Ex.3 Compose 5 questions for the text
Who was the first to create a self-driving road car?
What elements did Kulibin use when creating a three-wheeled carriage?
What fuel did the internal combustion engine that Lenoir created use?
How does a diesel engine?
What are the disadvantages of a diesel engine?
Ex.4 Find (write) Conditionals in the text (minimum 2)
This would be a major advantage if severe petroleum shortages develop.
Two prime factors lie behind the search for different engines - the necessity to reduce air pollution by requiring cleaner auto exhaust and the desire to produce cars that will ran farther on a gallon of fuel.
Engineers point out that a Stirling engine would be quieter that an equivalent internal combustion engine, would emit less toxic gases, and would use fuel more economically.
Ex.5 Find Subordinate Clauses ( with which, that, when, as, where - minimum 10)
In 1972, Ford signed an agreement with the firm for joint development of a Stirling engine for passenger cars.
Up to 1790 most all road vehicles were powered by steam engines which ran at slow speeds
In 1860 Lenoir of Paris built an internal combustion engine which ran on city gas, the gas being ignited by an electric spark.
In 1866, Otto invented the type of four-stroke cycle engine which is used today.
While basic research is continuing on electric and steam-powered engines, it is the diesel, turbine and Stirling that are current industry favourites.
All the companies investigating diesels are trying to reduce noise and smoke, but the problems are not yet entirely solved. Even the 28,000-dollar Mercedes clatters when started on a cold morning
However, when Stirling died in 1878 at the age of 88, his engine was still unperfected
In his vehicle he used for the first time such new elements as brakes, rollers and a gear-box.
As air is drawn into the engine and compressed internal temperatures rise, and pressures reach two to three times those in a gasoline engine
As piston moves, it forces gas out of the other end of the cylinder; the emerging gas is cooled and then moves towards an adjacent cylinder where heat is applied once more and the process is repeated.
