Inspection for Diesel-driven Vehicles

Stage 1

Above Carriage Check: An inspector carries out visual checks on

- Vehicle identity (number plate, engine and chassis numbers)
- Lighting equipment (headlamps, stop lamps, front and rear lamps, direction indicators, etc)
- Bodywork
- Vehicle modification/accessories
- Road wheel and tyres
- General items (seat belts, horn, windscreen, safety devices,speed limiter, etc)

Chassis Dynamometer Smoke Test: Checks Exhaust Emission Level (Applicable for Diesel-driven Vehicles only)

- The chassis dynamometer simulates the load and inertia of the vehicle when driven on the road
- Vehicle wheel power is measured
- Smoke sample is collected from the exhaust pipe

 

Stage 2

Alignment Test: Checks front wheel alignment.
The lateral movement of the front wheels is measured as the vehicle is driven over the side-slip tester.

Brake Test: Determines efficiency of brakes.
The brake tester is used to measure brake performance, efficiency and drag force.

Test results are automatically registered. Test instructions and results are displayed on the overhead indicator board.

Stage 3

Headlight Test: Determines proper alignment and focus of headlamps.
The headlight aimer is used to measure the luminous intensity and the horizontal and vertical aim of each headlamp at high beam.

Sound Level Test The engine is revved and noise emission is measured to determine noise level.

Test results are automatically registered. Test instructions and results are displayed on the overhead indicator board.

Stage 4

Under Carriage Check: Checks the condition of car parts and components.
Vehicle is driven over an inspection pit for visual checks on:

- Chassis
- Exhaust system
- Suspension system
- Steering system
- Brake system
- Leakage

Test instructions and results are displayed on the overhead indicator board.
