Abstract: Provided is a driving evaluation device that enables evaluation of driving for the purpose of improving a driving time in a circuit racecourse. The driving evaluation device includes an evaluation section extractor 24 that detects a deceleration section and an acceleration section in cornering, a tire friction circle-load factor calculator 27 that calculates, based on a front-rear acceleration and a lateral acceleration, a tire friction circle and a tire load factor in the deceleration section and those in the acceleration section, and a skill deficiency evaluator 28 that evaluates driving based on the tire friction circle and the tire load factor in the deceleration section and those in the acceleration section.

Abstract: A control apparatus for an engine includes a rotation detector, a fuel injection device, and an output controller. The output controller calculates an emission amount of the pollutant and calculates an accumulated emission amount of a pollutant for a period of time. The output controller calculates a maximum allowable emission amount of the pollutant for a period of time. The output controller calculates a difference between the accumulated emission amount of pollutant and the maximum allowable emission amount of the pollutant. The output controller calculates a first output index by dividing the difference by the period of time. The output controller sets the allowable range for the output of the engine so that the emission amount of pollutant becomes equal to or less than the first output index.
