A combustion chamber unit is fixedly installed in a heat exchanger through a connecting plate, and the fuel preheating combustion chamber comprises a combustion chamber unit communicated with the heat exchanger, and a scavenging port assembly is fixedly installed at the air inlet end of the combustion chamber unit; the heating plug is arranged in the combustion chamber unit and is suitable for igniting fuel; the preheating oil duct is a sealed cavity defined by a connecting plate and a preheating oil duct cover plate and is close to the outer wall of the combustion chamber unit, and an inlet of the preheating oil duct is connected with an oil pipe; an outlet of the preheating oil channel communicates with an inner cavity of the combustion chamber unit and corresponds to the heating plug. The oil pipe assembly of the combustion chamber comprises the oil pipe and the preheating oil channel, so that after fuel enters the preheating oil channel, gas energy generated after the fuel in the heat exchanger is combusted is used for preheating the fuel, the initial temperature of the fuel is increased, exhaust energy is recycled, the ignition difficulty is reduced, and the fuel atomization effect is improved; and meanwhile, the conversion rate of fuel combustion energy is improved, and the device is suitable for various fuels such as diesel oil, gasoline and kerosene.

    本发明涉及一种适用于驻车加热器的燃油预热燃烧室,燃烧室单元通过连接板固定安装在换热器内,包括:燃烧室单元,与换热器连通,进气端部固定安装扫气口组件;加热塞,设置于燃烧室单元内,适于点燃燃料;预热油道,由连接板和预热油道盖板围合成密封的空腔,且贴近燃烧室单元外壁,预热油道进口连接油管;预热油道出口与燃烧室单元的内腔连通,且与加热塞对应。本燃烧室的油管组件包括油管和预热油道,使得燃料进入预热油道后,利用换热器内燃料燃烧后产生的气体能量对燃料进行预加热,提高了燃料的初始温度,既回收了排气能量又降低了点火难度,改善了燃料的雾化效果,同时提高了燃料燃烧能量的转化率,适用于柴油、汽油及煤油等多种燃料。
