Our recommendations in various categories are based not only on expert knowledge but also real-world customer reviews. If you don't do this, he added, 'very, very bad things can happen.' Manufacturers provide specific information about the plugs you should use, part numbers that can easily be cross-referenced to find compatible plugs from different manufacturers if you don't feel like purchasing an OEM spark plug.ĭemystifying things, this guide highlights some of the best spark plugs on the market today and delves into related terminology. Hans Lipp, director of ignition application engineering at DRiV Motorparts, a division of Tenneco, summed it up best, ' the spark plug that you put into your engine is actually recommended for this specific engine,' especially the heat range. There are different electrode materials and plug lengths, heat ranges vary based on application and some spark plugs are intended strictly for turbocharged or supercharged engines.īut what's the best kind of spark plug to buy if it's time to replace them in your ride? Well, this is actually an easy question to answer. Beyond that, there's a dizzying array of spark plugs on the market, with specific designs for everything from lawnmowers to race cars. On the surface, these cylindrical, threaded components seem simple, but there's an incredible amount of engineering that goes into each one. The business end of an ignition system is the humble spark plug.

These parts join forces to ignite the delicately balanced mixture of air and fuel in each cylinder, which is ultimately what sends you zooming on down the road.

Spark plugs, coil packs and high-tension leads are your vehicle's unsung under-the-hood heroes as they play one of the most important roles in the four-stroke combustion cycle. The variety of catalytic reactions for which these metals have been investigated is extremely wide, and the collection of this considerable amount of data into one carefully arranged volume will unquestionably provide a most useful source of information for chemists and chemical engineers concerned with reactions in which one or other of these metals may provide the most suitable catalyst.Are you someone who drives a gas-powered car? Has there ever been a time when you've thought about your car's ignition system? If your answer is no, don't worry - you are definitely not alone. They are arranged in sections dealing respectively with the hydrogenation of organic compounds, other reactions of organic compounds, reactions with inorganic compounds, and catalyst properties. Rea and Marguerite Bebbington of the company’s Development and Research Division, the bibliography contains more than three hundred abstracts of papers and patent specifications, covering the period from 1881 to mid-1959. But scattered throughout the world’s scientific literature are quite a number of records of research carried out with one or other of these metals as catalysts in many different types of reactions.Īn admirable survey of this literature has now been prepared and published by the International Nickel Company Inc., New York, as an Annotated Bibliography on Ruthenium, Rhodium and Iridium as Catalysts. The catalytic properties of the other members of the platinum group of metals are by no means so fully appreciated, nor are they employed for this purpose to anything like the same extent. The literature on both platinum and palladium as catalysts is very extensive, and these two metals are widely employed in a variety of reactions on a commercial scale.
