Guest Post: 10 ways technology advances have helped reduce emissions in modern cars

[Clean Air Watch is pleased to present this guest post by Amanda Grison]

Automotive manufacturers have to produce vehicles that are not only fuel-efficient, but which will reduce carbon dioxide (CO2) emission. The following are the 10 ways which shows how technology advances have helped reduce emissions in modern cars.


Turbocharging
Turbochargers are popular for making vehicles go faster. But they are now leading in the race towards reducing carbon dioxide (CO2) emission. Industry leaders agree that turbo technology is a cost effective route to achieving the needed results. The primary concept of turbochargers is recycling energy from the exhaust gas and therefore transforming more of the consumed fuel energy into power. Therefore, turbocharged engines provide better fuel economy, lesser carbon dioxide emission and better performance as compared with the non-turbocharged engines.

Synthetic oils
Even though synthetic oils will appear expensive at the first sight, they are better than conventional oils for long-term health of your vehicle. Producers make this oil from chemical products or refine it from the naturally occurring crude oil. The oil helps reduce the vehicle’s wear during cold start up, increases fuel economy and reduces carbon dioxide emission to the environment.

Machined camshafts
Popularity of machined camshafts is increasing in the marketplace. That is particularly due to their efficiency in reducing weight compared to the one-piece counterparts. The camshafts have also started making their way into the truck sector. Some of their benefits include lower weight, lower cost, great flexibility during production and the option of different materials application for constituent components. The camshafts also help minimize fuel consumption and CO2 gas emissions.

Low resistance tires
Low rolling resistance tires will help you get better mileage from your car, save on your fuel costs and help minimize carbon emission. Manufacturers have been using these wheels on electric and hybrid vehicles, but they are now making their ways slowly into the traditional automotive market. The main reason why manufacturers are using them on the traditional vehicles is to help maximize the fuel mileage. They are available in a wide variety to help suit different driving and vehicle needs.

Adaptive resistance
Whenever someone mentions the phrase “autonomous vehicles” what gets in your mind is the world of tomorrow. You can easily visualize safer cruising down highways while waiting work emails or reading for pleasure – instead of watching the highway. Today, adaptive cruise control is saving around 700 million liters of fuel per year and preventing around 1.7 million tons of CO2 emissions. As technology changes, we expect lower carbon dioxide gas emissions to the environment.

Automatic switching of the engine when stopping
An operating vehicle will emit a variety of gases from the tailpipe including CO2, which is the principal greenhouse gas contributing to climatic change. Whenever a vehicle idles for 10 seconds, it will use more fuel and produce more CO2 gas than when restarting the engine. This means that automatic switching of the engine helps in reducing carbon emission to the atmosphere. That particularly applies to diesel vehicles, which produce more carbon dioxide gas per liter.

More efficient combustion
The level of carbon dioxide emission from combustion highly depends on the carbon content of the used fuel. Carbon is completely oxidized during combustion leading to CO2 emission. Through efficiency improvement in vehicle engines, the level of Carbon emission to the environment has reduced by around 40%.

Lower intake and exhaust resistance
Vehicle engines are not 100% combustion efficient and therefore some hard carbon will exit through their exhaust systems naturally. For an engine to attain maximum fuel economy, every individual cylinder should operate at the maximum efficiency. Fuel economy does not depend on the entire engine but on the cylinders operating with the injectors and combustion chambers to achieve maximum level of combustion efficiency.

Fuel Oil Emulsion technology
The fuel oil emulsion (FOE) technology burns more fuel completely and therefore, vehicle use less fuel per mile. Emissions are minimal and the engines run cooler. Therefore, need for maintenance is less. The technology has minimized use of fuel and level of carbon emission to the environment. Vehicle owners are also saving on the fuel cost.
Front-Wheel drive vehicle hybrid system
The wide range of cars available in the United States boast front-wheel drive layout. The drive design has many benefits include great interior room, shorter hoods and greater efficiency due to minimized parasitic drag. The cars offer greater fuel economy and emits less carbon dioxide to the environment.

Wow I had always thought the opposite about the turbo. All makes sense to look after fuel efficiency. Even if you don't care about air pollution everyone has a soft spot for minimizing damages to the hip pocket...
