When will Mazda's SPCCI technology enter the domestic market?
2 Answers
Mazda's SPCCI technology was introduced to the domestic market on September 16, 2020. Here is a related introduction to the SPCCI technology: 1. Definition: The Mazda SPCCI version refers to models equipped with a SPCCI engine. The SPCCI engine adopts Spark Controlled Compression Ignition technology, combining the principles of gasoline and diesel engines. It uses ignition control for high-compression-ratio combustible gas, achieving more uniform and complete combustion through high compression ratio combined with ultra-lean combustion. 2. Applicable Models: The Mazda 3 Axela (also known as the Mazda 3) uses a 2.0-liter SPCCI engine with a maximum power of 132 kW and a maximum torque of 230 Nm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block.
I just came across Mazda's technical documents the other day, and their SKYACTIV-X compression-ignition gasoline engine was introduced in China in 2020. I remember it particularly clearly because it was first equipped on the Changan Mazda CX-30 launched in July that year, causing quite a stir among domestic media. This technology achieves a compression ratio of 15:1 in gasoline engines, using spark plugs to assist compression ignition, claiming a 20% reduction in fuel consumption. However, real-world tests found it has high fuel requirements, needing 95-octane gasoline to fully perform. Later, the 2021 Mazda 3 Axela also adopted it, but at a significantly higher price. Although it's still available in the 2023 models, the manufacturer's focus has now shifted to promoting hybrid technology.
