What does 1.5n mean?
2 Answers
1.5n displacement refers to the engine's displacement of 1.5L. Displacement is the volume of fuel gas in the cylinder when it is compressed to its smallest size, and the horsepower of a car is determined by the displacement. For family cars, a 1.5N displacement basically meets daily needs. The introduction to displacement and its classification is as follows: Introduction to Displacement: Displacement, a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or discharged per stroke or cycle. Car displacement is an important parameter for measuring a vehicle. Some domestic cars do not have the above-mentioned car model number on their rear, but their displacement is usually indicated on the body or rear of the car. Displacement Classification: The classification of car levels in China is determined by the size of the displacement. Mini cars have a displacement of ≤1.0L; compact cars have a displacement ranging from 1.0 to 1.6L; mid-size cars have a displacement ranging from 1.6 to 2.5L; executive cars have a displacement ranging from 2.5 to 4.0L; and luxury cars have a displacement greater than 4.0L.
I understand your question about the 1.5n designation. It actually stands for a 1.5L naturally aspirated engine, where the 'n' represents naturally aspirated. Unlike turbocharged engines marked with a 'T', it relies solely on piston-induced natural aspiration. This type of engine has a simpler structure and is much cheaper to maintain. I remember my first car had this kind of engine - while it didn't accelerate as fiercely as turbocharged cars, it was exceptionally smooth, with particularly responsive throttle control in city traffic jams. As for fuel consumption, with modern technology like Nissan's HR15 engine, it only consumes around 6L per 100km and runs fine on 92-octane gasoline. Though you do need to step on the gas earlier when overtaking on highways.
