Agricultural Technology

This module presents the fundamental principles of the following from both a theoretical classroom based and practical workshop perspective.

• Internal combustion SI and CI Engines and ancillary systems

• Transmission and clutch systems including torque convertors

• Basics of hydraulics and control systems

1. Describe the cycle of operation of an Internal Combustion (IC) engine

2. Dismantle, measure and determine the serviceability and tolerances of the mechanical components and also reassemble Spark Ignition (SI) and Compression ignition (CI) automotive IC engines

3. Describe the basic function and operation of the lubrication and cooling systems of the automotive internal combustion engine and identify main components of these systems.

4. Describe the relationship between overall gear ratio, engine speed/wheel speed and engine torque/wheel torque and Clutch friction systems

5. Dismantle gearbox bench units, identify and examine the components, produce a written report on condition, calculate the gear ratios and reassemble as per manufacturer's specifications

6. Identify and examine an automotive torque convertor and epicyclical gear train transmission and measure oil pressures and hydraulically operated clutch pack friction driven systems.

7. Describe the functions of hydraulic systems and components and test circuits.

8. Interpret and design and calculate hydraulic circuits flow rates and pressures.

9. Identify different oil types, specifications, contamination types and properties of oils used in agricultural applications
