Gerak-Gerik Piston

Post by Rydos »

Hai.. Bros s'mua
Minta bantuan'nya donx.
Ada 3 hal yang belum gw ngerti tentang cara kerja mesin motor kita.
Jadi tolong'in gw ya..
1. Gimana sich cara piston untuk bisa bergerak naik turun? (gerakan turunnya udah agak ngerti, tapi naik'nya yang masih ga ngerti)
2. Gimana Cara'nya utk menambah rpm mesin? (Selain ganti CDI)
3. Apa sich fungsi kruk as?
Thank's yang uda ngebantu'in

Wah..
ini rada ribet sih jelasinnya..

1. Piston naik turun karena adanya poros engkol yg menciptakan gaya inersia. piston bs naik krn ada tekanan balik dr kruk as yg vakum.

2. kalo yg ini ini banyak caranya antara lain memperbesar lubang2 inlet-outlet disilinder, sampai ganti magnet ke yg lbh enteng bobotnya.

3. Kruk as/bandul merubah gaya naik turun piston menjadi gaya putar yg dihubungkan dgn stang piston. gaya ini disebut dgn gaya inersia. dari kruk as yg berputar tsb mengubahnya menjadi gaya gerak mesin yg dihubungkan melalui gigi2 dan akhirnya ke roda yg dihubungkan melalui rantai atau kopel.
