In the vast majority of modern diesel engines there is a sophisticated fuel injection system and a great number of exhaust aftertreatment ancillaries that are attempting to sort the symptoms of incomplete combustion but not treating the actual cause.
Briefly put the lack of optimum fuel economy and the very real air quality and emissions problems are all down to the same thing – incomplete combustion of diesel fuel. To some extent the drop in fuel quality due to the legal requirement for EN590 white diesel to contain 7.25% FAME biodiesel – a bad technical decision but a good greenwash one – is also not helping.
Government imposed low emissions zones (LEZ) in city centres are because of air quality issues from PM emissions, if fuel is better burned as with our pistons, the emissions don’t happen in the first place!
Let’s have a look at the exhaust systems that are present on modern vehicles and thus scratch the surface of why they are unreliable and costly to fix and my well have actually demolished the value of second hand trucks – what do they consist of? There are 4 parts as below:
EGR – Exhaust Gas Recirculation
This system does what it says sending dirty carbon-ridden air from exhaust back round to the cylinders a second time, it reduces emissions but cokes up badly due to high particulate matter (soot/smoke) and does nothing to help combustion.
DOC – Diesel Oxidation Catalyst
This is generally a precious metals catalyst to assist in cutting carbon monoxide and nitrous oxides, there is a side that it is valuable for thieves.
SCR – Selective Catalytic Reduction
This is the mechanism that uses AdBlue urea solution to react with the exhaust stream and turn NOx into harmless nitrogen, while clever, there is plenty to go wrong with associated high costs and the cost of DEF itself.
AdBlue doser problems are a large factor in the low prices for older trucks.
DPF – Diesel Particulate Filters
These are a ceramic honeycomb component that filters particulate matter out of the exhaust plume – they require frequent regenerations to keep unblocked which is done by burning off with fuel (at your cost!).
Cleaning DPFs and repairing their associated problems has nor become a multi-million pound industry in itself which is hugely costly for you.
The Answer – Opti Combustion Pistons
The radically simple answer and partial cure to diesel emissions and lack of ideal economy lies in having your diesel engine rebuilt with these remarkable pistons.
Utilising 6 significant modifications around the crown geometry, gapless piston rings, abradable skirt coatings and ceramic top coating, these pistons provide ideal conditions for combustion that solves many of the problems at source instead of by aftertreatment.
Typical diesel engine efficiency upgrades resulting from this technology include:
- Greatly cut emissions of pollutants like PM, NOx, and HC, potentially even without DEF fluid (AdBlue) for the SCR catalyst.
- Around 15 to 20% better fuel economy in diesel engines.
- Smoother power and extra torque with earlier turbo engagement.
- Doubles the life of engine oil due to a cut in blowby of carbon into the sump/crankcase.
Do you have an older fleet of trucks, cranes, excavators, or locomotives? Applying this rebuild can jerk older but perfectly serviceable vehicles into excellent performers that are in advance of Euro 6 performance with great productivity boosts and sustainable operation.
