It has almost been eight years since Petronas launched its Dynamic Diesel Euro 5 with Professional-Drive, and as you’d anticipate, there have been revisions to its formulation since its Euro 5 iteration was launched on the finish of 2017, particularly when it comes to its additive packages.
As to what number of, there have been a couple of, in accordance with Petronas gas know-how supervisor Mohamad Hafiz Abd Aziz. “Growth of the components is finished each two years. We don’t shout about it, however we alter it each two years,” he mentioned.
The newest replace to the gas has led to vital good points, sufficient that the corporate can shout about it in quantifiable phrases, one thing it often by no means does, with as much as a 20% enchancment in gas financial system and a cleanliness effectivity of 99% being the main factors. Moreover, there’s additionally an enchancment in engine smoothness and energy, encapsulated in its newest catchphrase, Pikap Cekap ke Destinasi.
These new features of the gas had been highlighted throughout a particular Dynamic Journeys powered by Dynamic Diesel collection engagement with the media, which concerned a web site go to to its subsidiary Malaysian Refining Firm’s (MRCSB) Melaka Power Park facility, situated in Sungai Udang, Melaka.
Right here, the science behind how the enhancements had been achieved was detailed. “In creating fuels, we do numerous testing, and these aren’t our personal in-house ones, however based mostly on business normal take a look at protocols. Worldwide, after we are creating the fuels, there are key necessities that we have to fulfill. Certainly one of these is the cleansing efficiency,” Mohamad Hafiz mentioned.
“The 2 issues that we now have improved within the newest iteration of Dynamic Diesel is the inclusion of dual-detergent chemistry and a proprietary combustion improver,” he mentioned.
Whereas maintaining key parts – similar to injectors – clear is significant, he said that this must be completed each in and out. He mentioned that a lot of the concentrate on maintaining the diesel system clear often revolved across the injector hose, however this isn’t sufficient, significantly as regards to frequent rail methods.
“Addressing the everyday injector hose is one component. In fact, if there’s numerous carbon within the hose, you can’t spray the gas. However one factor that folks are inclined to neglect when creating a gas is the within of the injectors. If there’s a carbon build-up on the injectors, the injectors will get clogged, which is a matter significantly while you’re utilizing frequent rail,” he mentioned.
“That’s why we now have dual-detergent chemistry to deal with each crucial components of the diesel engine system, not simply the injector hoses but additionally contained in the injectors,” he added. The additive package deal additionally offers a protecting layer on the metallic floor to stop the build-up of latest carbon deposits.
Mohamad Hafiz mentioned the cleansing efficiency of its newest additive package deal is mirrored within the gas’s ranking in Inside Diesel Injector Deposits (IDID) assessments carried out by the corporate.
“It reveals in our ranking, which is 30. That is the utmost ranking that we will get based mostly on the take a look at, which is a really extreme take a look at. It’s not based mostly on the one hour or two hours that you just see in a typical lab take a look at, however includes an engine take a look at mattress, and it’ll run 30 hours, 32 hours or 60 hours to see the affect on the components that we now have,” he defined.
“When you could have superb cleanliness at your injector hose and your injector needles, you’ll be capable to ship superb gas financial system. Moreover, we now have a combustion improver know-how, one that isn’t obtainable to others as a result of it’s proprietary, to reinforce the effectivity of the gas combustion. Each single drop of gas that we burn has to ship energy that we’d like. We don’t waste any gas,” he said.
The good points in gas financial system are vital, with Petronas placing numbers right down to mirror its confidence within the gas. “Within the lab, the brand new Dynamic Diesel formulation reveals as much as 20% in gas financial system enchancment, which is equal to about 222 km further per tank of gas. Which means to say, you possibly can go additional, as much as Ipoh (from KL),” he mentioned.
In fact, choosing the appropriate chemistries that work within the lab or an engine take a look at mattress within the engine take a look at is one factor, however evaluating the gas in actual world circumstances with precise autos was essential to validate the findings. “We needed to ensure that no matter that we developed within the lab and examined on the engine take a look at mattress was achievable additionally in the actual world,” he mentioned.
The corporate trialled the gas on a number of sorts of car model fashions, and mentioned gas financial system good points had been registered on all evaluators, with one attaining as excessive as a 36% enchancment in gas financial system. 4 of the opposite eight take a look at mules additionally recorded greater than a 20% enchancment, tying in with the lab outcomes.
He additionally highlighted different areas of enchancment led to by the gas. “Moreover gas consumption, one other factor that individuals are searching for is acceleration and energy efficiency. As a result of each single drop of gas that we burn is ready to ship further energy on account of the combustion improver, we bought as much as 5% higher acceleration energy and as much as 3% energy acquire on the car assessments that we carried out,” he mentioned.
On the take a look at mattress, he mentioned it was proven that the dual-detergent package deal in Dynamic Diesel was capable of clear a grimy engine and restore the ability as much as 99% inside eight hours, with the proprietary combustion improver additionally offering a further energy acquire of 1% to 2%.
Throughout the take a look at cycle, the gas additionally needed to minimise energy loss to lower than 2% for a time frame. “That is as per requirement by business requirements, minimising energy loss to lower than 2% for about 10 to 22 hours. This can be a normal take a look at protocol to outline the cleanliness and the effectivity of the gas to make sure that the cleanliness of the engine is maintained,” he defined.
As is was earlier than, Petronas Dynamic Diesel Euro 5 continues to have a excessive cetane quantity (round 55 and above), which leads to a shorter ignition delay, making for simpler begins and smoother engine efficiency. Mohamad Hafiz says it hasn’t been essential to make use of cetane components to enhance the ranking, as a result of biodiesel already aids in that course of naturally.
“We don’t have to put in a cetane improver to our additive package deal, as a result of the biodiesel that we’re utilizing now, 7%, 10%, and in sure circumstances, even 20%, will enhance the cetane ranking above 55. No matter you get at our stations, it’s greater than 55,” he mentioned.
Mohamad Hafiz ended his presentation by saying that there isn’t any want for aftermarket gas components if customers are utilizing Petronas fuels. “What’s inside our fuels are customised, so we now have extra lively elements as in comparison with these available in the market, and these present the same perform, if not higher,” he mentioned.
The presentation was concluded with a fast tour round Melaka Power Park, which contributes to round 60% of Peninsular Malaysia’s petroleum product demand. Boasting a every day manufacturing fee of 300,000 barrels, the ability is supplied with a number of specialised processing items designed with the flexibleness to deal with numerous crude oils from candy crudes to heavier imported crude oils. The newest addition to the power park, the Delima plant, was launched in 2021, and produces Euro 5 diesel.
