BTEB Automotive Mechanics study guide
BTEB Automotive Mechanics · Work through your exam, one topic at a time.
The BTEB Automotive Mechanics credential is a Bangladeshi technical trade qualification awarded through the Bangladesh Technical Education Board system. It signals that a candidate can work safely in a motor workshop and handle the core service and repair tasks of the trade: engine work, driveline components, electrical systems, brakes, steering and suspension, fuel and cooling systems, plus routine maintenance and fault diagnosis. The BTEB Automotive Mechanics study guide has 9 sections and about 2,775 words.
01Workshop Safety
Safety questions reward precise knowledge of causes, controls and emergency actions. Learn the hierarchy of control: eliminate the hazard, substitute a safer method, apply engineering controls (guards, fume extraction, interlocks), then administrative controls (permits, training, signage), and finally personal protective equipment as the last line of defence.
312 words, about 2 min02Tools and Measuring Instruments
Questions test whether you select the right tool and read it correctly. Spanners: open-ended for accessibility, ring for high torque and reduced slip, combination for general work, socket and torque wrench for controlled tightening.
293 words, about 1 min03Automotive Engine Systems and Overhauling
Understand the four-stroke cycle: intake, compression, power, exhaust. Know bore, stroke, swept volume, clearance volume, compression ratio and engine capacity.
256 words, about 1 min04Transmission: Clutch, Gearbox, Differential and Drive Line
A single-plate dry clutch transmits torque through friction between flywheel, friction disc and pressure plate. The release bearing disengages it via the release fork.
239 words, about 1 min05Automotive Electrical and Electronic Systems
Ohm's law (V = IR) and power (P = VI) underpin all circuit questions. Series circuits share voltage and have one current path; parallel circuits share voltage and divide current.
255 words, about 1 min06Braking, Steering and Suspension Systems
Hydraulic braking relies on Pascal's principle: pressure is transmitted equally, so force = pressure x piston area. A larger master cylinder piston increases fluid volume but reduces pressure for a given pedal force; larger wheel cylinders increase braking force.
251 words, about 1 min07Fuel, Lubrication and Cooling Systems
Petrol engines mix fuel and air at a stoichiometric ratio of about 14.7:1 by mass; diesel engines run lean and control power by injected quantity. Carburettors use venturi depression and jets; fuel injection uses sensors and an ECU for precise delivery.
261 words, about 1 min08Vehicle Maintenance, Servicing and Troubleshooting
Servicing follows manufacturer intervals and includes oil and filter changes, fluid checks, brake inspection, tyre rotation, belt replacement and battery checks. Scheduled maintenance prevents failures; condition-based maintenance uses measurement and inspection.
231 words, about 1 min09Trade-related Mathematics, Science and Drawing
Know unit conversions (1 inch = 25.4 mm, 1 litre = 1000 cm3, 1 kW = 1.36 hp), percentages, ratios, averages and simple geometry. Circle area = pi r2; circumference = pi d; cylinder volume = pi r2 h.
