B. 720 degrees.
In a 4-stroke engine, one complete engine cycle consists of four strokes: intake, compression, power, and exhaust. This cycle requires two full rotations of the crankshaft, which equals 720 degrees of crankshaft rotation. Each stroke corresponds to 180 degrees of crankshaft movement, collectively completing the cycle.
In a four-stroke engine, it takes 720 degrees of crankshaft rotation to complete one full engine cycle, as the cycle consists of four strokes: intake, compression, power, and exhaust. Each stroke corresponds to 180 degrees of rotation. In contrast, a two-stroke engine completes a cycle in just 360 degrees of crankshaft rotation, encompassing both the power and exhaust strokes in a single revolution.
The crankshaft makes two complete revolutions to complete one thermodynamic cycle. The crankshaft rotates 180 degrees during each stroke of the engine. Hence a total of two revolutions occur after completion of the four strokes. Chechout "www.howstuffworks.com " to see how crankshaft works.
180 degrees
180 degrees is 1/2 of a complete turn
In a 4-stroke cycle engine, two complete revolutions of the crankshaft are required to complete one cycle, which includes intake, compression, power, and exhaust strokes. Therefore, for each individual stroke (intake, compression, power, or exhaust), one rotation of the crankshaft corresponds to half of that duration. Thus, one stroke occurs for every 180 degrees of crankshaft rotation.
The complete arc of a semicircle is 180 degrees
One cycle of the sine wave is equal to 360 degrees. In US the frequency of power is typically 60 Hz and hence one cycle is 1/60 of a second. Therefore you can calculate the degrees at any instant of time. If at zero degrees the voltage amplitude is zero, then at 90 degrees,which is 1/4 cycle, wave is at peak voltage. At 180 degrees it is at 1/2 cycle and zero voltage and then at 270 degrees it is 3/4 of the cycle and a peak negative voltage. Finally at 360 degrees the cycle is complete and the voltage is again zero.
Typically, the piston can move 180 degrees in an engine's stroke cycle, while the crankshaft rotates 360 degrees for every cycle. The cylinder head does not have a specified degree measurement as it is stationary and houses the valves, spark plugs, and other engine components.
Distributor was removed and put back in the wrong position throwing the engines timing off by 180 degrees.
Assuming we are talking about the distributor, no it won't start unless you also move the wires on the cap 180 degrees.
An angle with a measure of 180 degrees will look like a straight line with the vertex being a point in the center. Since a complete circle is 360 degrees, opening an angle to 180 degrees traces out exactly half a circle.
