Isuzu Trooper>> System of decrease in toxicity>> System рециркуляции

4.4. System рециркуляции

System рециркуляции on engines 4ZE1

1 – throttle заслонка
2 – the valve рециркуляции
3 – the thermovacuum valve
4 – from the electronic block of management

The valve рециркуляции 6-cylinder engines

1 – the valve рециркуляции

2 – vacuum hoses

3 – the solenoid

4 – giving of depression from a soaking up collector

Provides temperature decrease in the chamber of combustion for the purpose of decrease in the maintenance of oxides of nitrogen in exhaust gases. Gases go from the exhaust channel of a head of cylinders to soaking up collector through the valve рециркуляции (EGR-valve). The valve diaphragm рециркуляции is connected to the channel in a carburettor flange through the thermovacuum valve. In process of opening throttle заслонки the valve diaphragm opens, providing receipt of exhaust gases in soaking up collector.
