The pistons Mazda's MZR 2.0-litre DISI petrol is the ideal engine to achieve this. The i-stop system, therefore, must use a direct-injection engine that can deliver fuel to the combustion chamber at high pressure, and that can easily ignite that fuel. (1) The engine must be able to inject fuel directly into the combustion chamber and ignite it; (2) an adequate amount of clean air must exist in the combustion chamber of the cylinder where the fuel is to be ignited; and (3) the computer control system must be able to determine which cylinder to fire immediately after starting the engine.

The engine is controlled with precision to make this happen: In order to use combustion energy from the initial stage of restarting the engine, and to start the engine quickly, the following three conditions must be satisfied while the engine is stopped. Developed solely by Mazda, it is the world's only idle-stop system that restarts the engine using the remaining energy in the pistons (with a quick help of the starter motor) by injecting fuel directly into the cylinder and igniting it to force the piston down and set the crank in motion. The Mazda 3 will be powered by the MZR 2.0L DISI engine with green idle-stop technology - Mazda's unique i-stop system. One way Mazda achieved this is to develop unique idle-stop technology that shuts down the engine when stopped in traffic jams and similar situations as a way to reduce fuel consumption. The Mazda stand at the 2009 Geneva Motor Show is greener than ever before.
