Injection Pump Function, Types, and Operation
Injection Pump Function
What is the function of an injection pump?
Its function is to send oil to the injectors at the right time, at the correct pressure, and perfectly dosed for each engine’s working condition. Regarding types of mechanical pumps, they can be linear or rotary. Many brands exist, but Bosch and Lucas are among the most representative.
Different Types of Injection Pumps
Linear pumps and rotary pumps.

Thermal Machines
A thermal machine is a device or system that exchanges heat and work with its environment, transforming a substance through a cyclic process. After each cycle, the substance returns to its original state and begins a new cycle. These machines can function as:
- Engines: Convert heat into work.
- Refrigerators or Heat Pumps: Convert work into heat.
Thermal machines convert mechanical energy into heat, and vice versa. Engines convert heat into work, while heat pumps use work to transfer

Hard Disk Controller
An electronic structure that controls mechanical devices.
Physical Structure of the Hard Drive
It is composed of disks or magnetic surface plates.
Partitions
Concept and Reasons for Multiple Partitions
Operating systems work with logical drives, not physical units. Each hard disk can have multiple logical drives, called partitions.
- Organizational Reasons: Allows for better file organization.
- Multiple Operating Systems: Enables installation of multiple OS on a single drive.
- Efficiency
Introduction to Mechanical Systems and Machine Elements
Mechanical Systems (Static Machines)
Concept 1: Machine
A machine is a device that performs work and is devoted to the transformation of energy.
Concept 2: Mechanism
A mechanism is a set of components that serve to guide, transmit, and modify movement.
Concept 3: Design
Design is both functional and aesthetic and is subject to three forces: static, kinematic, and dynamic. It determines if a machine can carry out its intended function.

Conformation by Merger
Types of Conformation by Merger
Conformation by merger involves heating a material to its melting point, transforming it into a liquid, and then pouring it into a mold. After cooling and solidifying, the material is extracted from the mold. The following factors are considered during the emptying process:
- The mold must withstand high temperatures without deforming.
- The mold should allow for homogenous solidification to prevent deformation of the final product.
- Molds must have openings
Introduction to Simple and Complex Machines
Machines
Definition
A machine is a set of parts or organs coupled together, allowing direct or regulated action of a force with the goal of performing a job.
Components
A machine is formed by the structure and mechanisms. The mechanisms are coupled to each piece.
- Structure: The bench, supports, feet, frame, etc.
- Mechanisms: The axles, wheels, guides, pulleys, gears, crank, etc.
Types of Movement
The types of movement that a machine makes are:
- Straight: The move follows a straight-line trajectory, both vertically
