Before we speak about why gasoline does not burn quickly, it’s important to understand what gasoline is.
Gasoline is a liquid formed of carbon and hydrogen which is made up of carbon chains of different lengths ranging from C7H16 through C11H24. Imagine, if we could burn gasoline as a vapor with a hot flame and plenty of oxygen, we would get almost pure carbon dioxide and water as the combustion products. However, when it comes to an automobile exhaust, we need to consider that unfortunately it contains a lot more than carbon dioxide and water; for example, pollutants like carbon monoxide, nitrogen oxides, unburned hydrocarbons are part of it and might include some impurities like sulfur as well.
As we already said, gasoline doesn’t burn cleanly because of the arrangement of its carbon chains. Why and what are these pollutants exactly?
What is carbon monoxide (CO)? It is a colorless, odorless, and tasteless poisonous gas that is slightly less dense than air. Although it has no detectable odor, CO is often mixed with other gases that do have an odor. It is a poison that is produced when fuel is burned in an automotive engine because of incomplete combustion or from the incomplete burning of natural gas. One very important thing to know is to never let your engine run in a garage with closed doors. Carbon monoxide poisoning is a serious life threatening condition so be very cautious and always ensure that the exhaust of your car is not trapped in the garage.
Nitrogen oxides (NO) are produced from the reaction among nitrogen, oxygen and even hydrocarbons (during combustion), especially at high temperatures, formed from the heat and pressure found in a car engine.
Unburned hydrocarbons (UHC’s). UHCs are the hydrocarbons emitted after petroleum is burned in an engine. When unburned fuel is emitted from a combustor, the emission is caused by fuel avoiding the flame zones. During the combustion phase there is so little time that not all of the hydrocarbons participate in the reaction.
In my next post I will talk about technologies that make internal combustion engines better.
Whether you are driving alone or with passengers, safety should always be your top concern. Take driving seriously by following the below tips to avoid any type of distraction behind the wheel.
No distraction. If you are not driving alone and your passengers make a lot of noise that might be pretty distracting. Ask them not to talk loudly as it’s important for the driver to be maximum concentrated.
Forget about your cell phone. What can be more distracting than a cell phone? Avoid using cell phones when driving. A lot of car accidents happen because of texting while driving as this reduces driver’s reaction time. Don’t drive and text.
Take precautions when driving in the dark. Nighttime driving can put a strain on the eyes, however, sometimes driving at night is unavoidable. To make your nocturnal journey safe drive in a moderate speed, dim your dash lights and instrument panel and keep your windshield clean and your headlights in a good condition. Also, do not stare at oncoming lights as they can disrupt your concentration.
Don’t drive drunk. The worst thing you can do is to get behind the wheel when drunk. Alcohol causes a number of impairments that lead to car accidents. Even at low blood-alcohol levels, intoxication reduces reaction time and coordination and lowers inhibitions, which can cause drivers to make bad choices.
Do not drive when you are tired. All you need is to be very concentrated which is pretty hard when you are tired. Avoid driving when you are tired as drowsy driving is very dangerous.
Keep a safe distance. If a car makes a sudden turn or stop, drivers need enough time to react so don’t follow too closely.
Keep your vehicle safe. Vehicle maintenance isn’t just an important way to extent your car’s life – it’s a major safety issue. If your car is unsafe, your driving can’t be safe. At Pristine we will help you keep your vehicle safe, dependable and on the road longer.
We recommend you taking these driving safety tips very seriously.
Night driving is not just annoying, it is dangerous. Driving at night is actually the most dangerous time to drive.
What makes driving at night dangerous? Obviously it’s dark and we tend to be more tired at night. However, sometimes driving at night is unavoidable.
How does one make their nocturnal travels safer and better?
Here are some easy-to-follow tips for driving after dark; All you have to do is follow these steps and make sure your vehicle is ready for a drive at night:
1. Your headlights should be in a very good condition: Point your headlights perfectly, making sure they are not blinding to oncoming traffic. You don’t have to be a mechanic to do this, just follow the instructions of the manual. Clean the road grime from your headlights on a frequent basis. This is especially necessary if your car is an older model with plastic lens covers. This can be very dangerous as covers tend to yellow and fade over the years. Finally, to make sure nothing blocks the light and your headlights shine through brightly, remove the haze with the headlight polish kit.
2. Your windshield should be perfectly clean: If your windshield is dirty, it might cause glare at night. Clean it with a newspaper to remove residue. Do not touch the windshield with hands as you might leave handprints. Also, aim your exterior mirrors by cleaning and adjusting them properly.
3. Dim your dash lights and instrument panel: To avoid stray reflections dim your dash lights. Also, do not leave your map lights on as they might disperse lights all over the interior and shine into driver’s eyes.
4. Never stare at oncoming lights: Turn your gaze away from other lights on the road. Bright lights can disrupt your concentration. We recommend you take the night driving very seriously and avoid any type of distraction.
I hope these tips were helpful.
