the Horse Power is the power produced by an engine which depends upon the Torque and RPM of the engine. P=(2*pi*N*T)/60 where N and T are RPM and Torque respectively. and so P is dependent upon the N and T and is directly proportional to N and T.
But same 150cc Engine and only variation is air cooled and oil cooled and oil cooled engine gives more power compare to Air cooled? For Example: Yamaha FZ 150cc and power around 13.5 BHP air cooled and Yamaha R15 150cc and power around 17 BHP oil cooled. What is the key factor?
hello sir u said higher the cc less will be the mileage but for royal enfield TAURUS/DIESEL model it has 325 CC engine and it gives around 50 - 60 kmpl can u explain concept
Power increases, Torque will reduce. Normally in high rpm power will be higher and low rpm torque will be higher. That is the reason when climb up hill we need more Torque rather than power and we ride bike with 2nd and 3rd gear.
Also Torque = Force * Displacement. In bullet stroke length is higher compare to bore. So high stroke length will give more torque and this will be controlled by crankshat eccentric ( From crankpin dia center to main shaft center. For example Eccentric distance is 33mm then stroke length is 66).
