is temperature continue to increase after ignition in cylinder?

Question

I wonder how temperature and pressure increase after ignition in cylinder of auto engine.....
is it just one explosion or a continous explosion (after ignition) throughout the cylinder....increasing the temperature as the burning continue.....

Answer 1

In a gas motor, it is one combustion that forces the piston down.

In a diesel motor, combustion continues as the piston travels downard through the cylinder, this is why they have so much torque

Answer 2

Yes both temoerature and pressure incrase in the cylinder until the exhaust valve opens. One the spark plug fires it only ignites the surronding fuel particles. From then on the remaining fuel in the engine is burnt in a continuous pattern away from the spark plug. it is the further increase in temperature and pressure that push the piston down. Only when the exhaust valve opens does this stop since there is now an opening in the cylinder and pressure can no longer increase.

For a pretty good explaination of this action, go on the internet, punch in < how stuff works.com> then leaf through the auto/engine section (the under the hood/how car engines work section) , they have a very interesting animated video to help explain how both four stroke-cycle, and two stroke-cycle engines work. this will help far more than a short explaination here would. Good luck! Hope this helps. burts chevy.

Answer 4

auto engines run on 4 cycles . intake ,compression, burn and exhauste. during intake the air and fuel is drawn in. all that gets compressed then ignition(burn) then exhaust. after explosion all the burnt fuel and air is exhausted not continous
