This popular unit is a must for any turbo diesel 4WD ie factory or after market.

They allow the engine to run for a selected period after the ignition is switched off. This allows for the turbocharger unit to cool down to a suitable temperature before switch off. This prolongs the life of the turbocharger bearings and seals. It is particularly important when towing, where the engine has been on boost up a long hill and a stop is required for fuel or a break.



What is a Turbocharger?

  • A turbocharger is a combination Turbine & Compressor joined by a common shaft.
  • Super-hot exhaust gases from the engine pass through the Turbine, causing it (and the Compressor) to spin at high speeds.
  • The Compressor draws air through the air cleaner, compresses and feeds it to the engine for mixing with fuel.
  • The result of these events is greater volumes of air/fuel mixture entering the cylinders.
  • The engine, as a direct result, delivers considerably more power and torque than an identical capacity engine taking in air at normal atmospheric pressure.

 


Why Turbochargers Need Protection

  • The waste gases which drive the Turbine come direct from the combustion chambers via the exhaust manifold at temperatures which can lift the Turbine to over 700º C.
  • The Turbine spins at up to 100,000 RPM.
  • The Turbo shaft and bearings and the oil which lubricates them must withstand these conditions on a daily basis for long periods at a time.
  • At switch-off, Turbo temperature is high & lubrication to the bearings stops instantly.
  • Unless special precautions are taken, this may result in thermal distortions, the varnishing of oil on the shaft and bearings and premature Turbo failure.


How to Protect your Turbocharger

Turbo engine manufacturers recommend that, after a brisk run, their engines be idled for a few minutes to allow the Turbocharger to slow down, cool and normalise while maintaining a flow of fresh engine oil to its bearings. This routine, if followed at every switch-off, will extend Turbo life and significantly reduce the likelihood of premature Turbocharger failure. 


Automatic Turbo Protection

The most popular and foolproof method of guaranteeing that the engine manufacturer’s recommendation is carried out every time you switch off is to fit a Bogaard Turbo Timer. Many thousands are fitted to all types of vehicles; cars, 4WD's, trucks, even tractors & lawnmowers. Bogaard Turbo Timers are inexpensive, foolproof & fail-safe. They are easy to fit, with plug-in models for most popular vehicles. 


Owners Manual Extract
Watercooling of turbochargers does not remove the need to idle down. The following is an extract from the Owner’s Manual for a car with a water cooled Turbocharger produced by one of Australia’s biggest manufacturers:


"It is essential to maintain a clean supply of oil flowing through the Turbocharger system as a sudden interruption of oil supply may cause a malfunction to the Turbocharger. Therefore, if the engine has been operating at high load or high RPM for an extended period of time, let it idle for a few minutes prior to shutdown."
