What is the displacement for an engine with 92kW power?
2 Answers
92 kilowatts equals 125 horsepower. Introduction to horsepower: The concept of horsepower as a unit was named by James Watt, the improver of the steam engine, to represent the power of his steam engine relative to the pulling power of horses. It is defined as "the power of a horse that can pull 33,000 pounds and move at a speed of one foot per minute," with the standard units being watts (W) or kilowatts (kW). Engine power: Engine power refers to how quickly the engine performs work. The work done by the engine per unit time is called the engine's power. Corresponding to indicated work and effective work, it is termed indicated power and effective power (output power), with the difference between the two called mechanical loss power.
Well, 92kW converts to about 125 horsepower. I've done quite a bit of research on displacement. Generally, engines between 1.4 to 2.0 liters could achieve this, like my old 2.0L naturally aspirated car that produced exactly 92kW with smooth power delivery. But modern compact cars are different - a 1.5L turbocharged engine like in the Honda Civic can easily exceed 100kW while being more fuel efficient. Smaller displacement with higher output is possible thanks to turbocharging or direct injection technology, though actual power may drop slightly in high ambient temperatures or with poor maintenance. For precise matching, I'd recommend checking vehicle databases or using an app to input parameters rather than just guessing from numbers. Driving feel matters too - turbocharged cars have punchier acceleration, making them great for city commuting.
