Akroyd Engine Lab Report
How does it work?
The Akroyd Engine uses the Otto cycle, hence consist of induction, compression, expansion and exhaustion. Starting with the piston at top dead centre (TDC), the piston moves downwards and increased the volume inside the cylinder in the process reducing the pressure. This occurs while the inlet valve is open hence a mixture of air and vaporised fuel from the hot-bulb, is drawn into the cylinder. As the piston comes to bottom dead centre (BDC) the valve closed and the piston moves back up the cylinder compressing the air/fuel mixture inside of it. As the piston approaches TDC, this compressing caused the temperature of the mixture to rise to a point where the fuel will ignite. This ignition causes and releases energy from the fuel to the gases inside of the cylinder, causing pressure forces on piston, pushing it back down the cylinder. This is the expansion stroke and this is where work is actually done on the piston, (in all other......
