Improving Engine-Room Ground Resistance of a Power Source by Changing the Reference Point and Ground Reinforcement

In the engine room ground reinforcement work that secures the stability of the electrical device added in the first vehicle and reduces the ground resistance due to the aging of the vehicle, the existing battery ground standard work method and the main power source of the vehicle while driving By experimenting the method of changing the reference point to the alternator ground, we are trying to present a reasonable ground path. For engine blocks used as ground paths and cables used as reinforcing materials in an engine room environment where high heat is generated, TCR values according to temperature changes are measured and used as data for selection of reinforced cables. In addition, as a way to check the effect of ground reinforcement, experiment with changes in engine load factor, shift time lag of automatic transmission, and change in headlight operating current to confirm the objectivity of the ground reinforcement effect, and based on the results obtained from the experiment. It will be used as data that can be referenced in future engine room ground reinforcement work.
