hot efficiency meaning in English
热效率
Examples
- Now design efficiency of common gas boiler can reach 90 percent or so , but various factors such as load , fuel quality , work condition and pressure which result in uncompleted burning of gas and excess air , decrease boiler hot efficiency and cause resources waste and environment pollution . considering these it is essential to adopt closed loop feedback control to boiler burning system
现今,一般的燃气锅炉设计效率均能达到90 %左右,但在实际运行中,因负荷、燃料品质、工作环境、压力、混合情况等因素的影响,往往造成燃气不完全燃烧或空气过量,使锅炉热效率降低,造成能源浪费与环境污染,在这样一种背景下,有必要对其燃烧系统进行闭环反馈控制。 - Engine operating conditions cold be changed quickly and are very bad sometimes , such as : from suddenly cranking to driving in winter , acceleration to sudden torque demand . in the light of zero emission vehicles , in order to achieve better hot efficiency , maximum power , higher safety and best emission , engine controls become more and more difficult . automotive engines are typical nonlinear , time - delay , time - varying parameter systems
汽车发动机使用环境变化大,使用条件有时非常恶劣,从寒冷的冬天突然启动进入行驶状态,行驶过程中的突然加速,急剧的扭矩变化等等,在这样的条件下,为了使其热效率、输出功率、行驶性、安全性和排气清洁性处于最佳状态,给汽车发动机的控制带来了极大的困难,特别是零排放汽车排放标准的提出,对发动机控制提出了更高的要求。
