【正文】 engine with no catalytic converter, PM emission of diesel fuel with sulfur content approx. 273106 is reduced by % as pared with diesel fuel with sulfur content approx. 800106。 to meet Euro III emission standard, the key in the development of electronicallycontrolled diesel engine with no tail gas aftertreatment device is to develop diesel engine bustion system and control lubrication oil consumption.Key words: Sulfur content。 Diesel engine。 PM emission電控噴射單一燃料CNG轎車發(fā)動(dòng)機(jī)的性能試驗(yàn)張群1，2 王天友1 吳喜慶1，2 郭云杰1 王剛德1 付曉光1李 琦2 劉書亮1（；）【摘要】研究了過量空氣系數(shù)及點(diǎn)火時(shí)刻對(duì)某電控噴射單一燃料壓縮天然氣發(fā)動(dòng)機(jī)的動(dòng)力性、經(jīng)濟(jì)性和排放性能的影響。試驗(yàn)結(jié)果表明，在整個(gè)轉(zhuǎn)速范圍內(nèi)，%，%。在此基礎(chǔ)上得到了在變過量空氣系數(shù)和點(diǎn)火時(shí)刻下，該天然氣發(fā)動(dòng)機(jī)的燃燒、排放規(guī)律。主題詞：壓縮天然氣發(fā)動(dòng)機(jī) 過量空氣系數(shù) 點(diǎn)火時(shí)刻 性能試驗(yàn)Performance Test of CNG Car Engine featuring Electronicallycontrolled InjectionZhang Qun1,2, Wang Tianyou1, Wu Xiqing1,2, Guo Yunjie1, Wang Gangde1, Fu Xiaoguang1, Li Qi2, Liu Shuliang1(1. State Key Laboratory of Internal Combustion Engines, Tianjin University。 2. Tianjin FAW Xiali Automobile Co., Ltd)【Abstract】The effect of excessive air coefficient and ignition timing on dynamic performance, fuel economy and emission performance of an electronically controlled injection dedicated CNG car engine was studied. The test results show that the engine’s BSFC is about % lower and effective thermal efficiency is % higher as pared to gasoline engine. Based on this, the law of bustion and emission of CNG engine is obtained under variable excessive air coefficient and ignition timing.Key words: CNG engine。 Excessive air coefficient。 Ignition timing。 Performance test基于UG的車身點(diǎn)云數(shù)據(jù)快速對(duì)齊方法高尚鵬 徐家川 李迪 （山東理工大學(xué)）【摘要】根據(jù)圖形坐標(biāo)變化理論，提出了基于UG點(diǎn)擬合法的汽車車身點(diǎn)云數(shù)據(jù)坐標(biāo)快速對(duì)齊方法，介紹了點(diǎn)擬合法的坐標(biāo)變化理論及汽車車身坐標(biāo)系與UG系統(tǒng)坐標(biāo)系的對(duì)齊方法。結(jié)合工程實(shí)例，利用點(diǎn)擬合法快速準(zhǔn)確地實(shí)現(xiàn)了車身點(diǎn)云數(shù)據(jù)的坐標(biāo)對(duì)齊，驗(yàn)證了該方法的有效性。主題詞：車身 點(diǎn)云數(shù)據(jù) 擬合方法The Rapid Alignment Method of Point Cloud Data for Auto Body based on UGGao Shangpeng, Xu Jiachuan, Li Di (Shandong University of Technology)【Abstract】In accordance with graphic coordinate change theory, the rapid alignment method of point cloud data for autobody based on the UGpoints fit method is presented in the paper, in which the coordinate change theory of point fit method and the alignment method of autobody coordinate and UG system coordinate system are introduced. It takes engineering example to use the point fit method to align the coordinate of autobody point cloud data quickly and correctly. The result verified effectiveness of this method.Key words: Autobody。 point cloud data。 fit method基于數(shù)字化工廠的白車身焊裝前期規(guī)劃寧宇1,2 韓英淳1 李悅2（；）【摘要】以某企業(yè)B車型主焊線規(guī)劃為例，對(duì)數(shù)字化工廠技術(shù)在其白車身焊裝線前期規(guī)劃中的應(yīng)用進(jìn)行了闡述。介紹了基于數(shù)字化工廠的白車身焊裝解決方案及前期規(guī)劃的內(nèi)容、流程和實(shí)施方法。由于在前期規(guī)劃中進(jìn)行了焊點(diǎn)可達(dá)性分析、機(jī)器人仿真分析和干涉檢查等，因而大大縮短了各工位夾具與抓具的設(shè)計(jì)時(shí)間并提高了準(zhǔn)確率，顯著減少了后期修改工作量。主題詞：白車身 數(shù)字化工廠 焊裝線 前期規(guī)劃Advanced Planning of BIW Welding based on Digital FactoryNing Yu1,2, Han Yingchun1, Li Yue2(1. Jilin University。 2. FAW Mould Manufacturing Co., Ltd)【Abstract】With the welding line planning of vehicle model B of a pany as example, the paper elaborates the application of digital factory technology in BIW welding line advanced planning. The paper introduces BIW welding solution based on digital factory as well as content, flow and implementation of advanced planning. Since welding spot reachability analysis, robot simulation analysis and interference check, etc., are conducted in the advanced planning, therefore the design time of jig and gripper are shortened, accuracy rate is improved, modification work in the later stage is considerably reduced.Key words: BIW。 Digital factory。 Welding line。 Advanced planning17 / 17
