Fuel is sprayed by a nozzle in an inlet pipe where mixes up with air and via the valve gets to the cylinder. The engines equipped with system of injection in comparison with carburetors have the following advantages:

exact dosage of fuel at various operational modes, smaller fuel consumption on the maximum capacities;

reduction of quantity of harmful substances in exhaust gases;

possibility of additional purification of exhaust gases adjustable catalyst;

self-diagnostics of knots of system of injection;

cистемы of injection of fuel do not demand leaving, replacement of the fuel filter through 20 000 km and the air filter through 30 000 km, and at cars is carried out from 9.88 only. – through 60 000 km.
