A Quasi One-dimensional Simulation of a 4 Stroke Spark Ignition Hydrogen Fuelled Engine

Abstract

Active research and development on hydrogen-fuelled engine had been done for few decades since hydrogen serves as a potential of infinite fuel supply. This paper discussed analytically and provides data on effects of compression ratio, equivalence ratio and spark timing of a hydrogenfuelled engine as a guideline for the engine design. The change in thermodynamic properties of the fuel was considered through the engine cycle. A modified version of Olikara and Borman method was presented to track the mole fraction of the equilibrium state of combustion products for hydrogen fuel.The equilibrium values of each species were used to predict the NO x formation, which is the main concern of study for hydrogen-fuelled engine.

Transient in-Cylinder Gas Flow Characteristics of Single Cylinder Port Injection Hydrogen Fueled Engine

“…Residue and pollution by emissions were produced by the growing number of vehicles on the road day by day increases. Hydrogen is particularly suitable for fueling internal combustion engines (Yusaf et al, 2005). The flow field identification inside a cylinder of the internal combustion engines during the intake, compression, expansion and exhaust strokes are an important stage for the comprehension of physical phenomenon which occurs in the motor cycle.…”
