Anyone with driving experience knows how anxious it is to drive when the fuel gauge board points around Engo.
또한 차량 또는 장비를 운전함에 있어서 연료가 얼마나 많이 소모되는지, 연비가 얼마인지를 쉽게 판단하기 어려운 문제점이 있다.In addition, it is difficult to easily determine how much fuel is consumed and how much fuel consumption is in driving a vehicle or equipment.
이에 따라 본 발명의 목적은 연료잔량을 디지털적으로 표시함으로써, 연료가 얼마 남지 않았을 경우에도 운전자가 불안감 없이 운전하고 연비를 쉽게 알 수 있도록, 남은 연료량을 잘 알 수 있게 하는 연료잔량 표시장치를 제공함에 있다.Accordingly, an object of the present invention is to digitally display the fuel remaining amount, so that even if the fuel is low, the driver can be operated without anxiety and can easily know the fuel consumption, so that the remaining fuel amount display device can be well known Is in.
도 1은 본 발명의 일실시예에 따른 연료잔량 표시장치.1 is a fuel remaining amount display device according to an embodiment of the present invention.
도 2는 종래의 연료잔량 표시장치.2 is a conventional fuel remaining amount display device.
