Abstract
The utility model discloses a monoblock pump system kerosene motor, and the kerosene motor is provided with an electric control monoblock pump unit and an electronic control system. The electric control system comprises an electric control unit (ECU) arranged under the electric control monoblock pump unit and a plurality of sensors. The electric control unit (ECU) is connected with the sensors and the electric control monoblock pump unit via conductor bundles. The utility model can ensure that the air-fuel delivery ratio of the motor is in optimum state, to control the fuel jet and make the ignition mixture gases burnt completely, thereby keeping the motor working in the best combustion and discharge effects to reduce the hazardous substances in the exhaust emissions resulted from the engine combustion.
Description
Technical field
The utility model relates to a kind of technical field of diesel engine, especially relates to a kind of automatically controlled unit-pump system diesel engine.
Background technique
At present diesel engine is on the vehicle, especially obtained using widely on the load-carrying vehicle, but reason owing to its structural characteristics of diesel engine and the composition of diesel oil own, contain a large amount of discharge of poisonous waste in air in the effulent after its burning, not only had a strong impact on environment, and people's health has also been caused great infringement.In order to improve this situation, people formulate the emission of harmful substances that various systems are come limiting engine, and Europe III, Europe IV Abgasgesetz as current various countries regulation require the discharging of the motor of various vehicles must reach standard.In order to achieve this end, producer has adopted various measures so that diesel engine satisfies emission standard, but, these measures are that motor is redesigned or motor is carried out big transformation to realize engine emission purpose up to standard mostly, not only the numerous Xu of technology, input cost are big, and produce effects neither be very obviously, caused great waste.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of unit-pump system diesel engine, and it has not only effectively solved the emissions of diesel engines problem, and less to the motor change, and control is simple.
For solving the problems of the technologies described above, the technical solution of the utility model is: the unit-pump system diesel engine, described diesel engine is provided with electronically controlled unit pump unit and electronic control system, described electronic control system comprises electronic control unit ECU and a plurality of sensor that is arranged on below, electronically controlled unit pump unit, and described electronic control unit ECU is communicated with sensor and electronically controlled unit pump unit respectively by wiring harness.
As a kind of optimal way, described electronically controlled unit pump unit is for to be provided with pump box and a plurality of monoblock pump on diesel engine, and described monoblock pump is fixed on the diesel engine by pump box, is provided with high-pressure oil pipe between monoblock pump and the diesel engine.
Adopt the unit-pump system diesel engine of said structure, owing to adopted the instantaneous working state of each working cell on the sensor detecting engine, and the signal that detects according to sensor by electronic control unit ECU, accurate control powers up time and then control injection time and fuel injection quantity after the computational analysis, guarantee of the fuel injection of best air fuel ratio with the control motor, allow the combustion mixture sufficient combustion, make motor reach best burning and emission effect, thereby reduce the harmful matter in the burning and exhausting material.Adopt pump box that monoblock pump and high-pressure oil pipe are connected and fixed on the motor, make that not only the structure of diesel engine is compact more, and the steadiness when having improved engine operation.
