Nissan Micra Engine & Emission Control System Description - EF & EC-2 Diagram

This is page EF & EC-2 of a Nissan factory service manual section titled 'Engine and Emission Control System Description.' The page presents a table listing the vehicle's engine fuel and emission control systems alongside their major components. The engine fuel system comprises the air inlet system (A.T.C. air cleaner, idle compensator, air temperature sensor), automatic choke (P.T.C. heater), and idle speed control system (idle speed control solenoid, lighting switch, rear defogger switch). The crankcase emission control system uses a P.C.V. valve. The exhaust emission control system includes the air injection valve (A.I.V.) system with one air injection valve, one pipe, and an A.B. valve; the E.G.R. control system with an E.G.R. control valve and 2-port bimetal thermal vacuum valve; and the throttle opener control system with a servo diaphragm, solenoid valve, vacuum control valve, speed detecting switch/amplifier (M/T), and inhibitor switch (A/T). The evaporative emission control system uses a carbon canister. Below the table is an exploded line drawing of the carbureted engine showing hose routing and component locations, with callouts for the distributor, fuel pump, T.O.C.S. control valve, fuel feed/return hoses, E.G.R. valve and tube, thermal vacuum valve, A.B. valve, carburetor, blow-by hose, throttle opener, and connections to the air cleaner, intake manifold, and canister.
