How many cylinders does the Song Plus have?
3 Answers
The Song Plus has a total of four cylinders. Powertrain composition of the Song Plus: The fuel-powered version of the Song PLUS is equipped with a 1.5T high-power engine, delivering a maximum power of 136kW. The engine is paired with either a 6-speed manual transmission or a 6-speed dual-clutch transmission. The electric version features permanent magnet synchronous motors with maximum power outputs of 120kW and 135kW, offering two range options: 405km and 505km. Function and types of cylinders: Cylinders are commonly used power components in mechanical equipment, converting the pressure energy of compressed air into mechanical energy to drive mechanisms for reciprocating linear motion, oscillation, or rotary motion. Single-acting cylinder: Only one end has a piston rod. Compressed air is supplied to one side of the piston to generate pressure, which pushes the piston to extend. It returns via spring force or its own weight. Double-acting cylinder: Compressed air is alternately supplied to both sides of the piston, generating force in one or two directions. Diaphragm cylinder: Uses a diaphragm instead of a piston, generating force in only one direction and resetting via spring. It has excellent sealing performance but a short stroke. Impact cylinder: This is a new type of component. It converts the pressure energy of compressed gas into the kinetic energy of high-speed piston movement (10-20 meters per second) to perform work. Rodless cylinder: A general term for cylinders without piston rods. There are two main types: magnetic cylinders and cable cylinders.
As a car enthusiast, I believe the BYD Song Plus DM-i hybrid version is equipped with a 1.5-liter inline four-cylinder engine, so the total number of cylinders is four. This design ensures smooth engine operation with minimal vibration, making it particularly suitable for daily commutes and family trips. In the hybrid system, these four cylinders don't operate continuously—they only engage when the battery needs charging, during uphill climbs, or high-speed cruising, working in tandem with the electric motor to enhance overall efficiency. This configuration optimizes fuel economy, making it more fuel-efficient than a pure gasoline vehicle. I've also noticed that the cylinder arrangement balances cost and performance, offering greater reliability compared to three-cylinder engines, with straightforward maintenance like oil changes and spark plug replacements. From a driving experience perspective, electric power takes priority during initial acceleration, and the cylinder activation transitions seamlessly without noticeable jerking, ensuring a more comfortable and reassuring drive. Overall, it's a smart choice for modern hybrid technology.
I recently bought the Song Plus DM-i, which uses a 4-cylinder engine, and it drives quite smoothly with minimal vibration. As an owner, I appreciate this design—the engine only kicks in when necessary, such as during long-distance highway driving, while electric power keeps things quiet in the city. The cylinder maintenance is straightforward, requiring only regular servicing to reduce the risk of malfunctions, making ownership hassle-free. If you opt for the all-electric Song Plus EV, there are no cylinders, but the hybrid's four-cylinder setup paired with a battery is practical enough. Overall, the driving experience is smooth, fuel consumption is low, especially in congested traffic where electric power dominates, sparing the cylinders and extending their lifespan without costly upkeep.
