Turbochargers Explained: The Wastegate
Dec 16, 2003 | By: Matyas Varga - SRO

40mm External Wastegate

Turbo Wastegate Wastegate

Without a wastegate, the amount of boost that a turbocharger creates
varies with the pressure of the engine's exhaust. This happens because
exhaust pressure varies with relation to the engine's speed (measured
in RPM's). This implies that as an engine reaches higher RPM's,
increasing amounts of boost will be created by the turbocharger. The
problem with this is that an engine can only accomodate a given amount
of boost. Most stock engines are only meant to take about 10 PSI if not
less. In order to regulate the amount of boost that comes into the
engine, a wastegate acts as a door only allowing a given amount of
exhaust to hit the turbocharger's exhaust turbine. Once the engine
starts producing more exhaust pressure then the wastegate system will
allow, a flap is opened to redirect excess exhaust away from the
turbine blades. In turn, this is where a wastegate gets it's name. It's
a gate to carry away waste. In order to regulate when a wastegate
opens, a boost conroller can be used.

Internal Wastegate Assembly and Actuator

Turbo Wastegate Wastegate2

There are two types of wastegates. The first one is an internal
wastegate (right). An internal wastegate is a component on the turbo
unit itself. The gate is opened via an actuator which is a diaphram
type system (see left picture). Excess exhaust is then fed directly
into the exhaust system. We also have what is called an external
wastegate (left), unlike an internal wastegate, it is seperate from the
turbo unit and does not require an actuator. Excess exhaust can either
be fed into the exhaust system or it can be vented straight out and
into the atmosphere. High performance set-ups typically follow the
latter alternative. Most stock systems come with an internal wastegate
as this set-up is better suited for low boost applications. However
most aftermarket systems perform better with an seperate external
wastegate assembly making it an ideal choice for those generating boost
in the range of 20-30 PSI.

blow off ko lepas dia bunyi, kalau w'gate ko tekan sampai full boost baru dia bunyi, makin tinggi boost makin kuat bunyi dia, selagi x full boost dia x bunyi itu w'gate.

turbo boost yg slama ni steady - jadi tidak steady, kena cek blow valve & waste gate kalau lain² tempat nda bocor.
