Nitrous oxide (added / is added) oxygen molecules into the fuel. c. A team of designers (has developed / has been developed) a new transmission system. d. In an engine, energy stored in its fuel (transforms / is transformed) into useful work power. e. The engine (exhausted / was exhausted) the remaining heat energy as mechanical sound or friction loss.

3. Перепишите и переведите предложения, обращая внимание на употребление модальных глаголов. Подчеркните модальные глаголы в английских предложениях и в переводе. a. Direct injection diesel engines can offer about 40 percent efficiency. b. Constructors had to solve the problem of exhausted heat and friction loss. c. The engine worked better when it was able to engulf more oxygen. d. The chemical fuel energy must be transformed into useful work power.

4. Образуйте от данных глаголов две формы Participle I. Полученные причастия переведите на русский язык. Model: to install –a) installing – устанавливающий, устанавливая b) having installed – установив to write – a) writing – пишущий, при написании b) having written – написав a) store; b) break; c) feed; d) transform; e) expel; f) create; g) drive; h) ignite; i) leave; j) move

5. Перепишите и переведите предложения, обращая внимание на употребление Participle I в функциях определения и обстоятельства. Подчеркните причастия I в английских предложениях и в переводе. a. Modern gasoline combustion engines operating at 20 to 30 percent engine efficiency, needs some improvement. b. The remaining gasoline's heat energy is ejected from the engine as exhaust heat, mechanical sound energy or friction loss. 27 c. At idle, the engine does not move the vehicle, only operating accessories, like the water pump and generator. d. The diesel engine using high compression to ignite its fuel is a bit more efficient.

6. Образуйте от глаголов данных в скобках, Participle II.

(engulf) oxygen; g. fuel (burn) in combustion chamber; h. (ignite) fuel mix

7. Перепишите и переведите предложения, обращая внимание на употребление Participle II в функциях определения и обстоятельства. Подчеркните причастия II в английских предложениях и в переводе a. Engines transform the energy stored in their fuel into useful work power. b. The amount of oxygen engulfed by the engine was crucial. c. If seriously broken, this engine is absolutely impossible to be restored. d. Burning of the added fuel allows the engine to operate more efficiently.

8. Перепишите и письменно переведите текст: ENGINE’S EFFICIENCY FACTORS Engine efficiency is an engine's ability to transform the energy stored in its fuel into useful work power. The modern gasoline combustion engine on average operates at about 20 to 30 percent engine efficiency. The remaining 70 to 80 percent of the gasoline's heat energy is expelled from the engine as exhaust heat, mechanical sound energy or friction loss*. At idle, the engine efficiency is zero because the engine is not moving the vehicle, only operating accessories, like the water pump and generator...........

9. Определите, являются ли следующие высказывания верными (right) или неверными (wrong). Исправьте неверные предложения в соответствии с текстом. a. The engine's efficiency rating doesn’t depend on fuel type. b. The more oxygen is engulfed, the worse the efficiency is. c. High compression ignition enables an engine to work better. d. More than fifty percent of energy in gasoline combustion engines makes no useful work. e. Gasoline with a lower octane level creates bigger engine efficiency.
