Abstract

The invention discloses an intelligent data optimizing device of a diesel vehicle engine sensor. The device comprises a low-pass filter, an analog / digital converter, an arithmetic unit, an analyzer, adigital / analog converter, a local interface and a power supply management module; pressure signals in a high-pressure oil rail monitored by a rail pressure sensor and intake pressure signals of an engine intake main pipe monitored by an intake pressure sensor are transmitted into the analog / digital converter, and data obtained after conversion is sent into the arithmetic unit; an engine ECU sendsreal-time monitoring data and effect data to the analyzer for analysis to transmit into the arithmetic unit for comparison calculation with the data sent by the rail pressure sensor and the intake pressure sensor; then, the data is sent to the engine ECU, so that the engine ECU obtains more reasonable signals meeting present conditions; and when the power is improved, the unit time used for vehicle driving is shortened, and the unit oil injecting main quantity is reduced.

Description

technical field

[0001] The invention relates to vehicle data processing technology, belongs to the field of diesel vehicle engine peripheral equipment and diesel vehicle engine accessories, and in particular relates to an intelligent data optimization device for diesel vehicle engine sensors. Background technique

[0002] The amount of fuel injection controlled by the existing engine ECU depends on the fuel rail pressure and the opening time of the solenoid valve. The constant high-pressure fuel is directly or indirectly distributed to each fuel injector through the common rail, and with the aid of The opening and closing timing and quantitative control of the high-speed electromagnetic switch valve integrated on each injector controls the amount of fuel injected by the injector into the combustion chamber of the diesel engine. The fuel value does not fully play its role under different vehicle conditions, and some of them will not Necessary fuel consumption. Contents of t...
