the explosions which are caused by the throttle being pushed down and the harder you push down the throttle the bigger the explosion ANSWER for single piston , power stroke force the piston to bdc . but during any other stroke , the inertia of the spinning crankshaft force the piston to tdc n bdc
Bad piston rings. Get new engine.
The typical causes are worn piston rings or valve guides.
Steam pressure pushes the piston up. Atmospheric Pressure pushes the piston down.
Blow by is caused when combustion gases get past the piston into the crank case. The cause will be piston, rings, or cylinder wall.
The piston is moved by the connecting rod which in turn is moved by the crankshaft. It is only on the power stroke that the piston moves the connecting rod, crankshaft and all the rest of the engine, in all the other strokes the engine, crankshaft and connecting rod move the piston.
It could be a few things. Mostly likely a leaking head gasket, worn out piston, piston rings or cylinder.
Yes, any piston engine draws air in when the piston move downward on the intake stroke, and as a result does create a lower pressure with respect to the atmospheric pressure around the engine.
Rotor "Out of Round" when rotating "High" spot will cause piston to retract into caliper body

B. exhaust
Steam under pressure is the short answer
A bent engine piston is a reference to the piston rod. The piston cannot be bent, but the piston rod can be bent.
