what is inducer in turbocharger

by Philip Schultz DDS Published 3 years ago Updated 3 years ago

The main function of inducer in turbocharger are:

  • To feed the shock less airflow to the impeller of the turbocharger.
  • To boost atmospheric air to a higher pressure.
  • To guide the air smoothly into the eye of the impeller.

The inducer in the turbocharger is the smaller part of the compressor wheel that sucks ambient filtered air parallel with the driven shaft compresses it and pushes it out the perpendicular bore of the inducer horn.Jan 12, 2022

What is inducer diameter of a turbocharger?

The inducer diameter (2) forms the limiting flow of the compressor and it is this diameter that is frequently regulated by certain racing bodies to limit turbocharger size and hence the engine’s power output.

What is a turbocharger?

A turbocharger, colloquially known as a turbo, is a turbine -driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra compressed air into the combustion chamber. This improvement over a naturally aspirated engine 's power output is due to the fact...

What is the inducer on a compressor?

The smaller side of the compressor wheel, which is the inlet side of the compressor wheel or front, is the inducer To direct the flow of fresh air towards the center an inducer made of light alloy aluminum steel is fitted just before the impeller.

How does a turbocharger increase the intake pressure?

Only when the engine reaches sufficient speed (rpm) does the turbine section start to spool up, or spin fast enough to produce intake pressure above atmospheric pressure. A combination of an exhaust-driven turbocharger and an engine-driven supercharger can mitigate the weaknesses of both.

What is turbo inducer and Exducer?

* The inducer diameter is defined as the diameter where the air enters the wheel, whereas the exducer diameter is defined as the diameter where the air exits the wheel.

What is a diffuser in a turbocharger?

The turbocharger diffuser is in the compressor side of the supercharger. The diffuser is mounted in the compressor side of the turbocharger in order to direct the air smoothly into volute casing and Convert kinetic energy to pressure energy inlet air.

What are the parts of a turbocharger?

At the most basic level, a turbocharger consists of just three major components: the turbine, the compressor, and the bearing system that supports the turbine shaft, connecting the turbine and compressor wheels together.

What are the two sides of a turbocharger called?

A turbocharger is made up of two main sections: the turbine and the compressor. The turbine consists of the turbine wheel (1) and the turbine housing (2). It is the job of the turbine housing to guide the exhaust gas (3) into the turbine wheel.

What is K value in turbocharger?

Measuring of distance between the rotor shaft end and the flange of bearing cover by blower side is known as K value in Turbocharger. Purpose. In case of thrust bearing worn out, to ensure that rotating impeller does not to touch the stationary blower casing cover.

What is turbo pressure ratio?

The turbocharger can also be provided with a generally optimum boost pressure ratio of about 4.5:1 to 4.6:1. Such a compressor comprises a first axial-compressor stage, typically providing a 1.3:1 pressure boost ratio, and a second radial-compressor stage, typically providing a pressure ratio of 3.5:1.

How many RPM is a turbo?

A turbo spins very fast; most peak between 80,000 and 200,000 RPM (using low inertia turbos, 150,000-250,000 RPM) depending on size, weight of the rotating parts, boost pressure developed and compressor design.

Whats an intercooler do?

As we mentioned before, hot compressed air isn't great for combustion. That's where an intercooler comes in. The intercooler aids this process by cooling the air down before it enters the engine and combustion chamber. Depending on what kind of intercooler it is, the cooling process may be a little different.

How does a wastegate work?

The wastegate is held shut by a spring inside the actuator, but when the boost pressure exceeds the pre-set maximum, it compresses this spring, progressively opening the wastegate. This allows the exhaust gases through, so that they bypass the turbine, regulating its speed.

What is a turbo wastegate?

A wastegate is a valve that controls the flow of exhaust gases to the turbine wheel in a turbocharged engine system. Diversion of exhaust gases regulates the turbine speed, which in turn regulates the rotating speed of the compressor.

What is scavenging air?

Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air/fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle.

What is the center part of a turbo called?

Cast iron housing, the centre of the turbo that houses the turbine piston ring seal, the journal bearing(s) and the thrust bearing, which are all fed with pressurised oil from the engine.
