Ck-4 and fa-4 diesel engine oil clasifications replace cj-4 to tackle emerging engine technology

The diesel engine oil available for your fleet is about to undergo a major change. Gas dryer vs electric dryer operating cost Two new oil categories, CK-4 and FA-4, have been announced by the American Petroleum Institute (API) and will replace the existing CJ-4 heavy-duty engine oil classification. Electricity electricity lyrics You will need to understand the differences between these new oils, since they were developed to meet the diverging needs of protecting existing heavy-duty diesel engines, and providing maximum fuel efficiency for specific new engine designs. Electricity generation in india Their benefits could be different for every user, depending upon the type of equipment and how it is used.

Typically, new engine oil performance standards have emerged every four to five years. 5 gases found in the environment “The CJ-4 standard was first introduced in October of 2006, so it lasted 10 years,” recalls Dan Arcy, global OEM technical manager, Shell Lubricants.

During that time frame, there have been dramatic changes in diesel engine technology, which are placing greater demands on engine oil and necessitated the move to the new categories. Sgas belfast For example, if an engine can run at a higher internal temperature, it can be more efficient and burn less fuel while producing fewer pollutants.

The API claims CK-4 oils will be especially effective at sustaining emissions control system durability where particulate filters and other advanced aftertreatment systems are used. Electricity and magnetism worksheets middle school They are designed to enhance protection against oil oxidation, viscosity loss due to shear and oil aeration, as well as catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties and soot-related viscosity increase.

The high-temperature oxidation stability is the most notable change. K electric jobs 2015 “In all my 27 years of being in the lubricants business, this is the most severe test I have ever seen,” Arcy comments.

“CITGO CITGARD engine oils will have up to 60% better oxidation resistance compared to API CJ-4, which aids in extended service intervals,” says Mark Betner, heavy duty product line manager, CITGO.

The FA-4 category is targeted to on-highway tractors. R gasquet “FA-4 oils are thinner in viscosity and provide a fuel economy benefit,” says Arcy. Gas utility cost “Over the past several years, we have witnessed a transition from 15W-40 toward 10W-30 oils for increased fuel efficiency. Q gastrobar leblon All major OEMs factory fill with a 10W-30 or offer 10W-30 as factory fill today.”

There are no set numbers for how FA-4 oils could impact fuel efficiency, but the move from 15W-40 to 10W-30 provides a clue. Gas stoichiometry practice sheet “Today, going from Shell Rotella 15W-40 to Shell Rotella T5 10W-30, we are able to substantiate a 1.6% fuel economy savings,” says Arcy. U save gas station grants pass “Going from a 15W-40 CK-4 product to a 10W-30 FA-4 or a 5W-30 FA-4 product, I would expect that we will see a number that is greater than that 1.6%.”

A main driver of engine technology is government-mandated regulations. Gas x ultra strength during pregnancy The associated oil technologies must keep up. Gas x directions For instance, CJ-4 oils were a result of the move toward the use of diesel particulate filters (DPFs) and selective catalytic reduction (SCR) to meet Tier 4 emissions standards. Electricity videos for 4th grade New regulations on the horizon are pushing oil demands beyond current CJ-4 requirements.

Stricter regulations to reduce carbon dioxide emissions and improve fuel economy in on-road diesel engines start in 2017. Electricity prices by country “In 2010, the U.S. Gas after eating eggs Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) announced regulations to reduce greenhouse gas (GHG) emissions and mandate fuel economy improvements for medium- and heavy-duty engines and vehicles,” says Shawn Whitacre, senior staff engineer, Chevron. Gas station in spanish “The new regulations would be phased in between 2014 to 2017, imposing different fuel efficiency targets based on the size and weight of vehicle/equipment types.”

“Diesel engine developments over recent years include engine hardware and engine operational changes,” Betner explains. Electricity font “One of the most significant changes to engines includes continuous operation at higher internal temperatures, creating more stress on the engine and engine oil.”

“The Engine Manufacturers Association (EMA) in turn made a request for the API to develop a new commercial engine oil performance category to address engine oil requirements of these new engines,” says Whitacre.

But on-road regulation was not the only factor driving the demand for increased oil performance. K electric bill “Off-highway benefits substantially, and off-highway OEMs played a big role in the development of this category,” Arcy points out.

With the GHG regulations looming, manufacturers were looking for every avenue to increase fuel economy, which led to requests for a lighter viscosity grade oil and friction modifiers.

“It is recognized that engine oil can play a direct role in improving fuel economy through the use of lower viscosity grades,” notes Whitacre. Gas 85 vs 87 “The EMA request included a proposal to introduce a subcategory with lower viscosity than allowed by previous performance categories.”

The demand for a lighter viscosity oil for improved fuel economy resulted in the split from the traditional single heavy-duty oil classification. Electricity inside human body Consequently, the CK-4 and FA-4 API categories will be two distinct oils that can’t necessarily be substituted for one another.

Designed for both the over-the-road and heavy equipment markets, CK-4 oil will be a direct replacement for CJ-4 products. Electricity invented or discovered “The primary difference in the two categories of heavy-duty oil is with backwards compatibility,” says Whitacre. Gas pressure definition chemistry “API CK-4 oils will support virtually all high-speed, four-stroke cycle diesel engines, including older engines that were using CJ-4, as well as new engines that are currently being developed. Gas 2016 Use of API FA-4 oils will be OEM dependent and may not be suitable for use in older diesel engines. V gashi This category will focus on the next generation of diesel engines that are currently in development to deliver greater fuel efficiency.”

Because CK-4 category engine oils are backwards compatible with CJ-4 and API CI-4 PLUS oils, and meet the needs of new and older engines in both on- and off-highway applications, they are better suited for mixed fleets looking to utilize a single engine oil. Gas 6 weeks pregnant “The improvements will deliver additional benefits to customers by enhancing engine durability and extending oil drain intervals,” says Whitacre.
