When you buy a vehicle, the salesman often talks about horsepower. However, they rarely explain what horsepower actually is and why it is important for your car. Historically, horsepower means exactly what it sounds like it means.

What is Horsepower?

In 1781, James Watt needed to convince people to stop using horses and purchase his new steam engine. He measured a horse walking in circles as it turned a mill grindstone. He multiplied the distance the horse walked by the 180 pounds of pulling force, then divided it by the time it took, creating a new measurement known as horsepower. Basically, his calculations determined that a horse exerting 1 horsepower can raise 330 pounds 100 feet in one minute. Today, horsepower can be converted into other measurements. One horsepower is equal to 746 watts or 2,545 BTU. Basically, horsepower is the “power” of an engine.

What is Brake Horsepower?

Brake horsepower is the amount of work generated by a motor under the best conditions. It is calculated without the consideration of an auxiliary compoenent which could slow down the motor’s speed. Brake horsepower is measured in the output shaft of the engine and was originally created to measure the output of steam engines. Brake horsepower is critical for airplane engines and turbiens as it helps with the calculation of engine efficiency.

How Do I Calculate Horsepower?

To determine the horsepower of an engine, it must be connected to a dynamometer which places a load on the engine in order to measure the power the engine produces against the road. The dynamometer simulates starting an engine, putting it in neutral and then stomping on the gas. The dynamometer allows you to measure how much load an engine can take at various levels so that it can be graphed to determine peak horsepower.

What is the Difference Between Horsepower and Torque?

Horsepower is measured when the engine is at higher RPMs while torque is measured at the low-end. A diesel engine may only have 300 to 400 horsepower but could have 1,500 to 2,000 feet of torque. This allows trucks to pull heavy loads. Basically, horsepower is the power of the engine while torque is the rotating force that may or may not result in motion. Torque can be generated without moving something, but when it does move something, it becomes work. The more torque an engine has, the more work potential it has. Torque is important when a vehicle will be towing or pulling objects while horsepower is important when determining how much power an engine has.

Torque, like horsepower, is a word that car manufacturers like to use when they promote the vehicles they manufacture. The fact is that torque is just as important as horsepower although it isn’t often given the credit it deserves. In the 1980s, torque was rarely mentioned, in fact. Today’s cars, however, have a significant amount of technology, comfort and safety features which add to the weight of the vehicle. For this reason, torque is important to the engine to get the vehicle moving properly.

What is Torque?

Torque is the engine’s rotational force and is normally expressed in relation to an engine speed. A car feels more responsive when peak torque occurs in low rev ranges, but there are many people who enjoy driving vehicles with engines that must be revved significantly before peak torque is reached. The larger the vehicle, the more important torque is. For example, a tiny Smartcar does not need a lot of torque, but an SUV towing a boat will need a significant amount of torque.

How to Measure Torque

Torque is simply a mathematical equation and is computed by multiplying the force needed to move an object. If it takes you 20 pounds of force to tighten a lug nut on a vehicle with an 18-inch wrench, the equation would be “20 (lb) x 1.5 (ft) = 30 lb” of torque. In other words, tightening the lug nut would require 30 pounds of torque.

What is Braking Torque?

Braking torque is the force applied to the brake wheel to stop something from moving. In other words, braking torque is the power of the braking system. To determine braking torque, multiply the force exerted by the caliper with the effective radius of the system. Braking torque changes with the force applied by the caliper or the radius.

What is the Difference Between Torque and Horsepower?

Torque differs from horsepower as horsepower refers to how quickly an engine delivers work while torque explains how much work an engine can exert. Torque is often referred to as “pulling power” while horsepower is usually referred to as simply “power.” Torque is normally referred to in either Newton metres or pound feet.

What to Look for While Driving

While driving on a flat, dry road, you may notice that your car is pulling to one side of the road or the other. You may also notice that when you make slow turns, the car makes a squealing sound or that your steering wheel seems to be off-center. Your steering wheel may also vibrate as you drive. If your car is experiencing any of these symptoms, you need to bring it in for an alignment as soon as you can.

Tire Wear is Uneven

Your alignment determines how your tires meet the road. If you have noticed uneven tire tread on your car, it is possible your alignment may be off. Unevenly worn tires can also indicate that your wheel bearings are loose or worn. This can cause the tire to lean, leading to more wear on the inside or outside of the tire. It is also important to keep the right amount of air pressure in your tires to avoid alignment issues.

Alignment Checks

Even if you have not noticed issues with handling or wear on your tires, you should have the alignment in your vehicle checked at least once each year. If you routinely have your tires rotated, the service station should also check the alignment. During an alignment, a trained technician uses machinery known as the four-wheel alignment system to check whether alignment is necessary. Your car is placed on a large platform rack attached to diagnostic equipment. A visual inspection checks for suspension, steering and tire issues before the car is “driven” on the test platform. During the test, the machinery records the measurements of wheel and tire angles before comparing them to the manufacturer’s recommendations. Adjustments are made based on that recommendation to bring your car back into alignment.

If you have noticed handling issues or uneven wear on your tires after an auto accident, contact Elmer’s Auto Body today to schedule an appointment for a vehicle alignment. You can schedule the appointment by calling or completing the simple form online.

Your car is one of the largest purchases you will make, second only to your home. Like your home, the expense of a car does not end when you leave the dealership. According to the Bureau of Labor Statistics, your vehicle is the second-largest household expense, costing the average person $8,700 per year. Despite the fact that vehicle ownership can be expensive, there are things you can do to minimize your costs over the years.

1. Avoid Aggressive Driving

Aggressive driving practices like speeding, accelerating rapidly or hitting the brake hard can reduce your fuel economy. In fact, one study conducted by Oak Ridge National Laboratory found that aggressive driving can reduce your gas mileage as much as 33 percent.

2. Watch Your Speed

Once your speed exceeds 50 miles per hour, your gas mileage begins to decrease. For every five miles you drive over 50, you are paying an additional 20 cents per gallon in gas.

3. Turn Off the Engine

If you are waiting in your car, turn off the engine rather than letting it idle which can use up to a half gallon of fuel per hour. In contrast, only ten seconds of fuel is used when you restart your car. You also no longer need to warm up your car in the winter. Instead, drive slowly for about 30 seconds after you start it as the engine warms up more quickly when the car is being driven.

4. Limit Air Conditioning

Running your air conditioner can reduce your fuel economy by more than 25 percent. If possible, drive with the windows down. If it is too hot to do that, at least ride with them down for a short time before you turn on the air to let the hot air out of the car.

5. Motor Oil

One of the biggest mistakes people make is to use a grade of oil other than what the manufacturer recommends. This causes increased friction in the engine and can lead to lower gas mileage. If possible, choose an oil labeled energy conserving which means it includes additives that reduce friction.

6. Inflate Your Tires

Check the inflation on your tires often to be sure they are at the manufacturers recommended level. Proper pressure in your tires can increase your gas mileage more than three percent. Even if you have a tire pressure monitoring system, manually check your tires as electronic systems may not alert you until the tire is underinflated by five pounds.

7. There’s an App for That

There are several apps available that can help you reduce expenses for your car. GasBuddy helps you find the lowest gas prices in your area, for example. Just be sure to look for stations near your route as it is not costs effective to drive out of your way to save a few cents on gas.

8. Use Cash Back Cards

Many credit and debit cards now offer cash back options that can save you money. You may also be able to save using gas station loyalty cards that might offer reduced gas prices if you use their card for payment.

9. Shop Around for Auto Insurance

According to J.D. Power, only 39 percent of Americans searched for new auto insurance rates over the past year. When it is time to renew, look for quotes from at least four companies to be sure you are getting the best price.

10. Reduce Coverage on Older Vehicles

If your car is more than ten years old, you may be paying more in collision premium than the vehicle is worth. You can save up to 40 percent on your car insurance by eliminating collision coverage.

11. Insurance Bundles

Placing your house, car and other insurance with one company can save you on insurance as well. Some estimates are that bundling your policies can save you about 10 percent each year.

12. Limit Insurance Claims

If you are involved in a small accident where you are deemed at fault, you may be able to avoid filing a claim with your insurance company as long as the accident did not involve others and you were not injured. Filing a claim with your insurance could increase your rates by 40 percent.

13. Know Your Car’s Maintenance Requirements

Read your owner’s manual so that you understand what maintenance is required and when. Some mechanics will try to perform maintenance that is unnecessary. For example, they may suggest you have the transmission fluid drained and replaced although most modern cars do not need that service unless they have been driven over 100,000 miles.

14. Don’t Tailgate

Although this may seem like more of a safety tip, it can also save you money. Hard braking can reduce the life of your brakes. By easing to a stop rather than slamming on the brakes, you extend the life of your brakes as much as 30,000 miles.

15. Rotate Your Tires

Because front tires wear faster than rear tires, you can extend the life of all your tires by rotating them regularly. You can rotate them yourself or have them done when you take your car in for its regular oil changes.

16. Replace Air Filter

Your engine’s air filter keeps dirt out and improves your gas mileage. Therefore, it is recommended that you change the filter every 30,000 miles although your owner’s manual may have a different timetable. You can change the air filter yourself in less than five minutes.

17. Do Minor Repairs Yourself

You can do minor repairs to your car on your own. Replacing wiper blades is relatively easy and you can replace lights or fuses on your own. If you are unsure, search for how-to videos online or check your driver’s manual.

18. Oil Change Frequency

Most newer cars that use synthetic oil do not need the oil changed more than every 10,000 miles, although some mechanics will say it still needs to be done every 3,000 to 5,000 miles. Check your owner’s manual and stick to the schedule recommended by the manufacturer.

These tips can help you extend the life of your car and save you money over the years. For more information on how to maintain your car, schedule an appointment today by filling out the simple form online.

The “Check Engine” light on your dashboard is probably one of the most misunderstood warning lights in your car. Although the warning light may look ominous, it may be as simple as a loose gas cap or it could be as serious as a misfiring engine. If you are driving down the road and the light pops on, it does not mean you need to pull over and call a tow truck immediately, but it does mean you need to get the car checked as soon as possible. You do not want to ignore a check engine light, or you could face major repairs down the road.

What Is the Check Engine Light?

Since the 1980s, cars have more vehicle performance monitors that are part of thet onboard diagnostics system (OBD). The OBD regulates things like engine speed, ignition timing and fuel mixture. It may even tell your engine when to shift if your car is an automatic. When a problem occurs that cannot be corrected by the electronic controls system, a warning light is illuminated letting you know that you need to “check your engine.” The light may be the outline of a car engine, which is the International Check Engine Symbol, with the word “check.” When the light is illuminated, the engine stores a code that identifies the problem. Auto shops use a diagnostic computer to read the code and learn what the problem may be.

Emissions Systems

The OBD in cars manufactured after 1996 are also built-in emissions test systems. It constantly monitors and adjusts things like your exhaust system, your fuel system and other features that are related to your cars emissions. That’s why a check engine light could simply mean that your gas cap is loose as the computer thinks that your car is allowing gasoline vapors to escape into the atmosphere. Some states now check for stored trouble codes rather than using the tailpipe emissions testing system.

What to Do When the Check Engine Light Comes On

If your check engine light comes on, it may blink, or it may be a constant warning light on the dash. In some cars, a blinking light, or a check engine light that glows red instead of yellow, means the problem is serious and you should have it checked immediately. There are some models where a blinking light means a serious engine misfire. Check your owner’s manual and, if this is the case, reduce power and take the car to a mechanic as soon as possible. Look for other lights on the dash that may indicate a problem such as oil pressure or temperature. These lights indicate that you should pull over and turn the car off as soon as possible. Remove your gas cap and replace it tightly to see if the light goes out. Auto parts stores sell scan tools for around $40 so you can diagnose the problem yourself.

It is possible that your check engine light means a minor problem with your car. In some cars, the check engine light comes on when maintenance is necessary, like an oil change.
