Problems solved by technology

However, in extremely cold regions, the air temperature in the cylinder is extremely low. If auxiliary heating measures are not used, the end-of-compression temperature in the engine cylinder cannot meet the requirements. Thermal resistance wire, etc., but the air intake preheating resistance wire has low heating power due to the power loss of the battery, and the contact area with the air is small, so it is difficult to increase the intake air temperature in a short time to meet the start-up requirements
In addition, at low temperature, the viscosity of the lubricating oil increases, and the frictional resistance between the moving parts of the engine increases. In addition, the low temperature causes the battery to lose power, and the power of the starter is insufficient, resulting in a decrease in the starting speed of the engine, making it difficult to start smoothly.

Abstract

The invention discloses an engine air intake and anti-freezing solution preheating combined system. The system comprises a controller, an air heating device, an anti-freezing solution preheating assembly and a communication pipeline, after external cold air is heated by the air heating device, then high-temperature air is input into an engine air inlet pipe through a pipeline, an anti-freezing solution is heated through the anti-freezing solution preheating assembly and then is transported to an engine water jacket, the air heating device and the anti-freezing solution preheating assembly areelectrically connected with the controller, and the controller is connected with a storage battery on a vehicle to realize power supply. The preheating combined system is independent of the vehicle, can realize air intake and high-efficiency preheating of an engine by using only a small amount of power supply through the storage battery on the vehicle and a small amount of oil supplied by an oil tank, thereby rapidly improving temperatures of air intake and the anti-freezing solution, improving a temperature of an engine oil, reducing a starting torque, and enabling the engine to be smoothly started under harsh low temperature conditions.

Description

technical field [0001] The invention relates to the technical field of automobile power systems, in particular to an engine air intake and antifreeze preheating combined system and a preheating method thereof. Background technique [0002] Two conditions need to be met for the engine to start smoothly. First, the compressed gas in the cylinder must reach the ignition temperature of the fuel, so that the fuel mixture can be ignited smoothly. Second, the engine speed must meet the set requirements. However, in extremely cold regions, the air temperature in the cylinder is extremely low. If auxiliary heating measures are not used, the end-of-compression temperature in the engine cylinder cannot meet the requirements. Thermal resistance wire, etc., but the air intake preheating resistance wire has low heating power due to the power loss of the battery, and the contact area with the air is small, so it is difficult to increase the intake air temperature in a short time to meet th...
