What is the Relationship Between Horsepower and Torque?
1 Answers
Horsepower refers to the output capacity of the engine, while torque refers to the rotational force output from the crankshaft. Generally, a car with higher horsepower also has greater torque. The increasing horsepower and torque of cars currently on the market represent progress in engine manufacturing. More details are as follows: 1. Horsepower is an important parameter used to measure engine performance and can be converted into power, where 1 horsepower = 1 PS = 0.735 kilowatts. Horsepower indicates how quickly work is done and is related to speed, while the ability to pull a certain tonnage of cargo is related to torque. 2. For example, if Engine 1 has a power of 110 horsepower with a small displacement and a maximum torque of 140 Nm, and Engine 2 has a power of 90 horsepower with a large displacement and a maximum torque of 240 Nm, Engine 1 has higher horsepower but smaller displacement and torque compared to Engine 2. Therefore, Engine 2 can pull more cargo than Engine 1. 3. Higher engine power inevitably leads to higher fuel consumption, increased emissions, and pollution. For consumers and the environment, blindly pursuing horsepower or power is rather one-sided. In fact, the reason some domestic and international models can offer consumers a wide price range is due to the variety of engines, transmissions, powertrains, and electrical systems available from manufacturers. However, using a high-performance engine will significantly increase the price of the car.
