What is the difference between bluetec and cdi

All Bluetec vehicles use Diesel exhaust fluid, also known as AdBlue. It is stored in an external tank, and it would freeze in cold weather. To prevent this, DEF tank is equipped with an electric heater which can burn out. While the outside temperatures are not very low, this will not affect engine performance. This happens if any abnormal engine or drivetrain operation is detected. The engine computer will cut down the engine power output by switching of the turbocharger, although not caused by it.

In extreme cases, it will even limit the gear selection to one gear and reverse. This is done to prevent any damage to your engine, but also to force you to fix the problem without a delay. Usual causes are faulty EGR valve, swirl flap motor, turbocharger actuator or boost leaks.

Make sure you have traced down the actual cause of the problem before changing anything. Oil leaking from oil cooler is a problem that affects present V6 diesel engines. This is a common oil leak source on all Mercedes engines. It is caused by hardened oil cooler gaskets.

Good news is that oil cooler itself can be reused. In addition, there are upgraded seals available. This means that once replaced, seals will not leak anymore. Bad news is that the oil cooler is located between engine heads, in the depth of the engine Vee. This means that intake manifold, turbocharger and a lot more must be removed. This makes it expensive repair if you take it to the garage. However, you can save a lot of money if do it yourself.

Glow plugs are an essential component for a cold start of every diesel engines. These are, in essence, a strong electrical heaters. Future Truck Mercedes-Benz Urban eTruck. Special Purpose Vehicles. Mercedes-Benz Special Trucks. Heavy-duty class. Middle model range. Design concept.

The introduction of BlueTEC in the passenger car in marks the beginning of a new era in Mercedes-Benz diesel-powered cars. The engineers of the Stuttgart-based brand initially developed this visionary emission control system for commercial vehicles, introducing it to the market in BlueTec it is spelled differently if referring to cars or commercial vehicles immediately set standards for the reduction of the pollutants in diesel exhaust gas, which promptly was reflected in success on the market: in February the 10,th BlueTec truck with Euro 5 engine was delivered to a customer.

And in more than , vehicles with BlueTec were in operation — with a great many more to come. This is a good foundation for developing BlueTEC for diesel passenger cars.

Evolution of the compression-ignition engine in the car. Considering the history of innovation of the diesel passenger car at Mercedes-Benz, the step to incorporate BlueTEC into present-day cars is only logical: the Stuttgart brand built the first diesel passenger car in And in the C II with diesel engine set standards on its record-breaking run in Nardo.

The history of diesel technology is punctuated again and again by such major innovations — especially owing to the initiatives of Mercedes-Benz. Since about the pace of technological development has picked up very strongly. And this is why in BlueTEC became the latest standard of this diesel evolution.

Where the development of the compression-ignition engine into a clean and powerful drive for future automobiles can take us is shown by studies like the S-Class S BlueTEC Hybrid, presented at the Frankfurt International Motor Show in , which combines the low-emission diesel with an electric motor.

The diesel engine switches itself off whenever it is not required. The combined output of this S-Class car is kW hp ; the combined torque is as high as Newton metres. Fuel consumption New European Driving Cycle is as low as 7.

The study made this very clear: at Mercedes-Benz the diesel has great potential as a high-tech drive of the future.

But for the first, in the clean Mercedes-Benz BlueTec commercial vehicles were the trendsetters for the car sector, as the highly innovative system for reducing nitrogen oxides NOX and other emissions also lends itself to application in passenger cars: BlueTEC reduces nitrogen oxides to such an extent that the toughest emission limits worldwide can be met.

In early Mercedes-Benz then presented BlueTEC for passenger cars as a ready-for-production package consisting of several components. The extensive optimisation of the engines and the combustion processes taking place inside them constitutes the basis of this package. With solutions like multi-hole injection nozzles, the use of the latest generation of CDI technology and other measures, the raw emissions are cut to an extremely low level. This is where the emission control system with an oxidising catalytic converter for hydrocarbons and carbon monoxide and a particulate filter comes in.

The final stage is nitrogen oxide reduction by the BlueTEC component proper. BlueTEC is the designation for a highly efficient method of minimizing nitrogen oxide emissions already used in commercial vehicles.

This long-distance trip involving a total of 36 Mercedes-Benz E-Class Saloons recalled an adventurous long-distance journey organised in , but which went in the opposite direction, from Beijing to Paris. One reason, of course, is the growing demand for economical and at the same time clean cars in that country, caused by rising fuel prices. Modern diesel-engined cars which, in West Europe, account for more than half of new registrations annually, were unable to develop their full potential in the USA due to the excessively high sulphur content in the fuel until then.

This changed at the end of thanks to the nation-wide introduction of clean diesel fuel with a sulphur content of just 15 ppm 15 cubic centimetres of pollutant per cubic metre of fuel. With this innovative diesel technology, Mercedes-Benz is also able to remain below the strictest globally applicable limits where nitrogen oxide emissions are concerned.

Hence, all the preconditions for the breakthrough of modern diesel technology in the USA are fulfilled. It easily is the cleanest diesel in its class and fully meets the requirements of the Euro 5 exhaust emission standards.

The high-performance V8 diesel engine develops kW hp , has a torque of Newton metres and is expected to have a fuel consumption of just 9. These self-assured looks are enhanced by flared wheel arches, representative inch wheels and lateral floorboards.

On this occasion, Dr. With 35 miles per gallon or 6. Scientific American named BlueTEC as one of the 50 groundbreaking innovations in science and technology of the year My car is badged both Bluetec and Blue Efficiency. The Bluetec refers to the engine as explaned above and the Blue Efficiency to the aerodynamic design with lower weight materials etc to reduce fuel consumption.

Or so I was told by the dealer. Craiglxviii Senior Member. Bluetec is Euro6d which is the latest selective catalyst reactant tech required in global Emissions standards control. You must log in or register to reply here. AIB understand your special Mercedes deserves a special insurance policy.
