Slip ratio is calculated by dividing the difference between the actual speed of a wheel and the speed of the vehicle by the speed of the vehicle.

• Calculate the actual speed of the wheel by multiplying the wheel radius with the angular velocity of the wheel.

• Calculate the speed of the vehicle using GPS or speedometer readings.

• Subtract the actual speed of the wheel from the speed of the vehicle.

• Divide the difference by the speed of the vehicle to get the slip ratio.

Plotting graphs of engine out emissions vs lambda is essential for analyzing the relationship between emissions and air-fuel ratio.

• Lambda values represent the air-fuel ratio in an engine, with stoichiometric ratio at 1.0.

• Engine out emissions include pollutants like CO, HC, and NOx.

• Graphs can help identify optimal lambda values for minimizing emissions.

• Example: Higher lambda values (lean mixtures) can reduce CO emissions but increase NOx emissions.

• Example: Lower lambda values ...read more
