1 Turboblower
2 Waste gate
3 Lubricating circuit branch
4 Pneumatic actuator
The oil used eliminates part of the large amount of heat yielded by the exhaust gas to the
turbine. The turboblower incorporates a WASTE - GATE valve (2) controlled by a pneumatic
actuator (4), which makes it possible to choke the exhaust gas flow to the turbine, depending
on the pressure reached at the compressor outlet.
BORG WARNER VNT 90 HP turboblower
The 1.3 MJTD, 90 HP engine features a new generation of turboblowers: the VNT (Variable
Nozzle Turbines) turboblower. The distributor blades are actuated electro-pneumatically. This
technology makes it possible to achieve optimum turboblower with all engine speeds.
