All The Things You Need To Know About Engine Dynamometers
The most professional devices that can measure an engine’s power and torque are the engine dynamometers. They are used by the engine manufacturers themselves.
In order to perform the measurements on the engine (this is done before the engine in mounted into the chassis), the engine is connected to the dynamometer with a shaft. Afterwards, the engine is ignited, and it is set to run at a constant speed, and the torque that is applied to the dynamometer is exactly the engine’s torque. The results of these measurements are quite accurate and there are no losses because of friction.
The new-generation dynamometers are connected to computers and they are very easy to handle and operate. They can almost perfectly simulate racing and normal driving conditions.
When driving on the road, there are a few factors that may modify the way an engine acts and the power it produces. Among these there’s the air’s temperature, level of humidity and also its pressure. These can be taken into consideration when testing an engine with a dynamometer, with the help of some formulas the power...
