My Hyundai Santro 2008 Prime AC is cooling more on CNG than Petrol but it should be vice versa or atleast same.
chalo bae allah ka shukar karo
does it idle faster on cng?
there is no concept of IDLE in my car. It works all the time i manually turn it off when i feel its cold enough and then turn it back on when needed.
Sir idle means your car rpm when it is start and in rest condition.
Is it constant on petrole or not
Is your car rpm more on gas than on petrole.
Is it smooth on petrol or smooth on gas
No concept of idle? LOL! When you start you car and you are not giving it throttle which means you are not pressing the accelerator and car's engine is running it means it's idling. Is your car having RPM gauge? If not first start your car on petrol and listen to the engine noise. Then convert it to CNG and listen the engine noise again. Come back here and mention difference of engine noise on both CNG and petrol here. If it is having RPM gauge check the RPM on petrol first then on CNG.
Bro Santro has no RPM Gauge. Engine produces more noise on CNG than Petrol. and its smooth on both but sometimes in first gear when i accelerate with soft feet it feels like as if have pressed the accelerator hard. This never happens on CNG.
Pardon me as i am total noob in this that's why i am here
Your RPM is either too high on CNG or too low on petrol.
