The request to mean: measurement of engine capacity and running indicators is made on the terms of the relevant standards of DIN (on serially equipped cars). Tolerances are also standardized. The additional equipment sometimes strongly influences running indicators and fuel consumption since the weight and coefficient of an obtekayemost changes (a luggage carrier on a roof, wide tires, additional mirrors etc.).
