Which is best 2-stroke or 4 stroke?
Two-Stroke vs Four-Stroke
| Two Strokes | Four Stroke |
|---|---|
| It generates high torque | It generates less torque |
| Its uses port for fuel’s outlet and inlet | It uses valves for outlet and inlet of a fuel |
| Its engines result in lesser thermal efficiency | Its engines result in higher thermal efficiency |
Why is the cam sprocket twice as big as the crank?
Because the cycle takes two revolutions, the camshaft runs at half-crank speed and the cam sprocket is twice as large as the crank sprocket. Match the cam’s lift and duration to combustion chamber capacity, head port size, exhaust system design, and other aspects of the engine.
How many teeth are on a camshaft sprocket?
One tooth on the camshaft sprocket represents 40 o on the crank, and one tooth on the intermediate gear in relation to the half time pinion equals 15 o on the crank.
How is the camshaft connected to the crankshaft?
The camshaft is connected via the timing chain and sprockets at a 1:2 ratio to the crankshaft and therefore revolves once for every two turns of the crank. Its purpose is to operate the intake and exhaust valves in the correct timing with the piston as it sequences thru the four strokes.
What’s the difference between race cam and Street Cam?
Street cams have low overlaps and race cams have high overlaps. After a manufacturer grinds a cam, there is only one specifi cation that you can change, the installed cam centerline. This is the relationship of the cam to the crankshaft, sometimes called the intake centerline.
How many teeth on the camshaft sprockets?
The camshaft sprocket has 42 teeth, which means that for 90 degrees of rotation there are 10.5 teeth. This also means that if the other two holes are used to mount the sprocket the relative position of the sprocket to the cam is offset by 0.5 of a tooth (Figure 1).
Can the sprocket on the camshaft spin?
Some people report the camshaft sprocket spinning on the camshaft. This results in a loss of valve-piston timing and bent valves/damaged heads . The effect is very similar to a timing belt losing teeth and slipping.
What is a cam sprocket?
A cam sprocket is attached to a camshaft in a combustible engine to help maintain timing.
What are camshaft gears?
The camshaft gear is a car part which can be found inside the garage at home. It is attached to the camshaft with 1x10mm bolt. Alignment. The camshaft must be aligned properly before fitting the timing chain.
