Problems solved by technology
[0003] Due to the structural characteristics of the ATV itself, the fuel tank generally adopts a rear structure, so the oil supply pipe of the oil pump needs to reach the fuel injector through a long route; in the prior art, the oil supply pipe follows the frame and is fixed by fixing parts , the oil pipe of this structure is longer, which increases the oil resistance of the oil pump, reduces the service life of the oil pump, wastes energy, and increases the difficulty of installation and layout, and requires related parts for fixing the oil pipe, and the installation cost is high

The invention discloses an ATV oil supplying system arranged on the back of an oil tank, which comprises an oil tank, an oil pump, an oil inlet pipe of the oil pump and an oil outlet pipe of the oil pump; the oil outlet pipe is arranged longitudinally along a vehicle body, aligned and connected to an oil sprayer of an engine. The device can shorten the length of an oil supplying pipe, so as to reduce the oil pumping resistance of the oil pump, improve the performances of the oil pump and the whole vehicle, reduce the oil pump load, prolong the service life of the oil pump, and save energy resources; meanwhile, the device omits related components used for fixing the oil pipe on a vehicle frame, reduces the difficulty of arrangement and saves the cost. A structure that the oil outlet pipe is embedded into a longitudinal oil pipe positioning slot on the oil tank, and an mudguard oil pipe positioning slot and the longitudinal oil pipe positioning slot are buckled on the outside of the oiloutlet pipe wall and position the oil outlet pipe is adopted. The oil outlet pipe is arranged between the oil tank and a back mudguard, so as to realize oil pipe positioning, firm and compact positioning and beautiful appearance.
Description
technical field [0001] The invention relates to an ATV auxiliary component, in particular to an ATV fuel supply system with a rear fuel tank. Background technique [0002] ATV (ATV) is a special vehicle that integrates entertainment, sports, and tourism. It can drive on various complex roads such as beaches, grasslands, mountain roads, and tourist places. ATVs have excellent performance, reliable quality, beautiful appearance, comfortable riding, sturdy and durable, and have broad market prospects. [0003] Due to the structural characteristics of the ATV itself, the fuel tank generally adopts a rear structure, so the fuel supply pipe of the fuel pump needs to reach the fuel injector through a long route; in the prior art, the fuel supply pipe is arranged following the frame and fixed by fixing parts , The oil pipe of this structure is longer, increases the resistance of the oil pump, reduces the service life of the oil pump, wastes energy, increases the difficulty of insta...
