DBKL gives B10 biodiesel the thumbs up, happy to continue testing.POSTED BY Yamin Vong ON 26 July 2017
More popularly known as DBKL, Kuala Lumpur City Hall has clocked up about three million kilometres with the B10 palm methyl ester biodiesel, since commencing trials with the Malaysian Palm Oil Board (MPOB) in January 2014.
“We have dedicated 50 vehicles for the B10 biodiesel trials with MPOB and we are happy to continue trials with them,” said DBKL’s Mechanical and Electrical Engineering Department engineer Muhammad Alif Muhammad Noor.
“DBKL’s policy is for Kuala Lumpur to be a green city and we support MPOB’s initiative to promote biodiesel as a sustainable and green fuel,” he added at a media briefing last month.
“We have 2,040 vehicles. Half of them currently use diesel. We chose the test fleet based on the vehicle’s age as well as mileage. Obviously, we don’t want the void our engine warranty so the youngest test vehicle is a three-year-old pick-up while the oldest test vehicle is a 17-year-old truck.”
DBKL was among the first third party consumers of B10 biodiesel in Malaysia as the fuel is not available commercially.
The test vehicles obtain their supply of B10 biodiesel from two 16,000-litre skid tanks at DBKL. Most of these vehicles have accumulated an average mileage of between 60,000 to 70,000km, with one of its five-ton lorries recording more than 200,000km. The vehicles are Euro 2 and Euro 3 compliant.
A Nissan Navara pick-up truck and a Nissan five-ton lorry are due for a more detailed inspection that includes an engine tear down, which is expected to be jointly conducted by MPOB, Nissan Japan and the local franchise holder for Nissan in Malaysia, Tan Chong Motor Holdings.
“What is most obvious is that B10 biodiesel has reduced exhaust emissions and lower toxicity levels compared to mineral oil-derived diesel,” said Alif, adding that DBKL is seriously considering extending the use of B10 biodiesel to its entire fleet of 2,040 vehicles.
Notably, the Department of Environment (DoE) that stipulates vehicles should not exceed 50% Hartridge Smoke Units (HSU), concluded DBKL’s test vehicles did not exceed 2.8% HSU.
“The smoke test conducted by the DoE showed that our Nissan UD LKA produced only 2.8% HSU while our Navara pick-up truck produced 2.7% HSU,” said Alif.
