Fuel Injection Keeps Getting Better for Mississauga Motorists

Posted October 1, 2014 12:00 PM

Mississauga residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.

There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with airand before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.

Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.

For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same . The turbocharged version delivers 350 horsepower.

Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved fuel economy.

Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.

Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.

When fuel injectors get dirty, their precision drops off. The spray pattern won't be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and fuel economy for Mississauga drivers as well as delivering less power to the engine.

Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we're talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.

So keeping your fuel injectors clean is just good auto advice for Mississauga residents. The best way to do this is to change your air and fuel filters regularly and practice other habits of good vehicle care and preventive maintenance at Meadowvale Auto Repair Specialists Ltd. in Mississauga. Cleaning additives in your fuel can also help.

If you do end up with gum or varnish in your fuel system, you'll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.

Vive la Differential at Meadowvale Auto Repair Specialists Ltd. in Mississauga

Posted September 23, 2014 12:00 PM

There are a lot of drivers in Mississauga who are due for a differential service, but had never heard of a differential before. With front-wheel drive being so common in Ontario these days, the differential is just taken care of during a transmission service, so most Mississauga folks don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of your mind. It's not uncommon for people in Mississauga to not know they have a differential, let alone know that it needs service.

To better understand what a differential does, think about a track at any Ontario high school. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.

The differential compensates for the difference in speeds between the inside vehicle wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

It's a very important function. When you think of it, all the power to get a vehicle moving goes through the differential. Most cars weigh between 3,000 and 6,000 pounds (1,400 and 2,800 kg) – trucks even more. The power from the engine goes through the transmission and then through the differential to the drive wheels.

That's a lot of work and requires very heavy duty parts. And those parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool. The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that break down over time. So manufacturers recommend intervals for when to replace your differential fluid.

Your knowledgeable Meadowvale Auto Repair Specialists Ltd. service technician will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. He'll then replace the fluid and install the additives if necessary.

Your Meadowvale Auto Repair Specialists Ltd. service advisor can look up the vehicle manufacturer's recommended service interval or you can check your owner's manual.

At Meadowvale Auto Repair Specialists Ltd., we've been providing quality automotive service for our valued Mississauga customers since . If you need to schedule differential maintenance, or any other automotive service, give us a call at 905-821-4992.

Gear Up: Transmission Service at Meadowvale Auto Repair Specialists Ltd. in Mississauga

Posted September 17, 2014 12:00 PM

The transmission system in your vehicle allows you to change gears. Lower gears are power gears. They get your vehicle moving and get it up hills. Higher gears get the vehicle up to speed and get it rolling faster. If you have a standard transmission, then you have to do the work of shifting gears yourself. But with an automatic transmission, the vehicle shifts gears on its own. It automatically starts out in low gear and automatically shifts to high gears as it gets rolling. Again, it will automatically shift to a lower gear to climb hills or when you need a burst of speed.

How does it know when to change gears? Today's automatic transmissions are computer-controlled. The computer gathers information about what the vehicle is doing and changes the gears as needed.

Automatic transmissions are becoming more sophisticated all the time. More gears, or “speeds,” are being added. Almost all vehicles have at least four speeds. Five or six is common. Some are even increasing to seven or eight – up to ten. Adding gears has a lot of advantages for Mississauga vehicle owners: it improves fuel economy and increases performance.

But there is a drawback for drivers in Mississauga: more gears equal more parts and a more complex transmission system. Plus, all those parts need to fit into the same space as older, less complex transmissions. This means that today's transmissions are engineered to much tighter tolerances. In other words, they demand meticulous care from Mississauga drivers. Transmissions are designed for durability. But that durability can be compromised if they aren't given proper care.

That's why changing transmission fluid is such an important part of preventive maintenance for vehicles in Mississauga. Transmission fluid lubricates the transmission and keeps it in good working order. But if the fluid runs low, transmission parts will wear out quickly or suffer damage due to increased friction. The transmission can even fail.

Dirty transmission fluid can clog the small passageways in the transmission, blocking lubricant from reaching all of its parts. Again, this can lead to increased wear, damage or failure.

New transmissions aren't cheap. Repairing them isn't cheap either. But changing transmission fluid is fairly inexpensive at Meadowvale Auto Repair Specialists Ltd. in Mississauga. That's why responsible car care includes maintenance on the transmission system at Meadowvale Auto Repair Specialists Ltd.. It doesn't take a genius to figure out that periodic fluid changes aren't just good auto advice, they actually pay for themselves by preventing transmission repairs.

Talk to Meadowvale Auto Repair Specialists Ltd. About New Shoes for Your Vehicle

Posted September 11, 2014 12:00 PM

Custom wheels are one way that Mississauga folks express themselves and personalize their vehicle. But they aren't as cheap and easy as sticking decals on your back window. There are several factors that need to be considered, including cost, the fit of the wheel, modifications that will have to be made to the vehicle, how the new wheels and tires will affect the operation of the vehicle, your driving habits and, of course, the style of the wheels. Most Mississauga drivers start with the last factor: the style of the wheels. But that should be the last thing we choose.

When considering custom wheels, you should first carefully consider your budget. Some wheels may require adjustments to your vehicle suspension system, brakes, or traction systems. You need to know what you can afford before you start shopping or get your heart set on a particular type of wheel.

There are three basic ways you can change your wheels. First, you choose a wheel that is already the same size as the ones on your vehicle. Second, you can choose larger wheels and third, you can choose smaller wheels. Mounting wheels that are the same size as the ones already on your car sounds easy enough. But even though the wheel may be the same diameter as your current wheels, that doesn't mean it will fit your vehicle. Besides diameter, wheels also have an offset. This is the measurement from the inside edge of the wheel to the point at which it bolts on. If your new wheel does not have the same offset as your current wheels, your vehicle tires can rub on the inside or outside of the wheel well. This can lead to blowouts, uneven tread wear and other mechanical problems.

The tire and wheel professionals in Mississauga at Meadowvale Auto Repair Specialists Ltd. on 1705 Argentia Road can help you select a wheel that has both the correct diameter and offset for your vehicle. Or, if you really want a specific wheel in spite of the offset difference, your technician may be able to install adapters that will make the wheels fit.

Mounting larger wheels is a more involved process. There are several ways of doing this. You can mount larger wheels but keep the overall tire diameter the same. Or you can “supersize” your tire/wheel combo. Mounting larger wheels while maintaining the same overall tire diameter is the easiest way to increase wheel size. You still need to adjust for offset. Generally, this alteration means that your new tires will be wider than the originals, so you will have to install adapters to keep them from rubbing on the wheel wells. Consult your service advisor at Meadowvale Auto Repair Specialists Ltd. by calling 905-821-4992.

If you want to install larger wheels and increase the overall tire diameter, it is important that the package fits in the wheel well; you may have to do some minor modifications to your suspension. More importantly, you will have to reprogram your vehicle engine's computer to calibrate for the larger tire size. The computer calculates your speed based on the rotation of your tires, so increasing the size of the tires will render it inaccurate. Inaccurate speed calculations can mess up your anti-lock brakes and your stability control systems, as well as your speedometer and odometer.

As you can see, the more modifications you make, the more it becomes important to have your friendly and knowledgeable Meadowvale Auto Repair Specialists Ltd. tire and wheel professional help you with your car care.

If you really want those “super-sized” tires, great: just factor in the issues listed above, plus you may have to have modifications done to your suspension system.

The larger wheels and tires will add weight to your vehicle. This weight is not held up by the suspension system, so is referred to as “unsprung” weight. Adding unsprung weight affects your car differently than just adding loads inside of your car. Unsprung weight can affect acceleration and braking. Putting large wheels on your vehicle may require an upgraded brake system.

Also, you may not get the performance from your vehicle that you've been used to. It may be sluggish when accelerating or harder to handle when turning. You may also find that the ride is bumpier than it was before. Of course, done right at Meadowvale Auto Repair Specialists Ltd., a good wheel job can sometimes improve a vehicle's ride or performance. It just depends on your vehicle, the type of wheels you choose and what you are hoping to accomplish.

Now let's suppose you want smaller wheels on your vehicle. That should be easier, right? Not really. You still have to worry about offset, and it is important that your computer be reprogrammed to account for calibration issues. And you may need adjustments to your suspension system.

Remember your budget? All of these scenarios require that you shell out some money. Perhaps now you can see why it is good auto advice for Mississauga drivers to make that consideration first, before setting their heart on a specific type of wheel.

Another consideration should always be your driving habits. Do you do a lot of off-roading on the outskirts of Mississauga? Do you carry heavy loads? Do you tow a trailer on Ontario roads? All of these factors must be considered when replacing your tires and wheels. Some wheels just may not be up to the work you need them to do.

For example, if you mount large rims on your vehicle, then add low-profile tires to avoid major adjustments to other systems, they won't be able to handle off-roading as well as larger tires. There won't be enough sidewall on the tires to absorb the impact from off-roading. You could end up with dented or broken rims.

At the end of the day, Mississauga drivers should always put safety ahead of appearance. That's why you shouldn't add custom wheels to your vehicle without consulting with your Meadowvale Auto Repair Specialists Ltd. tire and wheel professional. Cutting corners when installing custom wheels by not making necessary adjustments to all of the systems impacted by the change can result in dangerous operating conditions as well as repairs down the road.

The friendly and knowledgeable auto professionals at Meadowvale Auto Repair Specialists Ltd. want to remind Mississauga drivers of the basics of vehicle safety: preventive maintenance, emergency preparedness and professional repairs. Stay safe, and stay on the road.

Why Is My Check Engine Light On?

Posted September 5, 2014 12:00 PM

The Check Engine Light strikes fear into the hearts of some Mississauga drivers, and is totally ignored by just as many. Just what it means is a mystery to most people.


Let's get the urgency issues out of the way first. If your Check Engine light is flashing, that means that something is wrong that could cause engine damage. Naturally, you need to get that taken care of right away. If your check engine light is flashing, you shouldn't drive at high speeds, tow or haul heavy loads. Take it easy all the way to your Mississauga service center.

Why

If the light is glowing steadily, you should keep an eye on it for a day or two. If the light doesn't go off, schedule an appointment with your friendly and knowledgeable pros at Meadowvale Auto Repair Specialists Ltd. to get it checked out.

Some more information on how the Check Engine light works may be helpful for Mississauga drivers. Most of your engine functions are controlled by a computer, not surprisingly, called an engine control computer. The computer is able to adjust many engine parameters for environmental conditions, engine condition and even the way you drive.

In order to make these adjustments, the computer relies on a network of sensors to provide data. The computer knows the proper operating range for each sensor. When a sensor reading is out of range, the computer runs some tests and may turn on the vehicle's Check Engine light.

A simple example is a loose or missing gas cap. This may cause one of the sensors to read out of range. The computer doesn't know if it's a serious condition that caused the reading or just a loose gas cap, so it stores a trouble code and turns on the Check Engine light.

Now when you tighten up the gas cap, the sensor readings will be in the correct range. The computer will keep checking on the report for a day or two. Since a bad reading didn't come up again, it turns off the Check Engine light. The computer will also try to make adjustments to compensate for some readings. If it can do so, it'll then turn off the Check Engine light.

If the problem can't be resolved then the light will remain on, and you should get your vehicle looked at. Your friendly and knowledgeable pros at Meadowvale Auto Repair Specialists Ltd. will plug a scanner into the on-board diagnostic port and read the trouble code stored in the computer. The trouble code will give the technician a starting place as he diagnoses the cause of the problem.
