Automobile Engineering Questions
Automotive body construction — in a unit type (frameless) body design for passenger vehicles, sheet-metal pressings are welded together to form the load-carrying structure, to which the outer skin or panels are attached. Is this statement accurate?
Wheel alignment terminology — the tilting of the front wheels away from the vertical, as seen from the front of the vehicle (positive angle), is referred to as:
Automotive brakes — the service operation that removes trapped air from hydraulic brake lines and cylinders in order to restore a firm pedal and proper braking response is called:
Steering geometry — an incorrect steering axis inclination (SAI or KPI) most commonly leads to which observable vehicle behaviour on a level road, assuming other settings are nominal?
Engine materials — aluminium alloys are widely used for cylinder blocks primarily because:
Engine design — why is the compression ratio of a spark-ignition (petrol) engine generally kept lower than that of a compression-ignition (Diesel) engine?
Vehicle dynamics — a traction control system (TCS) primarily regulates which quantity to prevent wheel spin during acceleration and thereby maintain tractive capability?
In automotive engine lubrication systems, the engine's oil pump is typically driven by which rotating member so that oil pressure is available immediately and proportionally with engine speed?
In automotive braking systems, what internal construction feature of a ventilated disc brake rotor provides the most effective cooling during vehicle motion?
In automotive specifications and regulatory terminology, the abbreviation G.V.W. stands for which quantity related to a vehicle's allowable operating mass?
In internal combustion engine classification, petrol (gasoline) engines are commonly referred to by which ignition type based on the method of initiating combustion?
Power transmission belts: If belt tension is set excessively high during installation or service, what consequence(s) can follow in typical engine or accessory drive systems?
In spark-ignition (petrol) engines, what is the term for the abnormal condition where the air–fuel mixture ignites before the spark plug fires, due to hot spots or residual heat?
Spark plug operation: When the central electrode reaches a sufficiently high temperature, adhered carbon deposits are burnt off. The temperature at which this self-cleaning begins is termed the spark plug's self-cleaning temperature. Is this statement accurate?
Brake fluid specifications: What is the principal difference between DOT 3 and DOT 4 glycol-based brake fluids as defined by performance standards?
In manual clutch design for passenger vehicles, what is the typical approximate coefficient of friction used for organic clutch facings operating under normal conditions?
In a rack-and-pinion steering system, which component transmits motion from the steering rack ends to the steering knuckles (stub axles), enabling wheel articulation?
Automotive brakes and vapour lock — identify the operating condition that most commonly causes vapour locking in a hydraulic brake system, leading to a soft or fading pedal after repeated use.
Brake disc runout diagnostics — which symptom is most directly associated with lateral runout of a brake disc (rotor) during normal service braking?
Wheel alignment fundamentals — evaluate the statement: “Positive camber is used to compensate for wheels tilting inward due to the weight of the vehicle.” Indicate whether this statement is correct in the traditional alignment context.
