Turbocharger key parameters

①A/R

Iyo A/R kukosha kwakakosha kuita parameter kune turbines uye compressors. R (Radhiyasi) chinhambwe kubva pakati peturbine shaft kusvika pakati pegiravhiti ye

themuchinjika-chikamu cheturbine inlet (kana compressor outlet). A (Nzvimbo) inoreva mhiri-chikamu nzvimbo ye turbine air inlet (kana compressor air outlet) inoenderana nepamusoro.

centre of gravity point. Chiyero chinowanikwa nekupatsanura A neR uye chigovaniswa ne25.4 ndiyo A/R kukosha.

①Pressure ratio π

Zvinoreva chiyero cheiyo compressor outlet pressure kune compressor inlet pressure.

π=Mushure meP pressure/Pamberi peP pressure

P pressure inoreva kudzvinyirirwa kwakazara pakubuda kwecompressor (kPa)

P dzvinyiriro inoreva kumanikidzwa kwakazara pakupinza kwe compressor (kPa)

②Kuyerera kwemhepo

Zvinoreva huremu hwegasi rinoyerera kuburikidza necompressor per unit nguva. Chikamu chayo ikg/s (chikamu chebhenji bvunzo iri kg/h).

③Kushanda kwesupercharger

Kukwana kwese kwechaja kunoreva chiyero chesimba rinobuda remuchaja kune simba rekupinza. Icho chigadzirwa checompressor kunyatsoita, turbine kunyatsoshanda

uye mechanical kunyatsoshanda.

④Gadzirisa

The Trim value inoreva reshiyo ye sikweya ye dhayamita yemhepo inopinza kune sikweya ye dhayamita yekubuditsa mweya ye compressor impeller, yakapetwa ne 100. The turbine trim value is

yakaverengerwa nekuenzanisa sikweya yedhayamita yechiteshi chekuburitsa neskweya yedhayamita yechiteshi chekupinza uye ichiwedzera nezana.

⑤Pressure ratio π

Zvinoreva chiyero cheiyo compressor outlet pressure kune compressor inlet pressure.

π=Mushure meP pressure/Pamberi peP pressure

P pressure inoreva kudzvinyirirwa kwakazara pakubuda kwecompressor (kPa)

P dzvinyiriro inoreva kumanikidzwa kwakazara pakupinza kwe compressor (kPa)
