This paper is about 490 diesel engines overall designs, is mainly to 490 diesel engines main motion parts designs as well as some servosystems brief design. Through the thermal design, the power computation as well as other theoretical calculation obtain 490 model diesel engines some performance curve, and carries on the reasonable components design according to the performance, thus causes 490 diesel engines to have a better economical performance and the power performance. This article besides includes design of crank link motion gear, but also includes design of air admission and exhaust system, design of fuel oil transportation and injection system, design of cooling system, design of lubrication system.Key words: 490，diesel engine，design，thermal calculation, dynamic calculation目錄摘 要IAbstractII第一章前言31.1 研究目的和意義31.2 國內(nèi)外研究現(xiàn)狀31.3 研究內(nèi)容和方法4第二章柴油機的總體設(shè)計52.1 柴油機的總布置52.2 柴油機的總體設(shè)計7第三章結(jié)構(gòu)設(shè)計113.1 機體組113.2 活塞連桿組143.3 曲軸飛輪組20第四章 內(nèi)燃機輔助系統(tǒng)設(shè)計234.1 配氣系統(tǒng)的設(shè)計244.2 燃油供給系統(tǒng)設(shè)計264.3 潤滑系統(tǒng)設(shè)計284.4 冷卻系統(tǒng)設(shè)計304.5 起動系統(tǒng)設(shè)計33第五章結(jié)論與建議345.1490型柴油機設(shè)計結(jié)論345.2 對于490型柴油機的幾點改進建議34致謝35參考文獻(xiàn)36附錄37
