Low-temperature starting system of double-section crawler-type all-terrain armored car

Abstract

The invention discloses a low-temperature starting system of a double-section crawler-type all-terrain armored car. The low-temperature starting system is connected with an engine cooling system through an electromagnetic valve, the low-temperature starting system and the engine cooling system are connected when low-temperature heating is needed, the low-temperature starting system and the engine cooling system are automatically cut off in other conditions, connection is stable and reliable, and it is ensured that the failure rate of a vehicle cannot be increased due to the heating system. A seventh water flow sensor, an eighth water flow sensor, a ninth water flow sensor and a four-way pipe with flow distribution are used for carrying out flow distribution on engine oil, a battery and an engine body according to respective required heating amounts, so that a very good heating effect is ensured to be achieved; a heater controller with program setting can realize reserved timing heating, real-time heating, heating temperature setting and heating duration setting; and a heater controller with an address code and a remote controller capable of freely adding codes can realize simultaneous one-key heating and remote control operation of multiple vehicles in the formation.

Description

Technical field [0001] The present invention belongs to the field of armored car launch control technology, and specific to a dual-stage crawler all-terrain armored car low temperature start system. Background technique [0002] When the vehicle is in a high-precision area, as the ambient temperature is lowered, the viscosity of the engine has increased, the fluidity is deteriorated, and the lubrication performance is deteriorated. It causes the engine operation resistance to increase; the temperature of the engine is lowered, the temperature of the combustion is reduced, and is in compression When the stroke is endpoint, the pressure in the cylinder is reduced, and the temperature will also reduce it accordingly. The ignition and oil supply cannot be well cooperated; the viscosity of the electrolyte in the battery will become large with temperature, and the particle movement is slow, the battery internal resistance Increased, resulting in decreased battery capacity, charge and d...

AI Technical Summary

Problems solved by technology

[0002] When the vehicle is in an alpine region, as the ambient temperature decreases, the viscosity of the oil in the engine becomes larger, the fluidity becomes poorer, and the lubricating performance becomes poorer, resulting in an increase in engine running resistance; the temperature of the engine body decreases, and the temperature in the combustion chamber decreases. At the end of the stroke, the pressure in the cylinder will decrease, and the temperature will decrease accordingly, and the ignition and fuel supply will not cooperate well; the viscosity of the electrolyte in the battery will also increase with the decrease in temperature, the movement of particles will slow down, and the internal resistance of the battery will increase. increase, resulting in a reduction in battery capacity, poor charge and discharge capacity, and insufficient power of the starter, which reduces the torque of the starter when starting the engine; under the influence of multiple factors, it will become extremely difficult or even impossible to start the vehicle

[0003] For the working environment of the double-tracked all-terrain armored vehicle, in some low-temperature environments, the ambient temperature is even as low as minus 50 degrees. If only low-grade diesel oil and the traditional method of air intake preheating are used, it is almost impossible to start normally. Forced starting can even damage the battery and starter
