汽车冷车启动汽油味大的原因: 1、在外界温度很低的条件下,当水温和排气管温度比较低,再加上冬天行驶时发动机冷车启动时外界的温度过低,这时的混合器比较浓,所以有部分混合器不能充分燃烧,直接由排气管排出,所以会闻到一些较浓的汽油味。这应该是正常的。2、还有可能是因为碳罐或碳罐电磁阀出现问题,造成启动时混合气过浓。3、如果当地的气温比较低再加上发动机内部积碳过多,造成混合气雾化不好,也会导致这种现象的发生。4、如果电磁阀一直处于关闭状态,那么碳罐内的汽油蒸汽会越聚越多,最终充满整个碳罐,其余的汽油蒸汽只能逸入大气中了,也会出现汽油味。5、喷油嘴有渗漏的现象,从而导致混合气过浓,未燃烧的混合气就会从排气管排出,因此导致汽油味大。
