It would be the one closest to the front.
I have a 149 cc engine on my lawnmower and it has ( 1 ) piston
A piston in an engine functions as a class 1 lever. The piston moves up and down inside the cylinder, converting the pressure from the combustion process into mechanical energy that drives the engine. The force from the expanding gases acts on the piston (effort), which then creates a turning effect on the crankshaft (load).
A bent engine piston is a reference to the piston rod. The piston cannot be bent, but the piston rod can be bent.
1. Piston engine fighter planes.
Closest to serpentine belt.
Cylinder #1 is always the piston closest to the front of the engine(on a transverse mounted engine the side with the belts is the front). If it is a "V" style engine then you will notice that One cylinder head sits closer to the front of the engine than the other. The front cylinder on that side will be number 1.
Passengers side front cylinder on engine is #1.Passengers side front cylinder on engine is #1.
piston is a plunger that moves ups and down in the engine block.the function of the piston is to compress air mixtures in the engine block
The front cylinder on the driver's side is #1.
piston
The volume between the engine head and piston when the piston is in the head dead center piston R - is expressed in cubic inches
Running an engine with broken piston rings will cause damaging scoring in the piston chamber, and is not to be recommended.
