我国寒冷地区分布较广,以柴油机为动力的工程、运输、农机等机械使用广泛,如何使柴油机实现低温快速起动,是多年来人们急于解决的一个课题。 由清华大学研制的PTC热敏陶瓷低温进气预热起动器（专利号2L93212913.7）实现了这一理想,并由北京市瞬发通达技贸公司批量生产。 现介绍如下: 该装置采用独特的半启式储热结构,利用进气管充气系数小于1的特点,轴对称的布置,使气流平顺;发热元件使用“正温度系数热敏陶瓷”（简称PTC）,具有发热量大、效率高、自动恒温和低温起动效果明显;预热时间由温度传感器控制、声光显示,安装使用方便（附
It is a subject that people are eager to solve for many years because of the widespread use in the cold areas of our country, diesel engine-powered engineering, transportation, agricultural machinery and other machinery. Developed by Tsinghua University, PTC thermistor ceramic low temperature intake preheating starter (Patent No. 2L93212913.7) to achieve this ideal, and by the Beijing Instant Mastery technology companies in volume production. The introduction is as follows: The device uses a unique semi-open heat storage structure, the use of inflatable tube inflatable coefficient is less than 1, the axisymmetric arrangement, the airflow smooth; heating element using the “positive temperature coefficient thermosensitive ceramics” (referred to as PTC) , With a large amount of heat, high efficiency, automatic thermostat and low temperature start-up effect is obvious; warm-up time by the temperature sensor control, sound and light display, easy to install
