A device called a Dynomometer (rolling road) is connected to the automobile wheels.
The engine is run at full throttle from idle to maximum RPM, then the engine is disconnected from the wheels (neutral) and the wheels allowed to slow down through the speed range.
A computer then calculates the engine torque and Horse Power.

What much is the power output of an engine that does 60000J of work in 10s?
The power output of the engine is 6000 watts (W). Power is calculated by dividing the work done (60000J) by the time taken (10s). This engine is capable of producing 6000 W of power.
What is specific fuel consumption and how it is calculated?
Specific fuel consumption (SFC) is a measure of the fuel efficiency of an engine design, typically expressed in units such as pounds of fuel per hour per horsepower (lb/hp·h) or kilograms of fuel per hour per kilowatt (kg/kW·h). It is calculated by dividing the rate of fuel flow (mass or volume) by the power output of the engine. For example, SFC can be calculated using the formula: SFC = Fuel Flow Rate (mass per time) / Power Output (power). A lower SFC indicates a more efficient engine, as it uses less fuel to produce a given amount of power.
Is the engine horse power representing the engine power or the thrust power at propeller?
Engine power.
What does indicated power and break power mean?
Indicated power refers to the power generated within an engine's cylinders, calculated from the pressure and volume changes during the combustion process, typically measured using an indicator diagram. Brake power, on the other hand, is the actual usable power output of the engine measured at the crankshaft, accounting for losses due to friction and other factors. In essence, indicated power represents the engine's potential output, while brake power reflects the real-world performance available for work.
How to calculate frequency in diesel engine?
To calculate the frequency in a diesel engine, you need to determine the engine's RPM (revolutions per minute) and the number of power strokes per revolution. The frequency can be calculated using the formula: Frequency (Hz) = (RPM × Number of Power Strokes) / 60. For a four-stroke engine, the number of power strokes is typically 1 per 2 revolutions, while for a two-stroke engine, it is 1 per revolution. Adjust the formula accordingly based on the engine type.
What is indicate horsepower and brake horsepower?
Indicated horsepower (IHP) measures the power produced by the engine's cylinders during combustion, calculated from pressure measurements in the cylinder and engine speed. Brake horsepower (BHP), on the other hand, reflects the engine's output power available at the crankshaft, accounting for losses due to friction and other factors in the engine. While IHP represents the theoretical power generated, BHP provides a more practical measure of the engine's performance as it relates to actual usable power. The difference between the two is often due to mechanical inefficiencies within the engine.
Calculated by multiplying the power on the objective by the power on the eyepiece?

What is a specific example of a machine and describe how its mechanical efficiency might be calculated?
An example of a machine is a car engine. Mechanical efficiency can be calculated by comparing the work output (such as the power produced by the engine) to the work input (such as the energy from the fuel). The formula for mechanical efficiency is: Efficiency = (useful work output / total work input) x 100%.
What is indicated power of diesel engine?
total power produced engine is called indicated power.
What is the formula of efficiency and power?
Efficiency is calculated as output power divided by input power, usually expressed as a percentage. Power is the rate at which work is done or energy is transferred, calculated as the product of force and velocity.
What kind of power does an automobile use?
Engine Power! Internal combustion engine.
How is brake horsepower measured?
Brake horsepower (BHP) is measured using a dynamometer, which assesses the engine's output power. The engine is run at various RPMs, and the dynamometer measures the torque produced, along with the rotational speed. BHP is calculated using the formula: BHP = (Torque (lb-ft) × RPM) / 5252. This measurement reflects the engine's power without any losses from the drivetrain or accessories.
