Oil tank with cellular metal foam structure for vehicle

Abstract

The invention provides an oil tank with a cellular metal foam structure for a vehicle. The oil tank comprises an oil tank body with an oil inlet and an oil suction pipe, wherein the oil suction pipe in the oil tank body is provided with a fuel pump; the lower end in the oil tank body is filled with a wave-inhibition noise-reduction device made of cellular metal foam; an oil product is filled in the clearance of the cellular metal foam structure; and the oil suction pipe is inserted into the wave-inhibition noise-reduction device. The traditional wave-proof baffle is replaced by the cellular metal foam, so that the centroid of fuel shaking in the oil tank can be effectively lowered, the fluctuation of the fuel liquid surface can be inhibited, the liquid phase rate of the oil suction pipe and the periphery thereof of the oil tank can be remarkably improved, the flowing noise can be effectively reduced, and the safety, stability and comfort of vehicle running can be improved. Meanwhile, the oil tank also has the function of a filter so as to reduce blockage of an oil pump system and abrasion of a motion part, and improve the service life of an engine.

Description

technical field [0001] The invention relates to a fuel tank for suppressing fluctuations in oil products and reducing noise, in particular to a fuel tank with a through-hole metal foam structure for a motor vehicle. Background technique [0002] The fuel tank is a key component of the vehicle's fuel supply. When a motor vehicle brakes suddenly, starts, turns or passes through a road with poor road conditions, the fuel in the fuel tank will bump and oscillate. Especially when the fuel in the fuel tank is insufficient, the liquid level will fluctuate greatly. At some point, the oil product will be thrown to the side of the fuel tank, so that the oil suction pipe cannot absorb the oil, causing the engine to stall, which leads to the reduction of the anti-snaking performance of the motor vehicle In severe cases, it will lead to rear-end collisions on the expressway, or even rollover; at the same time, when the vehicle is insufficient in fuel, the violent non-linear flow of fuel ...
