Combustion Flow

Engine is carried the test on the thermal balance test and the drag test in the vehicle working condition to analysis the distribution of energy from combustion. The heat of coolant that combustion flow into the cooling system in different temperature is not the same. The results show that the engine heat comes into the cooling system ranging minimum at 3000-4000r/min, the effective power output accounts for the total energy up to 25% at full load reaching the maximum. Based on the data, it is established the control system of engine cooling module that can be controlled by the engine speed, torque and power, when the ECU reads the signal to forecast the combustion energy flow to the cooling system in the target vehicle working conditions establish the cooling module heat release control system.

The engine cooling module consists of condenser, radiator and fan (CRFM), which has long been recognized as a main source of sound and vibration in the automotive industry. As the engine becomes increasingly compact and powerful, customers gradually have higher expectations for automobile NVH performance than ever before. Thus the reduction of noise and vibration induced by CRFM becomes critical, which can greatly influence overall NVH performance. Combined with experimental and numerical methods, this paper focuses on the identification and optimization of steering wheel (SW) vibration induced by CRFM for a vehicle with V6 engine while engine idling. The numerical model established in this paper, based on Matlab and taking chassis vibration into account, can predict and optimize the vibration of CRFM under specific working condition with the help of energy decoupling and Newmark-Beta methodology. The optimization design of CRFM mainly involves the stiffness, position and angle of isolators. The numerical simulation results are validated experimentally, which can help further design of CRFM.

The Heat Balance

Cooling module simulation for vehicle has been built according to the heat balance test, and the simulation results are compared with the test data to verify the authenticity of the module. This simulation model provides an effective platform for vehicle thermal management analysis. Module is used to simulate the air conditioning running and to find how different ambient temperaturesto effect the performance of the cooling module. The air conditioning working and ambience temperaturewhichis significantly influence the performance of the cooling system.

The main function of an oil filter in a car is to filter the oil coming from the charter to be circulated to the engine. The main function of the oil between it is as a lubricant and engine coolant. The engine working temperature is affected by the engine cooling system and the oil function which acts as a cooler. One effort to improve the quality of oil cooling can be done with the addition of cooling aids placed in the oil filter. The purpose of this research is to determine the effectiveness of changes in the working temperature of the engine mounted cooling aids on oil filters. The method used to conduct research is the use of metal and aluminum based tools with the number of fins that are varied. The shape of the tool is a metal sleeve with fin fins that vary in number. The results of the temperature scale under the influence of engine speed in this study is the greatest level of decline with variations in the number of fins of 10oC. Whereas with the use of different materials, a 5oC reduction was obtained in the use of aluminum compared to stainless steels.

The article presents a comparative analysis of calculation results and measurement results of cooling module built on the basis of design calculations. The computations were made in software dedicated to the calculations of heat exchangers. The measurements were performed on a cooling system mounted in a special purpose vehicle together with a combustion engine, which was loaded by an engine dynamometer. Based on the comparison between input data for calculations and results of measurements, differences were found, therefore changes were proposed to be made in the model.

This paper describes the use of Fluid Flow Simulation Software to model a passenger aircraft engine environmental control system. The analysis simulates the cooling pack and the engine distribution system in a single model.The engine environmental system is very important for engine working efficiently. Using AMEsim software to simulate the cooling system can make it easily and clearly. The influence of the heat component and the fan operating is studied also. Through the analysis of the cooling system, we know that with the help of fan, the system can get additional air in the radiator and make the temperature decrease consequently.
