a similar dialogue. APPLICATION OF ENGINES A.: No doubt, internal combustion engines have taken a very important part in the technical progress. B.: Yes, you are right! It’s one of the best inventions of the mankind! A.: Having studied the history of transport we have realized, that the invention and development of the internal combustion engines in the nineteenth century had a profound impact on human life. B.: It goes without saying. Moreover, after the commercial drilling and pro- duction of petroleum in the mid-1850s engineering advances led to their widespread adoption in a variety of applications. A.: I do know about it. These engines appeared in transport in almost all ve- hicles: automobiles, trucks, motorcycles, boats, and in a wide variety of aircraft and locomotives. B.: It’s great! And what about the main differences between them? I mean their sizes and mechanical power. I believe the engines must differ from each other. A.: I agree with you on this point. But engines technology is constantly chang- ing and at present some engines manufacturers are producing definite types for different kinds of vehicle. B.: I wonder what ways the internal combustion engines are classified into. A.: You see, modern internal combustion engines can be classified in a num- ber of different ways, depending on their technical characteristics and their usage in different types of vehicles. 226 B.: By the way, the Wankel engine is considered to be one of the most reliable and the simplest one. What do you think about it? A.: I think so, too. It is really simpler and much lighter. It contains far fewer moving parts. For instance, it has no valves or complex valve trains. But most engineers and scientists from different countries of the world discuss its advantages and disadvantages. They also do their best to make it more advanced and effective. B.: It’s going to be interesting to see if the popularity of the Wankel engine continues to increase in the future. A.: To my mind, it will be used in modern models of different kinds of transport. B.: I see. Thanks a lot for your comments. A.: You are welcome. жүктеу/скачать 4,38 Mb. Достарыңызбен бөлісу:
