Drift的几种分类
1.ZT: Inertia-Drift
松开油门并利用惯性使车尾甩出的过弯方式(适用于FR车种,适用于120度以上的大弯角).
操作程序如下:1.入弯前加速,入弯时松开油门同时猛切方向盘 2.车子开始滑行后,降档并
加油门,让车辆一边滑行一边出弯 PS:如果只是想小幅度甩一下,可以不降档的!
2.ZT: Breaking-Drift
踩刹车并利用车身重心转移,使车尾甩出的过弯方法(适用条件同上).操作程序如下:1.入
弯时重踩刹车并降档,让车重心前移 2.猛切方向盘使车尾甩出 3.反打方向盘修正进弯角
度 4.保持车速以滑行到可出弯的角度 5.配合方向盘,瞬间重踩油门出弯
3.ZT: Sidebreak-Drift
拉手刹车使车尾甩出的过弯方法(适用于FF车种).操作程序如下:1.尚未到一般的入弯点处
,提早切方向盘,然后拉手刹车使车辆侧滑 2.滑行时立即降档,并保持滑行状态到过弯顶点
PS:驾驶FF车要注意到的,上述第二点说到的滑行状态出现时,一定要保持到过弯处的顶点,
紧记是过弯的顶点,没到顶点的切弯线会因手刹后而产生误点入弯,很难接着第三点 |

OK , I ll try to explain, but I may be wrong. If I am wrong ,correct me PLZ.
there is a sensor, senses the fluid level. when u brake, the force of
inertia will push oil to the front of engine, make a uneven level. The lower
level portion will trigger the sensor. This happens when you dont change ur
oil for a long time or you have a leakage issue.check the level.
If there is enough oil, I will go to a shop to do a further diagnose, and be
prepared to expect something unexpected. |
