Does your engine whistle when you accelerate? Can you hear a squeal from the turbo charger?

Excessive oil loss and smoke from your exhaust pipe can be signs that your turbo needs replacing. Auto Experts Medway in Chatham near Rochester and Gillingham in the centre of Medway is the garage to use.

What is a Turbocharger?

A turbocharger, or turbo is a turbine-driven forced induction device that increases an engine’s efficiency and power by forcing extra air into the combustion chamber. It improves output because the turbine can force more air, and proportionately more fuel, into the combustion chamber than a normal aspirated engine.

How does an engine work?

In normal piston engines, intake gases are “pushed” into the engine by atmospheric pressure filling the volumetric void (vacuum) caused by the downward stroke of the piston.
The downward stroke of the piston creates a low-pressure area, similar to drawing liquid using a syringe.

Why use a Turbocharger?

The objective of a turbocharger is to improve an engine’s efficiency by increasing the density of the intake gas or air, This allows more power per engine cycle.

Common faults:

The most common reason why a turbo might fail is due to lack of oil to the turbo. Poor maintenance of an engine can be a key factor with early turbo failures. The turbo vanes can get damaged through the bearing becoming worn because of a lack of oil or poor oil quality. A worn bearing will effect the spinning of the turbo blades and may begin the squeal. Turbo squeal should not be confused with turbo whistle, which is air whistling through the turbo vanes. A squeal is literally the vanes spinning at more than 4,000 rpm and contacting the turbo casing.
Modern turbochargers can use wastegates or blow-off valves.

A wastegate is a valve that diverts exhaust gases away from the turbine wheel in a turbocharged engine system. The primary function of the wastegate is to regulate the maximum boost pressure in turbocharger systems, to protect the engine and the turbocharger.

How to preserve your Turbo:

The best way to help prevent your turbo from wearing is firstly to allow your engine to warm up fully before overexerting it. The Turbo is lubricated by oil feed pipes and when the engine is cold oil is thicker and the lubrication process is not as efficient compared with when the engine is warm. Allowing the engine to warm up naturally will help the life span of a turbo, as will regular oil changes and using oil flushing additives to keep the oil ways clear.
