Initial Spring Force on Valve given Total Force on Rocker Arm of Inlet Valve Solution

STEP 0: Pre-Calculation Summary

Formula Used

Spring Force on Rocker Arm Valve = Total Force on Rocker Arm of Inlet Valve-Inertia Force on Valve
P_sr = P_i-P
This formula uses 3 Variables

Variables Used

Spring Force on Rocker Arm Valve - (Measured in Newton) - Spring Force on Rocker Arm Valve is the force exerted by a compressed or stretched spring upon any object that is attached to it.
Total Force on Rocker Arm of Inlet Valve - (Measured in Newton) - Total Force on Rocker Arm of Inlet Valve is the total force acting onto the rocker arm of the inlet valve.
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.

STEP 1: Convert Input(s) to Base Unit

Total Force on Rocker Arm of Inlet Valve: 200 Newton --> 200 Newton No Conversion Required
Inertia Force on Valve: 115 Newton --> 115 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_sr = P_i-P --> 200-115

Evaluating ... ...

P_sr = 85

STEP 3: Convert Result to Output's Unit

85 Newton --> No Conversion Required

FINAL ANSWER

85 Newton <-- Spring Force on Rocker Arm Valve

What is SI Engine?

A spark-ignition engine (SI engine) is an internal combustion engine, generally a petrol engine, where the combustion process of the air-fuel mixture is ignited by a spark from a spark plug. This is in contrast to compression-ignition engines, typically diesel engines, where the heat generated from compression together with the injection of fuel is enough to initiate the combustion process, without needing any external spark. Spark-ignition engines are commonly referred to as "gasoline engines" in North America, and "petrol engines" in Britain and the rest of the world. Spark-ignition engines can (and increasingly are) run on fuels other than petrol/gasoline, such as autogas (LPG), methanol, ethanol, bioethanol, compressed natural gas (CNG), hydrogen, and (in drag racing) nitromethane.
