Study Notes
City & Guilds Level 2 Technical Certificate in Land-based Engineering (0171-28)
- This is a sample external test
- The test duration is 2 hours
- The contents include a sample L2 MCQ test (pages 3-17) and answer keys (pages 19-20)
Sample External Test Questions (Page 3-9)
- Question 1: asks about a transmission system in an image. Possible answers include two-wheel drive, tracked, four-wheel drive or hydrostatic
- Question 2: concerns the type of transmission on a combine harvester. Possible answers include semi-powershift, full powershift, mechanical or hydrostatic.
- Question 3: describes a function of a differential in a mechanical power transmission system. Possible answers relate to allowing one wheel to travel faster than the other, transmitting drive, engaging/disengaging drive to wheels or enabling the power take off to operate independently.
- Question 4: asks about a symbol's meaning, referring to factors like transmission oil temperature or level, or engine oil level/pressure.
- Question 5: concerns the purpose of an epicyclic reduction unit in a tractor's final drive system, dealing with increase/decrease in speed and torque.
- Question 6: relates to the benefits of a multi-plate clutch compared to a single clutch, possibly involving things like reduced weight/wear, reduced costs/maintenance or size/surface area
- Question 7: highlights the purpose of a safe isolation procedure before maintenance, focusing on avoiding machine damage or harming personnel.
- Question 8: deals with the sequence of the four-stroke cycle in an internal combustion engine, listing stages of exhaust, induction, compression and power.
- Question 9: identifies the engine configuration in an image, possibly including rotary, horizontal opposed, vee or inline configurations.
- Question 10: describes the firing order of a four-stroke engine's cylinders. The answers are potentially presented in a list format.
- Question 11: inquires about the lubrication system in an image. Potential answers include splash feed, force feed, two-stroke or mist feed.
- Question 12: designates the type of a component in an image, likely a fuel injector, including pintaux, two stage, mechanical, or electronic.
- Question 13: explains how a Selective Catalytic Reduction (SCR) system reduces Nitrogen Oxide emissions, related to chemical reactions with exhaust emissions, removal mechanisms or recirculation.
- Question 14: covers the functions of lubricating oil in an engine, with answers possibly related to sealing, transferring heat, filtering contaminants, reducing friction or preventing moisture ingress.
- Question 15: outlines the correct sequence of the inlet stroke in a two-stroke cycle, covering stages like pressure drops, air/fuel mixture drawing into the crankcase, piston movement etc
- Question 16-20: address component identification (diodes, switches, resistors, fuses) in electrical diagrams.
- Question 21: specifies the unit of measurement for electrical resistance (Ohms).
- Question 22: determines the type of circuit (charging, starting, lighting, fuel gauge).
- Question 23-25: involve calculating current (in amps) and voltage values (in volts).
- Question 26-29: cover component identification (flow control valve, pressure regulating valve, control valve, pressure relief valve, hydraulic motors, hydraulic pumps).
- Question 30 - 33: concern the hydraulic circuit, hydraulic oil reservoir functions (dissipation of heat, storing hydraulic oil, preventing aeration/surging. preventing moisture ingress), and suitable personal protective equipment (PPE) during high-pressure hydraulic system work (safety boots, overall, hard hat and gloves).
- Question 34-37: ask for identification of lights related to anti-lock brakes, trailer brake pressure, differential lock, transmission brakes or 4-wheel drive.
- **Question 38-40:**identify agricultural machines (seed drills, crop sprayers, and soil inverters).
- Question 41-46: relate to tractor starting procedures, safe operation, and attaching PTO-driven implements.
