To meet progressively stricter emissions regulations, the DF357 is designed to accommodate aftertreatment systems such as exhaust gas recirculation (EGR), diesel particulate filters (DPF), and selective catalytic reduction (SCR). These systems, integrated with engine control units (ECUs) that precisely manage air–fuel ratios and injection timing, help the engine comply with regional standards for NOx, particulate matter, and CO2 output while minimizing performance penalties.
The DF357’s racing record is a study in "what could have been." renault df357
To understand this, you have to understand how modern cars work. The ESP computer (the computer that handles stability and traction control) and the Engine ECU (the computer that runs the engine) are constantly talking to each other. To meet progressively stricter emissions regulations
