TEXT

From the History of Russian Automobile Engineering

The automobile industry in our country has been developed since 1916. Before that time Russia had no automobile industry at all, tech­nical schools had no departments to train specialists in automobile engineering.

But in the history of the automobile such names as Shamshurenkov, Blinov, Mamin and other Russian experts in mechanics must be re­membered.

The first automobile built by Shamshurenkov, a Russian inventor, was put into motion by the pedalling of the driver himself.

Blinov designed and constructed tractor driven by steam engine. Mamin was one of the pioneers in Russian internal combustion en­gines.

Today Russian automobiles are engineered and built in such a manner that they are able to withstand heavy loads for long periods of operation.

The modern automobile is much more than a means of riding from one place to another. The passenger's safety and comfort must be con­sidered as much as the car's reliable performance and ability to travel on the highways.

The modern automobile must have a steel body and a steel roof and this roof must be insulated against the summer's heat and winter's (old. Ventilation is also of great importance. The comfort and conven­ience of the driver must be taken into consideration too. The automo­bile must have a heater with special defrosting devices which insure clear vision to the driver.

The automobile must have great power for riding, have depend­able clutch and brakes, have good riding qualities, good lights, depend­able starting and ignition systems, low fuel consumption, as well as long service life.

TEXT

Benz, Karl (1844 — 1929) was a German inventor of the automobile, who devoted his life to making a horseless vehicle. When Benz's three-wheeled engine-driven machine (the first "car") appeared on I lie streets in 1885, people couldn't believe that it moved without the aid of horses. It was a great triumph to him because Benz built a new engine that was lighter and more powerful than any other. He put it onto a chassis and got power from the engine to the wheels. Benz's first car was a great achievement for him. Everything — the engine, fuel transmission, controls — had been developed and designed by him. The wheels were driven by means of a chain, and there were two speeds.

In his early days the speed limits were 12 kilometers an hour out­side the city, six — inside. Benz realized that he would never be able to improve his cars if this rule were not changed. He thought up a plan. He invited the Minister to ride in his car and agreed with a milkman that the latter would wait with his horse for them on a certain place. When Benz, with the Minister in his car, passed the milkman, the lat­ter started off, passed the car at a good speed and laughed at them. The plan worked perfectly. The Minister ordered to go faster. But Benz re­ferred to speed limit. "Never mind", said the Minister. Thus Benz won the day.

TEXT 1

Internal Combustion Engines

The first internal combustion engine light enough in weight was the gasoline engine, invented by a German named Otto.

At the same time Dr. Rudolph Diesel was working on the diesel engine. The Diesel engine is similar to the gasoline engine in many ways. There are many variations in engine arrangements, but the basic parts of most 4-stroke cycle engines are similar.

 

 

In the in-line arrangement the cylinders are lined up in a single row. The V-type engine is called so as the cylinders form 2 rows or "banks", set at an angle to each other to form the letter V.

The diesel engine gets its power from the expansion of burning gases. The diesel engine depends on the heat of compression for igni­tion of the fuel.

Liquid fuel that contains more heat energy than gasoline is diesel

oil.

Diesel oil is slower burning, but it produces more power. Diesel engines also must be heavier than gasoline engines, but they are more efficient when working under heavy loads at low speeds.

The advantages of the diesel over the gasoline engine are as fol­lows:

a).more economic operation;

b).higher compression ratio;

c).reduced maintenance costs;

d).good pulling power.

TEXT 2

Engines

The two most common types of engines for cars are the petrol engine and diesel engine.

Petrol engines are usually lighter and smaller than diesel engines. This makes them cheaper, and this is why most cars use petrol engines. Petrol engines are also less noisy than diesel engines. They usually go foster. On the other hand, diesel engines use less fuel than petrol en­gines, and this is why trucks use them. They are also safer than petrol engines, because there is less danger of fire.

There are two main types of petrol engine - 4-stroke and 2-stroke. All cars use 4-stroke engines. But most motorbikes use 2-stroke engines. They are lighter and smaller than 4-stroke engines, and are there­fore cheaper.

The "UAS" Model

This model designed as "go anywhere" vehicle is built by the Ulyanovsk Plant. It gives high performance under all conditions. All the four wheels of this model are driving ones. Roadless is easily over­come at medium speeds. Stable suspension gives great riding comfort even under off-road conditions.

To protect passengers and the driver from sun rays, winds and rains the UAS is equipped with a weather proof hood. In cold weather an effective heater system may be switched on.

This model possesses excellent road stability and is easy in con­trol. Well-balanced, synchromesh gearbox, effective brakes provide additional conveniences for the driver. Maintenance of the car is ex­tremely simple, as all points, which are frequently lubricated and ad­justed are easily accessible. The body is an all-metal, two-door, eight - seater construction. The clutch is of a single dry plate type.

The transmission has three forward and one reverse speeds. The lower gear can be put in only when the front axle is engaged.

1. At what plant is the model built?

2. Does it give high performance under all conditions?

3. At what speeds is roadless overcome?

4. What is done to protect passengers from wind and rain?

5. What may be switched on in cold weather?

6. Why is maintenance of the car extremely simple?

7. How many speeds has the transmission?
