Total Length of Piston Solution

STEP 0: Pre-Calculation Summary
Formula Used
Length of Piston = Width of Top Land+Length of Ring Section of Piston+Length of Piston Skirt
L = h1+hR+ls
This formula uses 4 Variables
Variables Used
Length of Piston - (Measured in Meter) - Length of piston is the total length of a piston.
Width of Top Land - (Measured in Meter) - Width of top land is the distance from the top of the piston to the first ring groove.
Length of Ring Section of Piston - (Measured in Meter) - Length of ring section of piston is the length of the part of piston where rings are fitted, from top of first ring to the bottom of last ring.
Length of Piston Skirt - (Measured in Meter) - Length of piston skirt is the total length of a piston skirt used for bearing side thrust.
STEP 1: Convert Input(s) to Base Unit
Width of Top Land: 30 Millimeter --> 0.03 Meter (Check conversion here)
Length of Ring Section of Piston: 44 Millimeter --> 0.044 Meter (Check conversion here)
Length of Piston Skirt: 160 Millimeter --> 0.16 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
L = h1+hR+ls --> 0.03+0.044+0.16
Evaluating ... ...
L = 0.234
STEP 3: Convert Result to Output's Unit
0.234 Meter -->234 Millimeter (Check conversion here)
FINAL ANSWER
234 Millimeter <-- Length of Piston

8 Piston Skirt Calculators

Length of Piston Skirt given Allowable Bearing Pressure
Go Length of Piston Skirt = Coefficient of Friction for Piston Skirt*pi*Diameter of Cylinder Bore*Maximum Gas Pressure inside Cylinder/(4*Bearing Pressure for Piston Skirt)
Side Thrust on Piston
Go Side thrust on piston = Coefficient of Friction for Piston Skirt*pi*Diameter of Cylinder Bore^2*Maximum Gas Pressure inside Cylinder/4
Length of Piston Skirt given Side Thrust
Go Length of Piston Skirt = Side thrust on piston/(Bearing Pressure for Piston Skirt*Diameter of Cylinder Bore)
Side Thrust on Piston Skirt
Go Side thrust on piston = Bearing Pressure for Piston Skirt*Diameter of Cylinder Bore*Length of Piston Skirt
Total Length of Piston
Go Length of Piston = Width of Top Land+Length of Ring Section of Piston+Length of Piston Skirt
Minimum Length of Piston Skirt
Go Length of Piston Skirt = 0.65*Diameter of Cylinder Bore
Maximum Length of Piston Skirt
Go Length of Piston Skirt = 0.8*Diameter of Cylinder Bore
Maximum Total Length of Piston
Go Length of Piston = 1.5*Diameter of Cylinder Bore

Total Length of Piston Formula

Length of Piston = Width of Top Land+Length of Ring Section of Piston+Length of Piston Skirt
L = h1+hR+ls

Main Functions of a Piston

The main functions of the piston are as follows:
(i) It transmits the force due to gas pressure inside the cylinder to the crankshaft through the connecting rod.
(ii) It compresses the gas during the compression stroke.
(iii) It seals the inside portion of the cylinder from the crankcase by means of piston rings.
(iv) It takes the side thrust resulting from the obliquity of the connecting rod.
(v) It dissipates a large amount of heat from the combustion chamber to the cylinder wall.
