The goal of this project is to build a new model of two-stroke spark-ignition engine in order to decrease scavenging issues.
This style permits fresh air to enter the cylinder through intake valves at the bottom and burned gases to depart through exhaust ports at the top.
As the piston pulls towards the bottom of the cylinder, the exhaust ports close, and the fuel is pumped.
As a result, the chances of fuel and exhaust gases combining are reduced. Due to pressure differences and high temperatures, the exhaust ports unravel during piston expansion, allowing the burnt gases to escape into the atmosphere.The exhaust gases accelerated in the opposite direction of gravity, reducing the possibility of entering fresh air being combined. The engines were created and built using a two-stroke engine's existing ports as well as a reasonably simple valve train system. This project is about the air flow design of a two-stroke engine with fuel injection. Short circuiting and mixed scavenging concerns are avoided with this approach. Furthermore, when fuel is injected against gravity rather than with gravity, the dispersion is larger, resulting in cleaner burning. This research looked at the emission characteristics of enriched fuel in a modified air flow engine and discovered that improved combustion resulted in lower greenhouse gas emissions and lower fuel consumption. With a 2 stroke and 4 stroke engine, the characteristics of engine performance and emission of a dual fuel mode engine are compared and examined. The optimised result is done with Diesel-RK software, and flow analysis is done using ANSYS FLUENT, according to the experimental analysis.
