Abstract
The aim of this study is to compare the effectiveness of turbo chargers on engines for off-road use when combined with WGT and VGT technologies. The effectiveness of turbo chargers was measured and performance was compared using a functional model. Exhaust characteristics were compared using WGT and VGT technologies through a gas analyzer. Results showed VGT technology was more effective at high RPM compared to WGT technology. When it came to maximising turbo performance, VGT was more effective than WGT in every test. WGT and VGT produced similar exhaust NOx levels, whereas the VGT was more effective on the PM.
