Abstract
The paper presents a mathematical model of heat release in a cylinder of a gas engine based on the previously described differential equations proposed by Professor R.M. Petrichenko. Having studied the method for calculating the heat release through pressure buildup during the gas exchange, a number of shortcomings were identified that made it possible to formulate an improved mathematical model of the gas dynamic process in determining the turbulent propagation velocity of the flame front in the combustion chamber of the gas engine, expressing it through the angle of rotation of the crankshaft, which made it possible to optimize the methane- at the inlet.
Highlights
The analysis studies have shown that the most common method of determining the heat dissipation in this case is the use of a mathematical model described by R
Where п0, п - is the number of revolutions of the engine at work in source and design modes; αo, α - coefficient of excess air when operating in source and design modes; Т0,Т - is averaged over the period of combustion temperatures, when you work in source and design modes; V0,V - volume of gas-air mixture entering the cylinder when you work in source and design modes
The analysis of the parameters determining the combustion in the cylinder of a gas engine
Summary
The analysis studies have shown that the most common method of determining the heat dissipation in this case is the use of a mathematical model described by R. Petrichenko [1,21] In it are examines the influence of operating parameters one process of gas exchange a gas engine which takes place inside the cylinder. In this case, the proposed model considers the rate of change of pressure in the cylinder of a diesel engine and does not take into account of some features of the engine as in the structural and thermodynamic relations. The proposed model considers the rate of change of pressure in the cylinder of a diesel engine and does not take into account of some features of the engine as in the structural and thermodynamic relations It doesn’t consider the process of combustion of fuel and air with respect to the increase of the turbulent speed of the flame front in the combustion chamber, expressed by the crankshaft angle
