Effect of different lubricating oil formulas on the adaptability of cGPF aftertreatment

Based on two different components of lubricating oil, this paper analyzes the filtration efficiency, ash accumulation speed, vehicle WLTC emissions, fuel consumption, and CT scan on a National V emission standard engine equipped with a cGPF aftertreatment device. The results show that both oils can ensure that cGPF meets the emission and fuel consumption requirements of National VI emission standard, but oil F accumulates ash quickly before the ash accumulation of 33% in the discharge, which has a significant effect on PN reduction, and oil C accumulates ash faster after the accumulation of 33%. The effect of reducing the PN is accelerated. Oil F is based on a full calcium detergent system, which has a trend of first to slower for the collection efficiency; while oil C is based on a mixed Ca/Mg detergent system, which has a trend of first slowing and then fasting the collection efficiency. The critical point is generally about 33% of accumulated ash. For oil F, less ash is deposited in the front and middle of the cGPF, while more ash tends to deposit towards the outlet. In contrast, cGPF aged with Oil C has a relatively uniform deposition distribution.

ANALYSIS OF MODERN AUTOMATIC METHODS OF WASHING OF MILKING INSTALLATIONS

According to ISO 3918: 2007, ISO 5707: 2007 and ISO 6690: 2007, the detergent system must be designed and constructed so that detergents and disinfectants do not mix with milk. The proper functioning of the circulating detergent system depends on the following factors: the design and installation of the detergent system must ensure the proper volume of circulation, the speed and duration of the detergent solutions; temperature and concentration should be appropriate for the types of cleaning and disinfecting solutions. The purpose of the research is to analyze modern automatic ways of washing milking machines and to determine the basic modes of operation of washing machines. The washing machine is intended for washing and disinfection of milk systems and equipment of milking machines in cowsheds with a restrained method of holding and non-milking, whereby milking is carried out in the milking room. The washing machine is usually available in stock for standard and standard washing. The principle of piling is based on repeated use of water and detergent. The washing machine for standard washing is based on a circulating flushing system with a flow heater. Pre-rinsing and rinsing are done with water plugs.
