Sprayers

Jets - electromagnetic type. When voltage is applied (driving pulse) to the coil of the injector needle valve of the injector opens and fuel is sprayed under pressure in the intake passage, where it mixes with the intake air into the engine. Torque control the duration of injector opening and carried ECU, which controls the nozzles on the basis of information obtained from sensors of the engine management system. The time of the driving pulse to the injector is determined by the ECU signals the crankshaft position sensor. To calculate the duration of the driving pulse control unit also uses information from the coolant temperature sensor, intake air temperature from the air flow sensor and throttle position sensor. Moreover, according to information from the sensor system or computer sends commands to all nozzles at once (simultaneous injection) or sequentially on each of them (sequential injection). Sequential injection is almost always carried out when the engine is in normal mode, and a simultaneous injection can be done when you scroll through the engine starter.
