在我国北方寒冷的冬天,经常看到汽车驾驶人员用喷灯烤进气管、油底壳以及加热水、用车拖等办法启动发动机,一台汽车经常需要几十分钟或更长时间才能发动。在高原、低温地区,尤其在海拔四千米以上,如果没有低温启动装置或车辆拖拉,有时竞一整天地启动不了。因而,为了第二天的行车,有些单位甚至整夜使发动机怠速运转。有的驾驶员则夜以继日地行车,常因过度疲劳而发生严重车祸。为了解决高原、低温环境下的启动问题,曾对目前国内外常用的冷启动方法及其附属装置在不同海拔高度和温度下进行了考查试验,如独立式加温器、GYJ-D/G型水加温器(西宁高原工程机械研究所的早期研究产品)、电预热器(日本日产柴油车用)、燃油预热器(国内
In the cold winter in the north of our country, it is common to see motorists burn their intake pipes, sump, and heated water with a torch to start the engine by car towing. A car often takes tens of minutes or more to start. In the plateau, low temperature areas, especially at an altitude of 4,000 meters above sea level, without a low-temperature start-up device or vehicle towing, sometimes competing for an entire day can not start. Therefore, for the second day of driving, some units even let the engine idle at night. Some drivers are driving around the clock, often due to fatigue and a serious car accident. In order to solve the problem of start-up in the plateau and low temperature environment, tests and tests have been carried out on the commonly used cold start methods and their attachments at different altitudes and temperatures, such as free-standing warmer, GYJ-D / G Water heaters (Xining Plateau Engineering Machinery Research Institute early research products), electric preheater (Japan Nissan diesel vehicles), fuel preheater (domestic
