When testing engines on a bench to determine emissions of harmful substances with exhaust gases and the emission of visible pollutants, the following is carried out:
measurement of emissions of carbon monoxide, hydrocarbons, nitrogen oxide, particulate matter in the ESC cycle
opacity measurement by ELR cycle
measurement of emissions of carbon monoxide, hydrocarbons, nitrogen oxide, particulate matter in the ETC cycle
measurement of visible emissions
When assessing engine power indicators, the laboratory tests automobile engines (gasoline, diesel, gas-diesel, gas) intended for installation on a vehicle on a motor test bench.
The following is determined during the tests:
maximum net power
maximum net torque
fuel consumption
When testing automobile engines intended for installation on vehicles of categories M, N, in a climatic chamber, the following are determined:
reliable engine start temperature
number of attempts for a reliable start
reliable start attempt time
Tests of combustion heaters intended for installation in vehicles with regard to:
emissions of harmful substances with the exhaust gases of the heater
emissions of visible pollutants
functional safety
tightness of the primary circuit of the heat exchanger
temperature, surfaces of combustion heaters and air at the outlet of the heaters
Vehicle testing is carried out on the roads or on a dynamometrical bench.
Determination of the resistance of intake and exhaust systems. The tests determine:
maximum backpressure in the exhaust system at 100% load and rated engine speed
maximum rarefaction in the intake system at 100% load and rated engine speed
Parameters and specification of the on-board diagnostic systems (OBD):
design and visual control (completeness, arrangement of elements, compliance with the standards of diagnostic interfaces, indicators, pointers)
OBD reaction to the simulated malfunction
exhaust of visible pollutants
The following is assessed during the tests:
protection against direct contact with parts under voltage
protection against electric shock due to indirect contact
insulation resistance of high voltage busbars
insulation resistance of the connection system for charging
REESS:
overload protection of REESS
functional safety of electrically driven vehicles
The following is assessed during the tests:
proper and safe operation of special equipment elements
presence of all necessary special equipment elements
location and security of fastening of special equipment elements
tightness of the installed set of gas-cylinder equipment
