bhai i read it & that's why i am advising him to switch to cng as soon as possible.
i am not talking only for paper reserach,i had good result practical experience with cng(& even on pw, fropm long time i try to convince people for cng) infact i am proud user of cng from more than last 11 years ,
i tried it on several cars & all of them gave good results
bhai i dont undetsand why do u say "u dont trt cng at lahore" 1. i have tryied from lahore main city from a long time, never have a complain
bhai cng is cng wether, u fill from khi,lhr or isb, just like ur petrol same wether u fill from lhr or khi( all these r standardized by govt. regulatory bodies)
dont mind, i am telling you on my personal experience that your claim is not right of 100-110 in 55kg or whatever cylinder in corolla.. 55kg cylinder fills up in 7-8 kg of gas.. So if u say 14km/kg then 8*14=112..
i think u wanna prove that corolla goes 8 km per 1 kg,that's wrong calculation
now as u ask for maths, so being as engineer i am happy to prove it mathematically
55 kg cylinder means easily 8-8.2 kg
if your car is properly tuned then it can go easily with a/c around 125-130 + within city within crowd
my recently bought Xli 2006 have 50 kg cylinder & with a/c within city like khi with lots of crowd it easily gives me 130km & even after that some gas remain,car doesnot stops(but as red light of cng comes) then for safe side, i never tried to drive more, i try to rush to cng station soon before engine shuts off,,& this car i have not done still tuning & servicing otherwise average may improve
so if there is 55 kg,it must be given upto 135-140
THE SIMPLE THING I WANT TO REMOVE MISCONCEPT THAT MIELAGE AFFECTS WITH CNG, IT IS SAME MIEALGE AS U GET WITH PETROL/DIESEL ONLY FUEL CHANGES NO MIELAGE AT ALL
IF YOUR CAR IS GIVING 100-110 with 55 kg THEN IT MEANS VERY VERY BAD CONDITION, BAD DRIVE CONDITIONS so immediately check your engine as well as cng, & mind it that if on cng it gives app. 12 km/kg same it will give 12 km/Litre.
reaserach work wether by paper or any means should be welcome with open heart & doesnot mind if any new thing gives education,there is no limit/age to education
i am also suggesting him that dont touch engine, ORIGINALITY NEVER COMES BACK how much good engine or mechanic u have, that's why just install cng in 350-45,000 max. & save self as well as country's economy
