Abstract
The invention relates to a method for improving the starting performance of a diesel transportation vehicle. A power generator relay is added in a starting circuit of the existing diesel transportation vehicle, a coil of the power generator relay is connected with a starting contact b of a starting relay, a normally closed contact d of the power generator relay is connected with an electric power outlet end L of a power generator, and a base point a of the power generator relay is connected with a charger. The power generation function of the power generator during the engine starting can be closed through a new starting circuit provided by the invention, and the power generator function is naturally recovered after an engine is successfully started, so the front end accessory resistance of the engine in the starting process is reduced, and the starting process of the whole vehicle is accelerated. The starting time of the diesel transportation vehicle can be shortened, the low-temperature starting performance can be particularly optimized, and the once starting success temperature can be lowered by 3 to 4 DEG C in northern areas in winter.
Description
Technical field
The present invention relates to the DENG field, particularly a kind of method that improves diesel oil transport vehicle startability.
Background technique
The diesel oil transport vehicle is big with its power, good economy performance is occupied bigger transport market; But for gasoline car; The cold starting performance of diesel oil transport vehicle is poor, particularly in China northeast, northwest, southwest plateau area, winter is longer; Minimum temperature can reach below subzero 30 degree, and this has more increased the weight of the cold-starting puzzlement of diesel oil transport vehicle.In the Starting Process of Diesel Engine, the rotational energy that starter motor drags bent axle effective merit of diesel combustion need overcome motor during with starting internal friction resistance, frontal attachments resistance, the motor resistances such as resistance of calming the anger could finally start successfully.Now the middle and high shelves diesel oil transport vehicle of part has assembled double mass flywheel for driving comfortability, and the double mass flywheel generation of generally when 200-400r/min, can resonating, this has more strengthened the engine drag in the Starting Process of Diesel Engine.Particularly in the engine start process, after reaching certain rotating speed, generator meeting sudden startup electricity generate function increases the resistance of motor suddenly, thereby makes cold-starting difficulty more.
Summary of the invention
The technical problem that the present invention will solve provides a kind of method that improves diesel oil transport vehicle startability; Improve diesel oil transport vehicle starting circuit; The electricity generate function of generator when killing engine starting; And engine start success back electricity generate function recovers naturally, thereby reduces the frontal attachments resistance of motor in the starting process, accelerates the starting process of car load.
For solving the problems of the technologies described above, technological scheme of the present invention is: improve diesel oil transport vehicle starting circuit;
Be provided with storage battery, starter relay, starter motor and generator in the existing diesel oil transport vehicle starting circuit, use the electric starting DENG; When the driver got to " START " shelves with key, circuit was connected starter relay, starter motor and generator simultaneously, and starter motor also drags when starting DENG and is in the generator that is communicated with charging circuit.
The present invention increases a generator relay, the startup contact of the coil of generator relay and starter relay in existing diesel oil transport vehicle starting circuit
bConnect the normally-closed contact of generator relay
dPower output end with generator
LConnect the basic point of generator relay
aBe connected with charger; When the driver got to " START " shelves with key, circuit was connected starter relay and starter motor, the startup contact of starter relay
bConnect the coil of generator relay, the basic point of generator relay electric the time
aWith normally-closed contact
dBreak off, with normally-closed contact
dThe generator power output end that connects
LOpen circuit, even generator is driven to rotate, also be in the state that does not have load of electrical generation, the generator drag loading that is driven rotation by starter motor is minimum;
After the engine start success, key is got back to " ON " shelves, and when starter relay broke off, the coil of generator relay also cut off the power supply, generator relay recovery normally off, the normally-closed contact that is connected with the power output end of generator
dBasic point with the generator relay
aBe communicated with; Generator is in generating state, charges to charger; At this moment, generator is by the engine-driving after starting successfully.
Said starter relay is for often opening connection, and said generator relay is normally closed connection.
The invention has the beneficial effects as follows: after adopting the new starting circuit of diesel oil transport vehicle; The electricity generate function of generator in the time of can killing engine starting; And engine start success back electricity generate function recovers naturally, thereby reduces the frontal attachments resistance of motor in the starting process, accelerates the starting process of car load.Can shorten the starting time of diesel oil transport vehicle, particularly optimize cold starting performance, at north of china in winter, disposable starting success temperature can reduce 3-4 ℃.
Description of drawings
