Volvo Diesel Engine More Powerful and Save Money?

Gothenburg, Info Berita - In Europe, diesel engines are now to be excellent. Almost all producers, from city cars to luxury, offering a diesel product. The reason, the modern diesel engine technology with "common rail" is more friendly to the environment, more efficient fuel consumption, engine sound which is no longer harsh and more subtle vibration. 


In addition, for treatment, not too complicated so that more practical and economical. Hence, more and more manufacturers to develop diesel engines with better capabilities.
One European manufacturer is aggressively develop a diesel engine is a Volvo. Last Swedish carmaker now owned by Geely, China, modify to increase the working capacity of the diesel engine used for the V70, XC70 and S60, the cylinder D5 engine, 5-cylinder turbo diesel and and D3.
Piezo-electric injectors For the D5 engine, improved ability to produce power and torque from 205PS/420Nm into PS and 440 Nm 215. Simultaneously the more economical fuel consumption to 8 percent.
With this new engine, the fuel consumption of the Volvo S80 is fitted with a manual transmission system start / stop system, the fuel consumption (combined) - based on the European test standard - 4.9 literl/100 km or 20.4 km / liter.
Diejelaskan Similarly, if a better driving techniques, will make the fuel consumption and lower pollution. To this Vovo develop certain parts of the machine, with a target of decreasing barriers geseknya.
"Actually, the development in some parts of the machine that performed at the same time making the car more stable steered.Operational costs are also cheap / It took a while to determine and fix the small details for the machine work more efficiently, "says Derek Crabb, Vice President of Powertrain Engineering Volvo Cars.
Sequential Turbo Before the developed again, D5 engine is considered as the best diesel engine in its class. Because this engine uses a twin-turbo technology, sequential (consecutive), glow plugs and fuel injectors ceramic piezo-electric.
New features are developed in a twin-turbo engine is turbocharged with two different sizes, working in tandem to increase the power in the range of engine speed is greater. As a result, the engine became more responsive and powerful and more stable at high rotation speed up. Piezo electric injector technology makes the distribution of fuel into the combustion chamber semakit accurate.
Meanwhile D3 engine that produces 183 PS power and 400 Nm of torque Vovlo introduced in S60 and V60 in 2010 essentially the same as D5. Just a shorter step so that the capacity down to 2.0 liters.
Both engines use the same injector, namely piezo-electric. With accuracy and high working pressure, the injector is working more effectively to produce combustion. Further, the diesel-engined car steadily accelerated at various speeds and engine putarn.
Other factors that also make it more powerful diesel engine, urbocharger used is the type of geometry that can change the alias VGT (variable geometry turbocharger). Angle leaf blade turbo or turbine-sudunya the changes according to engine speed or the pressure of exhaust gases expelled by the engine.
D3 engine power and torque remained unchanged. Nevertheless, the ability of this engine makes the car more comfortable to use it steered.
"Modern diesel engines, torque is greater than power. With a big torque, acceleration over short distances is better than gasoline engines, "explained Derek Crab. source: kompas.com
