Dear kafi Research ki jaisa k ap janty ho..................
Cultus Euro 2 Engine Specs
Engine type G10B (SOHC)
Cylinders 4
Bore 72.0mm
Stroke 61,0 mm
Compression ratio 9,5.1
New Celerio AKA Cultus
Engine type K10B (DOHC)
Cylinders 3
Bore 73.0 mm
Stroke 79.5 mm
Compression ratio 10.0.1
Big bore = more valve curtain area / higher breathing capacity
here's the short version...
a SOHC or single overhead camshaft engine uses a single camshaft on the head to lift all the valves, whereas in a DOHC or double overhead camshaft head, two camshafts are used to lift the valves (a camshaft each for intake and exhaust valves) ;
a DOHC layout is better than a SOHC layout in many ways- in DOHCs, the valve timing is more precise, and better valve lift is achieved. also, a DOHC setup eliminates the need for rocker arms, hence creating better timing, and valve contact is more direct too. but of course, these are all in stock form. a SOHC layout, when tuned, can be as efficient as a DOHC, but under proper tuning, DOHCs always achieve more power than SOHCs...
Kindly agar koi mistake ho to meray ILM mai izafa kigiyea
