u can use pressure sensor at the two extreme position.

Hai, I want to know to the basic criteria to be noted while designing the fuel rail. Is there any special recommendations or standard for designing a fuel rail.

Thanks guys

@Stewartcs, I could see the link which u attached. Kindly don't mistake me. CFM = (CID*RPM*VE)/3456 What is the purpose of 3456? Kindly expain me in detail.

VAF = (Engine Displacement/1728) * (RPM/2) * VE Yes the end unit for this equation is CFM only. But what is the purpose of 1728 or 28.317 in the equation. Without these constant we can achieve the units correctly.

Yes it is the unit conversion data only. But what is the purpose of the 28.317 there. See i am giving the Engine capacity in Litre only, And my end unit of Volume of air is Lit/min only. And also VAF = (Engine Displacement/1728) * (RPM/2) * VE I am still confused on the 28.317?

I want to know how to calculate engine idle air requirement. Engine rpm = 1200 rpm = RPM Rev/cyle = 2 Engine capacity = 395 cc = 0.395 Lit = L Volumetric Efficiency = 90% = VE Then VAF (Volume of Air Flow) is, VAF = (L/28.317) x (RPM/2) x VE. I want o know what is the meaning for...

Hai Molecular mass of air is 29. But this value is 28.317 which is 0.6 lesser than molecular mass of air. I am confused on this 28.317...

Can anyone tell me the method to calculate the engine idle air flow requirement? Engine rpm = 1200 rpm = RPM Rev/cyle = 2 Engine capacity = 395 cc = 0.395 Lit = L Volumetric Efficiency = 90% = VE Then VAF (Volume of Air Flow) is, VAF = (L/28.317) x (RPM/2) x VE. I want o know what is the...

P = Pressure at the region : in Pa R = Specific gas constant R : 287 J/KgK T = Air Temp : in K Density of air = P/(R*T) in Kg/m3

Hai, I have the pressure value (which is less than atm) and temperature value. How to calculate Density of the air? I calculated but the result is not satisfactory.

Can you tell me what are the different types of Level sensors available for CNG cylinder?

As u are telling temperature is also a parameter other than pressure for measuring level in the CNG Cylinder... So i must have a pressure sensor and temperature sensor for measuring Level in cylinder.

Hey, As all of u know CNG Level sensor gives an output of level of CNG in the cylinder. Do pressure of CNG in cylinder is caliberated level ?
