4.1 1 CHHS is burned in an ratio. Dry analysis of the exhaust gives the following a air-fuel volume percents: CO₂ = 14.957; Cullg = 0.75% CO = 0%; H₂ = 0%; O₂ = 0%, with the rest being N₂. 02 1 Write the balance chemical equation for one mole of this fuel at these conditions. Co Calculate : 2. a_Air_fuel ratio b. Equivalence ratio. )

Write the complete combustion reaction of fuel oil with atmospheric air. The fuel has the following mass composition: C = 85.5%, H = 10.6% and S = 3.9%. Calculate the content of CO₂ and SO₂ in volume, on a dry basis.

fuel and combustion

The primary difference between these non-road (off road) types of diesel fuel is one contains a red dye and one does not. Otherwise the two diesel fuels are relatively identical.  In some states there may be a higher level of sulfur in the off road diesel.  From a regulatory perspective, the off road diesel tank is not regulated and is not required to have the leak detection, spill prevention or overfill prevention that a regulated tank is.  Why is regular diesel fuel regulated (underground storage tanks) and off-road not regulated?

Q6. Answer following questions by True or False 1. Injector that sprays into the intake system operate at the same pressure of the carburetor. 2. Swirl in the cylinder enhances the mixing of air and fuel to give a homogeneous mixture in the very short time. 3. Flame development region is consumed 80% of the air-fuel mixture. 4. Maximum temperature and pressure of flame propagation occurs somewhere between 20" and 30° aTDC for a four-stroke cycle. 5. Knock caused by self-ignition could occur in S1 engines as well as in CI engines. 6. Detonation is the minimum combustion time possible without actually having an instantaneous constant-volume reaction. 7. Combustion in a CI engine is a flame front moving through a homogeneous mixture. 8. Fuel injection time in CI engine is usually starting at about 15° bTDC and ending about 5° aTDC. 9. Exhaust blowdown occurs when the exhaust valve starts to open somewhere around 60° to 40° bTDC. 10. The average temperature in the exhaust system of a…
