It's supposed to compensate idle for added load, most all cars do that when ac is on as well ECU adds about 50 rpm to prevent stalling.

What is the increase decrease screw on the engine on your timberwolf atv?

The increase/decrease screw on the Timberwolf ATV engine is used to adjust the idle speed of the engine. Turning the screw clockwise will increase the idle speed, while turning it counterclockwise will decrease the idle speed. It is important to adjust this screw carefully to ensure the engine runs smoothly.


Why does your RPM increase when your car is in Park?

AnswerThe RPM is related to the load on the motor. When you have the Transmission engaged it puts a load on the motor. When it is in park, it does not put a load on the motor. That allows the RPM to increase. AnswerThe computers in some cars are programmed to increase the engine speed when certain accessories are turned on, i.e. when the air conditioner clutch engages. This ensures that the engine does not stall with the added load, and that the engine maintains a high enough speed to keep the alternator generating adequate current to maintain system voltage. If the increase in RPM is happening just as you put the transmission into Park, it is because the transmission is no longer putting a load on the engine.Turning off high current accessories can also cause the engine speed to increase slightly.

How do you increase rocket speed?

To increase rocket speed, you can add more propellant to increase thrust, reduce the rocket's mass by shedding unnecessary weight, or improve aerodynamics to minimize drag. Additionally, optimizing the rocket's trajectory and using efficient engine designs can also help increase speed.

What causes hunting on an x reg focus 1.8 petrol engine?

If you mean hunting at idle, the problem is caused by the idle speed being set too high or the idle switch is not properly adjusted. When the throttle is closed as indicated by the idle switch the fuel is cut off by the fuel cut solenoid until the engine speed drops below a preset speed. If the engine speed is higher than that speed and the idle switch is closed there is no fuel for the engine, thus the engine speed drops. When it drops below the preset speed the fuel is turned on and the engine speed goes back up.


How is the speed of a piston is determined?

The speed of a piston in an engine is determined by the engine's RPM (revolutions per minute) and the stroke length of the piston. The speed can be calculated using the formula: speed = (2 * pi * RPM * stroke length) / 60. Increasing the RPM or stroke length will increase the speed of the piston.
