Emission Labs :
This lab which measures exhaust pipe emissions can conduct pollution
tests on passenger vehicles and light vans on the chassis
Dynamometer in accordance with European , American and Japanese
standards.
The lab has a number of analyzers to measure air pollutants and take
C.V.S. sampling . It can determine the amount of carbon monoxide,
carbon dioxide, nitrogen oxide and unburned hydrocarbons . (Up to
Euro IV Standard)
Different methods are employed for different pollutants:
-Unburned hydrocarbons are measured through Flame Ionization
Detector (FID)
-Nitrogen oxides are measured by way of Chemiluminescences
Detection (CLD)
-Carbon monoxide and dioxide are measured through Non-Dispersive
Infrared Detection (NDIR)
-CVS sampling which matches up to pollutant gas measurement
standards is used to dilute with fresh air the gases that are
emitted and then take samples from the mixture to carry out tests.
The labs apply Critical Flow Venturi (CFV) sampling.
In order to simulate the movement of vehicles on the standard
cycles, chassis dynamometer is used. This chassis dynamometer
simulates the resistance of the vehicle as it is on the road. The
chassis dynamometer used in the lab has a single axis and 2 rollers.
It can simulate the weight of the vehicle through mechanical means.
DC motor is used in the chassis dynamometer. Besides it can be used
to measure the power on the wheels and maximum speed of the vehicle.
The lab equipped with advanced fuel gauging equipment which draw on
the Coriolis method and a device to regulate fuel temperatures, can
accurately measure the amount of fuel consumed by gas-powered
passenger vehicles on the dynamometer chassis.

Emission Lab. According to Euro 4 Standard :
Euro 4 Emission lab has state-of-the-art equipments for measuring exhaust emissions together with a chassis dynamometer for simulating driving cycle of emission standards of passanger cars and light duty trucks (gasoline & fuel gases) according to Euro 4 and motorcycles according to ECE R40.
The equipments of this lab are: modern analyzers and multi ventury CVS sampling system with capability of producing 1-15 m3/min flow rate and tempreture control bags cabinet (12 bags) based on Euro 4 requirements.
The following exhaust emission concentrations can be analysed with the analyzer system:
1- THC 2- CH4 3- CO 4- NOx 5- CO2
Also the chassis dynamometer can change the inertia between 150-3200 kg for simulating driving cycle of emission standards for motorcycles, passenger cars and light duty trucks. This system incorporates an AC motor/generator system with aditional capability for measuring wheel power, acceleration and maximum speed.
Following standards can be performed in this lab:
1- Vehicle Exhaust Emissions 70/220/EEC as last amendment (type I,II,III) for gasoline and fuel gases
2- Vehicle Exhaust Emissions ECE R83-05 (Type I,II,III) for gasoline and fuel gases
3- Vehicle Fuel consumptions 80/1268/EEC as last amendment for gasoline and fuel gases
4- Motorcycle Exhaust Emissions ECE R40 as last amendment
5- Wheel power, acceleration and maximum speed of passenger cars and motorcycles
