Vehicle low-air-pressure low-temperature starting-up and driving room heating system

Abstract

The invention discloses a vehicle low-air-pressure low-temperature starting-up and driving room heating system which comprises a fuel oil heater, a temperature sensor, an electric control chip, a driving room heater and a fan heater; the outlet of the fuel oil heater is respectively connected with the inlet of the driving room heater and the inlet of an engine room through individual heating pipelines and a low-temperature starting-up pipeline; the outlet of the driving room heater is connected with the inlet of the fuel oil heater through the individual heating loops; the outlet of the engine room is connected with the inlet of the fuel oil heater through a low-temperature starting-up loop; the outlet of the engine room is connected with the inlet of the engine room through a heat circulating pipeline; the heat circulating pipeline is sequentially provided with a heat radiator, a tee and a water pump; the outlet of the engine room is connected with the inlet of the driving room heater through non-individual heating pipelines of the arranged valve; and the electric control chip is respectively connected with the fuel oil heater and the temperature sensor which are adjacent. According to the invention, the starting-up performance of a diesel motive power device in highlands and cold areas can be improved greatly, and meanwhile the driving room is heated.

Description

technical field [0001] The invention relates to the field of vehicle low-temperature starting and cab heating equipment, and more specifically relates to a low-pressure low-temperature starting and cab heating system. Background technique [0002] With the rapid development of society and economy in my country's plateau and cold regions, the number of diesel vehicles has increased sharply, and the demand for economical, simple and effective low-temperature starting and cab heating devices has also continued to increase, but the more effective low-pressure There are not many diesel engine low temperature starting and cab heating devices in low temperature environment. Low-pressure low-temperature starting and cab heating are common problems faced by vehicles in plateau cold regions, especially diesel engines are very difficult to start in low-pressure and low-temperature environments. [0003] Due to the high altitude (low atmospheric pressure) in the plateau area, low oxygen...
