Hey! My name is Erica. I live for one thing and one thing only - driving my car. I have always loved cars so I was super excited when I passed my driving test last year. I decided that I needed to learn everything I could about the world of automobiles so I went down to my local auto club and made some friends. The guys there were really friendly and they took the time to talk about every aspect of owning, modifying, and maintaining a vehicle. I have learnt so much over the past few months, I just had to start a new blog. Enjoy!

Is your diesel-engined vehicle costing a lot more to run than it should? Do you find that you're spending a great deal at the pump and certainly a lot more than you used to, while also noticing a loss of performance on the road? If this is driving you to distraction and you simply can't put your finger on the problem, maybe you should take the vehicle in for a special type of test to determine if there's something wrong with the engine.
On the Rollers
A dynamometer is a tool that will allow your professional mechanic to diagnose a variety of different issues related to your diesel truck or car. It is essentially a computer-powered machine that is connected to some finely balanced rollers that are sunk into the floor of the mechanic's workshop. Your vehicle will be placed so that the driving wheels are in between two opposing rollers, and it will then be tied down for safety. Once everything is ready and people are in a safe spot, the engine and transmission will be run up to maximum levels, while the vehicle is stationary in this position.
Battery of Tests
The rollers will transmit their data to the associated computer to determine how much power the engine is generating in a variety of different situations. For example, the mechanic may run the vehicle up to maximum revolutions in one gear before letting it decelerate back to normal. This sequence of tests can help them compare the vehicle's power output in relation to manufacturer estimates.
Down to Detail
There may well be a number of different issues at stake here, but the computer will make short work of this analysis. It will be able to compare your output to an extensive database of information and may point to problems with other areas, as well as simply the engine or transmission. For example, it is possible that one of the ancillaries is at fault and that this is dragging down the performance of the entire vehicle. Alternatively, it is possible that electronic sensors have failed or that filters are not performing as they should. Oxygen sensors, in particular, are very sensitive and can certainly impact your fuel performance and overall drivability.
Booking Your Spot
Contact a mechanic near you about booking your vehicle in for a dyno test. They'll need to determine if there are any obvious problems (like a slipping clutch) before they proceed, but they'll invariably provide you with a clear diagnosis, once the roller tests are over.
