The Answer for Requirement Number 2
Power generation and transfer is a crucial aspect of farm mechanics, especially in the operation of different types of equipment and systems. Here’s a simple breakdown of how power is produced or transferred in a diesel engine, hydraulic system, and transmission:
(a) Diesel Engine
A diesel engine is a type of internal combustion engine that operates using the diesel cycle. In essence, the air is drawn into the engine’s cylinder, compressed by a piston, and then fuel (diesel) is injected into the hot, compressed air. The heat of the air ignites the fuel, and the explosion pushes the piston down, which turns the crankshaft and generates power.
|1. Intake Stroke||Air is drawn into the cylinder.|
|2. Compression Stroke||The piston compresses the air, making it hot.|
|3. Power Stroke||Diesel is injected and ignites, forcing the piston down.|
|4. Exhaust Stroke||The spent gases are expelled from the cylinder.|
(b) Hydraulic System
Hydraulic systems transfer power by using an incompressible fluid (like oil). The system consists of two pistons and a pipe filled with the fluid. When force is applied to the smaller piston, it creates pressure in the fluid. This pressure is then transferred to the larger piston, amplifying the force.
|Piston 1||Force is applied here, creating pressure in the fluid.|
|Pipe||Filled with hydraulic fluid, transmitting the pressure.|
|Piston 2||The pressure from the fluid exerts force on this piston, doing work.|
A transmission system in a vehicle transfers the power generated by the engine to the wheels. In an automatic transmission, this is accomplished using a complex system of gears and a torque converter that adjusts to the engine’s speed and load automatically.
|Engine||Generates the power that is to be transmitted.|
|Torque Converter||Uses hydraulic fluid to transfer the engine’s torque to the transmission.|
|Gears||Change as needed to optimize power transfer and efficiency based on speed.|
|Output||Transfers the power to the driveshaft and eventually to the wheels.|
These are very simplified descriptions. Each of these systems can get very complex and have many more components involved in their operation. It’s important to learn and understand the details from a reliable source or instructor.
