Carburetor , also spelled carburettor , device for supplying a spark-ignition engine with a mixture of fuel and air.

Components of carburetors usually include a storage chamber for liquid fuel, a choke, an idling or slow-running jet, a main jet, a venturi-shaped air-flow restriction, and an accelerator pump.

The quantity of fuel in the storage chamber is controlled by a valve actuated by a float. The choke, a butterfly valve, reduces the intake of air and allows a fuel-rich charge to be drawn into the cylinders when a cold engine is started.

As the engine warms up, the choke is gradually opened either by hand or automatically by heat- and engine-speed-responsive controllers. The fuel flows out of the idling jet into the intake air as a result of reduced pressure near the partially closed throttle valve. The main fuel jet comes into action when the throttle valve is further open. Then the venturi-shaped air-flow restriction creates a reduced pressure for drawing fuel from the main jet into the air stream at a rate related to the air flow so that a nearly constant fuel-air ratio is obtained.

The accelerator pump injects fuel into the inlet air when the throttle is opened suddenly. In the s, new legislation and consumer preferences led automobile manufacturers to improve fuel efficiency and lower pollutant emissions. To accomplish these objectives, engineers developed fuel injection management systems based on new computer technologies.

Soon, fuel injection systems replaced carbureted fuel systems in virtually all gasoline engines except for two-cycle and small four-cycle gasoline engines, such as those used in lawn mowers.

How do you rebuild or overhaul a small engine carburetor?

Carburetors are a mechanical component of an engine. They are responsible for delivering a metered amount of air and fuel supply to an engine to sustain proper engine operation. Making any carburetor adjustment has become a thing of the past. Over the years, carburetors have evolved and have become a fundamental part of emissions control. Most carburetors made after no longer feature mixture adjustments because of emissions compliance. This design simplifies production and ensures tuning or adjustments are not necessary, and keeps the engine compliant. Current carburetors feature fixed jets which are specifically calibrated to an engine family and application.

How to Troubleshoot Carburetors and Fuel System Concerns

Танкадо не говорил, он показывал. Он открывал секрет, открывал ключ к шифру-убийце - умоляя, чтобы люди его поняли… моля Бога, чтобы его секрет вовремя достиг агентства. - Три, - прошептала она, словно оглушенная. - Три! - раздался крик Дэвида из Испании. Но в общем хаосе их никто, похоже, не слышал. - Мы тонем! - крикнул кто-то из техников. ВР начала неистово мигать, когда ядро захлестнул черный поток.

 Я не собираюсь тебя убивать.

Теперь только один человек в АНБ был по должности выше коммандера Стратмора - директор Лиланд Фонтейн, мифический правитель Дворца головоломок, которого никто никогда не видел, лишь изредка слышал, но перед которым все дрожали от страха. Он редко встречался со Стратмором с глазу на глаз, но когда такое случалось, это можно было сравнить с битвой титанов. Фонтейн был гигантом из гигантов, но Стратмора это как будто не касалось.

ГЛАВА 22 Дэвид Беккер быстро подошел к койке и посмотрел на спящего старика. Правое запястье в гипсе. На вид за шестьдесят, может быть, около семидесяти. Белоснежные волосы аккуратно зачесаны набок, в центре лба темно-красный рубец, тянущийся к правому глазу.

Молчание. - Мидж. Ты меня слышишь. От ее слов повеяло ледяным холодом: - Джабба, я выполняю свои должностные обязанности.

What is Carburetor – Parts and Working?

Если же нет, то позвони электрикам. - Джабба, дело очень серьезное. У меня чутье. У нее чутье. Ну вот, на Мидж снова что-то нашло.

Электричество. Окрыленная надеждой, Сьюзан нажала на кнопку. И опять за дверью что-то как будто включилось. Она услышала, что в кабине работает вентиляция.

Она почувствовала, как по спине у нее пробежал холодок. Лицо коммандера выражало торжественную серьезность. Видимо, в его действиях было нечто такое, что ей знать не полагалось. Сьюзан опустилась на стул. Повисла пауза.
