Exercises
1. Answer the questions.
1. What is a good signal of abnormal operation?
2. Why is it necessary to replace worn parts?
3. In what case is it necessary to set new pistons?
4. What do you do if you have piston wear?
5. Which mechanism faults cause compression reduction?
6. Is it necessary to repair the engine if you have the wear of rings, bushes or cylinder walls?
7. How do you wash the cylinder?
8. When is the cylinder head fitting not tight?
9. What do you do to replace the gasket?
10. What faults can be detected in the gas-distributive mechanism?
2. Express your agreement or disagreement with the following statements.
1. Clatters in the crank mechanism are a good signal of abnormal operation.
2. Clatters in the crank mechanism can be the result of a cooling system fault.
3. Worn piston rings can be replaced with new ones.
4. The clatters are the result of reduction of the cylinder diameter.
5. Faults in the crank mechanism cause pressure reduction.
6. If we have wear of the rings, cylinder walls or bushes - the engine should be repaired.
7. If the cylinders have scratches on the operating surface, replace these cylinders.
8. If you have a damaged gasket, tighten it.
9. Faults in the gas-distributive mechanism cause compression reduction.
10. The valve mechanism does not operate when the valves are closed.
3. Name the parts, need to be repaired or replaced in case of pressure reduction.
1. Wearing of the rings...
2. Scratches on...
3. The piston rings sticking...
4. The unit head fitting...
4. Name the verbs describing operations for gasket replacement.
5. Guess, what is wrong?
1. It deals with the valves and it causes compression reduction and sometimes engine power reduction.
2. Wear in the gears, bearings and camshaft neck causes clatters during engine operation.
6. Read the dialogue.
At the Service Station
Customer - Excuse me, Sir.
Attendant - Yes, Sir?
Customer - Something is wrong with my car.
Attendant - What's wrong?
Customer - The car has broken down, but you see, I'm just a beginner. I can't find the problem.
Attendant - Let me have a look at it.
Customer - Here it is. Each time I start the engine I hear a strange noise.
Attendant - What noise do you hear?
Customer - I suppose, a metal one and rather loud.
Attendant - Let me listen to it. Aha, you have a compression reduction in the engine; the gases and fuel steam penetrate into the crankcase mechanism. And the plugs are contaminated.
Customer - Can you fix it?
Attendant - Of course, I'll check the rings, the cylinder walls and the bushes. And if it is necessary, I'll change the gasket.
Customer - Are you going to dismount the crank mechanism?
Attendant - Sure! You can get your car tomorrow.
7. Answer the questions.
1. What is the matter with the car?
2. Why can't the Customer find the problem?
3. What does he hear when he starts the engine?
4. What kind of noise is it?
5. What has the Attendant found?
6. What is wrong with the car?
8. Reproduce the dialogue.
9. Compose your own dialogue on the situation:
1. Two neighbors are in the garage. One of them (Tom) is a beginner; the other one (Jack) is an experienced mechanic. Tom doesn't know what to do. He is in a mess. The pressure gauge indicates the compression reduction. Jack gives him some pieces of advice.
Words and phrases to be used:
Pressure gauge, to indicate, something has gone wrong to, pressure reduction, a lot depends on the gas-distributive mechanism, valves do not open completely, valves are not closed tightly, snuff on the operating surfaces, the wear of the guide bush, valve sag, a fan-driver, to consult a specialist.
2. A talk between an Instructor (George) and an Amateur Driver (Nick). The Instructor gives some pieces of advice to a beginner: how to detect and correct a fault in a crank mechanism.
Words and phrases to be used:
Abnormal operation, clatter, wear of the shafts, bushes, inserts, increase of the cylinder diameters, to replace, to change, head fitting is not tight, to control the compression.
10. Read and translate the texts in written form.
