Witryna13 kwi 2024 · If the coil was triggered to fire once every revolution, it would hit one cylinder right before TDC of its power stroke and the other at the tail end of the exhaust stroke. Hitting the spark plug toward the end of the exhaust stroke has no significant effect upon combustion because most of that already happened earlier in the cycle.

Witryna7 lip 2024 · An internal-combustion engine goes through four strokes: intake, compression, combustion (power), and exhaust. Which event occurs when the piston reaches TDC of the compression stroke group of answer choices? The piston reaches TDC. As the piston reaches TDC, the air/fuel mixture burns, increasing the pressure … WitrynaThe compression stroke is the second of the four stages in a four-stroke engine. In this stage, the air-fuel mixture (or air alone, in the case of a direct injection engine) is compressed to the top of the cylinder by the piston. This is the result of the piston moving upwards, reducing the volume of the chamber.
