Lambda 1.00 ka theek matlab kya hai?

Utni hi hawa jitni saara fuel jalane ke liye chahiye, dono taraf kuchh bacha nahi. Three-way catalyst ko yahi ratio chahiye, isliye closed-loop cruise wahin baithta hai.

Full throttle par kaunsa AFR target karein?

Naturally aspirated petrol engine par lagbhag lambda 0.85 se 0.88, aur turbo par 0.75 se 0.82 — rich mixture charge thanda karta hai aur knock door rakhta hai. Petrol mein ye lagbhag 12.5:1 aur 11.8:1 hai.

E85 ka stoichiometric ratio itna kam kyun hai?

Ethanol apne saath oxygen laata hai, isliye har kilo fuel ko poora jalane ke liye kam hawa chahiye. Isiliye same power ke liye E85 ko lagbhag 30% zyada flow chahiye.

Kya equivalence ratio hi lambda hai?

Ye uska ulta hai. Phi = 1/lambda, isliye phi 1.2 aur lambda 0.833 ek hi rich mixture hain. Research paper phi likhte hain, calibration tool lambda.

Kya narrowband sensor ye numbers de sakta hai?

Nahi. Narrowband sirf itna batata hai ki mixture stoichiometric ke rich ya lean taraf hai, uske aage koi kaam ka resolution nahi. Asli AFR ya lambda wideband se hi aata hai.

Air-Fuel Ratio Calculator ke baare mein

Air-fuel ratio ka matlab tabhi banta hai jab pata ho ki tank mein kya hai. Petrol 14.7:1 par, E85 lagbhag 9.8:1 par aur methanol 6.4:1 par stoichiometric jalta hai, isliye wahi 12.5:1 reading ek fuel par rich aur doosre par khatarnak roop se lean hoti hai. Lambda isse suljhata hai: naapi hui ratio ko stoichiometric se baant kar aisa number deta hai jiska matlab har jagah ek hai — 1.00 stoichiometric, neeche rich, upar lean. Ye calculator das fuel aur kisi bhi ethanol blend ke liye AFR, lambda aur phi ke beech aasani se badalta hai.

Features

AFR, lambda aur equivalence ratio kisi bhi disha mein badalta hai
Das fuel — petrol, diesel, methanol, LPG, CNG aur hydrogen tak
Kisi bhi ethanol blend ka stoichiometric ratio, percentage par interpolate
Rich, lean ya stoichiometric ka faisla aur percentage mein antar
Aam tuning target lambda aur AFR dono mein
Ek lambda reading har fuel ke AFR mein badli hui
Tuning log ke liye copy karne layak summary

Air-Fuel Ratio Calculator kaise use karein

Chuniye ki aap AFR, lambda ya phi se shuru kar rahe hain
Apne wideband ya log ki reading daaliye
Fuel chuniye ya ethanol percentage likhiye
Badle hue values aur stoichiometry se doori padhiye

Example

Input

AFR 12.5 on gasoline

Output

Lambda 0.850 · phi 1.176 · 15% rich of stoichiometric

Wahi lambda E85 par 8.30 AFR hoga — isliye tuner lambda mein kaam karte hain.

Common errors aur troubleshooting

E85 par jaane ke baad wideband ka AFR galat lagta hai. — Zyadatar gauge AFR ko petrol ke fix stoichiometric value par dikhate hain. Sensor lambda naapta hai — E85 ke aankde se badliye aur number theek lagega.
Lambda aur phi ulti disha mein chalte dikhte hain. — Ye paribhasha se reciprocal hain. Lambda 1 se upar lean hai aur phi 1 se upar rich; combustion sahitya phi likhta hai, engine tuning aksar lambda.
Pump fuel ka stoichiometric aankda spec se mel nahi khata. — Zyadatar bazaar mein pump petrol mein pehle se ethanol hota hai. E10 14.7:1 ke bajaye lagbhag 14.1:1 par hota hai — ethanol percentage wala field istemal kijiye.
Diesel ki reading bahut lean lagti hai. — Ye samanya hai. Diesel bina throttle chalte hain aur idle par lambda 5 se upar hote hain; unhe fuelling se control kiya jaata hai, isliye lean number petrol jaisi chetavni nahi hai.
