What is meant by oval pistons and elliptical pistons?
OVAL PISTONS- Oval pistons are first introduced by HONDA in their model NR 500 as they were forced to develop a engine to deliver high power output in motogp as number of cylinders were redtricted to 4 in that time.
Oval piston is not exactly oval but it nearly looks likw it with astonishing 8 valves per cylinder, two connecting rods per cylinder,higher output to increased air fuel mixture.It will be usually used in V4 and v8 emgines with 90degree apart.
Advantages :
*High power output
*Increased torque
Disadvantage
*problem araised because there is no proper and efficient piston ring available for oval pistons.
*high cost
*high skilled technicians required
I know that it wad banned from MotoGp but why?
Why it was not commercially success?
Do you know about elliptical pistons?
if possible explian the working in a simple manner so that we can carry on the topic.
