How can torque and horsepower curves be used to improve engine efficiency?
The ability to extend an engine’s speed-range allows it to stretch that torque curve out farther, provided that the high-speed efficiency is there to make horsepower. Power is torque multiplied by engine speed to produce a measurement of the engine’s ability to do work over a given period of time.
Why do engines have a torque curve?
The curve shows how much torque can be produced at each rpm point when the engine is running under maximum sustainable load. Maximum vehicle speed would be obtained by having the final drive ratio adjusted so the rpm where the torque is at the maximum can be reached but not exceeded.
What is the relationship between torque and horsepower?
Horsepower equals torque multiplied by rpm, divided by a constant. Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms. This is also why people talk about “low-end torque” being important for better power at slower speeds.
Is peak torque most efficient?
This torque peak is when the engine has reached its most efficient and maximum speed for that torque rating. Once a car is moving, torque is less important. For example, when cruising on the highway, the engine typically operates in its highest gear and at the lowest possible rpm.
Does more torque mean better fuel economy?
Fuel efficiency varies from vehicle to vehicle. During acceleration, however, fuel efficiency improves as RPM increases until it reaches a point near peak torque. If you consider this and choose between horsepower or torque, then one might say that torque plays a much larger role when it comes to fuel efficiency.
What is the torque curve?
plots the torque of a motor against the speed the motor is going at. The relationship between speed and torque varies dramatically across different types of motor and also between manufacturers.
What does torque curve mean?
1. The measure of a force’s tendency to produce torsion or rotation about an axis, equal to the product of the force vector and the radius vector from the axis of rotation to the point of application of the force; the moment of a force. 2. A turning or twisting force. tr.v.
Why do some engines make more torque?
The amount of torque produced is directly proportional to the air flowing through the engine. Large engines pump more air and, therefore, produce more torque.
What is the difference between engine horsepower and torque?
Simply put, torque is a way to measure force. Specifically, it’s a measurement of the rotational force within your car’s engine at the crankshaft. Horsepower, on the other hand, measures the amount of power that’s transferred from the engine to the wheels.
Whats the difference between HP and torque?
Torque expresses the turning ability of the engine (the ability to turn its flywheel) and horsepower means the total power output of the engine. In very simple terms, torque is the force you feel pushing you back in your seat on acceleration, while horsepower is the speed achieved at the end of that acceleration.
There is a relationship between torque and horsepower. However, a conversion is needed as horsepower measures the force needed to move a load over a distance, and the torque measures the force needed to move a load around a rotation or fixed point.
What is the formula for horsepower?
The formula for calculating horsepower using torque involves multiplying your engine’s torque and revolutions per minute and then dividing the product by 5,252.The horsepower of the Dodge Viper is 450, while the Ferrari 355 F1 runs with 375 horsepower.
How to calculate horsepower?
Weigh yourself. Find out how much you weigh in pounds. Write your weight down. If your scale uses kilograms, multiply…
What is rpm and torque?
Torque and Speed ( RPM) Are inversely proportional with each other Here is the torque-speed curve. As the RPM Of an engine increases, torque increases upto a certain value of RPM. And as the RPM goes on increasing, torque starts decreasing.
