Abstract The article contains results of the analytical research tractionspeed performance of the automobile with the standard carburettor feed system and a distributed electronic petrol injection type LHMotronic with feedback system and waste gases neutralization system. The dynamic factor D at maximum speed (Vmax= 22,749 m/s) determines the resistance coefficient of the road ψv, which for automobile with petrol injection is ψv = 0,074, which on 6% more than at the engine carburettor system. The maximum dynamic factor Dmax, which is corresponded to the highest road resistance and characterized by a factor ψmax. Overcoming road by automobile for uniform motion in first gear with injection where ψmax= 0,377, and the carburettor ψmax = 0,36, which is 5% less than with injection system petrol. Acceleration of automobile in every gear at the given road conditions (ψ = 0,02) increase by 6% with petrol injection. Acceleration to Vmax= 22,749 m/s (nd = 3200 min1) with the injection system continues to τ = 22,43 seconds. The distance travelled by the vehicle during this time is S = 303,07 m, respectively, decreased by 6% than with the carburetor system. The research is indicated that replacement by carburettor system for the help of system type LHMotronic improves tractionspeed characteristics of the automobile.
