Renault F1 Engine on the dyno

Would have liked to see this in more detail, but still pretty cool.

Notes on the video

The RS27 engine on the dyno at Viry-Châtillon, France, for the last endurance test before the beginning of the 2011 season. Four hours of work summarized in one minute...

To make sure the engine is able to cope with the trials presented over several GPs, engineers and technicians at Renault Sport F1 put it through a series of tests in which the acceleration, braking and speed changes encountered in a real race are simulated.

In the video, the RS27-2011 is prepared to run through a simulation of Fernando Alonso's qualifying laps at Monza in 2009. The main aim is to understand how the engine behaves in such a demanding situation.

To reproduce the conditions of a race, the engine is set up on a transmission line and is fed with oil, water, electricity, air and fuel. Data is also transmitted to the engine to recreate driver input through the steering wheel, such as changing gears, fuel/air ratio modifications and so on.
Pressured air is also blown into the engine to simulate the air intake of the car on-track.

The dyno is designed to ensure all parameters of the RS27 engine can be run to their most extreme limits (up to 18 000 RPM). Pressures, top speed, RPM and exhaust gas composition are all monitored, along with several other key systems.

The tests take place in a cell with cutting edge sound proofing, on a floor designed to reduce vibrations. Heat has to be extracted from the cell during the test, as the air can reach up to 900°C!

nice finds mate

those hot mani's remind me of this pic....

 

[DrDrew]

Nice. Found this one too, and it looks like it was only a spyker/midland

hahaha love it :mrgreen: :mrgreen:

also love the way everyone in the room is holding there ears apart from the team guys right nxt to it who just has his arms folded and a big grin on his face :lol: :lol:

Sowwy!

I love the colour of the exhaust manifold on the bench dyno. Reminds you of how hot things get.

Looking good !

All of them are good, But i think this just a big middle finger to all other F1 engines ... And we have renault to thank for it too XD

Now, who needs synthesizer?

 

[ClioSXT]

Now, who needs synthesizer?

Haha, Ive never come across a sample pack that is a f1 car engine ... could be something to look into XD

I was looking into how they have done this and it is using a form of synthesiser

It uses a basic single line MIDI track. and a sample bank of the F1 engine Being revved though out the entire rev range. this is connected to to a Sonograph to work out what RPM relates to what frequency.

From that info they can then work out how to get certain notes from the engine as they now now how much rpm is needed to give any note.

incredible throttle control is needed to do this.

In theory. any song is playable simply by uploading a new midi track into the ecu. Even songs as complex as queens Bohemian rhapsody !!

Impressive stuff to be able to control engines RPM to such a fine amount. even if it is only for a form of entertainment !

Lotus do it as their "party piece" now they did it at Goowood.
