1. As for the 80cc, in fact there is no such cc bicycle engine in china market, we called our 47*38(bore*stroke) engine F80 before ,but now we correct it, because its displacement is only 66cc(from EPA test report). | |||
2. How to caculate the engine capacity. The fomula is listed below. | |||
The volume of a cylinder=(bore area)x stroke | |||
Bore area= Bore x Bore x pi / 4. (pi has a value of 3.14159) | |||
Take our ZM70-P for example, its bore is 4.7cm(47mm), its stroke 3.8cm(38mm) | |||
4.7×4.7÷4×3.14×3.8=66cc |
