Engine - mechanical part of the 85

Engine - mechanical part of the 85 "failures" of the engine / sluggish acceleration (continued)
Possible causes of fault
"Dips" in the engine-Chairman, sluggish acceleration 5. (Fuel Injection System (Engine 4A-FE, 4A-OE, 5A-FE and 7A-FE)) Defective fuel injection system (see corresponding chapter).
6. Malfunctions in the control system to reduce emissions: • Always enabled (on a hot engine) heating system air inlet air path,
• Always turned on (the engine is cold), exhaust gas recirculation,• Faulty additional accelerator pump (cold engine).
7. The engine gets very hot.
8. Low "compression."
9. Improper clearance in the valves.
Heat ignition engine
Possible causes of fault
Heat
ignition
(Engine

Off
Gahnia ignition) 1. (Carburetor system power supply (motor 4A-F, 5A-P))
Carburetor malfunction: • Sticking to the throttle actuator, • Not regulated by a system subject ¬ normal idle speed control or high-speed idle (when the engine warms up), • Faulty solenoid valve off the fuel supply.
2. (Fuel Injection System (4A-FE engines, 4A-OE, 5A-FE and 7A-FE)) Defective fuel injection system (see corresponding chapter).
3. Incorrect ignition timing.
4. Defective exhaust gas recirculation.
Burning of a silencer, flash in the carburetor
Possible causes of fault
Clapping in the wilderness, the body (only during slowing down, niyadvigatelya) Constant popping deep in shitele system malfunction: • Permanently disabled system fuel cutoff mode to forced labor ¬ convincingly idling, • Permanently disabled damper throttle, • Malfunction (permanent OFF state), the manipulator ("positioner") throttle, • Faults in the air suction in the exhaust manifold.
1. Clogged air filter.
2. Incorrect ignition timing.
3. (Carburetor system power supply (motor 4A-F, 5A-P)) is not working properly control the air valve.
4. (Fuel Injection System (4A-FE engines, 4A-OE, 5A-FE and 7A-FE)) Defective fuel injection system (see corresponding chapter).
5. Improper clearance in the valves.
Flash bangs or a car, or byuratore of inlet 1. Poor the mixture (insufficient fuel).
2. (Carburetor system power supply (motor 4A-F, 5A-P))
Constantly open choke on a cold engine.
3. (Fuel Injection System (4A-FE engines, 4A-OE, 5A-FE and 7A-FE))
Failure in the electronic fuel injection (see corresponding section).
4. Air leak in the pneumatic lines: • Hose forced crankcase ventilation, • valve EGR, • Highway corrector of the mixture warmed motion gatelya ¬, • Intake manifold, • the air intake chamber (cavity) (for engines with fuel injection system), • Housing carb, • Throttle Body (for engines with the system ¬ my fuel injection), • The line of vacuum brake booster, • the boundary between the flow meter temperature and ha ¬ throttle body (for engines with fuel injection system).
5. Incorrect ignition timing.
6. Improper clearance in the valves.
7. The deposits of soot on the walls of the combustion chamber.

Increased oil consumption
Possible causes of fault
Increased
oil consumption 1. Oil leakage.
2. Clogged line of mechanical ventilation crankcase.
3. Worn or damaged piston rings.
4. Wear rods and / or valve guides.
5. Depreciation valve stem seals.

Increased fuel consumption
Possible causes of fault
Increased
fuel 1. Fuel leakage.
2. Clogged air filter.
3. Incorrect ignition timing.
4. (Carburetor system power supply (motor 4A-F, 5A-P))
Carburetor malfunction: • Faulty control system air damper (damper is open to the engine is cold or covered in hot engine), • High frequency of rotation of the normal mode on idle, • Always open the valve Efficiencies.
5. (Fuel Injection System (4A-FE engines, 4A-OE, 5A-FE and 7A-FE)
Malfunction in the fuel injection system (see corresponding chapter): • Faulty fuel injectors, • Faulty valve fuel cutoff on modes of forced idling, • High speed mode to a normal idle speed.
6. Faulty spark plugs.
7. Malfunction of the EGR (the system is always included).
8. Low "compression."
9. The pressure in the tire does not meet the standard (specification).
10. Slipping clutch.
1 1. Poor oastormazhivanie car.
