Ecological aspects of electronic diesiel control

Dziubiński M., Drozd A., Kukurudzyak Y.

ECONTECHMOD : An International Quarterly Journal on Economics of Technology and Modelling Processes

2017

Vol. 6, No 4

27--31

The article presents the simulation of damage to the engine power (EP) system components and to verify the impact of damage on toxic components emission. The other aim of the article is to simulate the failure of two sensors (the rail pressure sensor and the flow meter), which directly affect the toxicity, and to analyse signal paths during simulated damage. Simulation studies were conducted using the Oliver D60 ophthalmometer following the free acceleration method. Studies included driving a Toyota Avensis powered by 2.2D-4D diesel engine with 2AD-FTV designation and recording of thirty signals in the EP engine control system. The results will allow to correct the exhaust gas composition model.

Research into electronic control systems EDC

Dziubinski M., Drozd A.

ECONTECHMOD : An International Quarterly Journal on Economics of Technology and Modelling Processes

2016

Vol. 5, No 4

79--84

The article present proposed diagnostic procedures of the EDC 1.2.9 system made it possible to carry out tests and compare the results with the results provided by the manufacturer. As part of the research prior to diagnostic tests, verification tests of Siemens and Bosch pumps were carried out. Experimental study, test procedures making it possible to check particular elements of the EDC system were developed. The developed research program included the fuel system and tests were conducted for: the air intake system, engine sensors, vehicle sensors, the exhaust fumes emission system, transmitters and system elements on the controller connection. The second system, which was subject to experimental testing, was the injection system Common Rail (CR), on which tests of three sets of injectors were conducted. The following values were recorded: engine rotational speed, driver injection dose, pre-injection time, fuel dose in the main injection, fuel dose correction, the adjustment of idle running for the first, second, third and fourth cylinder. The conducted diagnostic tests make possible to predict the state of particular EDC systems reliability.
