Engine power balance Function Description:<\/strong>
\nDuring the power stroke of each cylinder, the power balance monitors the crankshaft acceleration to determine the relative power provided by each cylinder. The crankshaft acceleration data obtained from each power stroke is saved according to the ignition order, and the calculated results show the difference of each cylinder in a graphical form.<\/p>\n

If the engine jitters at idling speed, this function can be used to see which cylinder has different input power from other cylinders, so that targeted maintenance can be carried out.<\/p>\n

There are a couple of different ways you can go about canceling cylinders. The easiest way is with a scan tool. Some tools have built in the capacity to\u00a0do a power balance test\u00a0this way, Launch scanners obtain the crankshaft acceleration data from each power stroke and save them in the order of ignition, then calculate result shows the difference of each cylinder in a graphical form.\u00a0The Launch scanners that are tested able to monitor Engine Power Balance are X431 PAD VII \/ X431 PAD V, European Euro Tab III, MM4.0\u00a0(Other devices can buy \u201cEngine Power Balance Monitoring\u201d function in Mall module). And the workable vehicle makes are\u00a0Hyundai, Kia, GM, Chrysler, Nissan, Infiniti, Honda, Acura, Ford.<\/p>\n

Why need to test\u00a0Engine Power Balance?<\/strong>
\nA power balance test locates the cylinder causing a lack of power and not contributing to the engine\u2019s balance and performance. The cause of unequal power balance can mean a problem in the cylinders themselves, as well as in the piston rings, valve train, head gasket, fuel system, or even the ignition system.
\nSo if you have misfire codes or if you have a rough-running engine, this is a good place to start your diagnosis. No matter how many cylinders you have in your engine, each cylinder is designed to produce the same amount of power. When one or more cylinders aren\u2019t producing their proper power output, you may have a misfire and also a loss of power. One way you find the offending cylinder(s) is by doing a power balance test. While the engine is running, you cancel each cylinder one at a time and look for a drop in RPM. Each cylinder should produce the same RPM drop. If you get to a cylinder and there is no RPM drop, you\u2019ve found a bad cylinder. Once you\u2019ve found a bad cylinder, focus your diagnosis there to find the source of the issue.<\/p>\n

How to\u00a0test\u00a0Engine Power Balance\u00a0using\u00a0Launch scanner?<\/strong>
\nTake Ford as an example and it is applied to other car makes.<\/p>\n

1.Enter \u201cEngine Power Balance Monitoring\u201d, Select \u201cFORD\u201d.<\/p>\n

\"\"<\/a>

\"\"<\/a><\/p>\n

7.Read power balance warning info carefully, that:
\nEnsure that the parking brake is engaged and the wheels are blocked at the front and rear of the vehicle. Excessive RPM or rapid RPM changes may cause data missing.
\nPlacing the transmission in gear and maintaining a steady load may help identify the suspect cylinders. Use reverses so that the parking brake is not automatically disengaged.
\nStart engine and then press \u201cOK\u201d.<\/p>\n
