Design and analysis of fuel intake system for biogas operated spark ignition engine

Improving the biogas engine performance by implementing the pressurised turbulent flow is discussed in this paper. The pressurised flow will increase volume of the fuel; hence improve the volumetric efficiency and the turbulence will increase the homogeneity of mixture; hence improve the flame speed. It is also known that the inlet port design and the intake manifold configuration have a direct influence on engine performance and emissions. Based on this fact, the intake process may give a great contribution towards increasing the Biogas engine performance; the paper focuses on the design and analysis of the fuel intake system as economical devices without major modification. It includes analytical design of an intake system for biogas operated single cylinder 4-S spark ignition engine.
