical in designing.
Description
Technical field
The utility model relates to a kind of explosive motor cylinder skull, relates to a kind of cylinder head intake and exhaust structure particularly.
Background technique
In the process that existing motor, mixed gas burn in cylinder, it is insufficient to burn usually, is discharged into atmosphere and not clean-burning waste gas is general direct from relief opening, except causing unnecessary waste, also can cause very big pollution to environment simultaneously.
The model utility content
The purpose of this utility model is at the problems referred to above, a kind of sufficient combustion is provided, pollutes cylinder head intake and exhaust structure little, environmental protection.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cylinder head intake and exhaust structure, comprise suction tude, air-inlet cavity and exhaust cavity, relief opening, between described exhaust cavity and suction tude or air-inlet cavity, be provided with connecting passage, in the middle of this passage, be provided with one-way valve.
Described one-way valve is arranged on the cylinder head tops, and the inlet end of this one-way valve is communicated with described exhaust cavity, and exhaust end is communicated with described suction tude by outlet pipe.
Owing in the middle of exhaust cavity and suction tude or air-inlet cavity, be provided with connecting passage, the waste gas of discharging can be input to air-inlet cavity again and carry out secondary combustion, make that fuel gas buring is more abundant, combustion efficiency is higher, the gas of discharge is little thereby more environmental protection to the pollution of environment.One-way valve after the improvement directly is contained in cylinder head and covers, and secondary air inlet structure and cylinder head are connected as a single entity, no independent secondary air-in device.Save cost, volume must design more simple and practical in dwindling simultaneously.
