What does 1.5e mean?
4 Answers
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.
I've driven quite a few 1.5e cars, which is actually the code for a 1.5-liter engine displacement. The letter e stands for electronic fuel injection technology, much more advanced than old carburetors. This displacement is particularly fuel-efficient, I only get around 6 liters per 100 kilometers on highways, making it perfect for daily commuting. Although the power isn't particularly strong, it's completely sufficient for family outings. If encountering uphill sections, just press the accelerator a bit deeper. Nowadays many domestic cars use this powertrain configuration - like my family car that's been running for five years with only routine consumables like spark plugs replaced, the maintenance cost is truly low.
1.5e means it's equipped with a 1.5-liter electronic fuel injection engine. Last time I accompanied my friend to the repair shop, the technician pointed at the engine bay and said this type of engine has a simple structure, with injectors spraying fuel directly into the intake manifold, precisely controlled by the computer. Compared to older models, it starts particularly smoothly in cold weather - just turn the key and it fires right up in winter. However, be careful not to use low-quality gasoline. Once I filled up at a small gas station and the engine malfunction light came on. Remember to clean the fuel injectors every 20,000 kilometers during maintenance, otherwise carbon buildup can cause shaking.
When I was buying a car, I compared the 1.5e and turbocharged versions. The biggest feature of the 1.5e is its smoothness and durability, unlike the more delicate turbocharged version. Although the acceleration is slightly sluggish, it becomes very linear once the speed picks up. The engine compartment layout is also simple, making it particularly convenient to replace the air filter by yourself. The power may weaken a bit when the air conditioning is on in summer, but it's completely sufficient for city commuting. The manufacturer claims a combined fuel consumption of 5.8 liters per 100 kilometers, but in actual driving, it's around 7 liters, making it an economical and practical choice.
