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

In summary, the conversation involves a mechanical project to design a micro steam car using a wobbler engine. The goal is to determine how far the car can travel on a given amount of fuel. The project team is facing difficulty in calculating the sizing of the piston for their boiler, assuming a pressure of 2 bar. The solution involves calculating the force needed to start the car, the torque required based on wheel diameter, the force on the con rod based on distance, and then using these values to calculate the piston diameter.

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 ?

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.
 

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

1. What is a micro steam car?

A micro steam car is a small vehicle that runs on steam power. It is typically designed to be more energy-efficient and environmentally friendly than traditional gasoline-powered cars.

2. How does a micro steam car work?

A micro steam car uses a small boiler to heat water and produce steam. The steam then powers a small engine, which turns the wheels and propels the car forward.

3. What are the benefits of a micro steam car?

Some potential benefits of a micro steam car include reduced emissions, improved fuel efficiency, and the use of a renewable energy source. It may also be more cost-effective in the long run, as steam is a cheaper fuel compared to gasoline.

4. What are the challenges in designing a micro steam car?

Designing a micro steam car can be challenging due to the small size and limited space available for the necessary components, such as the boiler and engine. Additionally, ensuring the safety and reliability of the car while also maximizing its efficiency can be a complex task.

5. Are there any existing micro steam cars on the market?

While there are some prototypes and concept cars, there are currently no mass-produced micro steam cars available for purchase. However, there is ongoing research and development in this area, and it is possible that micro steam cars may become more widely available in the future.
