IVECO Technical Talks: Euro V Standards ISO 17025 Certification

Stabbed Self With Cats Needle
IVECO-FPT collaboration with Industrial-launched a series of talks Techniques, to contact Industrial Fiat specialists with media to disseminate to technical issues that currently prevail. Industrial FPT is the company responsible for Fiat SpA Industrial development, manufacture and sale propulsion systems of commercial vehicles and marine applications and power generation.
Francisco Spasaro, Product Marketing Manager of Iveco Argentina, said on the occasion: "The purpose of this meeting is to share information with the press on certain issues which exist within the industry, update on issues techniques. We want to be the first to bring the media useful information on topics that will be discussed regularly in the coming months. "
In this issue opening, addressed the adaptations to meet the requirements of the Euro V standard, aimed at developing cleaner engines and fully framed in the requirements of the new legislation. Under Argentine law, from 2012 the new approvals must satisfy the Pollutant Standard Euro V, and since 2014 all diesel-powered commercial vehicles sold in the country have to comply with this legislation.
To this end, the resources committed in FPT engines can be divided into
• Motor Configuration
• Post-treatment of gases
engine modifications are intended, in addition to meeting legislative requirements, reduce and optimize the use of fuel. For this purpose, p. eg., nozzles with pressures from 1,600 to 2,200 bar, and turbo VGT (Variable Geometry) and Stage Two (Two Cycles). Simultaneously, the combustion chambers were redesigned.
With these new configurations, optimizing the combustion generating a specific output increased from 15 to 20%. Further processing of gases is the most important in the adaptation of engines to the new requirements. FPT takes two types of technology as a product category: EGR (DPF + DOC) light engine and SCR for medium and heavy duty engines.
• EGR (Exhaust Gas Recirculation)
• DOC (Diesel Oxidation Catalyst)
• DPF (Diesel Particulate Filter)
In the case of lightweight Iveco-Daily-were adopted on EGR, DOC and DPF. The EGR recycles exhaust gases by recirculation at the inlet to decrease the temperature in the combustion chamber, thus reducing the formation of NOx (oxides of nitrogen). The DOC promotes the oxidation of gaseous pollutants, while the DPF absorbing particles, mainly of carbon.
For medium and heavy engines, Iveco chose SCR (Selective Catalytic Reduction) technology, prepared to meet even the Euro VI. Its purpose is to reduce NOx through a reaction solution of urea / water (arNOX 32) of the exhaust gas for nitrogen and water. The adoption of SCR require arNOX supply network 32, which will own warehouse next to the engines.
