How Turbos Have Changed
OUT WITH THE OLD TURBO, IN WITH THE NEW TURBO How Turbos Have Changed In this week’s waffle I’m talking about the actuator used on the turbocharger on DAF mx-11 and mx-13 since euro 6 Variable Turbo Geometry plays an important part in efficiency and this was one of the big factors for replacement of the old internal waste gate turbocharger. NO SMOKE WITHOUT POKE We have a few components fitted to the turbocharger to enable correct operation as without a waste gate it can literally produce boost till it fails from oil starvation due to shaft speed or in bits from compressor surge, but in this week’s waffle we will focus on the actuator. One of the major components of the turbo is the VTG actuator. This component controls the direction of air via a nozzle ring at the turbine wheel How this operates is to increase the turbo rpm lower down in the rev range or slow it down higher in the rpm range, such as to control exhaust back pressure during exhaust BRAKE application . But having mechan
