From 2002 to 2015, the company produced the Mazda ZJ-VE 1.3-liter gasoline engine, which was limited to the base models of the first Mazda 3 and two generations of the Mazda 2 or Demio. A particularly cost-effective variant of this motor has the ZJ-VEM index and runs on the Miller cycle.

- 1.3 L – ZJ‑VE;
- 1.5 L – Z5‑DE, ZL‑DE, ZL‑VE, ZY‑VE;

- Mazda 2 DE in 2007 – 2015;
- Mazda Demio DY in 2002 – 2007;

Disadvantages of the Mazda ZJ-VE engine
The only thing that makes this engine prone to carbon formation is its dependability; if decarbonization is neglected, it will start to lose power before 100,000 kilometers; idle speeds frequently float due to throttle or EGR valve contamination;
The timing chain functions fairly well, but replacing it is challenging; there are no hydraulic lifters, so remember to adjust the valves every 90,000 kilometers.
