Description

重型卡车的双油箱系统 Dual Fuel Tank System for Heavy Duty Trucks

技术领域technical field

本实用新型涉及重型卡车的油箱系统。The utility model relates to a fuel tank system of a heavy truck.

背景技术Background technique

现有长途运输用车大多需求双油箱以储备更多的燃油，减少加油的次数，增加行驶里程。而受整车布置空间的限制，轴距较短的重型车上在同一侧无法布置两个油箱，而为了保持两个油箱中油面的平衡，国内大多数做法是将油箱底部用油管连接。这种方法弊端较多，油箱底部开孔容易渗、漏油，连接油管容易断裂、堵塞等。为了能安装双油箱又避免以上存在的问题，需要一种新的布置及控制形式。Most of the existing long-distance transport vehicles require double fuel tanks to store more fuel, reduce the number of times of refueling, and increase the mileage. Due to the limitation of the layout space of the whole vehicle, two fuel tanks cannot be arranged on the same side on a heavy-duty vehicle with a short wheelbase. In order to maintain the balance of the oil levels in the two fuel tanks, most domestic methods connect the bottom of the fuel tanks with oil pipes. This method has many disadvantages. The opening at the bottom of the fuel tank is easy to seep and leak oil, and the connecting oil pipe is easy to break and block. In order to be able to install double oil tanks and avoid the above existing problems, a new arrangement and control form is needed.

具体实施方式Detailed ways

下面结合附图，通过实施例对本实用新型作进一步地说明。Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

实施例：Example:

参见图1，重型卡车的双油箱系统包括主油箱1和副油箱12，主油箱1上连通着出油管2、回油管5和连接油管A8，出油管2的另一端连接着油水分离器3的进油口，油水分离器3的出油口通过发动机进油管4连接着发动机7；连接油管A8的另一端连接着油泵9的出油口，油泵9的进油口通过连接油管B10连接着副油箱12；Referring to Fig. 1, the double fuel tank system of heavy-duty trucks includes a main fuel tank 1 and an auxiliary fuel tank 12. The main fuel tank 1 is connected to the oil outlet pipe 2, the oil return pipe 5 and the connecting oil pipe A8, and the other end of the oil outlet pipe 2 is connected to the inlet of the oil-water separator 3. The oil port, the oil outlet of the oil-water separator 3 is connected to the engine 7 through the engine oil inlet pipe 4; the other end of the connecting oil pipe A8 is connected to the oil outlet of the oil pump 9, and the oil inlet of the oil pump 9 is connected to the auxiliary fuel tank 12 through the connecting oil pipe B10 ;

参见图2，主油箱1和副油箱12上分别安装有主传感器13和副传感器14，主传感器13和副传感器14分别通过导线连接着油泵9和底盘电控单元16；油泵9通过导线连接着底盘电控单元16，底盘电控单元16通过导线连接着油量指示表15。Referring to Fig. 2, main sensor 13 and auxiliary sensor 14 are respectively installed on main oil tank 1 and auxiliary oil tank 12, and main sensor 13 and auxiliary sensor 14 are respectively connected with oil pump 9 and chassis electric control unit 16 by wire; Oil pump 9 is connected chassis by wire The electric control unit 16, the chassis electric control unit 16 is connected with the fuel quantity indicator 15 by wire.
