At what RPM does the Corolla 1.2T turbocharged engine engage?

[DeElena]

Corolla 1.2T turbocharged engine engages at around 1000 RPM. Introduction to the D-4T engine: The D-4T is a turbocharged engine, and the newly developed D-4T turbocharged engine adopts Toyota's latest dual VVT-iW variable valve timing technology, enabling seamless switching between Otto cycle and Atkinson cycle modes. When power and acceleration are required, the engine system operates in Otto cycle mode to ensure sufficient power performance; when the engine is under low load, it switches to Atkinson cycle to maximize efficiency and achieve optimal fuel economy. Corolla Turbocharging: The popularity of Corolla turbocharging is largely due to the domestic automotive market. Firstly, China's vehicle and vessel tax has implemented tiered fees based on engine displacement. The previously sought-after large-displacement naturally aspirated engines now mean paying a substantial annual vehicle and vessel tax. In contrast, small-displacement turbocharging not only avoids additional taxes but also delivers power performance comparable to large-displacement naturally aspirated engines. Therefore, the rise of turbocharging technology is justified.
