Cylinder piston friction

Answer / sriram_veluri

some of the causess for major losses in efficiency are
1.improper compression
2.improper closing and openinig of valves (valve timing)
3.friction between piston and cylinder

Answer / paresh

heat loss

Answer / arjun

incomplete combustion of fuel and friction

Answer / shahnawaz

1)incomplete combustion of fule
2)friction between Piston & Clyinder
3)knocking
4)heat in engin
5)without good lubricant

Answer / radhe shyam

1.friction between piston & waLL
2.improper air fuel ratio
3.back flow of fuel
4.faulty timing of valve system

Answer / panni kutti

incomplete combustion also main responsible for loss in
efficiency....

Answer / sanket

the cause of major loss in efficiency of an IC engine is
heat loss in exhaust gases about 35-40% of total fuel
energy.

Answer / bejoy

the energy in an IC engine is produced by the burning of
fuel in each power stroke..inefficiency is created in many
steps..
much of this heat energy is lost with exhaust gas,by
convection,conduction and radiation from the cylinder..only
some of it is converted to useful energy i.e in pushing the
piston down rapidly..this is the major cause of inefficiency
in IC engines.. after ehich various mechanical losses like
friction comes in...

Answer / ravi

in ic engine heat energy is utilised.& it is low grad
energy.so, its efficiency is less
