Normally, when your car is in idle mode fuel is still being used by the engine. To prevent the loss of fuel, you have idling stop systems which shut down the car’s engine when the car is static and restart when it is in motion.

Mazda’s spin on the idling stop system is its “i-stop” which improves fuel economy without compromising on the driving experience. Their control technologies restart the engine rapidly giving you a smooth operational feel. There is a slight difference in the operation of the i-stop technology for gasoline and diesel engines.

i-stop in gasoline engines

In a gasoline engine, Mazda’s i-stop restarts through combustion. When the engine stops, fuel is injected directly into a cylinder and ignited. This causes the engine to ignite quickly and quietly causing a significant amount of fuel saving. The precision and position of the pistons is controlled by the i-stop system which enables fuel ignition and engine restart. The restart takes approximately 0.35 seconds.

i-stop in diesel engines

Gasoline engines work on combustion, whereas diesel engines work on compression of the fuel-air mixture. Diesel engine idling systems need two engine cycles to restart. The i-stop uses only one cycle to do so. This can be done due to its precise control of the position of its pistons. As a result of this precision, the i-stop has the fastest diesel engine restart speed of approximately 0.40 seconds. Noise and vibrations during restart are so minimal they are barely noticeable.
