Variable Geometry Turbocharging of a Large Truck Diesel Engine

The paper describes the application to an 11.2ℓ 6 cylinder, D.I. truck Diesel engine of an electronic optimizing control system as part of a major research programme into improving truck Diesel engine performance with respect to

1. a)
   torque back up
2. b)
   part load economy
3. c)
   improved transient response

The parameters under electronic control are:-

1. a)
   turbocharger turbine nozzle ring position
2. b)
   engine governing
3. c)
   injection timing
