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 ...

Abstract

The invention discloses an engine inlet air, crankcase and anti-freezing solution preheating combined system. The system comprises a controller, an air heating device, an anti-freezing solution preheating assembly and a pipeline for communicating, wherein external cold air is heated through the air heating device, then high-temperature air is input into an engine air inlet pipe and a crankcase airinlet channel in a crankcase through the pipeline, the anti-freezing solution preheating assembly inputs the heated anti-freezing solution into an engine cylinder cover and an engine body, the air heating device and the anti-freezing solution preheating assembly are both electrically connected with the controller, and the controller is connected with a storage battery on a vehicle to achieve power supply. The preheating combined system is independent of a vehicle, efficient preheating of engine inlet air can be achieved only through a small amount of power supplied by a storage battery on thevehicle and a small amount of oil supplied by an oil tank, the inlet air temperature and the anti-freezing solution temperature are rapidly increased, then the engine in-cylinder temperature and thetemperatures of all friction pairs of a crankshaft are increased, the starting torque is reduced, and the engine can be smoothly started under a harsh low-temperature condition.

Description

technical field [0001] The invention relates to the technical field of automobile power systems, in particular to an engine intake, crankcase and antifreeze preheating combination 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 ...
