摘 要
柴油機(jī)在現(xiàn)代動(dòng)力機(jī)械中起著重要的作用。為了解和研究柴油機(jī)的總體結(jié)構(gòu)及其動(dòng)力性能，本次畢業(yè)設(shè)計(jì)涉及到“4110型柴油機(jī)總體設(shè)計(jì)”。文中詳細(xì)地闡述了柴油機(jī)的機(jī)體組件、活塞連桿機(jī)構(gòu)、配氣機(jī)構(gòu)、燃油系統(tǒng)、潤(rùn)滑系統(tǒng)、冷卻系統(tǒng)、電氣系統(tǒng)等七大系統(tǒng)的設(shè)計(jì)重點(diǎn)。理解柴油機(jī)工作原理、過(guò)程，并參照4110型柴油機(jī)原型及主要參數(shù)進(jìn)行了柴油機(jī)的總體布局設(shè)計(jì)。通過(guò)熱力、動(dòng)力計(jì)算及使用情況的分析，對(duì)4110型柴油機(jī)提出了合理的建議并進(jìn)行改進(jìn)。經(jīng)過(guò)改進(jìn)，柴油機(jī)的動(dòng)力性能和經(jīng)濟(jì)性能得以提升，以適應(yīng)需求。此次畢業(yè)設(shè)計(jì)的選題意義在于提倡使用動(dòng)力性能更好和節(jié)能環(huán)保的柴油機(jī)。

Abstract
Diesel engine plays an important role in modern power machinery. In order to make a further research of diesel engine, this paper is mainly concerned with the system design of 4110 type diesel engine. It is within the significant designing of airframe components、piston and crank mechanism、modified atmosphere mechanism、fuel system、lubricating system、cooling system and electrical system in detail. With the better understanding of diesel engine working principle and process or 4110 type diesel engine primary form and main parameters, the general layout design can be conducted as soon as possible. What is more, through the analysis of heat calculation、power calculation and uers′ feedback, reasonable suggestions for the 4110 type diesel engine are put forward and then improved. As a result, power performance and economic performance are enhanced to meet demand for use. The important significance presented in this paper lies in advocating to use better power performance、energy conservation and environmental protection in diesel engine.
Key Words：4110; diesel engine; system design; improvement; performance
