Пояснения к тексту:

The early days of the automobile

1. One of the earliest attempts to propel1 a vehicle by mechanical power was

suggested by Isaac Newton. But the first self-propelled vehicle was constructed by the French military engineer Cugnot in 1763. He built a steam-driven engine which had three wheels, carried two passengers and ran at maximum speed of four miles. The carriage was a great achievement but it was far from perfect and extremely inefficient.

The supply of steam lasted only 15 minutes and the carriage had to stop 100 yards to make more steam.

2. From 1800 to 1900 was a period of the application of gasoline engines to motor cars in many countries. The first to perfect gasoline engine was N. Otto who introduced the four-stroke cycle of operation. The cars of that time were very small, two-seated cars with no roof, driven by an engine placed under the seat. Motorists had to carry largecans of fuel and separate spare tyres, for there were no repair or filling stations to serve them.

3. After World War I it became possible to achieve greater reliability of motor cars ,brakes became more efficient. Multi-cylinder engines came into use, most commonlyused are four-cylinder engines.

4. Like most other great human achievements, the motor car is not the product of any single inventor. Gradually the development of vehicles driven by internal combustion engine-cars, as they had come to be known, caused huge capital flow into the automobile industry. From 1908 to 1924 the number of cars in the world rise from 200thousand to 20 million; by 1960it had reached 60 million! No other industry had everdeveloped at such a rate.
