But what's the mark down at the bottom to bring the 1 piston to TDC point you mean the mark 4 the cranck shaft?

What is top dead center and bottom dead center in vehicles piston?

The top dead center is when the piston has reached its peak and can go no farther up, it has reached its summit. The bottom dead center is when the piston is at its lowest point.

What is before bottom dead center?

it's the point in the rotation of a internal combustion engine just before the piston reaches the bottom of it's down stroke

Where is dead center on the Distributor of a 1992 Ford Aerostar Van?

Bring #1 piston to its uppermost point and observe position of distributor--it should be firing on no. 1

What is the line of best fit for the piston's data?

the best of piston's the point of graph

What is direction for piston installation on beetle?

Each piston has an arrow on top. Point it at the flywheel end.

What part of a roller coaster goa's faster?

The fastest point of a chain lift will be the bottom of the longest drop. The fastest speed of a launch style coaster is just as the piston stops accelerating the car.

What do BDC and TDC mean in motorcycle jargon?

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.

How do you set the timing on a Dodge 5.2 engine?

bring number 1 piston up to top dead center point rotorbutton to number 1 sparkplug wire on the distributor cap can you get more preformance by the timing

Meaning of cam ground of piston?

Aluminum expands much more than Cast Iron, so when the piston to cylinder wal clearance is measured at room temperature there must an allowance to allow for expansion when the piston heats up. The amount of clearance depends upon the design of the engine and the anticipated operating temperature. Air-cooled engines run very hot so they require more clearance than water-cooled engines. On a Cushman piston the reference point for more clearance than water-cooled engines. On a Cushman piston the reference point for clearance measurements is at the top of the skirt perpendicular to the piston pin All areas of the piston do not expand the same; the top of the piston runs the hottest so it expands the most. The skirt runs the coolest so it expands the least. For this reason the diameter at top of the piston will normally be smaller, and the diameter at the bottom of the skirt will normally be a little larger, than the diameter at the top of the skirt. Also, the piston does not expand the same all the way around its circumference. The diameter measured across the piston pin will expand more than the diameter-measured perpendicular to the piston pin. Therefore, the piston is "cam ground", or made slightly oval, with the smaller diameter measured across the piston pin. When the piston heats up to operating temperature it will then be round. If the piston were not cam ground, the to operating temperature it will then be round. If the piston were not cam ground, the piston to cylinder wall clearance would have to be extremely high when the engine was cold to allow for expansion, and it would not be round when at operating temperature. This could cause piston slap and other problems. piston to cylinder wall clearance would have to be extremely high when the engine was cold piston to cylinder wall clearance would have to be extremely high when the engine was cold to allow for expansion, and it would not be round when at operating temperature. This could cause piston slap and other problems Cushman engines are usually set to a clearance of about .006 inch measured at the reference point described in paragraph one. The clearance at operating temperature will be much less, and if sufficient allowance is not made for expansion, the piston will expand to much less, and if sufficient allowance is not made for expansion, the piston will expand to the diameter the cylinder wall and freeze up. During break-in everything is running extra the diameter the cylinder wall and freeze up. hot due to the increased friction, and the piston temperatures get very high. If the engine is run at high speeds during this period it will almost always freeze up and may damage the run at high speeds during this period it will almost always freeze up and may damage the engine The following measurements are from a Cushman NOS +.030 cam ground piston Top of skirt perpendicular to the piston pin 3.024 (.006 clearance) Top of skirt measured across piston pin 3.011 Bottom of skirt perpendicular to pin 3.025 Bottom of skirt parallel to piston pin 3.012 Top of Piston and ring lands 3.005 In this case the clearance to a nominal 3.000 inch cylinder bore is .006 inch, the elliptica amount is .013, the skirt is .001 larger at the bottom than at the top, and the top of the piston is .019 less than the widest point on the skirt. These measurements are for llustration only and individual pistons may vary considerably

What direction should the arrow point on top of a piston?

in most cases it points to the camshaft

How did the steam engine propel the growth of industry and transportation and help bring about the industrial revolution?

The mechnical idea behind a Steam engine is very simple: Take a Tea Pot and seal it up. Conect an outlet pipe to a Cylinder with a Piston in it. Boil the water The steam will propel the Piston down the cylinder Conect the piston to a crank, say on a Locomotive wheel (Very Small Locomotive if we are using my tea pot) Create a valve system that will allow thew steam in when the piston is ready to push the crank and allow the steam out when the piston is ready to travel back to the start point. Bingo Bango the Steam age has arrived
