Abstract
The utility model provides a starter control system of an ethanol fuel engine. The starter control system comprises an electric heating system for preheating ethanol fuel, an ECU (electronic control unit) in communication connection with the electric heating system, a relay with actions controlled by the ECU and a power supply supplying power to a starter, and the starter and the power supply are serially connected with a pair of normally open contacts of the relay. By the starter control system, the starter of the ethanol fuel engine can be prevented from being started before the fuel reaches target temperature.
Description
Technical field
The utility model relates to the motor car engine field, is specifically related to a kind of starter control system that just can allow starter motor work after the alcohol fuel preheating of finishing.
Background technique
Along with whole automobile industry develops rapidly to mixed power trend, in gasoline, add ethanol and can constant in engine displacement, not reduce under the prerequisite of performance, reduce noxious gas emission and fuel cost greatly.But alcohol fuel low-temperature atomizing weak effect, engine start is difficult unusually, so the alcohol fuel motor has increased electric heating system, fuel is preheated.But, if when fuel is not heated to predetermined temperature, the starter motor that the user pilots engine, though then starter motor can be worked, but it is successful that motor can't start, the work of heating is also fallen short of success for lack of final effort before the starting simultaneously, need restart heating, even can cause that motor " floods cylinder ".
The model utility content
The purpose of this utility model provides a kind of starter control system, is not started before fuel reaches predetermined temperature with the starter motor of avoiding the alcohol fuel motor.
For achieving the above object, the utility model provides following technological scheme:
A kind of starter control system of alcohol fuel motor comprises:
Alcohol fuel is carried out pre-warmed electric heating system;
The ECU that communicates to connect with described electric heating system;
Action is subjected to the relay of described ECU control;
Starter motor;
Power supply for described starter motor power supply;
Described starter motor and described power supply are connected with a pair of normally opened contact of described relay.
Preferably, the power of described starter motor satisfies following equation:
β=μ+（0.2~0.4）kw，
Wherein, β is the starter motor power of described alcohol fuel motor, and μ is the starter motor power of the gasoline engines identical with the discharge capacity of described alcohol fuel motor.
In to fuel heating process, because power supply and starter motor are connected with the normally opened contact of relay, so the starter motor that can't pilot engine, only after electric heating system is finished the fuel heating, electric heating system transmits signal to ECU, the action of ECU control relay, normally opened contact closure, starter motor can get electric starting, has therefore avoided the starter motor of alcohol fuel engine fuel not started before fuel reaches predetermined temperature.
Further, for the starter motor of alcohol fuel motor, during the big 0.2 ~ 0.4kw of the power of the starter motor of the gasoline engines of power ratio same displacement, the atomizing effect of alcohol fuel can be improved, energy waste can be do not caused simultaneously.
Description of drawings
Next will be described in further detail specific embodiment of the utility model by reference to the accompanying drawings, wherein:
Fig. 1 is the starter control system fundamental diagram of embodiment's of the present utility model alcohol fuel motor;
Fig. 2 is the starter motor control flow chart of embodiment's of the present utility model alcohol fuel motor.
The ECU(electronic control unit) 1, electric heating system 2, relay 3, starter motor 4 mark among the last figure:.
Embodiment
With reference to figure 1, alcohol fuel is carried out pre-warmed electric heating system 2 communicate to connect with ECU1, ECU1 control relay 3 makes the coil of relay 3 get electric or outage, thereby makes the movable contact action of relay 3.Starter motor 4 is used for piloting engine a pair of normally opened contact of SRE 3 between starter motor 4 and power supply (being generally storage battery).
In the present embodiment, the power of the starter motor 4 of employing satisfies following equation:
β=μ+（0.2~0.4）kw，
Wherein, β is the starter motor power of described alcohol fuel motor, and μ is the starter motor power of the gasoline engines identical with the discharge capacity of described alcohol fuel motor.
Because the starter motor power of alcohol fuel motor is than the big 0.2 ~ 0.4kw of starter motor power of the gasoline engines of same displacement, therefore the suction pressure in the intake manifold is lowered, further improve ethanol fuel oil low-temperature atomizing effect, more be conducive to engine start.The reduction degree of the too small then suction pressure of the power of starter motor 4 is not enough, the excessive electric power energy of then wasting storage battery of power.
Fig. 2 shows the starter motor control flow of alcohol fuel motor.In the preparatory stage, 2 pairs of alcohol fuels of electric heating system preheat, and before not reaching predetermined temperature, the coil of relay 3 must not be electric, and normally opened contact remains open state, so starter motor 4 can't be started.When the temperature transducer of electric heating system 2 detected alcohol fuel and reached predetermined temperature, electric heating system 2 stopped heating, sends to ECU1 simultaneously to stop heating signal.After ECU1 obtained stopping heating signal, the coil of control relay 3 got electric, relay 3 actions, and the normally opened contact closure, this moment, starter motor 4 can start, and then drove the alcohol fuel engine operation.
Though the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only be subjected to the restriction of claim, those of ordinary skills can easily make amendment to it and change, but do not leave essence design of the present utility model and scope.
