In 1980 the EPA (Environmental Protection Agency) of America proclaimed that the testing method for exhaust gas regulations would be revised in 1984 for heavy duty engines (HDE) with a gross volumic weight of over 6000 lbs. The concept of this testing has changed conventional 13-mode (steady cycle test) into transient cycle mode. Around that period, automotive manufacturers (in particular makers of trucks) were interested in the transient test system for heavy duty engine test procedures. At that time Meidensha had already developed the HDE exhaust gas test system to meet with the approval of the US, EPA. This test system is presently operating well at a truck manufacturer. The authors describe the HDE Exhaust Gas Test System, mainly in conjunction with operation and control of transient cycles.
