Downward Inertia Force on Exhaust Valve as it Moves Upwards Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inertia Force on Valve = Mass of Valve*Acceleration of Valve
P = m*a_v
This formula uses 3 Variables

Variables Used

Inertia Force on Valve - (Measured in Newton) - Inertia Force on Valve is the force acting opposite to the direction of valve motion onto the valve.
Mass of Valve - (Measured in Kilogram) - Mass of Valve is the mass (a measure of the amount of matter in valve) of the valve.
Acceleration of Valve - (Measured in Meter per Square Second) - Acceleration of Valve is the acceleration with which the valve opens or closes.

STEP 1: Convert Input(s) to Base Unit

Mass of Valve: 0.45 Kilogram --> 0.45 Kilogram No Conversion Required
Acceleration of Valve: 140 Meter per Square Second --> 140 Meter per Square Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = m*a_v --> 0.45*140

Evaluating ... ...

P = 63

STEP 3: Convert Result to Output's Unit

63 Newton --> No Conversion Required

FINAL ANSWER

63 Newton <-- Inertia Force on Valve

(Calculation completed in 00.020 seconds)

Engine Valve Materials

The inlet valve is subjected to comparatively less temperature than the exhaust valve. Therefore, inlet valves are made of nickel-chromium steel. The exhaust valves are made of heat-resistant silicon–chromium steel. For heavy-duty engines, valves are made of chromium-vanadium steel. The valves are heat treated and surface hardness for inlet and exhaust valves is in the range of 250 to 300 HB.
