Wine-making industry, 一:传统的点火开关 (带锁芯型点火开关) 档位 1 :起动档。 表示:“START或ST(日产、丰田)、或2档(解放)、或Q档(跃进)、或D档(富康)、或AV V档(依维柯)”——起动机电机运转。释放时钥匙会返回ON位置，即为不定位档。 2 :工作档。也叫点火档。表示:“ON或IG(日产、丰田)、1档(解放)、D档(跃进)、M档(富康)、MAR档(依维柯)”——发动机和所有附件运转。这是普通驾驶位置。 3 :附件档。“ACC档(日产、丰田)、3(解放)、A档(富康)——收音机等附件可以操作，但是发动机停止。 如果钥匙在ACC或LOCK位置时打开驾驶员车门，蜂鸣器将鸣叫，提醒驾驶员取下钥匙。 4 :锁定档:“LOCK档(日产、丰田)、0档(解放)、S档(跃进)、0档(富康)、STOP档(依维柯)”——发动机停止和方向盘锁定。只有在此位置才能取下钥匙。 必须插入钥匙将它从ACC扭至LOCK位置。插入钥匙前必须将选档杆设置在“P”位置。一旦取下钥匙，发动机停机装置系统将自动设定。 当起动发动机时，钥匙看上去被卡在了LOCK位置。要将其松开，首先确保钥匙全部插入，然后再慢慢扭动钥匙，同时轻摇方向盘。 5 :预热档:HEAT档(日产、丰田)、4档(解放)、H档(跃进)。该档也为不定位当，该档时加热器工作，为发动机预热～注:当钥匙扭向ACC、ON或START位置时，如果所有仪表的指针轻微移动，不表示故障。点火开关每个挡位都是递进工的，目的是让电器设备逐个进入工作状态，这样还可以缓解由于瞬间通电造成的汽车电瓶的负担。如果着车时在其它挡位不做停留，从LOCK直接进入START的启动状态，会瞬间增加电瓶的负荷，同时由于各电器设备还没有完全进入工作状态，电脑很难正常指挥发动机启动，所以这种操作对电瓶和geographic location Yibin city is located in beautiful rich of "abundance"--Sichuan basin South margin, is located in n 103 ? 39 '-105 ? 20 ', latitude 27 ? 49 '-29 ? 16 ' Zhijian; Yibin East and, Luzhou city, adjacent; North and zigong city development 12th a five years planning platform for into Yu city inter track network planning ( 2011-2030) national and place of related planning, and policy Yibin City tourism development planning Yibin city ease city hold blocking special planning Yibin city related tablets district control sex detailed planning Yibin city public traffic development planning Yibin city land using general planning Yibin city industrial concentrated district layout planning 1.4 planning background Yibin city in sands River, and minjiang River and Yangtze River of Sanjiang intersection at, is China famous of "wine are", belongs to chuan, and Yunnan, and Guizhou three province combined Department area, known as " Yangtze River City, "said, is" in panxi-liupanshui "important part of the resource-rich region.

Wine-making industry, (3)点火开关位于II位置电源总线30与50、15、SU端子接通，使起动机运转;、30与15接通使点火系统分电器等进人工作。因P断电，停车灯不能工作;因X断电，前照灯、雾灯等不能工作。这样就将前照灯、雾灯等耗电量大的用电设备关闭，达到卸荷目的，以满足起动时需要瞬间大电流输入起动机的需要。发动机起动后，应立即松开点火开关，使其回到位置I，切断起动机的电流，起动机驱动齿轮退回。 现代汽车大量采用四档位式点火开关，它具有0、I、II、?(或LOCK、ACC、ON、START)档位，在三档位的基础上增加了一个ACC电气附件元件工作档，其他不变。如图6—48为富康四档位式点火开关工作原理图。 其中: A——电气附件工作位置。点火钥匙位于该位置时，可使用电气附件，此时蓄电池信号灯亮。 M——抿火位置(发动机不起动)。此时下列指示灯亮:蓄电池充电指示灯、驻车和制动液面报警灯、机油压力报警灯、水温报警灯。 D——起动机工作位置。发动机起动后，此时下列指示灯熄灭:蓄电池充电指示灯、驻车和制动液面指示灯、机油压力报警灯、水温报警灯。发动机起动后应立即松开点火钥匙。 2M1，2N1——蓄电池电源人。 2N2，2G2，2Gl，2M2——点火开关输出，控制不同的电路。 geographic location Yibin city is located in beautiful rich of "abundance"--Sichuan basin South margin, is located in n 103 ? 39 '-105 ? 20 ', latitude 27 ? 49 '-29 ? 16 ' Zhijian; Yibin East and, Luzhou city, adjacent; North and zigong city development 12th a five years planning platform for into Yu city inter track network planning ( 2011-2030) national and place of related planning, and policy Yibin City tourism development planning Yibin city ease city hold blocking special planning Yibin city related tablets district control sex detailed planning Yibin city public traffic development planning Yibin city land using general planning Yibin city industrial concentrated district layout planning 1.4 planning background Yibin city in sands River, and minjiang River and Yangtze River of Sanjiang intersection at, is China famous of "wine are", belongs to chuan, and Yunnan, and Guizhou three province combined Department area, known as " Yangtze River City, "said, is" in panxi-liupanshui "important part of the resource-rich region.
