Engine torque is a measure of the force that an engine can produce. It is typically measured in newton-meters (Nm) or pound-feet (lb-ft). Torque is important because it determines how well an engine can accelerate a vehicle and tow loads, especially at low speeds.
There are many different ways to increase engine torque including increasing the engine displacement, installing a turbocharger or supercharger, and modifying the camshaft. Increasing the engine displacement is the most straightforward way to increase torque, but it can also be the most expensive. Turbochargers and superchargers are devices that force more air into the engine, which can increase torque and power. Modifying the camshaft can also increase torque, but it is a more complex and expensive modification.
