Low-temperature starting system of loader-digger

Abstract

The invention discloses a low-temperature starting system of a loader-digger. The low-temperature starting system of the loader-digger comprises a fuel tank and an engine and further comprises a liquid fuel heater, a controller and a switch. The fuel tank and the liquid fuel heater are connected through a fuel absorbing rod and a fuel conveying pipe. One end of the fuel absorbing rod is connected with the fuel tank, and the other end of the fuel absorbing rod is connected with one end of the fuel conveying pipe. The other end of the fuel conveying pipe is connected with the liquid fuel heater. The liquid fuel heater is fixed outside a shell of the engine, and an engine water inlet pipe and an engine water outlet pipe are connected with the liquid fuel heater. The controller is electrically connected with the switch and the liquid fuel heater through a wire harness. Fuel in the fuel tank is burned through the liquid fuel heater, cooling water in short circulation in the engine is preheated to 60 DEG C to 80 DEG C, and the purpose of preheating a body of the engine is achieved. Thus, the engine can be effectively started, and the natural environment suitability of the whole loader-digger is improved.

Description

technical field [0001] The invention relates to a low-temperature starting system of a backhoe loader, belonging to the technical field of control devices. Background technique [0002] In order to meet the market demand, backhoe loaders have higher and higher requirements in terms of adapting to harsh natural environments, especially in terms of effective starting of engines in low temperature environments. The low-temperature start of the traditional backhoe engine is only to add ether at the engine inlet, and use the low ignition point of ether to ignite. Although it can achieve the effect of starting the engine in a low-temperature environment to a certain extent, the effect of low-temperature start Unstable, limited adaptability to low temperature environment, affecting the performance of the whole machine. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a backhoe loader low-temperature starti...
