Abstract
The utility model discloses a cam type cylinder head arranged at the bottom of the engine. The utility model is characterized in that the assembly angle and joint distance between intake gate base (2) and exhausting gate base (3) are changed. Sphere radius, total height of a combustion chamber in the cylinder head (1) and assembly angle of a spark plug (14) are changed as well. The installation height 2 of an intake gate conduit (4) and installation height 3 of an exhaust valve guide are seating diameter, seating height of the intake gate (6) and seating diameter, seating height of exhausting gate (7). The utility model increases discharge capacity of the engine to 200 ml. coordinate positions CG125 (150) of positioning pin and bolt hole of the cylinder head are equal. The positioning pin and the bolt hole are arranged on original 125 (150) crank box. Other components need not remolding. With simple structure and low cost, the utility model increases the discharge capacity of the engine to 200 ml.

The utility model belongs to the petrol engine field, particularly a kind of engine lower cammingly cylinder head device that is used for 200ml.
(2). background technique
At present, the underlying cam engine has only 125ml and 150ml discharge capacity.The motor of the big discharge capacity of 200ml does not have the underlying cammingly.The engine price costliness of the above big discharge capacity of existing 200ml on the market, the cost height.
(3). summary of the invention
The purpose of this utility model provides a kind of underlying cammingly cylinder head of the 200ml of being used for motor.It is simple in structure, and cost is low,
For reaching above-mentioned purpose, of the present utility model being characterised in that: the discharge capacity of motor is 200ml; Suction valve cone, exhaust valve seat, intake valve conduit, exhaust valve guide are assemblied in respectively on the cylinder head, and suction valve cone and intake valve conduit angle of assembling α are 26 °, and exhaust valve seat and exhaust valve guide angle of assembling β are 29 °, and 1. the intersection point distance is 18～20mm; 10. the radius of a ball of firing chamber is 34～36mm in the cylinder head, and total height (11) is 18～20mm, and spark plug angle of assembling γ is 32.5 °; 2. intake valve conduit setting height(from bottom) is 81～83mm, and 3. the exhaust valve guide setting height(from bottom) is 81.8～82.3mm; 4. the intake valve diameter of taking a seat is 30.5～31.5mm, and highly 5. take a seat is 31～32mm; 6. the exhaust valve diameter of taking a seat is 26～27mm, and highly 7. take a seat is 32.8～34mm; Outer spring is positioned on the internal and external spring seat in the valve, cooperates two lower shake-changing arms of assembling by valve collet on the lower shake-changing arm axle, cooperates to be installed on the cylinder block again, is fixed on the cylinder head through the spring seat of honour by bolt cylinder.
The utility model is because the coordinate position and the CG125 (150) of the positioning pin hole of cylinder head, bolt via hole are basic identical, be installed on 125 (150) the former crankcases, other part does not need die sinking again, and the discharge capacity of motor can be risen to 200ml, therefore have simple in structure, the characteristics that cost is low.
Below in conjunction with accompanying drawing the utility model is described further.
