start-stop start-stop technology allows the vehicle to automatically stop temporarily stop engine, thereby reducing fuel consumption, reduce emissions and traffic congestion especially in the big cities of the use of this technology has a good energy saving effect.
noun 1.Start-Stop technology explanation
cars in congested city traffic road, always found parking and other traffic lights, and engine idle energy consumption is meaningless. Start Stop technology is committed to minimizing the loss of fuel when the engine is idling, avoid this part of the energy waste, while saving energy and reducing emissions is significant.
When a red light or traffic jam, the driver brake to stop the vehicle, the gear shift into neutral and the clutch pedal is fully released, whereupon the control system will automatically turn off the engine, saving the fuel wasted while idling; when the green light, the driver depresses the clutch, the engine is automatically restarted, it can forward after engaging the gear.
operation easier and automatic models, as long as the brake is applied to the driver to stop the vehicle, the engine automatically turn off. After releasing the brake, the driver fuel, the engine will start automatically. This energy-saving driving style has not changed people’s daily driving habits, did not give the owner any trouble on the use, it has brought significant effect of fuel economy and emission reduction.
three ways 2.Stop-Start System
Stop-Start entry system as a hybrid vehicle technology (micro-hybrid), due to the low cost, energy saving effect is remarkable, which a bright future. Currently, Stop-Start system mainly in three forms:
separate starter / generator start-stop system, the integrated starter / generator start-stop system, Mazda SISS intelligent start-stop system.
3. Detailed separate starter / generator system start-stop
The separate starter and generator are common start-stop system. Starter and generator of this system is independent of the design, the power required to start the engine is provided by the starter, the starter and the generator provides electrical energy compared.
Bosch is a major supplier of such start-stop system. The system includes a high enhanced starter, enhanced battery (batteries generally employ AGM), controllable generator, integrated start / stop coordinator the ECU engine, sensors and the like.
Bosch starter motor quickly, quietly automatic recovery operation of the engine, fuel consumption can be reduced when starting. This system start-stop system fewer parts, easy to install, can be used in various hybrid concept (belt drive, direct shaft drive gear and the power drive). Further conventional components and system components consistent size, it can be directly provided to the various vehicles. Energizing the
4. Detailed integrated starter / generator system start-stop
integrated starter / generator and the rotor is a monodentate stator permanent magnet synchronous motor in vivo , the drive unit can be integrated into the hybrid powertrain system.
on the development of Valeo into i-Start System (i-Stop-Start System), which is first applied to the PSA (Peugeot – Citroen) model of e-HDi on. I-Start electrical system control device is integrated in the hairInternal motor, when an engine stall stop at red lights, a long-gear or releases the brake pedal the car will automatically start the engine immediately.
will be more than 10 Valeo automobile manufacturers with models 50 i-Start System. By 2013, there will be one million PSA models equipped with this system. French PSA Group, Mercedes-Benz and Smart are the main customers of Valeo Stop-Start system.
5. Detailed Mazda SISS intelligent start-stop system
The Mazda SISS intelligent start-stop system (now called i-stop technique), mainly by fuel injection in the cylinder, fuel combustion and expansion force generated by the engine restart, the conventional engine starter play a supporting role at engine start.
According to official data, the use of SISS technology, the engine can be started in the shortest possible time 0.35s, twice as fast than the simple use of the system, or the starter motor.
start-stop start-stop technology allows the vehicle to automatically stop the engine temporarily stop working, thus reducing fuel consumption, reduce emissions, especially in those traffic crowded cities using this technology has a good energy saving effect.
