    Engine Power
In summary, the conversation is about a person seeking help with their calculations on the Toyota Prius model. They found that the IC engine power they calculated was 162.1 kw, while the Toyota Prius specifications state it is only 73 kw. The person is confused about this discrepancy and is asking for assistance. The conversation also includes a discussion about the power output and the weight of the car. In the end, the person thanks the others for their help in finding the mistake.

Where are you getting your figures from?
What exactly is the question?
 
  • #3
the power i get is 162 kw and this is suppose to be 73 kw as toyota engine
what is wrong with my calculation ?
 
  • #4
Why is it supposed to be as the cars power output?

ie, How did you come up with that scenario.
Is it an official Toyota performance scenario, for the Prius?What you have shown is that a car that weighs nearly 1.8 tons cannot accelerate up a 1:5 hill at 0.18g at 60mph with the power output of a Prius. Which I would say is probably right.

Did you make up the scenario?

Total power available is obtained by adding the power from the engine and the power from the motors.

FAQ: What is the Discrepancy in Engine Power Calculation for Toyota Prius?

What is engine power and why is it important?

Engine power refers to the amount of energy that an engine can produce over time. It is an important factor in determining the performance and efficiency of an engine.

How is engine power calculated?

Engine power is typically calculated by multiplying the engine's torque by its rotational speed. This is known as the power equation: P = T * ω, where P is power, T is torque, and ω is rotational speed.

What are the units of engine power?

Engine power is typically measured in watts (W) or horsepower (hp). However, other units such as kilowatts (kW) and foot-pounds per minute (ft-lb/min) are also commonly used.

What factors affect engine power?

There are several factors that can affect engine power, including the type and size of the engine, the fuel type, air intake, and exhaust systems. Additionally, engine wear and tear, as well as maintenance and tuning, can also impact engine power.

How can I increase engine power?

There are several ways to increase engine power, such as upgrading to a larger or more efficient engine, installing performance parts, improving air intake and exhaust systems, and tuning the engine for optimal performance. However, it is important to note that these modifications should be done carefully and with proper knowledge to avoid damaging the engine.
