唔明 行車時 個轆唔會好似片尾咁fing格.
轆就掂地既 一點地震動就俾地面及避震吸走.
凌空時fing十下 及fing少幾下 點影響行車??

係任何情況, 減磅一定有正面效果, 而係ＵＮＳＰＲＵＮＧ ＷＥＩＧＨＴ減磅出黎既效果仲係倍數既tim....你唔好睇小果３幾ＫＧ
等我又試下分享我見解同大家硏究下。。。。。
一部車裝左輕身鈴跑同一部車裝左重身鈴跑
我會認為裝左輕身鈴跑時起跑用既扭力,收步用既制动力,都會用少Ｄ
均速時兩者一样
重身鈴唯一係滑行時, 會溜得較遠
所以輕、重不做成分別只會係一個完全唔用ＢＲＡＫＥ既情況出現, 但完成相同路程時間都係輕身鈴短Ｄ
e.g. 2 RG1 need to run for 10km (a fixed disctance), A) with light weight rim and B) with heavy weight rim
A) starting from 0km/h and will use less power to speed up (lower fuel consumption) to a fix constant speed, said 60km/h.
B) starting from 0km/h and will use more power to speed up (higher fuel consumption) to a fix constant speed, said 60km/h.
At constant speed, both will have the same consumption.
After running for 9.5km, B) can leave the car slide for the remaining 0.5km (0L/100km fuel consumption), and the speed is slower and slower...till 0km/h to the end point 10km.
but for A), it will only slide after running 9.7km. So, it will slide for 0.3km (0L/100km fuel consumption), and speed below 60km/h till 0km/h to the end point 10km.
Result: both car consume the same amount of fuel
because A) use less at speed up, but "driving" longer (9.7km), but B) use more at speed up, but "driving" shorter (9.5km)
Average speed, A) is higher than B)
because at the last 0.5km, A) has 0.2km still running at 60km/h then slow down while B) is always below 60km/h.
Therefore, no matter how, light weight is always better (either consumption or performance). |
