Automobile engine fault detection and repair

Chapter One: Startup Faults

No Response

Diagnosis: Measure battery voltage (below 10V indicates discharge), check terminal condition, and test starter motor continuity.

Repair: Charge battery / replace battery; clean and tighten terminals; replace starter switch or assembly.

Abnormal Noise but Does Not Start

Diagnosis: Inspect starter motor and flywheel ring gear wear, check timing belt/chains for breaks.

Repair: Replace worn parts; replace timing belt/chain and align.

Dies After Starting

Diagnosis: Measure fuel pressure (no pressure indicates pump failure), check fuel filter status, spark plugs/ignition coils.

Repair: Replace fuel pump/filter; replace spark plugs or ignition coils.

Chapter Two: Running Faults

Unstable Idle

Diagnosis: Check for air intake leaks, throttle body carbon buildup, and injector spray volume differences.

Repair: Seal leak areas; clean throttle body; clean/replace injectors.

Insufficient Power

Diagnosis: Inspect air filter, turbocharger pressure, cylinder compression pressure.

Repair: Replace air filter; repair/replace turbocharger; replace piston rings or grind valves.

Overheating

Diagnosis: Check coolant level, water pump operation, radiator blockage, thermostat condition.

Repair: Top off coolant; replace water pump; clean/replace radiator; replace thermostat.

Abnormal Noise

Diagnosis: Listen and locate (knocking check fuel grade/cylinder clearance; valve noise check clearance; bearing noise check bushing).

Repair: Use high-grade fuel / bore cylinder and replace piston; adjust clearance / replace pushrod; replace bearings.

Vibration

Diagnosis: Read misfire data (corresponding cylinder component fault), check engine mount aging.

Repair: Replace misfiring cylinder spark plug/injector; replace engine mounts.

Chapter Three: Fuel and Lubrication System Faults

High Fuel Consumption

Diagnosis: Check injector leakage, fuel pressure, air filter condition.

Repair: Replace injectors; adjust fuel pressure; replace air filter; repair mechanical resistance components.

Abnormal Oil Pressure

Diagnosis: Too low check oil level/oil pump/filter; too high check viscosity/relief valve.

Repair: Add oil / replace pump/filter; replace oil / repair relief valve.

Oil Degradation

Diagnosis: Observe oil condition (black/emulsified/contaminants), measure coolant mix-in.

Repair: Replace oil + filter; replace cylinder gasket and clean oil passages.

Chapter Four: Ignition System Faults

Diagnosis: Use timing light to check ignition timing, measure high-tension wire resistance.

Repair: Adjust timing position; replace aged high-tension wires.

Core Principle: Prioritize simple issues first, inspect easily damaged parts, and have complex faults handled by professionals.
