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!
