What Does An Exhaust System Do?

Just as gases are created whenever your vehicle’s fuel and air burn inside the combustion chamber, harmful fumes are also emitted as part of its normal operation. Meaning to keep you safe, your exhaust system carries those fumes away from the vehicle.

I know you only see the tailpipe on your vehicle from the outside, but there is a lot more to your exhaust system. So if you fail to properly maintain this important component of your car, it can negatively impact its performance.

  • The Exhaust Manifold 

They attach this to the cylinder head and take each cylinder’s exhaust and put them together into a single pipe.

  • The Oxygen Sensor 

Every modern car should have an oxygen sensor to measure how much oxygen is inside the exhaust. Note that this allows the vehicle’s computer to add or subtract fuel to get the correct mixture for maximum gas mileage.

Here is another component that is muffler-like which converts harmful carbon monoxide and hydrocarbons into water vapors and carbon dioxide. Sometimes it reduces harmful nitrogen oxides, which are mounted between your muffler and the exhaust manifold.

  • The Muffler 

What a muffler does is to quiet the exhaust to acceptable noise levels and absorb sound energy.

  • The Exhaust Pipe 

What this does is carry the gas out through your tailpipe. This is made of steel or stainless steel, however, newer car models may utilize aluminized steel for corrosion resistance.

What you should always remember is that the exhaust layout is more a function of design and intent rather than a parameter for the economy.

The fact that dual exhaust that is fitted in a car usually consumes more fuel is a direct consequence of how powerful and potent engines with which they may be fitted and not because the exhaust system itself causes more consumption!

This means that the type of exhaust system a car is fitted with stems from the type of engine car is equipped with!

So how does a performance exhaust affect gas mileage?

Remember that your vehicle’s exhaust system is more than just a metal pipe. Indeed, it is a major factor in your car’s performance; it goes down to gas mileage. So keeping your car exhaust system in good working condition can do a lot for your vehicle and of course, your environment. 

Ford fusion hybrid gas mileage dropping

A sudden drop in gas mileage can be blamed on several issues. Sometimes it can indicate some serious issue that if you leave unrepaired, can develop into an expensive repair.

Here are common reasons why  you might notice a ford fusion hybrid gas mileage dropping in your vehicle:

  • A Dirty Oxygen Sensor: 

The job of an oxygen sensor is to measure exactly how rich or lean the exhaust gases are whenever they leave the combustion chamber. Your vehicle’s computer uses this to adjust the amount of fuel entering the engine. So once the sensor becomes dirty or fails, it can lead to a drop in miles per gallon. This can also lead to failed emission tests and a rough idle.

  • A Dirty Fuel Injectors: 

The fuel injector must spray fuel into the cylinders where it is mixed with air and ignite. This means that over time, the fuel injector system can become clogged. Note that this can lead to a drop in fuel efficiency as well as slower acceleration and the vehicle not having enough power. But once you find out early, a simple cleaning of the injectors can solve the problem. 

  • A Bad or Dirty Spark Plugs: 

Your car spark plugs is what ignite the fuel in the combustion chamber. But if they are dirty or not working correctly, it can cause the engine to misfire, which leads to poor engine performance. Once this happens, it can lead to a lack of power as well as a big decline in fuel efficiency.

  • The Malfunctioning Mass Airflow Sensor: 

The mass airflow sensor is what detects the amount of air coming into the fuel injection system. This is what helps in delivering information to the vehicle’s computer, which crunches the numbers and then sends the proper amount of fuel to the air in the vehicle. So this means that a dirty airflow sensor will degrade fuel efficiently and lead to a rough idle and can even stall as the problem progresses.

  • A Misaligned Tires: 

Any car tire that is low or out of alignment can lead to a drop in fuel efficiency. Examining the tire pressure and having their alignment checked regularly can help in preventing this problem.

  • A Defective Fuel Pump: 

Most times fuel delivery issues can drastically affect fuel efficiency. Your car’s fuel pump pulls the fuel from the gas tank to the fuel injectors. Sometimes the fuel pump can become clogged or malfunction. This means that a bad fuel pump can lead to a rough running engine since it is not getting enough fuel. When this happens, it will lead to a decline in gas mileage. And once this issue is not addressed, it will lead to a rough idle, sputtering and stalling.

  • A Clogged Fuel Filter: 

Any clogged fuel filter will cause problems with gas mileage. Note that the fuel filter screens out contaminants in the fuel, and over time, it will become clogged. This means that your fuel filters need to be replaced periodically.

  • A Stuck Brake Caliper: 

Having a stuck caliper on a disc brake or a stuck shoe on a drum brake will lead to a serious decline in gas mileage. Additionally, any brake problem can make your vehicle dangerous to drive. However, if the decline in efficiency is accompanied by your vehicle pulling to one side, then the brake system should be inspected immediately.

Best car setup, modifications to increase mpg

A lot of drivers constantly challenge themselves in finding new ways to improve the fuel economy of their vehicles. Today, I bring the best car setup modification to increase mpg.

  • Fluid Modifications

One of the ways you can improve gas mileage is to use the lowest viscosity engine, transmission, and differential oils that are recommended by manufacturers. Note that thinner oil reduces resistance. Additionally, synthetic oils have more stable viscosities as temperatures change; so this can further decrease resistance. However, synthetic oils are more expensive but note that they tend to last longer since they don’t break down as quickly as conventional oils.

  • Grounding Cables

Your vehicle’s grounding wires and cables are an integral part of the car electrical system. And your vehicle depends on your electrical network–fuses, relays, and electrical wiring to operate some systems such as car lights, fans, stereos, and air conditioners. Note that all of these systems share common ground because they all connect to the battery’s negative terminal. 

And as the connections wear out or loosen, resistance increases (this happens because the amount of conductive material decreases). Because of this, everything in the electrical system has to work harder. What this does is lead to a variety of problems, which include slower throttle response and decreased fuel efficiency. Note that the quality grounding cables can help improve your car’s performance and the gas mileage for a relatively small cost.

  • Vacuum Gauges

Your vehicle’s vacuum gauge happens to be a low-cost, low-tech device that provides instantaneous fuel economy measurements as it monitors the manifold vacuum. Here is how it works: Any higher manifold vacuum equates to higher mileage. Just like other dashboard instrumentation, these dials will allow you to know how well they are driving in terms of fuel efficiency. With the help of the vacuum gauge’s feedback, drivers can learn to accelerate in some ways that maintain high and steady gauge pressure.

  • Real-Time Engine Monitoring

Note that these devices provide streaming data, which includes battery voltage, coolant temperature, and a real-time fuel economy readout. The fuel economy instrumentation can measure your fuel quantity data from the vehicle’s injection timing. Meaning that the longer the injectors remain open, the more fuel is released.

Can camphor reduce fuel consumption? 

You need to understand that it was used in the past to boost octane levels. The question is, the camphor or mothballs we have today does it contain pure Naphthalene? However, there are two types of camphor. The old kind is naphthalene. This is because it is ok to put this type in your engine.

The Naphthalene camphor was commonly put in fuel in the 50s-70s as an additive during street racing or hot rodding. This worked by improving the octane level rating of gasoline. But note that the octane rating of gas back then was fairly low. This means that the Naphthalene has an octane rating of 90, so it would boost the octane of gas considerably. 

However, remember that today’s gasoline is rated about 87 (regular) to 92/93 (Premium). This simply means that it will improve the octane of regular gas, but not noticeably. But the theoretical maximum octane rating which you can achieve by mixing camphor in regular fuel is less than 90. But if you add it to premium fuel, it will decrease your octane rating.

This means that if you already added some camphor to your ride, you should be ok. But make sure you don’t do it regularly as continuous use may cause carbon buildup and fouling of your sparkplugs.
