자동차 에어컨 사용 시 吸氣라인 改善에 따른出力 및 煤煙 特性에 關한 硏究

Abstract

In the case of turbocharger inter-cooled vehicles which uses diesel as fuel, some cooled air is manually suppled in the suction system through the evaporator and then the power (output) and smoke characteristics are analyzed.

1. If the air conditioner is turned on during normal driving, and a comparison is made between first step and fourth step, the power(output) decreases by 3.7% and smoke increases by 18.4% at the fourth step. 2. If the air conditioner is turned on when a separate line is connected to the suction air system, and a comparison is made between first step and fourth step, the power(output) increases by 3.1% and smoke reduces by 8.4%. 3. Through these two experiments in the suction air system, which works by connecting a separate air line, the temperature of suction reduces by 23℃ and the power(output) increases up to 9.6%. moreover, emission levels reduces by up to 42.8%. it's expected that it will be helpful for durability guarantee the turbocharger, and Average of the power is increased because of being good at burning state by treated the enough air due to be raised up to the air density into intake line overly. And then raised up to the air density, it is expected that will be increasing power that was good at burning state and will decrease the smoke.
