Description
すなわち、エンジンの最大回転数をNm(rev/min)、増速比をα、音速をVs(mm/s)とすると、下記の(1)式が成立する。
[(Nm×α)/60]×π×Ii>Vs ・・・(1)
本実施形態では音速の1.3倍に設定されるので、入口径Ii(mm)は、つぎの範囲に設定される。
1.3×Vs>[(Nm×α)/60]×π×Ii>Vs
[(1.3Vs×60)/(Nm×π)]>Ii>[(Vs×60)/(Nm×π)]
つまり、本実施形態のように増速後の過給機の最大回転数が毎分14万回転の場合、入口径Iiは45mmを超えて59mm未満が好ましい範囲となる。本実施形態では、入口径Ii(mm)は、52mmに設定される。
That is, when the maximum engine speed is Nm (rev / min), the speed increase ratio is α, and the sound speed is Vs (mm / s), the following equation (1) is established.
[(Nm × α) / 60] × π × Ii> Vs (1)
In this embodiment, since it is set to 1.3 times the sound speed, the inlet diameter Ii (mm) is set to the following range.
1.3 × Vs> [(Nm × α) / 60] × π × Ii> Vs
[(1.3 Vs × 60) / (Nm × π) ]> Ii > [(Vs × 60) / (Nm × π)]
That is, when the maximum number of rotations of the turbocharger after the speed increase is 140,000 rotations per minute as in this embodiment, the inlet diameter Ii is preferably in the range of more than 45 mm and less than 59 mm. In the present embodiment, the inlet diameter Ii (mm) is set to 52 mm.
