👉 Engine math, often used in automotive contexts, involves calculating the performance and efficiency of an internal combustion engine based on various parameters. Key equations include the power equation, which determines the engine's horsepower (HP) or torque (Nm) based on the displacement of the cylinders, the number of cylinders, and the compression ratio. The torque equation helps in understanding how much force the engine can exert, while the horsepower equation converts this force into rotational speed (RPM) to express power output. Additionally, the fuel consumption equation helps estimate how much fuel the engine uses per unit of power output, providing insights into efficiency. These calculations are crucial for tuning engines, comparing different models, and optimizing performance and fuel economy.
