Embodiment Construction
[0013] Refer to attached figure 1 The diesel engine multi-fuel flame glow plug electronic intelligent control cold start device includes a start switch 1, an electronic controller, a fuel flame glow plug, a fuel delivery pipe 5, a solenoid valve 6 and a temperature sensor 8. Electronic control appliance control box 2, temperature control switch 3 and timer 4 are housed in the control box 2. Start switch 1 links to each other with electronic controller through lead, and start switch 1 is connected with power line, and temperature sensor 8 is contained on the intake pipe 9 of diesel engine, and temperature control switch 3 links to each other with temperature sensor 8 through lead. Fuel flame glow plug 7,11 is contained on the diesel engine intake pipe 9 respectively. There are at least two fuel flame glow plugs, which are installed on the intake pipe at the front end of the cylinder 10 respectively. The fuel flame glow plugs 7 and 11 are connected with power lines, and the po...

Description
technical field [0001] The invention relates to a diesel engine multi-fuel flame glow plug electronic intelligent control cold start device, which relates to an internal combustion engine diesel engine preheat cold start device. Background technique [0002] Vehicles using diesel engines as power engines are difficult to start in low-temperature environments without the use of auxiliary low-temperature starting devices. At present, the cold starting device of diesel engine generally adopts two kinds of electric heating and flame preheating. The former electric energy conversion heat energy consumes a lot of electricity, especially in cold areas with high latitudes, high current and long-term starting. The battery is struggling to hold enough power. The latter has a single flame glow plug, which makes the temperature of the engine cylinders uneven, individual cylinders are not easy to catch fire, excessive smoke is not conducive to environmental protection, and the engine i...
