Writing

I. Write a paragraph about the fuel system operation. The words below will help you.

a fuel tank, a fuel pipe, a fuel pump, a carburettor, a piston; to mix, to burn, to compress, to consist of, to produce

II. Translate the text into Ukrainian.

A driver's response time is very slow in comparison to that of elec­tronic systems. A quick human response is around 0.5 seconds, and some responses are as slow as 1 to 2 seconds. Let's consider a driver who is travelling at 40 mph and has a response time of 1 second. A simple calculation (distance = speed x time) shows that the car will travel 17.9 m before the vehicle motion is changed. In comparison, electronic systems operate at a tenth of a second and have the poten­tial to operate in milliseconds. In severe maneuvers, the car stability is increased by this quicker response and people's life is saved.

I. Cars play a very important role in the modern world. In our everyday life we use cars probably more than any other means of land transport But it's not very safe to drive a car today. What would you like to improve in a car? Discuss this problem with your partner.

II. Analyse the following compound nouns and translate them into Ukrainian.

the automatic vehicle control

the steering wheel

the microprocessor controller

the steering device

the sensor information

the wheel motion system

the drive subsystem

III. Nowadays car technology is constantly improving. Read the text about such improvements and be ready to answer the questions that follow.

The basic elements that control vehicle motion have changed lit­tle in their concept over the past few decades. Vehicles are still driven by an internal combustion engine, steering is achieved by driving a mechanical gear and brakes are actuated by physically pumping hydraulic pistons. All these actions are carried out by the driver.

The status quo is ready for change. Under development are fast-reacting, intelligent systems that increase the possibility of auto­matic vehicle control.

In such vehicles the steering, accelerator and brake devices are connected to a sensor that monitors their position. The sensor passes this information as an electrical signal to the microprocessor con­troller.

The sensor information is processed and the actions for the steering, brakes and drive subsys­tems are calculated.

The picture shows the outline of an automotive chassis. This differs from a conventional chassis as motion of each wheel is achieved by independent suspension, drive, brake and steering. The main control unit receives electrical signals from the steering wheel and pedals, and produces electrical signals that actuate the wheel motion systems.

In this design there is a possibility to modify the steering, brake and accelerator device. All these could be integrated into a single joy­stick. This possibility is a major advantage when we want to modify cars for the physically challenged (який страждає фізичними вадами).

1. Have the basic elements that control vehicle motion changed a lot over the past few decades?

2. What are vehicles driven by?

3. Who carries out all these actions?

4. What is under development now?

5. Do you think it's a good idea to develop automatic vehicle control?

IV. Arrange the operation stages of a typical automatic vehicle control.

a) The sensor information is processed by this controller.

b) A special sensor in the car monitors the position of the steering, accelerator and brake input devices.

c) The actions for the steering, brakes and drive subsystems are calculated.

d) This information is passed by the sensor as an electrical signal to the microprocessor controller.

V. Retell the text.
