A diesel engine is a machine that converts chemical energy into mechanical energy by the method of high-pressure internal combustion. Mechanical energy enables the movement of pistons in a cylinder in the diesel engine, which in turn facilitate the movement of a crankshaft. A diesel engine is composed of several components such as fuel injector, piston, connecting rod, crankshaft, and combustion chamber. Unlike petrol engine, diesel engine does not have a spark plug for igniting the fuel. Diesel engines are used in several industries such as Automotive, Aerospace, Shipbuilding, Machinery, and Locomotive. In addition, these are increasingly used for power backup. Diesel generators are also deployed across residential, commercial, and industrial buildings for uninterrupted power supply. Diesel generators are incorporated with agenhead that produces electrical output from mechanical energy developed in the engine and works under the principle of electromagnetic induction, generating electric current from diesel engines.

作为广本的重点车型，凌派有望成为盈利的重要增量。长城汽车产能规划解除未来3年发展后顾之忧，我们持续看好公司的成长性。安全管理是动力电池的发展瓶颈之一，理论上可控可知，但实际应用中隐患较难消除。凌派领衔，本周共有5款新车上市。本周乘用车表现相对优异，零部件和商用货车指数下挫幅度较大。

2013 年1-5 月汽车销售同比增长12.6%。2013 年1-5 月，国内汽车销售902.81 万辆，同比增长12.6%。其中乘用车销售726.16 万辆，同比增长14.7%；商用车销售176.65 万辆，同比增长4.5%。1-5 月，汽车出口40.23 万辆，同比仅增长5.3%。1-4 月，17 家汽车行业重点企业(集团)累计实现营业收入同比增长10.1%，利润总额、利税总额保持稳步增长。9 月份后，伴随日系车的较高增长，我们对2013 年全年汽车销售同比增长13%充满信心。
