The cylinder head is located at the top of the engine block.

THE advent of higher engine operating speeds and output, has made it increasingly difficult to assess the strength of crankshafts of modern internal combustion engines by analytical methods. Binding, J. Report bugs here. Please share your general feedback.

Petrol engine British English or gasoline engine American English is an internal combustion engine with spark-ignition , designed to run on petrol gasoline and similar volatile fuels. In most petrol engines, the fuel and air are usually pre-mixed before compression although some modern petrol engines now use cylinder- direct petrol injection. The process differs from a diesel engine in the method of mixing the fuel and air, and in using spark plugs to initiate the combustion process. In a diesel engine, only air is compressed and therefore heated , and the fuel is injected into very hot air at the end of the compression stroke , and self-ignites. With both air and fuel in a closed cylinder, compressing the mixture too much poses the danger of auto-ignition — or behaving like a compression-ignition engine. Because of the difference in burn rates between the two different fuels, petrol engines are mechanically designed with different timing than diesels, so to auto-ignite a petrol engine causes the expansion of gas inside the cylinder to reach its greatest point before the cylinder has reached the top dead center TDC position.

Main Components of Cylinder Heads & Their Function

Cylinder liners are the interior metal components within the piston that protect it from the wear and tear of the operation of the motor. Three basic types of liners are used: hot, dry and finned. The purpose of each type is to protect the piston from heat and impurities using slightly different methods. Cylinder liners are expensive, precisely manufactured products and are primarily purchased from specialty shops. Dry cylinder liners are among the basic piston protectors.

A crankshaft is a shaft driven by a crank mechanism, consisting of a series of cranks and crankpins to which the connecting rods of an engine are attached. In a reciprocating engine , it translates reciprocating motion of the piston into rotational motion, whereas in a reciprocating compressor , it converts the rotational motion into reciprocating motion. In order to do the conversion between two motions, the crankshaft has "crank throws" or "crankpins" [ clarification needed ] , additional bearing surfaces whose axis is offset from that of the crank, to which the "big ends" of the connecting rods from each cylinder attach. It is typically connected to a flywheel to reduce the pulsation characteristic of the four-stroke cycle , and sometimes a torsional or vibrational damper at the opposite end, to reduce the torsional vibrations often caused along the length of the crankshaft by the cylinders farthest from the output end acting on the torsional elasticity of the metal. They were used for silk-reeling, hemp-spinning, for the agricultural winnowing fan, in the water-powered flour-sifter, for hydraulic-powered metallurgic bellows , and in the well windlass. A crank in the form of an eccentrically-mounted handle of the rotary handmill appeared in 5th century BC Celtiberian Spain and ultimately spread across the Roman Empire. Evidence for the crank combined with a connecting rod appears in the Hierapolis mill , dating to the 3rd century; they are also found in stone sawmills in Roman Syria and Ephesus dating to the 6th century.

V-8 engines are one of the most common styles of engine across the entire automotive industry, especially when the goal is to produce a lot of power with a smooth delivery. So, how does such an engine work? Jason Fenske of Engineering Explained is here to shed light on how a V-8 engine operates. Specifically, he uses a General Motors' popular LS3 6. Foremost, the V-8 operates like any other gasoline-powered four-stroke engine. The cylinder pulls in air and fuel, compresses the air and fuel, a spark plug ignites the mixture to create power and forces the piston downward, and finally, the piston pushes exhaust gases out as it travels back up.

After the war, and as a result of the economic and financial crisis which brought almost complete stagnation to the automotive industry in Germany during the early twenties, these two companies were practically forced to combine their activities in order to survive. Accordingly in a merger was consummated between the Daimler and Benz organizations. Young, R. Report bugs here. Please share your general feedback.

Еще несколько мгновений, и весь набор фильтров был восстановлен. Банк данных снова был в безопасности. В комнате творилось нечто невообразимое. Техники обнимали друг друга, подбрасывая вверх длинные полосы распечаток. Бринкерхофф обнимал Мидж.

Мидж покачала головой: - Настолько сложной, что она длится уже восемнадцать часов? - Она выдержала паузу.  - Маловероятно. Помимо всего прочего, в списке очередности указано, что это посторонний файл. Надо звонить Стратмору. - Домой? - ужаснулся Бринкерхофф.  - Вечером в субботу.

 Если Дэвид не добьется успеха, а ключ Танкадо попадет в чьи-то руки… Коммандеру не нужно было договаривать. Сьюзан и так его поняла. Пока файл Цифровой крепости не подменен модифицированной версией, копия ключа, находившаяся у Танкадо, продолжает представлять собой огромную опасность. - Когда мы внесем эту поправку, - добавил Стратмор, - мне будет все равно, сколько ключей гуляет по свету: чем их больше, тем забавнее.  - Он жестом попросил ее возобновить поиск.

Я любил тебя. Сьюзан. Сьюзан. Сьюзан… Она знала, что его уже нет в живых, но его голос по-прежнему преследовал. Она снова и снова слышала свое имя.

Стратмор приближался к ней, его лицо казалось далеким воспоминанием. Холодные серые глаза смотрели безжизненно. Живший в ее сознании герой умер, превратился в убийцу. Его руки внезапно снова потянулись к ней в отчаянном порыве. Он целовал ее щеки. - Прости меня, - умолял .

 - Ты только посмотри. Сквозь строй дважды отверг этот файл.

Мидж смотрела на цифры, не веря своим глазам. - Этот файл, тот, что загрузили вчера вечером… - Ну. - Шифр еще не вскрыт.

 Сьюзан, - сказал он торжественно.  - Здесь мы в безопасности. Нам нужно поговорить. Если Грег Хейл ворвется… - Он не закончил фразу. Сьюзан потеряла дар речи.

Глаза немца расширились. - Was tust du. Что вы делаете.

Или это его подвинули. Голос все звал его, а он безучастно смотрел на светящуюся картинку. Он видел ее на крошечном экране.
