Estimated power of a motor needed for a ford focus

In summary: These are the rules that you must follow in order to receive help. Good luck!In summary, the Ford Focus has an engine size of 1798cc, and it would require a starter motor with a power of 80N.m.

How do I calculate the estimated power of a motor needed for a ford focus, engine size:1788cc, 4 cylinders??

You need to provide some more information. Are you asking how much power a typical Ford 1.8L engine can produce? Or how much a 1.8L engine could theoretically produce? Or how much it actually produces? What information have you been given when you were asked this question?

I was told to choose a car, a petrol car, and using the engine size of the car(1798cc), work out the power of the starter motor the car would require. The cars specs are:

1798cc, 4 cylinders.

info given were:
2 cylinders= 125N.m
4 '' =80N.m
6 '' = 65N.m

Your question was obviously poorly posed from the start since you mentioned nothing about the fact that you are sizing the starter motor and not the engine itself. It seems that this is a homework assignment and so we will have to ask you first, what have you done to try and solve the problem thus far?

By the way, the displacement of the engine alone is not enough to determine the required torque of the starter motor. You will probably need to know things like the diameter of the flywheel (pitch diameter), diameter of the starter's pinion gear (pitch diameter), the engine's compression ratio, and probably the engine's bore and stroke. This may give you a very rough estimate, assuming you're ignoring friction in the cylinder.

A good response from Mech Engineer.

Also, I'm sure you won't just have been told that "2 cylinders = 125Nm"; this itself is meaningless.

If indeed this is a homework question, I suggest you read the rules for posting such questions and then have a go at following them. Then you'll get all the help you could possibly need.

A vehicle's engine rotates at 5640 rpm and produces 62 hp. If the final drive ratio is 4.00 and the transmission gear ratio is 3.00, calculate the vehicle speed, in mph. The tire radius is 10.1 inches. Vehicle is at constant speed.

Why don't you have a read of the rules we have here about homework questions? Remember, the ones you agreed to when signing up?
 

1. What is the estimated power of a motor needed for a Ford Focus?

The estimated power of a motor needed for a Ford Focus varies depending on the specific model and year of the car. However, on average, the power of a motor for a Ford Focus ranges from 100 to 200 horsepower.

2. How is the estimated power of a motor for a Ford Focus determined?

The estimated power of a motor for a Ford Focus is determined by taking into account various factors such as the weight of the car, the size of the engine, and the desired performance level. It is typically measured in horsepower (hp) or kilowatts (kW).

3. Is the estimated power of a motor for a Ford Focus the same for all models?

No, the estimated power of a motor for a Ford Focus can vary depending on the specific model. For example, a Ford Focus ST will typically have a more powerful motor than a standard Ford Focus.

4. Can the estimated power of a motor for a Ford Focus be increased?

Yes, the estimated power of a motor for a Ford Focus can be increased through modifications such as adding a turbocharger or upgrading the engine components. However, it is important to note that this may also affect the car's fuel efficiency and overall performance.

5. How does the estimated power of a motor for a Ford Focus impact its performance?

The estimated power of a motor for a Ford Focus plays a crucial role in its performance. A more powerful motor will typically result in a faster acceleration and higher top speed, while a less powerful motor may result in slower performance. It is important to choose the right motor for your specific driving needs and preferences.
