The exhaust valve opens after completion of combustion. The combustion completes when piston reaches BDC. In modern engine the exhaust valve opens before BDC to run the engine smoothly.

double energy transient, in which electromagnetic and electrostatic energy storage are present, and the transient is either aperiodic or a damped sinusoid.

it is theoretically lowest temperature where the particle constituents of matter have minimal motion and equals 0 kelvin. it is defined by the third law of motion.

Mean effective pressure is the engines capacity to do work independent of engine displacement.
So it is average pressure acting on a piston during the cycle.
The Mean Effective Pressure (MEP) is a theoretical parameter used to measure the performance of an internal combustion engine (ICE).

Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all. The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons ‘orbit’ the nucleus.

In engine the combustion takes place when piston reaches the top dead center. But in actual cycle the ignition starts before piston reaches TDC. This is termed as ignition advance.

The heat passes to cylinder is approximately 30%.

In 4 stroke engine one cycle complete in two revolutions.
In one cycle only one combustion takes place. Hence number of power strokes = 2000/2 = 1000.
The combustion stroke is the third phase, where the ignited air-fuel mixture expands and pushes the piston downwards. The force created by this expansion is what creates an engine’s power.

In 4 stroke engine there are two valves. One intake valve and one exhaust valve.

In diesel engine the fuel is injected to the cylinder at high pressure for combustion. During fuel injection at high pressure the fuel get atomized. Hence combustion takes place efficiently.
