一、点火系统工作状态不好
1、 Poor working condition of ignition system
特别冷天由于进气温度低,燃油在汽缸内雾化不好,若加之点火能量不足,其结果就会发生淹缸现象,即过多的燃油积累在汽缸内,超过着火极限浓度而无法着车。
Especially in cold weather, due to the low inlet temperature, the fuel atomization in the cylinder is not good. In addition, if the ignition energy is insufficient, the cylinder will be flooded, that is, too much fuel will accumulate in the cylinder, exceeding the ignition limit concentration and unable to start the vehicle.
应急方法:可拧出火花塞擦掉电极间油污,装复后即可着车。彻底的办法是检查点火系统,排除点火能量低的原因,常见如火花塞电极间隙、点火线圈能量、高压线状态等。
Emergency method: screw out the spark plug to wipe off the oil stain between the electrodes, and start the vehicle after reassembly. The thorough way is to check the ignition system and eliminate the causes of low ignition energy, such as spark plug electrode gap, ignition coil energy, high-voltage wire status, etc.
二、 排气管结冻
2、 Freezing of exhaust pipe
外观特征为雾缸压,供油供电正常,不着车。此种情况容易发生于使用频率特别低的车辆,如家距单位特别近,发动机燃烧后的水汽在排气管的消音器处结冻,短途行驶昨天的冰没化完,又结了今天的冰,时间长了,影响到排气,严重则无法起动。
The appearance is characterized by fog cylinder pressure, normal oil supply and power supply, and no landing. This situation is easy to occur in vehicles with a particularly low frequency of use. For example, the home is very close to the unit, the water vapor after the engine combustion freezes at the muffler of the exhaust pipe, and the ice of yesterday is not melted after a short trip, but today's ice is formed again. For a long time, the exhaust is affected, and it is impossible to start if it is serious.
解决方法非常简单,将车置于暖环境中,冰化了自然可起动。彻底的解决则可及时去跑一下高速,车多跑一下,排气的热量会将冰彻底化掉而排出。
The solution is very simple. Put the car in a warm environment and start naturally after icing. A thorough solution can be to run the high-speed in time. If the car runs more, the heat of exhaust will completely melt away the ice and discharge it.
三、电瓶亏电
3、 Battery loss
其表现特点是起动机开始转但转速不够即无力,后来起动机只咔咔响不转。冬季低温及个别用电设备忘关后会造成车辆无法起动,特别是冬季长期短途低速使用,电瓶电压会低于额定值,起动及无法正常运转。
Its characteristic is that the starter starts to rotate, but the speed is not enough, that is, it is weak. Later, the starter only clicks and does not rotate. Low temperature in winter and forgetting to turn off some electric equipment will make the vehicle unable to start, especially in winter, when it is used for a long time and short distance at low speed, the battery voltage will be lower than the rated value, and the vehicle will not start and operate normally.
若有发生请打服务站救援电话,或找车对一下,或暂时对着火,之后必须到服务站对电瓶补充充电。
In case of any accident, please call the service station for rescue, or find a car to check, or it is on fire temporarily. After that, you must go to the service station to recharge the battery.
四、气门结胶
4、 Valve gumming
冬季用车,特别是用了不清洁的汽油后,汽油中的胶质不可燃烧将积累在进、排气门及燃烧室附近,在寒冷的早晨会造成起动费劲,甚不着火。
When driving in winter, especially after using unclean gasoline, the colloid in the gasoline will not burn, and will accumulate near the inlet and exhaust valves and combustion chamber. In cold mornings, it will cause difficulty in starting and even no fire.
应急方法:可向燃烧室内滴一些机油,一般可起动。起动后到服务站进行免拆清洗,严重的要汽车维修解体清洗缸盖。
Emergency method: drop some engine oil into the combustion chamber, which can generally be started. After starting, go to the service station for disassembly free cleaning. In serious cases, disassemble and clean the cylinder head for vehicle maintenance.
五、汽油流动受阻
5、 Blocked gasoline flow
表现特点为发动机供油管内无油压。此种情况多发生于温度特别低的早晨,是燃油管路长期脏污造成。温度特别低时水与杂物相混使燃油管路不通,结果无法起动。
It is characterized by no oil pressure in the engine oil supply pipe. This situation often occurs in the morning when the temperature is particularly low, which is caused by the long-term dirt of the fuel pipeline. When the temperature is particularly low, water and sundries mix, so that the fuel pipeline is blocked and cannot be started.
应急方法:将车置于温暖的环境,一会儿车即可起动;或者采用清洗油路的办法加以彻底解决。
Emergency method: put the car in a warm environment and start it in a moment; Or clean the oil circuit.
