When deciding on the ideal motorcycle to purchase or use, one of the questions to ask yourself is: what kind of engine do I want? What are the differences between a two-stroke engine and a four-stroke engine, and which is better?

Linda Benedict.

A two-stroke or two-cycle engine is a type of internal combustion engine that completes a power cycle with two strokes up and down movements of the piston during only one crankshaft revolution. This is in contrast to a " four-stroke engine ", which requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust or scavenging functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio , power being available in a narrow range of rotational speeds called the " power band ".

When deciding on the ideal motorcycle to purchase or use, one of the questions to ask yourself is: what kind of engine do I want? What are the differences between a two-stroke engine and a four-stroke engine, and which is better? To simplify things, typically motorcycles with two-stroke engines are no longer produced, as they do not comply with the environmental laws of many countries and are not allowed to be driven in cities, and the debate between the two kinds of engines is more applicable to off-road vehicles, such as dirt bikes.

A four-stroke engine, as the name suggests, has a piston that goes through four strokes or two crankshaft revolutions to complete one full cycle; the intake, compression, power and exhaust stroke. This means that when the piston moves down from the top of the cylinder to the bottom, it reduces the pressure inside the cylinder.

This reduced pressure draws a mixture of fuel and air into the cylinder through the intake port. Next, the piston goes back up, compressing the fuel and air mixture, after which a spark ignites the fuel and air. Finally, the piston goes back up and pushes out the combustion gases. After this a new compression stroke follows. Essentially one complete cycle in a two-stroke engine demands one full crankshaft revolution or two piston strokes, whereas in a four-stroke engine the piston has to complete four strokes or two full crankshaft revolutions.

So which is better? Two-stroke engines are typically noisier and produce more exhaust fumes, but also produce more power compared to their weight than four-stroke engines, making them popular for racing. Four-stroke engines, whilst heavier and producing less power per weight unit, are typically described to run smoother, emit less exhaust fumes and generally last longer.

Because the two require completely different lubrication regimes, where in a two-stroke engine the oil is mixed with the fuel and then ignites complete loss of lubrication , whereas in a four-stroke engine the oil used to lubricate the different engine parts flows back in the crankcase and is not consumed. This means that the two engine oils have a completely different composition depending on their intended purpose.

A two-stroke engine oil must be able to mix well with fuel and burn well in the combustion chamber of the engine, whereas a four-stroke engine oil needs to protect the valve train against wear and keep the engine as clean as possible.

Ultimately, no matter which type of engine you have, a high-quality engine oil can significantly extend the lifespan of your engine. Pay attention!

Hey, how are you? Assuming you are good! As we all know the there are two types of engines although there are various kinds of engines are available however these are some popular engines we are talking about one is four-stroke another one is two-stroke. We call an engine 2-stroke when the four successive strokes, i. Suction, Compression, Power, and Exhaust are completed in 1 revolution of the crankshaft, which means in the degree rotation of a crankshaft all the successive strokes are completed. And again we call an engine 4-stroke when the same successive strokes Suction, Compression, Power, and Exhaust are completed in the 2-revolution of the crankshaft.

Automotive engines have transformed over the years, but two main gasoline powered combustion engine designs remain: the 2-stroke and the 4-stroke. How do they work, and which is better? Read on to learn the answers! In order to understand how these two engines are different, you first need to become familiar with the basics. The Difference between a 2-stroke and a 4-stroke engine is how quickly this combustion cycle process occurs, based on the number of times the piston moves up and down during each cycle.

Introduction to Internal Combustion Engines pp Cite as. The absence of the separate induction and exhaust strokes in the two-stroke engine is the fundamental difference from four-stroke engines. In two-stroke engines, the gas exchange or scavenging process can have the induction and exhaust processes occurring simultaneously. Consequently, the gas exchange processes in two-stroke engines are much more complex than in four-stroke engines, and the gas exchange process is probably the most important factor controlling the efficiency and performance of two-stroke engines.

Беккер почувствовал тошноту. Это какая-то глупая шутка. Он не находил слов. - Ты знаешь ее фамилию.

Но мы с мисс Флетчер проводим диагностику особого рода. Это файл высочайшей сложности. Я должен был тебя предупредить, но не знал, что сегодня твое дежурство.

 Увы, - сказал Нуматака, которому уже наскучило играть, - мы оба знаем, что Танкадо этого так не оставит. Подумайте о юридических последствиях. Звонивший выдержал зловещую паузу. - А что, если мистер Танкадо перестанет быть фактором, который следует принимать во внимание.

Похоже, в них угадывался страх. Или это ненависть. Они буквально пожирали ее тело. Новая волна паники охватила Сьюзан.

 Джабба, дело очень серьезное. У меня чутье. У нее чутье. Ну вот, на Мидж снова что-то нашло. - Если Стратмор не забил тревогу, то зачем тревожиться .

Даже его безукоризненный лотос беспомощен перед эскадрильей вертолетов Агентства национальной безопасности. Сьюзан - это единственное, что не позволит Стратмору меня уничтожить. - Сьюзан, - сказал он, волоча ее к лестнице, - уходи со .

Однако выстрелов не последовало. Мотоцикл каким-то чудом перевалил через гребень склона, и перед Беккером предстал центр города. Городские огни сияли, как звезды в ночном небе.

ГЛАВА 4 Потайная дверь издала сигнал, выведя Сьюзан из состояния печальной задумчивости. Дверь повернулась до положения полного открытия. Через пять секунд она вновь закроется, совершив вокруг своей оси поворот на триста шестьдесят градусов.

 Давайте же, ребята. -сказал Джабба.  - Вы же учились в колледжах. Ну, кто-нибудь. Разница между ураном и плутонием.

 Нет, коммандер! - вскрикнула Сьюзан.  - Нет. Хейл сжал ее горло.

Они стали параноиками. Они внезапно стали видеть врага в. И мы, те, кто близко к сердцу принимает интересы страны, оказались вынужденными бороться за наше право служить своей стране. Мы больше не миротворцы.

 - Она кокетливо улыбнулась Беккеру.  - Не волнуйтесь, он ни слова не понимает по-испански. Беккер нахмурился.

Когда его обвиняли в фаворитизме, он в ответ говорил чистую правду: Сьюзан Флетчер - один из самых способных новых сотрудников, которых он принял на работу. Это заявление не оставляло места обвинениям в сексуальном домогательстве, однако как-то один из старших криптографов по глупости решил проверить справедливость слов шефа. Однажды, в первый год своей работы в агентстве, Сьюзан заглянула в комнату новых криптографов за какими-то бумагами. Уже направляясь к двери, она увидела свое фото на доске объявлений и едва не лишилась чувств.

Сьюзан опасливо огляделась.

Поэтому такая перспектива даже не обсуждалась. Сьюзан старалась сохранять самообладание. Мысли ее по-прежнему возвращались к сотруднику лаборатории систем безопасности, распластавшемуся на генераторах.

Ее молитва была проста: она просила Бога защитить любимого человека. Не будучи религиозной, она не рассчитывала услышать ответ на свою молитву, но вдруг почувствовала внезапную вибрацию на груди и испуганно подскочила, однако тут же поняла: вибрация вовсе не была рукой Божьей - она исходила из кармана стратморовского пиджака. На своем Скайпейджере он установил режим вибрации без звонка, значит, кто-то прислал коммандеру сообщение.

 - И если уж попала туда, куда стремилась, постарайся выглядеть на все сто. Сьюзан сладко потянулась и взялась за. Она загрузила программу Следопыт и, приготовившись отправиться на охоту, взглянула на адрес электронной почты, который вручил ей Стратмор. NDAKOTAARA.

Integration testing of Complex Embedded systems CES and associated interconnection network has not been discussed much in the literature. This paper models EPC as a deterministic FSM and describes its fault model that captures errors in the interface between the Hardware and software. An example shows that the integration testing of two subsystems is a subset of general fault diagnostic problem and the faulty machine can be identified during integration. Unable to display preview.
