A camshaft pushes against valves in your engine that allow air and fuel in, and exhaust out. This is important, otherwise the valves would not work as well and exhaust would build up, and it would be difficult to allow air and fuel in.
Yes you can but the engine performance will drop and it may be noisy.
A PH15 is a type of aftermarket performance camshaft that can enhance the engine's performance, while a D15B is a specific engine model from Honda. While a PH15 camshaft can improve the output of a D15B engine by optimizing valve timing, it doesn't directly "equalize" the power of the engine. The overall performance will also depend on other factors such as fuel delivery, exhaust, and tuning. Therefore, while the PH15 can boost power, it doesn't equate to the engine's power output on its own.
Depending on the context, "degrade" could be. The engine's performance had been improved. The engine's performance was degraded.
Yes. The camshaft determines valve lift, duration and timing. By changing those specifications the engine performance can be significantly modified.
It is a variable valve timing innovations from toyota, where in power and fuel efficiency can be optimized by varying the timing of the camshaft with respect to the crankshaft of an engine,by retarding or advancing the camshaft by a certain phase angles.A conventional engine has it's camshaft rotate half the crankshaft rotation and the performance of a such engine would be in it's peak efficiency for a single speed only.Engineers developed a technology to overcome this in-efficiencies by introducing variable valve timing where camshaft rotation can advance or retard with respect to the crankshaft,hence optimising performance and fuel efficiency.
Exhaust camshaft phasing on a VVT (variable valve timing) engine is the adjustment of the exhaust camshaft(valve timing) to what the cylinder needs at that rpm/load to improve power/eff. or emissions.

The camshaft operates the valves on a 4 cycle engine.
With proper maintenance, the camshaft should last the life of the engine.

A two-stroke engine does not have a cam or camshaft. Seeing there is no intake/exhaust valves it would be pointless to have a camshaft.
There is no camshaft in a 2-cycle engine.
