The method of controlling the transport of the internal combustion engine on the dynamic idle and device for its implementation

 

The invention can be used in the engine when operating vehicles. The method of controlling the transport of the internal combustion engine (ice) mode, dynamic idle is to create cycles coasting and acceleration by the automatic exposure body fuel injection. Creating cycles coasting and acceleration is in the field of low frequencies of rotation of the crankshaft. The on and off mode dynamic idling occurs on signals of sensors pedal position clutch and shift lever of the transmission. Enabling occurs when the pedal is released the clutch and neutral position of the shift lever transmission, and off - press the pedal and(or) transfer lever from the neutral position into the working position. Device to control the transport of the internal combustion engine on the dynamic idling contains the transport engine, the generator speed, the actuator, the control unit mode dynamic idle position sensor unit high-speed mode and the switch. Set the contact position sensors pedal the knob speed consistently and included in the power supply circuit of the control unit. The technical result is to improve the quality of the transition of the internal combustion engine part of the vehicle with the operating mode on the dynamic idle and back. 2 S. p. f-crystals, 1 Il.

The invention relates to the field of engine construction and can be used when the internal combustion engine (ice) mode, dynamic idling during stops, Parking lots and traffic coasting vehicles.

Closest to the claimed invention relates to the method of controlling the transport of ice on the dynamic idle /1/ introducing cycles coasting and acceleration in the field of high frequencies of rotation of the crankshaft by an automatic impact on the authority fuel control when installing the unit of speed limits maximum speed shaft.

Device /2/ that implements this method contains the transport engine, the generator speed, the actuator and the control unit mode dynamic idling.

The disadvantage of the described method of controlling the transport of the internal combustion engine on the dynamic idle and device DL is a mini-idling as part of the vehicle, as the process of enabling and disabling dynamic idling is performed manually and is associated with additional actions of the driver.

The claimed invention aims to remedy these disadvantages and its implementation the following technical result: improving the quality of transition transport ice from the working mode to the dynamic idle and back without further action by the driver.

This technical result is achieved due to the application of the method of controlling the transport of ice on the dynamic idle, consisting in the creation of cycles coasting and acceleration by the automatic exposure body control fuel injection, thus creating cycles coasting and acceleration is in the field of low frequencies of rotation of the crankshaft, the on and off mode dynamic idling occurs on signals of sensors pedal position clutch and lever transmission, and enabling occurs when the pedal is released the clutch and neutral position of the shift lever transmission, and off - press the pedal and (or) the transfer arm from her is elsuwege the proposed method of controlling the transport of ice on the dynamic idle containing the transport engine, the generator speed, the actuator and the control unit mode dynamic idle, and the position sensor unit high-speed mode, the switch, the contact sensors pedal position clutch and lever gearbox, electrically connected between themselves and with the position sensor unit speed consistently and included in the power supply circuit of the control unit.

New significant features of the proposed method and device for its implementation lies in the fact that the on and off mode dynamic idling occurs on signals of sensors pedal position clutch and lever gearbox, electrically connected with each other and with the position sensor unit speed consistently and included in the power supply circuit of the control unit mode dynamic idling.

The use of position sensors in conjunction with the new control signals and electrical connections extends the functionality of the proposed method and device for its implementation, as it allows to improve the quality (slew rate and amplimo on dynamic idle and back without further action of the driver (this driver is similar to existing).

The transition of combustion mode with dynamic idling on the working mode as follows. Before starting the vehicle with a space by pressing on the clutch pedal and the gear is in the first stage is the transition to the steady-state idle mode in which the motor operates until pressing on the accelerator pedal. Then when pulling away and a gradual increase in the fuel is the acceleration of the vehicle in accordance with his passport dynamic characteristic.

The application of significant new features allows you to better manage the transport of ice on the dynamic idle.

The drawing shows a functional diagram of the device for controlling the transport of ice on the dynamic idle implementing method.

Device to control the transport of ice on the dynamic idling contains the internal combustion engine 1, the generator speed mode 2, the actuator 3 and the control unit 4 dynamic mode of idling, and also provided with a position sensor 5 knob speed mode 2, the switch 6, and the set of contact is e between themselves and with the position sensor 5 knob speed mode 2 in series and included in the power supply circuit of the control unit 4.

The operation of the device is as follows.

The switch 6 connects the device to power on-Board network of the vehicle.

When installing the unit speed 2 to the position "Minimum idle speed contacts of the position sensor 5 are closed. If the lever transmission is in the neutral position and the clutch pedal is released, the contact position sensors 7 and 8 will be closed, and the control unit 4, which, for example, the generator of rectangular pulses with a powerful output to the actuator 3 made, for example, in the form of an electromagnet DC and an anchor connected to the body of the fuel control, will be a rectangular pulse voltage with a frequency and a duty cycle proportional to the frequency of rotation of the crankshaft. In the cyclic opening and closing of the fuel (due to the moving body fuel control) are quanta coasting and acceleration - engine running in dynamic mode idling.

The operating time of the device, and hence the engine in the dynamic mode will depend on the duration of the stops on the clutch pedal and (or) transfer lever transmission from the neutral position into the working position, the contact position sensors 7, 8 are opened and the control unit 4 is disconnected from the supply voltage. The operation of the internal combustion engine is in normal load-speed mode.
