Abstract

The invention provides a flame air inlet preheating low-temperature starting device. An air inlet pipe, a heater shell, a flame temperature sensor, a draught fan and a combustor are included. The airinlet pipe is provided with a small air outlet pipe and a flange for installing the heater shell. One end of the heater shell sleeves the small air outlet pipe, and an installing flange at the other end is fixed to the flange of the air inlet pipe. The draught fan and the combustor are arranged in the heater shell. The flame air inlet preheating low-temperature starting device has good low-temperature ignition performance, and ignition can be smoothly conducted at the environment temperature of -40 DEG C; good ignition continuity is achieved, after ignition, influences from the engine rotationspeed and displacement are avoided, and the defect that after a current flame air inlet preheating device is ignited, the rotation speed of an engine is increased, and blowing-out is likely to happenis overcome. Long-time ignition can be achieved, the single-time ignition time can reach 30 min or above, and the defect that after the current flame air inlet preheating device is ignited, long-timecontinuous combustion cannot be achieved is overcome.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a flame intake preheating low-temperature starting device for improving the low-temperature starting performance of a diesel engine. Background technique [0002] Flame intake preheating low-temperature starting device is a low-temperature starting device that uses diesel fuel as fuel. After being ignited, high-temperature flames are sprayed out and mixed with intake air to increase the intake air temperature and improve the low-temperature starting performance of diesel engines. It has the advantages of low power consumption, compact structure, and convenient installation, and is widely used in military and civilian diesel engines. [0003] The flame intake preheating low temperature starting device adopted by the current diesel engine is composed of a flame preheating glow plug, a controller and an oil circuit. The flame preheating glow plug is installed on the int...
