CRANK GEAR
The crank gear takes the pressure of gases during the power stroke (combustion and expansion) and converts the rectilinear reciprocating mo-tion of the piston into the rotary motion of the crankshaft. The crank gear consists of a cylinder block with a crankcase, a cylinder head, pistons with rings, piston pins, connecting rods, a crankshaft, a flywheel, and an oil sump.
The cylinder block is the backbone of the engine to which all its mechanisms and parts are secured.
The piston takes up the pressure of gases during the power stroke and transmits it via the piston pin and connecting rod to the crankshaft. The upper part of the piston, called a crown, has grooves which receive the pis-ton rings. The bottom part, called a skirt, guides the piston in the cylinder. The piston skirt has bosses with holes for the piston pin.
The connecting rod serves to connect the piston to the crankshaft. The force applied to the piston during the power stroke is transmitted by the connecting rod to the crankshaft.
The crankshaft takes the forces transmitted from the pistons via the connecting rods and converts them into torque, which is then imparted via the flywheel to the drive line of the vehicle.

Essay on My tripTravelling is the most exciting thing in the world. First of all, it lets us discover the world and to see different countries, experience their cultures and traditions. Moreover, we enrich our knowledge about life in general and particularly about ourselves. Travelling also gives us an opportunity to meet new interesting people, learn new languages and develop our skills. That’s why I’m trying to travel as much as possible.The best trip I’ve ever had in my life was to France. Although it happened two years ago, but I still recall this wonderful time with a great pleasure. I went there with two of my friends and it was really the right decision, because we travelled by coach and the journey took a long time. We were playing cards on the way, singing songs and joking all the time. As we arrived we checked in a hotel not far from the center. We were exhausted but in a good mood.The first day in Paris was fantastic. It was a bus tour around the city called Open Tour. We got on a bus at the nearest stop. It was amazing that it stopped in front of all sights, so we could get off and walk around the most famous places. We took thousands of photos of Eiffel Tower, the Louvre, Arch of Triumph and other monuments. We were impressed by the number of tourists and the beauty of the places we visited. We spent 4 other days in Paris, but this first time our impressions were thrilling.The next days we visited plenty of museums and had some time for small shopping to buy souvenirs. Last evening we went on a small excursion by boat. It was amazing to be on board and to see all the sights again as if they were saying goodbye to us.Thus, it was fantastic time and I hope to come back to Paris one day to get the same marvelous emotions there.Сочинение на тему Мое путешествиеПутешествия — это самая захватывающая вещь в мире. Прежде всего, они позволяют нам познавать мир, а также увидеть различные страны, исследовать их культуру и традиции. Более того, мы обогащаем знания о жизни в целом, а также о нас самих в частности. Путешествия также дают нам возможность познакомиться с новыми интересными людьми, учить новые языки и развивать наши Поэтому я стараюсь путешествовать как можно чаще.Лучшее путешествие в моей жизни было во Францию. И хотя это было два года назад, я все еще вспоминаю это чудесное время с огромным удовольствием. Я ездила с двумя друзьями и это было действительно правильное решение, так как мы путешествовали на автобусе и поездка заняла много времени. В пути мы играли в карты, пели песни и все время шутили. По приезду мы зарегистрировались в отеле неподалеку от центра. Мы были изнурены, но в хорошем расположении духа.Первый день в Париже был отличный. Это был автобусный тур под название Open Tour. Мы сели в автобус на ближайшей остановке. Было чудесно, что автобус останавливался у всех достопримечательностей, поэтому мы могли выйти и прогуляться по самым известным местам. Мы сделали тысячи фотографий Эйфелевой башни, Лувра, Триумфальной арки и других памятников. Мы были впечатлены количеством туристов и красотой мест, которые мы посетили. Мы провели еще 4 дня в Париже, но в этот первый день, наши впечатления были просто захватывающими.В следующие дни мы посетили много музеев, и у нас было немного времени на походы по магазинам, чтобы купить сувениры. В последний вечер мы отправились на небольшую экскурсию на корабле. Находится на борту, и увидеть все достопримечательности снова было так чудесно, как будто они прощались с нами.Итак, мы отлично провели время, и я надеюсь однажды снова вернуться в Париж, чтобы получить те же восхитительные эмоции.

I'm crazy about ball games, and my favorite is football, the most popular sport in the world. This is a very addictive, filled with enthusiasm, game. It was born in England, although the ancient Egyptians and the Mayans played something similar. Football is a hobby of millions of people, and world competitions attract the attention of the whole planet. Professional football became a role model for many children and adults, such as Diego Maradona, Paolo Maldini, Ronaldo, Zinedine Zidane, Andrey Arshavin, Andriy Shevchenko. Football makes players hardy, accurate, fast and smart. The season lasts from early spring to late autumn, so the players are very strong and healthy people, as a lot of training in the fresh air. Football develops a sense of elbow and organization, because it is a team game. And most of all I am attracted to the incomparable football excitement!
