Im trying to build up my own car, I just have some issues with stability. I am trying to build a 1.8L TDCi, 0-60mph is around 5.67sec and 50-70mph is 5.4 secs. However, it has bad fuel economy and top speed performance.
anyway thanks
I have estimated a gear ratios for this design.
I have different RPM's of the car and I have calculated they're corresponding speed at each gear at each RPM. And I also have calculated the road load at each gear and at each RPM.
I need to find the torque I have the running resistance...
I have a car engine specs and I wanted to estimate the torque at each speed and plot the torque curve.
I have calculated the road load or the running resistance force for all gears at different RPM's and found the speed (m/s) for each RPM.
How to estimate the torque of the engine in order...
