Cold-starting device of methanol automobile

Abstract

The invention discloses a cold-starting device of a methanol automobile, and belongs to the technical field of automobiles. The cold-starting device of the methanol automobile comprises a fuel tank, a cold-starting oil tank, a filter and a fuel oil spraying rail, wherein the fuel tank is connected with the fuel oil spraying rail through an oil inlet pipe, the fuel oil spraying rail is further provided with an oil return pipe connected with the fuel tank, the cold-starting oil tank is sequentially connected with the filter and a one-way valve B through liquid pipes, the liquid pipe of a connection section of the cold-starting oil tank and the filter is provided with a three-way pipe A, the three-way pipe A is provided with an oil return pipe connected with the cold-starting oil tank, and the one-way valve B is connected with the oil inlet pipe of the fuel tank through a three-way pipe B. The cold-starting device of the methanol automobile is good in cold-stating performance, simple in structure, low in cost, and convenient to arrange. The cold-starting oil tank is added to the automobile, the automobile can be started rapidly through the cold-starting oil tank, methanol fuel inside the fuel tank serves as power fuel after the automobile is started, and the problem that an engine can not be started rapidly by directly adopting the methanol fuel is resolved.

Description

technical field [0001] The invention relates to an engine starting device, in particular to a methanol automobile cold starting device. Background technique [0002] A cold start of the engine means that the engine has been started for a period of time since it was last shut down, and its internal temperature is consistent with the ambient temperature. Corresponding to it is engine hot start, which means that the engine is started when there is still a relatively high residual temperature inside the engine not long after it was shut down last time. [0003] At present, there are a large number of automobiles in the society. As the main energy used by automobiles, the consumption of gasoline is astonishing. Countries around the world, especially countries with large energy consumption, have included petroleum resources in their national economic development strategies. Methanol has replaced gasoline as a As the fuel for automobiles, its technology has become increasingly mat...

Problems solved by technology

However, due to the high ignition point of methanol, methanol is not easy to ignite successfully when the temperature is low in winter, and it is difficult to start the engine. Drivers often use special boilers to directly preheat the engine, or start the motor through an external power supply.

These methods are time-consuming, unsafe, and can easily shorten the service life of the engine and motor, and even cause certain damage to the engine and motor in severe cases.
