I have noticed turbochargers for diesel applications to have their turbine wheel diameter to be more generously sized as their petrol/gasser engine counterparts. Diameter increase of turbine wheel over compressor wheel varies from about 10% up to 30%.
Gasser turbo's have somewhat equally sized compressor and turbine wheel diameters.
Can someone please shed light into this what factors are at play, when comparing diesel vs. gasser?
Furthermore, why on some diesel applications the turbine wheel is a mere 10% larger than compressor wheel, whereas sometimes the size difference is quite remarkable?
