What Engine Displacement is Equivalent to 136 Horsepower?
2 Answers
It is unrelated to displacement but related to power output. 136 horsepower can be achieved with an engine under 1.6 liters. 136 horsepower equals 100 kilowatts. Theoretically, larger engine displacement generally produces greater horsepower. However, in reality, the relationship between the two is not strictly linear, as it depends on the design philosophy and approach of the automaker. Below is expanded information about horsepower: 1. Cylinder Displacement: The volume of space through which the piston moves from top dead center to bottom dead center is called cylinder displacement. If an engine has multiple cylinders, the sum of all cylinders' working volumes is called the engine displacement, typically measured in liters (L). Generally, larger displacement means the engine can convert more chemical energy from fuel into mechanical energy per unit time, resulting in higher vehicle power. 2. Horsepower (PS): Refers to the engine's maximum power output, representing the work done by the engine per unit time, and is one of the units for measuring power. 1 PS equals 0.7457 kW, and 1 kW equals 1.36 PS. When people talk about how much horsepower a car has, they are essentially referring to the car's power output. The greater a car's power, the higher its horsepower, and consequently, the faster its speed.
136 horsepower is roughly equivalent to the output of a 1.5T turbocharged engine. I've driven several cars with this power level, such as the Civic and Focus. It's perfectly adequate for daily use, and overtaking on highways isn't a problem either. Back when I drove naturally aspirated engines, it took a 2.0L to achieve this kind of power, but now a small displacement with a turbo does the trick. When choosing a car, don't just look at the displacement figures—you need to test drive to feel the throttle response. My friend's 1.5T domestic SUV also has 136 horsepower, and it handles fully loaded uphill climbs with ease. However, turbo lag is a bit noticeable during cold starts, which isn't as smooth as larger displacement engines. Overall, 136 horsepower is quite suitable for family cars—fuel consumption isn't high, but the power is sufficient.
