Overview
自動車排出ガス規制 automobile exhaust gas emissions regulations, the automobile of the internal combustion engine.
* 単体規制 Single Regulation (type regulation) applied to new models by the manufacturer * 車種規制 Vehicle Regulation constant regulation

H
"H" is the 1975 (50年度) emission standards. Also in 1975 in the United States similar regulations came into effect.
* H-B210 meets H-level emission standards * H-B120 from 1975 uses NAPS-A engine A12
EGR
All B211 (from December 1975) and VB210 (from October 1975) used EGR Exhaust Gas Reduction. This included Vans which were not fitted with catalytic converters.
Catalyst
Nissan system's of exhaust gas cleaning by catalyzed oxidation (NAPS) adopted. A 2-way catalytic converter converted carbon monoxide (CO) and unburned hydrocarbons (HC) to produce "harmless" carbon dioxide (CO2) and water (H2O). It was only later than CO2 was acknowledged to be a pollutant itself. NOTE: In 1980 the 3-way converter introduced a 3rd reaction to reduce the third major pollutant NOx.
To enable efficient conversion, extra oxygen is introduced into the exhaust system by use of Nissan A.I.S. (Air Injection System), using a passive air induction (tuned pulse-flow) system. It used a cylinder head with an air passage drilled from front to back.
No feedback was used to control the fuel system. A carefully tuned carburetor was sufficient.
