The main part of the engine is called the block. It consists of the cylinders and the valves. Air and petrol go into the block by means of the carburettor. The petrol reaches the carburettor from the petrol tank through the action of the petrol pump.
There are two main types of petrol engines: 4-stroke and 2-stroke. All cars and larger motor-cycles are known to use 4-stroke engines. But most smaller motorbikes use 2-stroke engines. They are smaller and cheaper than 4-stroke engines.

3. Lomonosov established the fundamental law of chemical change of substance which is called the Law of Conservation of Mass.
4. Lomonosov founded a new science that we call today physical chemistry. He also studied electrical phenomena in atmosphere of the Earth, the nature of light, and designed an improved telescope. Lomonosov considered nature to be in a state of constant change and development. Coal, oil, etc. were all formed as a result of evolution.
5. Lomonosov was a great scientist. His works in poetry had a great influence on Russian literature. Owing to his efforts, the first Russian University was founded in Moscow in 1755. This university bearing his name became the centre of knowledge and science in Russia.
