高原地区的气压低、大气含氧量少、昼夜温差大、气温低、紫外线强、沙尘大等。(1)高原地区对内燃叉车的影响①对发动机的影响。汽缸充气量减少,可燃混合气过浓,燃烧恶化,动力性能和经济性能变差,热负荷增加;高原冷却水沸点降低,导致散热能力下降,热负荷进一步增加;高原风沙大,空气滤清器进气阻力上升快,使用寿命缩短;燃烧室积炭严重,柴油机过早磨损,
Plateau region of low pressure, low oxygen content of the atmosphere, large temperature difference between day and night, low temperature, strong ultraviolet light, dust and other large. (1) Impacts of the plateau on the internal combustion forklift (1) Impact on the engine. The cylinder inflated capacity is reduced, the combustible mixture is too rich, the combustion deteriorates, the dynamic performance and economic performance become worse, and the heat load increases; the boiling point of the plateau cooling water decreases, leading to decreased heat dissipation capacity and further increased heat load; Air intake resistance increased rapidly, shortened service life; serious coke combustion chamber, diesel premature wear,
