if i have calorific value of mixture, volume at time of compression, bore diameter, can i know the pressure being exerted on the pistons due to the combustion?
The thermodynamic equation for combustion in a spark ignition engine is the ideal gas law, which states that the pressure (P), volume (V), and temperature (T) of a gas are related by the equation PV = nRT, where n is the number of moles of gas and R is the gas constant.
The thermodynamic equation is used in spark ignition engines to calculate the amount of work done by the expanding gases during the power stroke. This work is then converted into mechanical energy to power the engine.
The thermodynamic equation in a spark ignition engine can be affected by factors such as the air-fuel ratio, engine speed, and spark timing. These factors can change the pressure, volume, and temperature of the gas, thus altering the equation.
The thermodynamic equation is important in spark ignition engines because it helps engineers optimize the engine's performance and efficiency. By understanding the relationship between pressure, volume, and temperature, they can make adjustments to improve the engine's operation.
Some limitations of the thermodynamic equation in spark ignition engines include the assumption of ideal gas behavior, neglecting the effects of heat transfer and friction, and not accounting for the chemical reactions that occur during combustion. These limitations can affect the accuracy of the equation in real-world engine conditions.
