Mazda, the Japanese automaker, introduced its groundbreaking gasoline engine, the 2.0 Skyactiv-G, in 2012. Despite not having supercharging, this engine boasts direct injection and an extraordinary compression ratio of 14 to 1. In this article, we will delve into the problems, reliability, and specifications of the Mazda 2.0 Skyactiv-G engine.
Performance
The Mazda 2.0 Skyactiv-G engine offers unique performance characteristics. With a maximum power output of 165 horsepower, this naturally aspirated engine delivers good dynamics, especially at low speeds. However, when driving on the highway, acceleration may slow down, particularly with an automatic transmission that restricts the driver from changing the gear ratio. Nevertheless, the engine is highly fuel-efficient and operates quietly.
Problems and Reliability
Although the Mazda 2.0 Skyactiv-G engine does not have any serious problems, there have been a few issues reported by drivers. One problem that has been encountered is a faulty flow meter, which causes the Drive Unit to stop functioning immediately after starting the engine. Fortunately, unplugging the device from the engine restores normal operation, but a replacement is still required.
Another issue that can lead to a significant loss in performance is a leak in the intake system. This leak allows additional air to enter the combustion chamber, altering the fuel mixture composition and reducing the effectiveness of the combustion process. Cracks in the intake manifold, although initially difficult to notice, are often the culprit behind this problem.
The third problem associated with the Mazda 2.0 Skyactiv-G engine is a damaged pneumothorax valve. Identifying the problem symptoms can be challenging as there is a lack of power and the engine operates louder than usual. In most cases, the repair shop will first replace the spark plugs and then the nox sensors, which can be quite costly.
To keep the Mazda 2.0 Skyactiv-G engine in good condition, regular servicing is highly recommended. Mazda advises changing the oil and filter every 12,000 miles or once a year. However, due to the engine’s unique and modern design, finding spare parts can be challenging, and they may only be available through the dealer.
Conclusion
Despite a few reported issues, the Mazda 2.0 Skyactiv-G engine has proven to be reliable and efficient. It has been used in various well-known Mazda vehicles and has gained popularity in the after-sales market. With its adequate performance and fuel efficiency, it is recommended for buyers looking for a gasoline engine.
Mazda 2.0 Skyactiv-G Engine Specifications
The Mazda 2.0 Skyactiv-G engine operates on the Atkinson cycle, which is also used by many Toyota hybrids. This cycle ensures high efficiency by not closing the valve at the start of the work cycle. Additionally, some Mazda 6 models are equipped with the i-ELOOP system, a kinetic energy restoration solution inspired by Formula One.
Here are the full specifications of the Mazda 2.0 Skyactiv-G engine:
- Maximum Power: 165 horsepower
- Fuel Efficiency: Highly fuel-efficient
- Performance: Good dynamics, especially at low speeds
- Intake System: Potential issue with leaks causing a loss in performance
- Pneumothorax Valve: Challenging to identify and repair
- Recommended Servicing: Change oil and filter every 12,000 miles or once a year
- Availability of Spare Parts: Original spare parts may only be available through dealers
- Reliability: Durability of 200,000 miles or more with regular servicing
In conclusion, the Mazda 2.0 Skyactiv-G engine offers remarkable technology and performance. While there have been a few reported issues, regular maintenance and servicing can ensure its longevity. With its reliability, efficiency, and adequate power output, this engine is a great choice for Mazda vehicle owners and buyers in the after-sales market.
