The most qualified devices that can measure an engine's energy and torque are the engine dynamometers. They are used by the engine companies themselves. In order to execute the measurements on the engine (this is accomplished 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 precisely the engine's torque. If you know any thing, you will probably claim to read about  [http://chryslersebringpcm.com/chrysler/cat_1.html pcm for chrysler sebring] . The benefits of these measurements are fairly precise and there are no losses due to the fact of friction. The new-generation dynamometers are connected to computers and they are extremely straightforward to handle and operate. They can almost completely simulate racing and regular driving circumstances. When driving on the road, there are a handful of variables that could modify the way an engine acts and the power it creates. This pictorial  [http://chryslersebringpcm.com/ chrysler sebring pcm]  article directory has a pile of forceful tips for when to see it. Amongst these there is 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 aid of some formulas the energy that an engine can give can be calculated under several sorts of meteorological situations, so how the power modifies when the air pressure drops for instance can be effortlessly calculated. True-life circumstances can be simulated by increasing the temperature at which the dynamometer tests are performed, because the engine is heating up as it runs. Anyway, it mustn't be forgotten that when the engine is installed into the chassis it will connect to the drivetrain, and this plus a few far more items will make an critical element of the energy to be absorbed, so the readings from an engine dynamometer will be a little diverse.

To measure the power of the dynamometer 'at the wheels' a chassis dynamometer is needed.
