1. What is Engine Torque?

Engine Torque is defined as a rotating force produced by a engine's crankshaft due to power developed during power stroke in IC engine.

2. How Does the Calculator Work?

The calculator uses the Engine Torque equation:

Where:

• \( T \) — Engine Torque (Newton Meter)
• \( P_v \) — Power Required to Propel a Vehicle (Watt)
• \( N \) — Engine Speed in Rpm

Explanation: The equation calculates the torque produced by an engine based on the power required to propel a vehicle and the engine speed.

3. Importance of Engine Torque Calculation

Details: Engine torque calculation is crucial for understanding engine performance, vehicle acceleration capabilities, and overall powertrain efficiency.

4. Using the Calculator

Tips: Enter power required to propel a vehicle in Watt and engine speed in Rpm. All values must be valid (power > 0, engine speed > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between torque and power?
A: Power is the rate at which work is done, while torque is the rotational force. The relationship is defined by Power = Torque × Angular Velocity.

Q2: Why is the constant 9.55 used in the formula?
A: The constant 9.55 comes from the conversion factor between different units (60/2π ≈ 9.55) when converting from rad/s to RPM.

Q3: How does engine torque affect vehicle performance?
A: Higher engine torque generally means better acceleration and towing capacity, as torque determines the force available to turn the wheels.

Q4: What factors can affect engine torque output?
A: Engine design, fuel type, air intake, exhaust system, and engine tuning can all affect torque output.

Q5: How is engine torque measured in practice?
A: Engine torque is typically measured using a dynamometer, which applies a load to the engine and measures the rotational force produced.
