What engine does the BYD F3 use?
2 Answers
F3 currently uses the Dongan Mitsubishi 4G15S engine. Engine principle: A four-stroke gasoline engine mixes air and gasoline in a certain proportion to form a good mixture, which is drawn into the cylinder during the intake stroke. The compressed mixture ignites and burns to generate heat energy. The high-temperature and high-pressure gas acts on the top of the piston, pushing the piston to perform reciprocating linear motion, and outputs mechanical energy through the connecting rod, crankshaft, and flywheel mechanism. Engine composition: The engine consists of two major mechanisms: the crank connecting rod mechanism and the valve mechanism, as well as five major systems: cooling, lubrication, ignition, fuel supply, and starting systems. The main components include the cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc.
The BYD F3 is equipped with a 1.5-liter naturally aspirated engine, with a model designation like BYD473QE. I've studied the structure of this engine—it features a four-cylinder design with an aluminum alloy cylinder block for lightweight and better heat dissipation. It delivers a maximum power of approximately 80 kW and a torque of 145 N·m, with commendable fuel efficiency. While the official rating is just over 5 liters, real-world city driving averages around 7 liters. I find its performance smooth in daily driving without turbo lag, and the optimized noise and vibration levels make for a quiet ride, ideal for commuting. BYD has also upgraded the emission system to comply with the China VI standard, making it significantly more environmentally friendly than older models. Enthusiasts find it relatively easy to tweak for some performance gains during modifications. With high fuel injection precision and extended maintenance intervals, it stands as a reliable and economical power source, setting a benchmark in the compact car segment.
