Abstract: A calculating program based on Excel XP for calculating various parameters was brought forward, with which we can calculate cooler's each construction parameters quickly, repeatedly and accurately, and can analyze the effect each parameters had on performance of the cooler. An EGR cooler was designed for YC4112ZLQ turbo-charged and inter-cooled diesel engine based on EGR cooler's characteristic with experience formulas, and the flow resistance checking calculation was given. Moreover the paper includes plenty of practical calculating formulas and directive parameters of this diesel engine's EGR cooler, such as total heat exchange area S =0.196 m2, heat exchange tube's length L=0.55 m, diameter r=7 mm and its arrangement form.

Key words: internal-combustion engine engineering, EGR, cooler, heat transfer coefficient
