The new Volvo engine meets the Tier 4i D11 emission criteria

The construction of devices Volvo new D11 engine has been the level 4 certification EPA emissions (the environment al Protection Agency). Engines that belong to the it w, hin, 175 to 750 hp class are 1 January 2011, emissions-Tier 4i and regulations bind that reduces diesel particulate emissions requires a radical, which must be reduced by 90%, and it, rogen oxide, which is reduced by 50%.

Now certified by the EPA, the new Volvo D11-engine is equipped with a it h, w, V-ACT or Volvo Advanced combustion technology, which features work very high pressure fuel injectors as well as the variable in the supercooled EGR (exhaust gas recirculation) systems. Turbocharger travel, where s is the VGT (variable geometry Turbo), and the exhaust after-treatment is integrated with and use thermal regenerator and it ive sens of the particulate filter.

John Bartz, Vice President of product quality assurance and devices Volvo construction in North America, said:

Volvo devices meets the new rd standa-s readjustment engineer and continuing to develop the highest level of the engines se y qual and it reliabil y and w it h, maximum performance and it y productiv achievements in the market today.

Selections from the results of the D11 advanced engineer-ing is one it w h Volvo Powertrain, which leads to efficient combustion efficiency, which in turn leads to a higher power se y capac, fuel consumption, reduce emissions, and other aspects of the increased cost-efficiency.

Volvo has a wealth of experience in the field of engine solutions, which satisfy the various pieces of legislation, such as the EPA already implemented such technology, their Volvo trucks row row w it h, EPA, highway regulations 2007. Off-highway-solution has been tested on millions of hours and similar conversion may soon be ready for vehicles, such as the backhoe loaders, they can compete in a classic JCB 3cx sale.

The new engine has engineer ed very, w it (h), electronic control s and V of the ACT control system connects, the maximum torque of the engine and it y qual. EGR (exhaust gas recirculation) system for production 's reduce, it significantly, rogen EO easily meet the 50% discount on level 4 of the guidelines required by the State-of-the-art options. It makes this recirculation combustion, thus reducing the Chamber of involved in the oxygen level. This in turn reduces the temperature of the light is on, and this prevents the formation of NOx are significant. The system is the sulphur content of fuel, it is possible to use very. Level 4, the second requirement is huge reductions in particulate matter. The new Volvo exhaust treatment system after catching particles of knowledge applied to oxidized particles, specialised in the filter or renewed, which removes them.

Ultra Low sulfur diesel is also determined by the level of 4 options it to use and includes 15 ppm sulfur, a huge relief to 500 ppm.

Sop, the level of engineering histicate ing characterised by new D11 level 4 compliant engine, due to the high level of engine management (EMS) was necessary, and this is exactly what has happened. The EGF control is an electronic system that rd EICAR.COO inates complex re-the circulations of the Chair.

Bartz says:

Recently EPA certified Volvo engine dramatically demonstrated (begun in 1893), engine technology, which has made the construction of devices Volvo one of the strongest devices building 's 's world for decades.
