Especially in urban environments, stopping the start-up should create real-world differences, but will the durability of the engine be affected in the long run?
What is the stop-start technology?
Stopping the start is the system of most modern cars. When the car is stationary, it shuts off the engine to reduce fuel consumption and emissions. Ť His engine starts again W hen the hen clutch is engaged or disengaged, or when the driver Ready to move again.
Stop how to start working?
The system uses a computer to detect when the car is stationary or the car is stopped, at which point it stops fuel delivery and ignites the engine. When the car begins to move or presses the clutch, ignition begins.
This process happens automatically, but the driver can choose whether the system is activated or deactivated by pressing the stop-start button of the car; capital letter A, arrow clockwise rotation
Such a moment may occur when the driver decides to stop, but for whatever reason it will change his mind, for example when a traffic accident stops.
At this point the engine may 'stop' but still rotate, so to avoid smashing, a solenoid valve activates the starter motor to synchronize its speed with the engine, and then the second smoothly engages the gear.
Disadvantages of stopping startup technology:
Stop starting to wear my engine?
In terms of durability and long life, all foundations associated with the starter gear itself should be covered, but more stop-start cycles can result in increased engine wear unless measures are taken to prevent it.
'Ordinary cars that do not automatically stop starting may experience up to 50,000 stop-start events during their lifetime,' said Gerhard Arnold, who is responsible for the FederalMogul bearing design.
'But every time the car stops running, the automatic stop start is activated. This number will rise sharply and may reach 500,000 stop start cycles during the engine life.'
This is a big jump that poses a major challenge to the durability and longevity of engine bearings.
One of the most basic components of the engine is the crankshaft. It is supported because it rotates along many lengths of precision ground journals running in 'normal' main bearings (no ball bearings or rollers, only smooth metal) These are the main bearings, and the bearing behind the engine at the starter motor is more influential.
When the engine is running, the crankshaft and the main bearing surface are not actually in contact, but are separated by an ultra-thin oil film, supplied under pressure and pumped on the bearing surface by rotating the crankshaft. This process is called 'hydrodynamic lubrication'. But when the engine stops, the crank stops on the bearing and the two metal surfaces touch.
