What is engine drag torque control?


Sharing is Caring


Engine Drag Torque Control (EDTC) is a system that applies additional torque (turning power) to wheels when needed to keep them rotating in order to prevent the car from sliding.

What is drag control?

To put it simply: Drag control is a load correction circuit that is designed to restore the optimal loading to your magnetic pickups. The Radial JD7 is the first product that was armed with Drag Control.

What is meant by drag torque?

Drag torque means the required torque to overcome the inner friction of an axle when the wheel ends are rotating freely with 0 Nm output torque.

How do you calculate drag torque?

Its fairly easy to compute friction torque. Each tiny surface area ds of body located at vector r experiences the linear velocity v=rร—ฯ‰ where w is angular velocity. So you just take that linear velocity, plug in to equation for linear drag to get the force dF exerted on that tiny area ds. Then you get torque dT=dFร—r.

What is engine drag?

Engine drag can occur on low and high coefficient surfaces when the driver suddenly releases the throttle. If the engine drag force becomes larger than the frictional force between the tire and the road, the tires will break loose from the surface and slip.

How does a drag valve work?

Unlike traditional control valves, the DRAGยฎ multi-stage, multi-turn technology divides the pressure reduction into many smaller stages. The number of turns, or stages, is selected to ensure a specific fluid discharge velocity is achieved at the exit of the control element.

What is torque in oil and gas?

Torque, is the rotational force between the drill string and the formation. There are two main causes of torque and drag, side forces and friction. Side forces include the forces that exist between the wellbore wall and any element of the drill string.

What causes drag on a car?

How is drag measured on a car?

Measure the speed of the car, disconnect the clutch and measure the time / distance until stand still (or a certain lower velocity). After that, you will know the deceleration of the vehicle, which is induced by the sum of drag forces. In this way, you can calculate (estimate) the total drag force.

How does drag force work in cars?

When you are driving along at a constant speed, the power produced in the engine is converted to force at the tires. The drag force acts in the opposite direction and is equal to the force that the engine creates at the tires.

Why is my car dragging when I accelerate?

What could the problem be? An acceleration problem is usually the result of insufficient fuel, air, or spark during the combustion process. Worn-out spark plugs or the electrical cables attached to them are one of the most common causes of cars stuttering.

Why does my car hesitate when I step on gas?

You may have water in the gasoline. If you have a carburetor, you may have a bad accelerator pump or power circuit. The Fix: Replace accelerator pump or clean or replace the carburetort. The fuel filter may be clogged.

How does a choke valve work?

By restricting the flow of air into the throat of the carburetor, the choke valve reduces the pressure inside the throat, which causes a proportionally greater amount of fuel to be pushed from the main jet into the combustion chamber during cold-running operation.

What is choke valve used for?

Choke valves are used to control flow rate and reduce pressure for processing of produced fluids farther downstream. Effective chokes reduce the likelihood of damage to downstream equipment, support longer lasting production timespans, and alleviate stress from field operators by keeping them away from the wellhead.

What does IMI PLC do?

We’re world-leaders in the design and manufacturing of specialist motion and fluid control technologies. We specialise in delivering severe application solutions for vital energy and process industries. We’re experts in energy-efficient hydronic solutions for heating and cooling in buildings.

Why torque and drag is important?

Torque and drag modeling is very important to analyze the mechanical behavior of the drill string and the wellbore condition, hence, to predict and prevent downhole problems. There have been a number of different approaches to the way that torque and drag has been modeled in the well drilling industry.

What is pick up and slack off weight?

Pick-up weight. It is the weight of the drill string while raising the string at a normal working speed. Most drillers raise the string too slowly. Be careful not to add in the load of accelerating the drill string and breaking gel of the mud. Slack-off weight.

How is drill torque calculated?

Force = Torque รท Length of the tong Force is perpendicular to the tong length. Example: Connection 4-1/2″ IF โ€“ required make up torque = 30,700 ft-lb.

How can I make my car less drag?

Methods of decreasing the drag coefficient of a vehicle include re-shaping the rear end, covering the underside of the vehicles, and reducing the amount of protrusions on the surface of the car.

At what speed does drag affect a car?

So, above 60 km/h, you need a lot of power to push the car to overcome the aerodynamic drag. The reduction in drag can help decrease a vehicle’s wind/air resistance. Thus, it helps to increase fuel efficiency to some extent.

How can I improve my car drag?

  1. Remove the Excess. In physics, drag is the force that acts in the opposite direction of a moving object to slow it down.
  2. Lighten Up.
  3. Use the A/C.
  4. Check Your Tires.
  5. Take a Look at Your Front Bumper.
  6. Use a Tonneau Cover for Your Truck.
  7. Keep It Clean.

What car has the lowest coefficient of drag?

  • Tesla Model S.
  • Toyota Prius.
  • Tesla Model X.
  • Kia Optima Hybrid.
  • Hyundai Ioniq.
  • BMW 5 Series EfficientDynamics Edition.
  • Honda Insight.
  • Mazda Mazda3.

Is higher or lower drag coefficient better?

A low coefficient is conducive to high top speed and low fuel consumption, while a higher drag coefficient is generally found in cars searching for high cornering speeds influenced by downforce. It shows that a car’s coefficient of drag can be found by analysing the drag force acting on the car at a given speed.

How do you calculate drag?

The drag equation states that drag D is equal to the drag coefficient Cd times the density r times half of the velocity V squared times the reference area A. For given air conditions, shape, and inclination of the object, we must determine a value for Cd to determine drag.

How does drag affect speed?

Does Drag Increase with Speed? As an aircraft’s speed increases, drag on the aircraft generally increases much faster. Doubling the speed makes the airplane encounter twice as much air moving twice as fast, causing drag to quadruple. Drag, therefore, sets practical limits on the speed of an aircraft.
