The ________ is used to determine if each cylinder is contributing power to the overall engine output.
A) four gas analysis
B) snap throttle test
C) vacuum test
D) power balance test
Power Balance Test
A test used to determine if each cylinder is contributing power to overall engine output. During the test, fuel injectors are disabled and the change in engine rpm is recorded. If a cylinder is not producing power, there will not be an rpm drop when that cylinder’s injector is disabled, alerting you to the problem cylinder.
Engine Output
The amount of power produced by an engine, typically measured in horsepower or kilowatts.
- Identify the distinct types of engine diagnostic tests and their unique applications.
- Interpret the results of engine diagnostic tests to determine the engine’s condition.

Final Answer :
D
Explanation :
The power balance test is specifically designed to assess whether each cylinder in an engine is contributing equally to the engine's overall power output. By comparing the power output of each cylinder, mechanics can identify any cylinders that are underperforming.
