Abstract

The invention discloses an inlet air heating device of a diesel engine. The inlet air heating device of the diesel engine comprises an oil inlet pipe, a pipe type electromagnetic valve, hinge tee joints, an oil outlet pipe, a filter connector, an electricity connection contact, a through hole, a threaded structure, a threaded-connection electricity connection device, a connector, a flange, an electric heating wire and a flame pre-heating plug, and is characterized in that the hinge tee joints are arranged on the left and right sides of the pipe type electromagnetic valve respectively; the hinge tee joint on the left side of the pipe type electromagnetic valve is connected with the oil inlet pipe; the hinge tee joint on the right side of the pipe type electromagnetic valve is connected with the oil outlet pipe; the other end of the oil outlet pipe is connected with the flame pre-heating plug; the connector is arranged on the left side of the flame pre-heating plug; the threaded-connection electricity connection device is arranged at the top of the flame pre-heating plug; the flange is arranged in the middle of the flame pre-heating plug; the electric heating wire is arranged at the bottom of the flame pre-heating plug. The inlet air heating device of the diesel engine is reasonable in structure, convenient to install, low in cost and capable of heating the air entering the diesel engine at the moment of ignition of the diesel engine, thereby improving the starting performance of the diesel engine and meanwhile reducing the serious vibration and white smoke rising phenomena of the diesel engine.

Description

technical field [0001] The invention relates to the technical field of automobile mechanical equipment, in particular to an air intake heating device for a diesel engine. Background technique [0002] Diesel engines are used in harsh environments, and some have been working in mining areas or alpine areas for a long time, and the cold start performance is affected. The diesel engine adopts the compression ignition type. In the cold start state, even if the air in the cylinder is fully compressed, part of the compression pressure will leak from the combustion chamber. In addition, the crankshaft rotates slowly when the engine starts, and the temperature of the intake air and the body is low. Therefore, The fuel injected into the cylinder has not risen to the self-ignition temperature, so it is necessary to use the flame preheating device to heat the incoming air to improve the starting performance of the engine, and at the same time reduce the phenomenon of engine knocking an...
