1How many degrees of crankshaft rotation are completed during one full 4-stroke cycle of an internal combustion (IC) engine?
A.720°
B.360°
C.180°
D.540°
Explanation: A 4-stroke internal combustion engine completes one thermodynamic cycle across four piston strokes (intake, compression, power, exhaust), requiring two full revolutions of the crankshaft (2 × 360° = 720°).
2Which component in a diesel engine injects finely atomized fuel into the cylinder at high pressure at the end of the compression stroke?
A.Spark plug
B.Fuel injector
C.Carburetor
D.Governor
Explanation: The fuel injector atomizes diesel fuel under high pressure and sprays it into the highly compressed, hot cylinder air to ignite the air-fuel mixture in a compression-ignition engine.
3What is the typical compression ratio range for commercial tractor diesel (compression-ignition) engines?
A.6:1 to 10:1
B.10:1 to 12:1
C.14:1 to 22:1
D.25:1 to 35:1
Explanation: Tractor diesel engines rely on auto-ignition of fuel through heat generated by high compression, requiring compression ratios typically ranging from 14:1 to 22:1.
4Which device in a tractor allows the engine power to be smoothly engaged or disengaged from the transmission gearbox?
A.Differential
B.Final drive
C.PTO shaft
D.Clutch
Explanation: The clutch connects and disconnects the engine flywheel from the transmission input shaft, enabling smooth gear shifting and stopping without stalling the engine.
5What is the standard rotation speed (in rpm) of a standard Category 1 & 2 tractor Power Take-Off (PTO) shaft at rated engine speed?
A.540 rpm
B.1000 rpm
C.720 rpm
D.1500 rpm
Explanation: The standard PTO speed established for most agricultural tractors and matching rotary implements is 540 ± 10 rpm at rated engine speed.
6Which hydraulic control mode on a tractor automatically maintains a constant draft force (pulling resistance) on a mounted plough in uneven soil?
A.Position control
B.Draft control
C.Flow control
D.Remote valve control
Explanation: Draft control senses soil resistance on the lower links or top link and automatically raises or lowers the implement slightly to maintain uniform draft force and prevent wheel slip.
7Which part of a mouldboard plough receives the soil slice cut by the share, turns it over, and pulverizes it?
A.Landside
B.Coulter
C.Mouldboard
D.Frog
Explanation: The mouldboard is the curved steel plate fitted behind the share that lifts, turns, pulverizes, and flips the furrow slice to bury weeds and crop residue.
8Which part of a mouldboard plough cuts the bottom of the furrow slice horizontally?
A.Shin
B.Landside
C.Gunnel
D.Share
Explanation: The share is the sharp cutting edge located at the bottom front of the plough bottom that makes the horizontal cut underneath the furrow slice.
9Under which soil conditions is a disc plough preferred over a conventional mouldboard plough?
A.Hard, dry, stony, or root-infested soils
B.Wet puddled paddy fields only
C.Sandy loose soils free from stones
D.Soft moist loamy soils
Explanation: Disc ploughs roll over obstacles like rocks and roots without bending, making them ideal for hard, dry, trashy, and stony fields where mouldboard plough shares would break.
10In a tractor-mounted disc plough, what is the typical range of the disc angle (angle of disc plane to direction of motion)?
A.15° to 25°
B.42° to 45°
C.60° to 70°
D.80° to 90°
Explanation: The disc angle (the angle between the plane of the disc edge and the line of motion) is typically set between 42° and 45° to ensure proper penetration and side turning.
