for facilitating installation; for adding safety to any vehicle; for enhancing the visibility of the driver; for making safer lane changes; for helping the driver and the pedestrians; for reducing accidents successfully; for attracting more attention; for increasing the visibility of the vehicle’s turn signal; for seeing the vehicles hidden from the view

19. Keep smiling.

A . Look After My Car.

“Can you drive?”

“No, I’m sorry, I can’t.”

“That’s good! Will you look after my car for an hour?

B. I’ve Run Over Your Cat!

One day a man ran over Mrs. Brown’s cat in the street. He went to Mrs. Brown and said: “I'm terribly sorry. I’ve run over your cat and I’d like to replace it.”

“It’s all right with me,” said Mrs. Brown. “But can you catch mice?”

C. Misunderstanding

“What sort of car has your family got?”

“I can’t remember its name. I think it starts with “T.”

“Really? Ours starts with petrol.”

20. Skim the text “Fuel Types” and find the best answer to the question: “Why is selecting fuel important?” You can take prompts in the statements below.

There are different types of fuel. Research Octane Number (RON) is a measure of fuel’s compression performance and the RON rating given translates into amount of engine power. RON requirements vary according to engine type.

Unleaded Petrol is the most common fuel type for passenger vehicles. ULP has a RON of between 91 and 93.

Lead Replacement Petrol was introduced as an environmental alternative for cars that used leaded petrol. LRP has a research Octane Number of 96. LRP has been slowly phased out and its availability is limited. LRP was refined to contain no lead along with lower concentrations of benzene and sulphur.

98 RON is a high-octane unleaded fuel that maximizes engine power and performance, as well as producing less pollution. 98 RON is promoted as providing excellent fuel economy, has a sulphur content which is 10 times lower than the national standard for unleaded fuels, and has low levels of benzene, sulphur and lower aromatics. 98 RON is used by some imported and high performance vehicles.

Diesel engines are usually very efficient engines, offering better fuel economy in comparison to equivalent petrol models. Diesel engines emit very low levels of exhaust hydrocarbons and carbon monoxide when correctly tuned and maintained. At the same time, the main concern diesel engines raise is the smoke they emit, which can be a health hazard. Ultra low sulphur diesel is already available.

A new diesel comprising 30 percent biofuel is now being tested and produced in Belarus. It is Grodno filling stations that offer latest bio-fuel to drivers. The new diesel is less toxic and smoky and provides better lubrication than ordinary diesel fuel.

Alternative fuels began appearing some time ago, with scientists all over the world working hard to find substitutes for refined oil products. In Italy, they mash grape-stones to create oil, but rape-seed is the most suitable product for Belarus nowadays.

LPG (most commonly a blend of propane and butane) is an environmentally cleaner fuel compared to petrol and diesel. LPG retail prices tend to be lower than other fuel products.

1. A knocking can occur in an engine when there is a mismatch between the fuel characteristics and the engine’s design, particularly its compression ratio, resulting in preignition.

2. Selecting fuel with the correct RON for your engine will prevent the knocking fuel effect caused when the fuel combusts in the compression chamber too early. RON 110 is becoming popular now.
