Ch 4 – Engine Basics

Technician A says that horsepower is the ability to maintain a load a desirable or fixed speed and is a measure of how fast wok can be done. Technician B says that torque is a rotational or twisting force around a fixed point, and that the longer the crank and the slower the rotational speed, the greater the amount of torque generated. Who is right?
 
Technician A says that the crankshaft in a two-cycle engine will make two revolutions during each complete combustion cycle, while the camshaft will make only one. Technician B says this is true of four-cycle engine, not two-cycle engines and that in a two-cycle engine both the camshaft and the crankshaft turn at the same speed. Who is right?
Technician A says that a supercharger is driven off of the engine while a turbocharger is driven by exhaust gases. Technician B says that superchargers are more efficient than turbochargers because they work hardest when engine speeds are higher and do not draw power from the engine operation. Who is right?
