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.
How to Calculate Total Force on Rocker Arm of Exhaust Valve given Suction Pressure?
Total Force on Rocker Arm of Exhaust Valve given Suction Pressure calculator uses Total Force on Rocker Arm of Exhaust Valve = (pi*Back Pressure on Engine Valve*Diameter of Valve Head^2)/4+Mass of Valve*Acceleration of Valve+(pi*Maximum Suction Pressure*Diameter of Valve Head^2)/4 to calculate the Total Force on Rocker Arm of Exhaust Valve, The Total force on rocker arm of exhaust valve given suction pressure is the total force acting onto the rocker arm of the exhaust valve due to gas load, inertia force, and spring force. Total Force on Rocker Arm of Exhaust Valve is denoted by Pe symbol.
How to calculate Total Force on Rocker Arm of Exhaust Valve given Suction Pressure using this online calculator? To use this online calculator for Total Force on Rocker Arm of Exhaust Valve given Suction Pressure, enter Back Pressure on Engine Valve (Pb), Diameter of Valve Head (dv), Mass of Valve (m), Acceleration of Valve (av) & Maximum Suction Pressure (Psmax) and hit the calculate button. Here is how the Total Force on Rocker Arm of Exhaust Valve given Suction Pressure calculation can be explained with given input values -> 1733.935 = (pi*800000*0.05^2)/4+0.45*140+(pi*51000*0.05^2)/4.
