Analysis: Anderson explain the F1 Engine mapping

BBC’s F1 technical analyst Gary Anderson explained about the Formula 1 Engine mapping.

Anderson explain the F1 Engine mapping: “To fix the loophole, the FIA could write a rule that said: “The accelerator pedal travel will be defined as 0% (minimum) to 100% (maximum) and at any position between these two end stops the percentage torque output of the engine base torque map for the measured engine speed must match the accelerator pedal percentage +/- 1%…

“This would mean the relationship between throttle pedal position and the torque delivery must be linear.

“And the rule could finish by saying: “… and the percentage of throttle body opening must match the accelerator pedal percentage +/- 10%.

“That would mean any change in torque characteristics could not be done by just retarding the ignition – a common method of employing engine braking – while leaving the throttle open to pump air through the engine and exhausts, which is a way of using the exhausts for aerodynamic effect.

“Allowing a margin of +/- 10% provides some leeway for the characteristics of different engines, as all have different operating requirements.”
