Problems solved by technology

If the driver forgets to switch the oil channel to a low-grade channel and stops the engine directly, the engine oil supply system pipeline is full of high-grade oil. After a long parking time, the high-grade oil in the engine pipeline will crystallize, resulting in failure to start or Difficulty starting

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0030] refer to Figure 1-2 As shown, a high and low label automatic switching fuel supply method in this embodiment includes the following steps of the fuel supply method:

[0031] Step 1. After starting the engine, the low-grade oil chamber supplies oil to the engine;

[0032] Step 2. The coolant passes through the low-grade oil supply engine and then flows to the high-grade oil cavity to heat it;

[0033] Step 3, the coolant returns to the engine to cool the engine;

[0034] Step 4. The temperature sensor in the high-grade oil chamber feeds back the temperature signal to the controller;

[0035] Step 5. The controller compares whether the temperature signal reaches the temperature threshold, and if it reaches the temperature threshold, enter step 6, otherwise return to step 1;

[0036] Step 6. The controller switches the high-g...

Abstract

The invention discloses a high-low label full-automatic switching oil supply method. The high-low label full-automatic switching oil supply method comprises the following steps that S1, oil supply of a low-label oil cavity is carried out; S2, a cooling liquid flows to a high-label oil cavity after passing through a low-label oil supply engine and heats oil in the high-label oil cavity; S3, the cooling liquid returns to the engine; S4, a temperature sensor in the high-label oil cavity feeds back a temperature signal to a controller; S5, the controller compares whether the temperature signal reaches a temperature threshold value or not; S6, the controller is used for switching the high-label oil cavity to supply oil; S7, whether the parking action is executed or not is judged; S8, the engine is shut down in a delayed mode, and the controller controls the low-label oil cavity to supply oil; and S9, after the oil supplied by the low-label oil cavity fills the engine and an oil pipe, the engine is shut down. According to the oil supply method, when a driver needs to park a car, after the driver sends a parking command, automatic analyzation and operation can be achieved according to a parking signal, the parking command is issued to the engine in a delayed manner, and the operation action of the driver is reduced.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a fuel supply method for fully automatic switching between high and low marks. Background technique [0002] At present, many diesel vehicles have dual-fuel systems that are already in use. Generally, only one type of fuel is installed. For example, the fuel tanks of trucks are generally filled with No. 0 diesel. However, when the temperature drops or when driving in the northern region, No. 0 diesel oil will often crystallize, causing blockage of the oil circuit, making it difficult to start the engine, or the engine will automatically shut down during operation. If the fuel tank is filled with low-grade fuel in the applicable temperature range, such as -10 diesel oil (4°C to -5°C), -35 diesel oil (-14°C to -29°C), although it will not crystallize, but the low grade Fuel is less powerful and economical than high-grade diesel, thus increasing transportation costs.
