Answer 1

1. string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. It describes how these strings propagate through space and interact with each other.

2. the ideal burn time of the ignition wave form of a new vehicle is 1.5 ms to 2.5 ms.

3.High spark Kv means higher than normal resistance.COP is here to stay until vehicles become all like diesels and ignite using compression. Because COPs do not use plug wires, this reduces the amount of ignition parts and makes them better suited for high kilovolts (KV) demand during high engine loads.

4.lower spark Kv means lower than normal resistance. Tensions in the secondary circuit of ignition during the combustion of spark are usually between 1 kV-2 kV.

6.A leaking injector will cause the burn line to go down beacuse the rate of combustion decreases due to leaking .

7.current ramping ignition coil primary not only opens up a whole new world of diagnostics, it can also help to understand how ignition coil really work.

8.Types of spark plug are Electric spark plug , Reading spark plug, Indexing spark plug .

9.Once the wire is removed, you can use your socket wrench with the spark plug socket to remove the seated spark plug. Fit the socket around the spark plug and turn the wrench counter clockwise. If the cylinder is at an odd angle, use a universal joint to reach it. The spark plug should unscrew easily.
