Force Required to Lift Engine Valve Solution

STEP 0: Pre-Calculation Summary

Formula Used

Force to Lift Engine Valve = Stiffness of Valve Spring*Lift of Valve
P₂ = k*h_max
This formula uses 3 Variables

Variables Used

Force to Lift Engine Valve - (Measured in Newton) - Force to Lift Engine Valve is the amount of force (a push or pull upon the valve) that is required to lift the valve.
Stiffness of Valve Spring - (Measured in Newton per Meter) - Stiffness of Valve Spring is a measure of the resistance offered by an elastic valve spring to deformation, every object in this universe has some stiffness.
Lift of Valve - (Measured in Meter) - Lift of Valve is the height to which the valve is lifted during operation for the flow of gases.

STEP 1: Convert Input(s) to Base Unit

Stiffness of Valve Spring: 9.3 Newton per Millimeter --> 9300 Newton per Meter (Check conversion here)
Lift of Valve: 11 Millimeter --> 0.011 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P₂ = k*h_max --> 9300*0.011

Evaluating ... ...

P₂ = 102.3

STEP 3: Convert Result to Output's Unit

102.3 Newton --> No Conversion Required

FINAL ANSWER

102.3 Newton <-- Force to Lift Engine Valve

(Calculation completed in 00.004 seconds)

Force to Lift Engine Valve = Stiffness of Valve Spring*Lift of Valve
P₂ = k*h_max

Working of Valve Spring

The purpose of the valve spring is to exert a force on the rocker arm in order to maintain contact between the follower and cam at the other end. During the suction stroke, the initial spring force keeps the valve closed against negative pressure inside the cylinder. The total force acting on the spring of the exhaust valve consists of two factors, viz., the initial spring force and force required to lift the valve.

How to Calculate Force Required to Lift Engine Valve?

Force Required to Lift Engine Valve calculator uses Force to Lift Engine Valve = Stiffness of Valve Spring*Lift of Valve to calculate the Force to Lift Engine Valve, The Force required to lift engine valve is the amount of extra spring force over the initial spring force that is required to lift the valve. Force to Lift Engine Valve is denoted by P₂ symbol.

How to calculate Force Required to Lift Engine Valve using this online calculator? To use this online calculator for Force Required to Lift Engine Valve, enter Stiffness of Valve Spring (k) & Lift of Valve (h_max) and hit the calculate button. Here is how the Force Required to Lift Engine Valve calculation can be explained with given input values -> 131.502 = 9300*0.011.
