Abstract

An electric heating sleeve for a diesel engine oil nozzle pipeline comprises a sleeve used for being connected to the diesel engine oil nozzle pipeline in a sleeved mode and an electric heating strip embedded in the sleeve, a heat dissipation groove allowing the electric heating strip to be partially exposed out of the sleeve is formed in the inner side of the sleeve, and the part, exposed out of the heat dissipation groove, of the electric heating strip forms an exposed part. And the electric heating strip part hidden in the sleeve forms a hidden part. The device is used for guaranteeing normal work of the diesel engine under the extremely cold condition.

Description

technical field [0001] The invention relates to the field of fuel engines, in particular to an electric heating sleeve for a fuel injection nozzle pipeline of a diesel engine and a preparation method thereof. Background technique [0002] Diesel engine is an internal combustion engine that uses diesel as fuel. It belongs to compression ignition engine. It is often called Diesel engine after the main inventor Diesel. When the diesel engine is working, the air sucked into the cylinder of the diesel engine is compressed to a high degree due to the movement of the piston, reaching a high temperature of 500-700°C. Then the fuel is sprayed into the high-temperature air in the form of mist, and mixed with the high-temperature air to form a combustible mixture, which automatically ignites and burns. The energy released in the combustion acts on the top surface of the piston, pushing the piston and converting it into mechanical work of rotation through the connecting rod and cranksh...
