Mean Velocity of Gas through IC Engine Port given Velocity of Piston Solution

STEP 0: Pre-Calculation Summary

Formula Used

Velocity of Gas through Port = (Cross Section Area of Piston*Mean Piston Speed)/(Area of Port)
v_p = (a*s_p)/(a_p)
This formula uses 4 Variables

Variables Used

Velocity of Gas through Port - (Measured in Meter per Second) - Velocity of Gas through Port is the velocity with which the gases are flowing through the port.
Cross Section Area of Piston - (Measured in Square Meter) - Cross Section Area of Piston is the area of the circular cross section of an IC Engine piston.
Mean Piston Speed - (Measured in Meter per Second) - Mean Piston Speed is the average speed of the piston over one engine revolution.
Area of Port - (Measured in Square Meter) - Area of Port is the area of opening of a port.

STEP 1: Convert Input(s) to Base Unit

Cross Section Area of Piston: 622.75 Square Millimeter --> 0.00062275 Square Meter (Check conversion here)
Mean Piston Speed: 4.5 Meter per Second --> 4.5 Meter per Second No Conversion Required
Area of Port: 1240 Square Millimeter --> 0.00124 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

v_p = (a*s_p)/(a_p) --> (0.00062275*4.5)/(0.00124)

Evaluating ... ...

v_p = 2.25997983870968

STEP 3: Convert Result to Output's Unit

2.25997983870968 Meter per Second --> No Conversion Required

FINAL ANSWER

2.25997983870968 ≈ 2.25998 Meter per Second <-- Velocity of Gas through Port

Ports vs Valves in IC Engine

A Port is the best and simplest one to suck the air or air-fuel mixture into the cylinder and kick the exhaust out. Ports are used in two-stroke reciprocating petrol engines and also in rotary engines. Valves are mainly used in 4 strokes reciprocating diesel/petrol engines, etc. Valves need a cam and rocker arm mechanism for the opening and closing of valves. But in the case of ports, it does not need any other mechanism for the opening and closing of ports. It simply opens and closes by the piston (positioning).
