DECREASE CARBON BUILD UP, INCREASE FUEL ECONOMY, PROTECT YOUR DIESEL ENGINE
Diesel Engine Changes
The new Ford diesel engines are not your father’s diesel. For years consumers were spoiled by diesel engines that were driven hard, put away wet, and probably not serviced as frequently as we would like to admit. In recent years Government Emissions regulations have tightened and to a large degree dictated the evolution of the new diesel motors.
The most recent government standards call for the virtual elimination of NOx (greenhouse gasses) and particulate matter (soot or smoke) from the exhaust. In order to conform to these strict rules, and still provide the power and performance that you have grown to expect from a Power Stroke, Ford has implemented several substantial design changes.
NOx are created by the extremely high temperatures reached during the combustion cycle. The most popular way to reduce the output of NOx is to mix fresh air with recycled exhaust gases by means of an Exhaust Gas Recirculation System (EGR). Adding an inert exhaust gas into the cylinder displaces fresh air which cools down the cylinder’s temperature and thus reduces the NOx production.
Particulate matter is being addressed with new technologies as well. Manufactures have incorporated a variety of advanced injection systems and exhaust after-treatment designs that filter particles prior to their release into the atmosphere. The most current and widely used technologies are the Diesel Oxidation Catalyst (DOC) and a Diesel Particulate Filter (DPF). After leaving the turbocharger, the exhaust flows through the DPF were the particulates are trapped so they can keep from being released into the atmosphere. Eventually the DPF will become filled with particles and will need to be cleaned. The vehicle will automatically initiate an exhaust cleaning procedure where the engines exhaust stream is mixed with fuel that creates temperatures high enough to turn the matter into ash.
Government regulations have not stopped at the diesel engine. The composition of Diesel Fuel itself has been forced to change. Up until 2006 most diesel fuel was Low Sulfur (LSD – 500ppm), but today diesel fuel is regulated to be Ultra Low Sulfur (ULSD – 15ppm). The downside is that Ultra Low Sulfur Fuel holds 1.5 percent less energy than LSD thus decreasing the fuel efficiency of your diesel.
Cetane Ratings, Carbon build-up, and Fuel Economy
Fuel quality is a critical factor in the fuel economy and the durability of your diesel engine. Fuel quality and its centane rating is a major determinate in the amount of particulates generated by the combustion process. The cetane rating of diesel fuel is basically the ability of the fuel to combust. The higher the cetane rating the better the combustion process will be. Centane rating is similar to octane ratings for gasoline. Ford recommends and designs their engines on a minimum of 45 centane level.
Unlike octane there is no regulation or posting of centane ratings at filling stations. Surveys have shown vast inconsistencies in cetane ratings between manufacturers and filling stations, so you can’t be certain what you are pumping into your vehicle. Since 1966 when diesel fuel averaged a cetane rating of 50, the America average centane rating of diesel fuel has fallen to 40, 5 points lower than Ford’s minimum recommendation.
The main problem with this low cetane rated diesel fuel is the inefficient combustion cycle that results. Less efficient combustion cycles cause numerous problems, the most obvious being poorer performance and decreased fuel economy. A less visible, and perhaps more detrimental, effect is the particulate build up inside the engine. As stated previously, the new EGR systems in diesel engines use cooled exhaust gas to lower combustion chamber temperatures. When the exhaust gas is contaminated with particulate matter created through inefficient combustion, that particulate ends up right back inside the engine reeking havoc on EGR valves, turbos, and intake manifolds.
Using Fuel additive like Ford Power Stroke Diesel Centane Booster & Performance Improver can increase fuel centane levels significantly and reduce these detrimental particulates – Better combustion, Better fuel economy, less expensive carbon-related engine repairs.
