目前对柴油机工作时产生有毒气体的安全稀释程度,常用单个成份毒性之和的方法来确定:(1)当鉴定有害气体毒性时,常把有害物质换算为一氧化碳,换算的普遍式如下:(2)中式——C~(co),一氧化碳的假定浓度;C_(gon)~(co),一氧化炭的允许渡度;C_(gon)~i,第i个成份的允许浓度;C_i废气中第i个有毒成份的浓度。对每一种形式的內燃机,单位时间内有效功率为一马力所产生的有毒气体数量(换算为一氧
At present, the degree of safety dilution of toxic gas generated by diesel engines is usually determined by the sum of the toxicity of individual components: (1) When identifying toxic gases, the conversion of harmful substances into carbon monoxide is often carried out. The conversion formula is as follows: (2 ) - C ~ (co), the assumed concentration of carbon monoxide; C gon ~ (co), the allowable degree of carbon monoxide; C gon ~ i i the allowable concentration of the i component; The i th concentration of toxic components. For each type of internal combustion engine, the amount of toxic gas generated per horsepower per unit of time (in terms of monoxide
