What Engine Displacement is Equivalent to 136 Horsepower?
2 Answers
136 horsepower is not directly related to engine displacement but rather to power output. Below are detailed explanations about horsepower: 1. Definition: Horsepower in automobiles refers to the unit of engine power, representing the engine's work capacity per unit time. It serves as a unit to measure an engine's performance and is also a crucial parameter for evaluating a vehicle's overall performance. 2. Influencing Factors: Horsepower is affected by factors such as displacement, compression ratio, turbocharging, and boost systems. 3. Calculation Formulas: Imperial horsepower (hp) = Torque (kg-m) × Engine speed (rpm) / 7272; Metric horsepower (PS) = Torque (kg-m) × Engine speed (rpm) / 7163.
I've driven quite a few cars before, and 136 horsepower is actually quite common in the family car segment. For example, a 1.4-liter turbocharged car like the low-power version of the Volkswagen Golf can steadily achieve this level with proper tuning. Naturally aspirated cars have to work harder, basically requiring a 1.8-liter displacement to reach around 136 horsepower. Last year, I tried an old Japanese naturally aspirated car with a 2.0-liter displacement that barely made over 140 horsepower. Nowadays, with advanced turbo technology, the same horsepower can be achieved with smaller displacements. However, it also depends on engine technology, vehicle weight, and transmission matching. For instance, American cars with the same displacement might have more torque but similar horsepower figures. If you're driving a compact SUV, 136 horsepower is completely sufficient for everyday overtaking.
