Among the fundamental factors affecting emissions of internal combustion engines is resistance to motion acting on car. This an important factor be taken into account when testing cars in conditions simulated a chassis dynamometer. The dependence driving function vehicle speed determined basis various methods, most frequently used which so-called alternative method specified procedures for type...

Vehicle on road produces large amount of CO, HC and NOx etc. as a exhaust emission. Typically I.C. engine used in automobiles have a problem of pollutant emission, which mainly depends on combustion process occurs in I.C. engines. Incomplete combustion produces large amount of emission gases & gives lower efficiency. To tackle these issues new way of fuel conditioner are developed called as Mag...

The operation of the internal combustion engine leads to production exhaust gases harmful natural environment. introduced standards European emission standard aim, among other things, reduce CO2 emissions. Such assumptions are related reduction fuel consumption engines in vehicles. This means need make structural changes produced engines, and thus displacement while maintaining high power torqu...

The use of diesel engines has increased dramatically in recent years, as the number exhaust emissions. These emissions have potential to endanger Mother Nature and living species within it. Governments all over world introduced legislative rules on emission reduction order limit released into environment through global sustainable development technologies. This compelled automobile manufacturer...

Because of the need to safely vent exhaust gases, most engine dynamometer facilities are not well suited to measuring engine exhaust orifice noise. Depending on the location of the dyno facility within the building, the exhaust system may need to be extended in order to properly vent the exhaust fumes. This additional ducting changes the acoustic modes of the exhaust system which will change th...

ABSTRACT Stringent NOx and particulate emission constraints require high levels of exhaust gas recirculation. In this paper we model and analyze a Variable Valve Timing methodology that in steady-state achieves large levels of internal Exhaust Gas Recirculation (iEGR) or residual charge in Compression Ignition Direct Injection (CIDI) engines. Current external Exhaust Gas Recirculation (eEGR) te...

rate. In the USA, the introduction of federal car exhaust emission standards in 1968 did lead to a reduction in deaths from exhaust poisoning (Clarke & Lester, 1987). EC legislation regarding exhaust emissions has now been introduced into the UK, and the use of catalytic converters (which reduce exhaust carbon monoxide content by 80-90%) is becoming more widespread. The case of a failed suicide...

The paper presents an analysis of the gaseous exhaust emissions along with an analysis of the size and mass distribution of particulate matter from a Euro V compliant road tractor. The vehicle was fitted with an engine of the displacement of 15,6 dm, maximum power output 412 kW generating a maximum torque of 2700 Nm (1991 lb/ft). For the tests the authors used portable exhaust emission analyzer...
