Powerhouse for Reliability and Efficiency

Mazda ZY/ZJ 1.3L Petrol Engine is a compact yet durable 1.3-litre inline-four petrol engine designed for small to mid-sized Mazda models for example the Mazda Demio, Mazda 2, and Mazda 121. Furthermore, built under the Z-series family, the ZA engine represents Mazda’s focus on lightweight construction, smooth performance, and dependable daily use. With its DOHC 16-valve aluminium head and multi-point fuel injection system, this engine offers excellent fuel economy and low emissions while maintaining responsive power delivery for urban driving.

The Mazda ZY/ZJ 1.3L engine produces around 75–85 horsepower (56–63 kW) and 115 Nm of torque, giving it an ideal balance between efficiency and performance. It features a bore and stroke of 71.0 mm × 83.6 mm, a compression ratio of approximately 10.0:1, and runs smoothly on unleaded petrol. The engine uses a timing chain system instead of a belt, reducing long-term maintenance costs and improving reliability.

When it comes to maintenance and longevity, the Mazda ZY/ZJ 1.3L Petrol Engine stands out for its simplicity and low operating costs. However, as with most small-displacement petrol engines, some common weaknesses should be monitored over time. These include oil leaks from valve cover gaskets, rough idling due to carbon buildup on the throttle body, and occasional misfires caused by worn ignition coils or spark plugs. Additionally, regular oil changes every 7,000–10,000 km and timely air filter replacement help prevent premature wear and maintain peak efficiency. The timing chain tensioner may also require inspection after extended mileage to avoid rattle or slack issues.
