I have an engine with the following specifications:
305 cc, 4-stroke single-cylinder.
Torque : 18.53 N m @ 2800 rpm.
Weight of the car 275kg
Coefficient of drag:1.15
Frontal area: 0.9177m^2
Rolling resistance:0.04482
Engine wheel efficiency: 78%

How can i calculate the Max. acceleration and Max. Power ?
 
Physics news on Phys.org
The maximum acceleration will depends on the friction coefficient of the tires. Since you didn't specify it, you cannot find it.

For the maximum power all you know is that you have 5433 W @ 2800 rpm (= 18.53 * 2800 * π / 30). Is this the rpm where you have the maximum power? No one can say from the information you gave.

I calculated A Four-Cylinder Internal Combustion Engine last year. It includes heat analysis and speed characteristics. It can help.
