Is there a posibility to develop twin engine 200CC motorcycle which is priced Rs 70,000 with good fuel average

Answer 1

THERE IS NOTHING THAT CAN'T BE DEVELOPED WHITH ENOUGH TIME, MONEY, AND INGENUITY. YOU MIGHT TAKE A COUPLE OF 90CC MOTORS, BORE THEM OUT SLIGHTLY TO 100CC EACH AND MOUNT THEM. DON'T FORGET TO PUT IN A GOVERNOR TO KEEP MOTORS IN SYNCH. ANOTHER OPTION WOULD BE TO TAKE A 400CC V-TWIN TYPE MOTOR, AND SLEEVE THE CYLINDERS DOWN. ADD TWO 90CC PISTONS WITH OVERSIZED RINGS. GOOD LUCK.

Answer 2

If you have the proper tooling facility, it is possible to construct a 200cc bike engine from parts available from the bike spares shops.
You will need 2 of most engine components such as crank shaft, crankcase, cylinder, piston, cylinder-head etc.
You got a choice of configurations:
1. 180 deg. twin
2. 360 deg twin
The second is easier to construct as both pistons are fixed in parallel. That is why its also called a parallel twin.
The arrangement of the valve assembly is also simplified because both pistons are working at opposite strokes.
So, if inlet valve of cylinder A is just opening, the exhaust valve of cylinder B would be just opening. And vice versa.
The ignition spark can be fed from a single coil, with split cable to feed both cylinders.
When cylinder A gets a spark at combustion point, cylinder B too will get a spark, but nearly at the end of the exhaust stroke.
It is the same vice versa.
So the setting of the ignition timing is simple, as one setting is enough for both cylinders.
Only one timing chain to the camshaft is required.
An existing clutch and gear assembly would suffice.
The complications are:
Joining the two crankshafts,
Making a single crankcase,to seat the crankshaft.
Making a single camshaft out two.
Reworking a oil lubrication system to supply oil to both cylinder heads.
Mileage will not be a problem.
A parallel twin will have a power stroke for every rotation of the engine, and will therefore be having very good torque.
You will need lesser gear changes which should increase the mileage.
But in top gear, you should be willing for some drop in mileage when compared to a 100cc single cylinder as the extra power of the 200cc twin may not be fully utilised.

Answer 3

Keep track of the technological revolution taking place in the two wheeler world. Give your idea to a Good manufacturer. Who knows ? They might just take up your challenge!

Answer 4

NO BCOZ CC IS INVERSELY PROPORTIONAL TO AVERAGE
