Both the fuels has different compression ratio. or compression ignition engine uses diesel as a fuel. Why We Do Not Use Same Technology To Start Both Si/cl Engine ? Thus weight of coolant gets reduced and smaller radiator can be used.ġ6. Glycerin has boiling point of 90☌ which increases its heat carrying capacity. In Some Engines Glycerin Is Used In Place Of Water For Cooling Of Engine. This way tot of lubrication oil can be saved and used properly.ġ5. What Do You Understand By Timed Cylinder Lubrication?įor effective lubrication, lubrication oil, needs to be injected between two piston rings when piston is at bottom of stroke so that piston rides in oil during upward movement. engines is much higher compared to gas turbine.ġ4. engines have much Lower auxiliary consumption. In gas turbines, 70% of the output of gas turbine is consumed by compressor. Why Efficiency Of Gas Turbines Is Lower Compared To Lc. This condition wilt lead to overheating and failure of the engine.ġ3. That is because of engine running too Lean mixture (lack of fuel). What Causes White Smoke In Two Stroke Locomotive Engines? When you start a V-8 engine, you are only driving two cylinders (1 Liter) through their compression strokes, but with one big cylinder you would have to compress 4 titers instead.ġ2.

A V-8 engine is much smoother because it has eight evenly spaced explosions instead of one big explosion. There are a couple of reasons why a big 4.0-Liter engine has eight half-Liter cylinders rather than one big 4-Liter cylinder. Why Have Eight Cylinders In An Engine? Why Not Have One Big Cylinder Of The Same Displacement Of The Eight Cylinders Instead?

During Idling Process, A Petrol Engine Requires Lean Or Rich Mixture?Ĩ. Because it has smaller size for the same output.ħ. Two stroke engine is generally preferred. Among Two-stroke Engine And Four-stroke Engine Which Is Generally Preferred And Why? are drawn in.įuel vapor and air are compressed and ignition takes place.įuel combustion takes place and piston is pushed downwards.Ħ. Name The Main Steps Involve In 4-stroke I.c Engine? It is the measure of rating of CI engine.ĥ. – Cetane number is defined as the percentage, by volume, of n-cetane in the mixture of n-cetane and alpha methyl naphthalene. It is the measure of rating of SI engine. – Octane number is defined as the percentage, by volume, of iso-octane in the mixture of iso-octane and h-heptane. Definition Of Octane Number And Cetane Number?
