Influence flame speed and flame thickness on completeness of combustion hythane

Abstract

The article is dedicated to experimental and theoretical studies characteristics of flame propagation in combustion chamber of internal combustion engine with spark ignition and their influence on completeness combustion. It is theoretically and experimentally proved that relationship of flame propagation characteristics with completeness of combustion composite fuel is complex, non-linear, and depends on chemical composition combustible mixture and temperature in combustion chamber. It was revealed that an increase thickness near-wall unburned fuel layer, size of slots in combustion chamber and surface area of combustion chamber contribute to a reduction combustion efficiency of the fuel. It is shown that an increase rate flame propagation and a decrease thickness flame front leads to an increase completeness combustion fuel. It was revealed that proposed formula, using fundamental characteristics of flame propagation, allows calculating completeness combustion composite fuel. This indicates feasibility of using this formula at the design stage and fine-tuning low-emission and energy-efficient combustion chambers of engines and power plants.
