Abstract

The invention relates to the technical field of diesel engine aftertreatment, and particularly discloses a method for calculating a carbon black value of a diesel engine. The method comprises the steps that the working states of the diesel engine are judged according to the water temperature of the diesel engine, and wherein the working states of the diesel engine comprises a normal temperature state and a low temperature state; carbon black parameters of the diesel engine is collected, and a diesel engine carbon black calculation model is built through calibrating the carbon black parameters;if the working state of the diesel engine is the normal temperature state, the mass flow of the carbon black of the diesel engine at the normal temperature state are calculated through the diesel engine carbon black calculation model; and if the working state of the diesel engine is the low temperature state, and the mass flow of the carbon black of the diesel engine at the low temperature stateare calculated through the diesel engine carbon black calculation model. The invention further discloses a device for calculating the carbon black value of the diesel engine. The method for calculating the carbon black value of the diesel engine has the advantage that carbon black emission value of the diesel engine can be accurately estimated.

Description

Technical field [0001] The invention relates to the technical field of diesel engine post-processing, in particular to a method for calculating the soot value of a diesel engine and a device for calculating the soot value of a diesel engine. Background technique [0002] Diesel engines are currently widely used internal combustion power and have been used in automobiles, non-road machinery and marine power. In recent years, the emission pollution of diesel engines has received more and more attention. At present, the country has promulgated emission regulations on diesel engines, requiring that the emissions of diesel engines be gradually reduced to a controllable range. In order to realize that diesel engines meet the requirements of emission regulations, the exhaust gas of diesel engines needs to be post-treated to remove NOx and soot in the exhaust gas of diesel engines, so as to achieve the purpose of reducing diesel engine emissions. [0003] According to related studies, th...
