Can torque converter make noise?
Your torque converter can make a variety of noises when it goes bad. You may first notice a whine, similar to a power-steering pump that is low on fluid. The stator within the assembly uses an overrun mechanism with a series of clutches that, when bad, can cause a rattling noise.
How do you measure the torque?
The formula for figuring out torque is torque = horsepower of the engine x 5252, which is then divided by the RPMs. The problem with torque, however, is that it is measured in two different places: directly from the engine and to the drive wheels.
Why do we measure torque?
Why do we need torque measurement? Torque is applied to a joint, e.g. a nut & bolt, to apply the correct level of tension which holds an assembly together. The correct level of applied torque is critical to all joints. Too much tension and a bolt can become warped and fracture.
What is the possible reasons for error in torque measurement?
During measurement experiment, the errors generated from mechanical installation, bearing friction and electrical machine driver nonlinearity are likely to be converted into the torque measurement results, which leads to torque measurement errors and decreases the measurement precision.
Is used to measure torque?
Direct method. The torque signal is determined through direct torque measurement in the drive train. Normally, torque flanges are used for contactless measurement, for example, the T12 digital torque transducer or T40B from HBM.
How do you measure torque when tightening?
Measuring method Loosen the bolt using a torque wrench and read the torque when the bolt starts moving. T i g h t e n t h e bolt further to determine the applied torque. Read the torque when the bolt starts moving again.
What is used in measuring torque?
Torque is a measure of rotational or “twisting” force. Measuring torque while installing a bolt prevents the overtightening of bolts. Torque wrenches are the most commonly used measures for this torque. They measure the torque applied to the fastener as the wrench tightens the bolt.
How is motor torque measured?
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
What kind of sensors you can use to measure torque?
There are two main categories of Torsions Sensors: rotary torque sensor and reaction torque sensors. In summary, a reaction sensor measures stationary torque (static or non-rotational), and rotary measures rotational torque (dynamic torque sensor).
How to find the source of engine noise?
Pay attention to the engine sounds. Rev the engine a couple of times. If the noise is not present, most likely the belt or one of the accessories is the source of the noise. You can use a timing light to help you locate the source of engine noise.
Why does engine noise increase with engine speed?
If the noise doesn’t increase with engine speed, it’s probably not an engine noise. If the noise increases with engine speed, most likely the noise is coming from the engine, though if you have an automatic transmission it might come from the torque converter.
How to diagnose engine noise using ear tools?
Start the engine, set the parking brake, and set the transmission to Neutral (manual) or Park (automatic). Open the hood. Using the stethoscope or one of the other tools, move the tip around the valve cover and cylinder head, being careful with moving components.
What to do if your car engine is making noise?
Spray some belt dressing on to the belt. If the noise goes away, the belt is the source of the noise. Another way to check for belt or accessory noise is to remove the suspected belt. Remove the drive belt or serpentine belt from the engine. Rotate by hand each of the accessory pulleys the belt runs on.
