Where is the engine of BYD Song from?
2 Answers
Song uses a self-developed engine, coded as BYD476ZQA, which is a 1.5L turbocharged engine. It features an aluminum alloy cylinder block for better heat dissipation and lighter weight, making it more fuel-efficient. Additionally, it adopts internationally advanced turbocharged direct injection technology, further improving heat dissipation and significantly enhancing engine stability. Below is relevant information about the BYD Song engine: 1. BYD's 1.5T engine was primarily reverse-engineered based on Volkswagen's 1.4T engine, marking BYD's first self-designed turbocharged engine. The turbocharger, supplied by BorgWarner (model KP39) like Volkswagen's, is equipped with a water-cooled bearing housing, enabling the BYD 1.5T to deliver a maximum power of 154 horsepower and a peak torque of 240 Nm, ensuring smooth acceleration across the entire engine speed range. 2. In terms of power parameters, this engine has a maximum output power of 154kW (113PS)/5200rpm and a maximum torque of 240Nm/1750-3500rpm.
As a guy particularly fascinated by automotive technology, I've been closely following the powertrain of the BYD Song. This car uses a self-developed engine by BYD, entirely manufactured locally in China. Specifically, in the DM-i hybrid version, their engine is called the Xiaoyun series, boasting a thermal efficiency as high as 43%, which is considered industry-leading. I've studied the test data before, and this engine integrates electric drive, with smooth transitions between fuel and electric modes, making it both fuel-efficient and powerful. As a full-value-chain company, BYD handles everything from batteries to engines in-house, which reduces supply chain risks and enhances reliability. However, it's still important to pay attention to software updates while driving to ensure system optimization. Overall, this Chinese brand is leading the trend in green mobility, with performance that rivals international giants.
