With the middle cylinder, its in between the 2 cylinders causing it to become more hot. thats generally why that happens.
The distance a piston travels within the cylinder is called the stroke. It is the distance between the top dead center (TDC) and the bottom dead center (BDC) positions of the piston.
The number one piston is always at the front side of the motor where the belts are. If it is a 4 cylinder. If it is a 6 cylinder its is always the 1st cylinder on the left side of the motor at the front where the belts are. Justin
In a internal combustion engine, a cylinder ridge is an unworn area around the top of the cylinder wall. In that engine, the piston moves up and down in the cylinder, and the rings seal the piston in that cylinder. But the rings are spaced "down a bit" from the top of the piston. And when the piston reaches top dead center in the cylinder, the rings haven't gone all they way to the top of the cylinder. They end up wearing the cylinder out "underneath" that top area. In other words, it's the top part of the cylinder that is not in contact with the piston rings. It's the "unworn" part, if you will.
Bottom dead centre. BDC
the piston in cylinder #1 at the top on the compression stroke
No fit.BECAUSE No contact between piston and cylinder.
Dwell is the angle at which the spark occurs in the cylinder before the piston reaches top dead center.
Dwell is the angle at which the spark occurs in the cylinder before the piston reaches top dead center.
The piston is prevented from tipping in the cylinder by the piston rings, which provide stability and guidance as the piston moves up and down within the cylinder. Additionally, the piston skirt design and cylinder wall clearance also help to maintain proper alignment of the piston during operation.
I have always heard the Jug being referred to as the Cylinder and/or piston assembly including the cylinder.
A blown cylinder on a Polaris snowmobile typically shows signs of severe damage, such as cracks or holes in the cylinder wall, which may allow for air and coolant leaks. You might also notice signs of scoring or burn marks on the piston and cylinder head. Additionally, there could be an accumulation of metal shavings in the oil, indicating internal damage. Overall, the affected components will likely appear charred or excessively worn compared to a normal, functioning cylinder.
AnswerAccording to Timberwoof, the maintainer of the rec.motorcycles FAQ:BDC means Bottom Dead Center, the position closest to the crankshaft that a piston travels in its cylinder. Alternatively, Brain-Dead Cager (refering to a car, cage, driver that is not attentive to the road: especially motorcycles on it). "When the piston hits BDC."TDC means Top Dead Center, the position closest to the cylinder head that a piston travels in its cylinder.YEs...BDC is the lowest point of the cylinder till where the Piston can move and simillarly TDC is the top most point till where the Piston can reach. Both of these are limited by the crankshaft and connecting rods, not the cylinder itself.
