What does 1.5e mean?

[McMolly]

1.5e refers to an engine displacement of 1.5 liters, where 'e' indicates the basic version of the car configuration, 's' stands for the standard version, 'c' for the comfort version, and 'h' for the luxury version. The working principle of the engine: 1. Mix air and gasoline in a certain proportion to form a combustible mixture; 2. The intake stroke draws the mixture into the cylinder, where it is compressed, ignited, and burned to generate thermal energy; 3. The high-temperature and high-pressure gas acts on the top of the piston, driving the piston to perform reciprocating linear motion, and the mechanical energy is output externally through the connecting rod, crankshaft, and flywheel mechanism. The functions of the engine: 1. Fully burn the fuel input into the cylinder to generate power; 2. Determine the vehicle's power performance, fuel economy, stability, and environmental friendliness.
