As a mechanical project we have been asked to design a micro steam car

    as a mechanical project we have been asked to design a micro steam car. we have chosen to use a wobbler engine for this. The aim of the project to see how far this car can travel based on a given amount of fuel. We are making a boiler which will provide the steam to run the piston but we have no idea on how to calculate the sizing of the piston. We are assuming the pressure in the boiler will be at 2 bar. how do I calculate the piston sizing ?

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    Calculate, or if you have enough of the chassis built measure, the force needed to get started, from the diameter of the wheels calculate the torque required, from the distance of the con rod to the wheel centre calculate the force required on the con rod, from that value calculate the piston diameter.
