1984 Nissan 300ZX – PDF Engine Fuel & Emission Control System (Section EF & EC)
Get the same level of information about your 1984 Nissan 300ZX vehicle that your official dealer has. Every single element of service, repair and maintenance is included in this fully updated workshop manual. From changing a wiper blade to a full engine rebuild, every procedure is covered with simple step by step illustrated instructions.
Do not remove the fuel temperature sensor, handle air flow meter carefully t o avoid damage, do not clean air flow meter, even a slight leak i n the air intake system can cause serious.
When installing large capacity wireless equipment or vehicle phone, be, sure to obsetve following it, may adversely affect electronic control systems depending its installation location, keep the antenna far possible.
) Also keep antenna feeder line, more than cm (7 9 in) away, adjust the antenna feeder line so, that the standing-wave ratio can be.
Do not operate fuel pump when, there i s no fuel lines, do not use anti-freeze agents i n fuel, do not reuse fuel hose clamps.
Securely connect E C C S harness, a poor connection can cause an extremely high (surge) voltage, develop in coil condenser, thus, resulting in damage t o IC circuit.
Harnesses, t o prevent an E C C S, o f external noise, degraded operation, before removing parts, turn o f f ignition switch then disconnect, e G R control solenoid valve.
The amount of fuel t o be injected determined by, the injection pulse duration as well by pressure, difference between fuel pressure and intake manifold vacuum pressure, controls only the injection pulse duration For.
Reason, the pressure difference between fuel, pressure and intake manifold vacuum pressure, should be maintained a t a constant level Since, intake manifold vacuum pressure varies with engine.
Operating conditions, a pressure regulator IS placed, in the fuel line to regulate fuel pressure, response t o changes in intake manifold vacuum, the turbocharger is installed on the exhaust manifold This system utilizes exhaust gas energy.
Spin the turbine wheel which directly connected, t o the compressor wheel The compressor supplies, pressurized air through throttle chamber into, the intake manifold Thus, the turbocharger increases charging efficiency thereby increases.
To prevent an excessive rise supercharging, pressure, the turbine speed maintained within, safe range by controlling amount exhaust, gas that passes through turbine This system.
Consists of a by-pass valve which allows some, to prevent an abnormal rise supercharging, pressure, and possible engine damage, case, by-pass valve fails t o open properly, an emergency.
Relief valve is provided as a safety device, and power supply, inspection lamps diagnostic, mode selector The control unit controls, amount of fuel that is injected, ignition timing, idle.
Crank angle sensor has rotor plate and wave forming circuit Rotor plate has 360 slits 1″ signal, (engine speed signal) and 6 slits 120″ signal, (crank angle signal) Light Emitting Diodes.
