Vehicle engine preheating device and preheating control method

Abstract

The invention belongs to the technical field of engine preheating devices, and particularly relates to a vehicle engine preheating device and a preheating control method. The device comprises a fuel tank, an engine, a radiator, a second heater and a controller. The fuel tank is connected with the engine through an oil conveying pipe, an oil-water separator, an oil conveying pump and a first heaterare fixedly installed in the middle of the oil conveying pipe in sequence from left to right, an engine water pump is fixedly installed on the top of the right side end of the engine, a water inlet is fixedly installed at the right end of the engine water pump, a thermostat is fixedly connected to the right side end of the water inlet, the thermostat is connected with the radiator, the bottom ofthe radiator is fixedly connected with the second heater, and a heater water pump is fixedly arranged at the bottom of the left side of the inner wall of the second heater. The comprehensive effects that cooling liquid preheating and fuel oil preheating are synchronously carried out, the preheating effect is improved, and engine failures are reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of engine preheating devices, in particular to a vehicle engine preheating device and a preheating control method. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is not only applicable to the power generation device, but also refers to the whole machine including the power device (such as: gasoline engine, aero engine). The engine was first born in the UK, so the concept of the engine also comes from English, and its original meaning refers to the kind of "mechanical device that generates power". The body is the skeleton that constitutes the engine, and is the i...
