Many people have known now, the turbocharging is called TURBO, if saw in the passenger vehicle rear part TURBO or T, namely indicated this vehicle uses the engine is the turbocharging engine. These automobiles engine work, is makes the merit depending on the fuel in the engine cylinder internal combustion, thus foreign output. In engine capacity certain situation, if wants to raise engines output, the most effective method provides the fuel burning much. However, provides the fuel to the air cylinder in easily to do, but must provide the enough quantity the air to support the fuel to burn completely, is very difficult to complete depending on the traditional engine air intake system. Key words: Turbo; Air cylinder internal combustion; Fuel 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc256000000 姹钱泪浠侄吐啪昴藿知毁摇梧膜 PAGEREF _Toc256000000 \h 4 HYPERLINK \l _Toc256000001 1 废气涡轮增压概述惬菸漭髹呕绫羔俯潭仍螳伴砩概 PAGEREF _Toc256000001 \h 1 HYPERLINK \l _Toc256000002 1.1 废气涡轮增压器的背景鸲洚苇顶果筒房汩魈藏岗纭石胞 PAGEREF _Toc256000002 \h 1 HYPERLINK \l _Toc256000003 1.2 废气涡轮增压器产业的技术发展阗讹齑砬淋锼翰磙模弧避硬侩嘲 PAGEREF _Toc256000003 \h 2 HYPERLINK \l _Toc256000004 1.3 废气涡轮增压器原理简倦戗饽鲛镜垮冕衢芩赤遏痦孪 PAGEREF _Toc256000004 \h 3 HYPERLINK \l _Toc256000005 2 废气涡轮增压器压气机结构设计此升恶挠桃胭爨奠樘限背夤镊摩 PAGEREF _T
