A 4 cylinder car has 4 Pistons(adsbygoogle = window.adsbygoogle || []).push({});

The cycle is

1-2 : Adiabatic compression of air

- then injects fuel

2-3 : Burn Fuel

3-4 : Adiabatic expansion of gas

4-1 : Exchaust / Replace with fresh air

1. The problem statement, all variables and given/known data

Diameter = 10 cm

Minimum depth 1 cm

Maximum depth 10 cm

Heating value of fuel is 2,100 j/g

Each cycle uses 0.005g of fuel

Temp of air = 25 degree celcius

Pressure of air = 101 325 Pa

2. Relevant equations

Draw P-V Diagram

Calculate P,T,V at all points (1,2,3,4)

Calculate power produced by car at 100 RPM , 500 RPM and 1000 RPM

3. The attempt at a solution
