Detailed Product Description: | Shandong Jining Wall Hong Trading Co., location and convenient transportation, the company's business objective is "Quality is the foundation for a fundamental service is the development of assurance." With "low price, good quality, perfect service" business philosophy implementing the company's overall business activities has always been. Why turbocharged engine than normal engine has more power, one of the reasons is its ventilation is more efficient than the naturally aspirated engine generally higher. When air enters the turbo after a dramatic rise in its temperature, density is correspondingly high, and the intercooler is played the role of cooling air, hot air passes through the intercooler cooling, re-entering the engine. If you are missing in the cold temperatures and let the pressurized air directly into the engine, it is because the air temperature is too high or even cause damage to the engine stalling phenomenon. Since the engine exhaust temperature is very high, the heat conduction through the booster will increase the intake air temperature. Moreover, the air is compressed in the process density will rise, which will inevitably lead to the air temperature, thus affecting the charging efficiency of the engine. If you want to further improve the volumetric efficiency, we must reduce the intake air temperature. Data show that the air-fuel ratio in the same condition, the charge air temperature is decreased 10 ℃, engine power can be increased by 3% to 5%. If not cooled pressurized air into the combustion chamber, in addition to affecting the pneumatic engine efficiency, very easily lead to engine combustion temperature is too high, resulting in knock and other faults, and will increase engine content of NOx in exhaust gas, causing air contamination. In order to solve the pressurized air warming adverse effects, requiring the installation of the intercooler to reduce the intake air temperature. |
