When it comes to choosing which fuel to use to power a vehicle, a number of factors come into play. In the classic conundrum of diesel or gasoline for petroleum powered vehicles, there has always been a faustian bargain to be made between efficiency and cleanliness. Petroleum releases more of its energy when burned under higher pressure and at higher temperatures—this is the mode of action of Diesel, which is chosen for its higher efficiency over gasoline. However, this deeper burn of diesel, in which more of its energy is released, also releases much higher levels of emissions, some toxic, and that tell-tale soot that fills the streets when diesel is utilized by a high percentage of vehicles.

The debate over diesel and gasoline still rages on, with incremental improvements by both kinds of engines—gasoline engines becoming more efficient and diesel becoming cleaner—tipping the debate in either direction periodically. The problem, of course, is that these improvements are indeed only incremental, and the inherent problems with both kinds of engines persist. One company in Iran, Pars Mechanic Khavaremiyaneh, commonly referred to by its initials PMK, has dedicated itself to doing away with this debate altogether. There is, the company contends, a better alternative, and it has the technology to make it the only sensible choice of fuel for automobiles and industrial vehicles in Iran: compressed natural gas.

The automobile has long served as a readymade symbol of human progress, and we can see in the way a particular car or truck is designed a reflection of the values and priorities of the society that produces it. In 1950’s America, the automobile grew in size, power, and complexity, serving as a symbol of American optimism in the post-war boom. In southern Europe, cars are small, nimble, and cheap, seen more as a check on convenience than a boon to it in cities that were built hundreds of years ago. In Germany, cars are seen as the technical spearhead of engineering possibilities, built to run with muscular precision and smoothness at high speeds on the autobahns.

So what then, would PMK’s mission to spread the use of compressed natural gas, or CNG as it is most commonly called, say about modern day Iran? Natural gas is, after all, already in widespread use for generating electricity, and for powering in-home heating and cooking implements across the globe. Its use as a fuel source for vehicles is spreading as well, and this is thanks to its myriad advantages over other fuel sources.

First of all, CNG burns cleaner than either gasoline or diesel, releasing 20-29% less CO2 for an equivalent amount of power, and its emissions are 100% non-toxic, with lower particulate content as well, so no catalytic conversion is necessary. Generally speaking, CNG is more efficient than petroleum, wasting less fuel when burned. It is considered safer than gasoline, as CNG has a narrow range of flammability in both temperature and concentrations when mixed with air. And if it does become inflamed, it burns at a lower temperature than gas. CNG powered vehicles also experience less wear and tear on their engines, reducing maintenance costs. And speaking of costs, natural gas is much, much cheaper than gasoline in most places around the world, and it is a natural choice to power Iran’s vehicles, as the country is home to the second most extensive reserves of natural gas in the entire world, only coming behind the massive country of Russia in that regard.

It’s no wonder that, in many countries around the world, CNG is the fuel of choice for powering large fleets that are assembled all at once. The cost savings and lower emissions alone are enough to cause many of the world’s largest cities to power their immense fleets of public busses with natural gas, these same benefits also compel many of the largest airports around the world to power the trucks, cars, and carts that zip around their tarmacs with CNG as well. It is widely recognized that there are enormous benefits of utilizing CNG, especially when implemented at scale.

The arguments against the use of CNG in vehicles are generally centered around feasibility and technical concerns. CNG must be stored in high-pressure cylinders, a major disadvantage over the relative ease and flexibility in storing gasoline, which can be put in a tank of any size or shape. It is also generally considered extremely difficult to dispense, as it requires large amounts of energy to maintain the correct pressure from tank to tank. This is where Tehran-based company PMK comes in.

Tasked with the all important mission of making CNG not only accessible to large institutions and businesses, but to individual drivers and small enterprises as well, PMK has made available new CNG dispensers that greatly simplify the process of refilling cars and trucks with the fuel. PMK also distributes all of the implements and tools needed to build-out and maintain a new, state-of-the-art CNG filling station. From calibrators to fine-tune dispensers, leakage detectors for safety, to all the valves and adapters needed to make connections, PMK has partnered with the leaders in the field to bring these tools to Iran.

With PMK’s products at the ready, there remain few obstacles towards further adoption of CNG, which in Iran especially will be a major boon to productivity and efficiency in all corners of the economy. With highly efficient warehousing platforms, distribution activities, and a high-value proposition to consumers, PMK ensures its quality with a customer-oriented approach to business, a policy of constantly updated training and education for its employees, and a vision towards transforming Iran into one of the countries with the most progressive vehicle technologies in the world.

For its quality as an organization, for the importance of its mission to the national economy, and for making the widespread adoption of CNG a feasible and practical choice for its customers with cutting-edge technology, Pars Mechanic Khavaremiyaneh (PMK) has been selected to receive the internationally prestigious 2016 BID Quality Award.
