Total Supports Buses and HGVs on Low Emission Journeys

Total Supports Buses and HGVs on Low Emission Journeys

In a bid to tackle toxic air pollution, the world’s first ultra low emission zone (ULEZ) will come into force in central London from April 2019. Meanwhile, Clean Air Zones (CAZ) will come into effect in five cities by 2020, with other towns and cities expected to follow suit.

The details of the proposed Clean Air Zones in some cities including Southampton are still being finalised but some cities, such as Leeds, have confirmed they will introduce a chargeable CAZ, where buses and HGVs that fail to meet the required emissions standards will be charged a daily fee to enter it.

HGVs and urban buses already have to work incredibly hard but in order to be compliant with the upcoming legislative changes operators are investing in updating their fleets to the latest Euro VI engines. These offer a significant reduction in the most harmful pollutants, including emissions of particulate matter, nitrogen oxides, unburnt hydrocarbons, carbon dioxide and carbon monoxide.

With the challenge to reduce emissions combined with advancements in engine technology and the roll-out of Euro VI engines, lubricants manufacturer Total Lubricants is already supporting fleets in their drive to become cleaner, greener, and more efficient.

Lubricants

Total’s RUBIA 9900 FE 5W-30 grade has been developed for Euro VI but is suitable for lubricating all types of diesel engines, including Euro V and previous, fitted with or without post-treatment systems such as exhaust gas recirculation (EGR), selective catalytic reduction (SCR) or diesel particulate filter (DPF). Its backwards compatibility with previous Euro standards enables coverage for mixed fleets by a minimal number of products.

The advanced low-SAPS (low sulphated ash, phosphorus and sulphur) formulation of RUBIA 9900 FE 5W-30 helps prevent the clogging of the DPF and extends post-treatment durability.

Additives

TOTAL EXCELLIUM is a diesel fuel additive for buses and commercial fleets which keeps fuel injectors clean and improves clean burn inside the engine, providing up to a 5% reduction in fuel consumption.

Across 10,500 miles, EXCELLIUM also delivers a reduction in CO2 emissions of up to 4.2%, while carbon monoxide emissions are reduced by 32%, unburnt hydrocarbons by 55%, nitrogen oxides by 21% and particulates by 16%.

Many buses also require AdBlue®, a fluid that is added to the exhaust system and chemically reacts to convert harmful NOx emissions to innocuous nitrogen (N2).

Oil & coolant analysis

Using oil analysis can help bus fleet operators see how engines are performing, check fuel injectors are working properly, and ensure oil viscosity is in the right range as this is vital to achieving optimum engine efficiency and emissions control.

If soot is absorbed by the engine oil, it can thicken it which can lead to greater wear. Oil analysis such as Total ANAC (Analysis Compared) can also highlight whether the oil needs changing, or if its life can be extended.

Coolant analysis should also be carried out to ensure the concentration of the coolant is correct, and to ensure it doesn’t overheat in summer or freeze in winter.

Coolants

Coolants containing organic acid technology (OAT) offer maximum cooling of bus engines equipped with stop-start technology, designed to reduce exhaust fumes while loading and unloading passengers.

TOTAL COOLELF AUTO SUPRA -37°C is a cooling liquid that can be used in all cooling systems of combustion engines in buses and HGVs, as well as other vehicles.

Servicing

Regular servicing including changing the oil and oil filter when necessary and checking fuel injectors as well as brakes, should be carried out. Air filters, which prevent dust particles getting into the engine and reduce wear should also be changed regularly.
