Fuel Injection Systems

Continued and Timed Injection Systems

• Continued Injection: Delivers fuel continuously into the intake manifold, regardless of the engine cycle.
• Timed Injection: Synchronizes fuel delivery with the intake stroke of each cylinder for better efficiency and combustion control.

Piston Ring Functions

Primary Roles of Piston Rings

1. Seal the combustion chamber to prevent gas leakage.
2. Control oil consumption by scraping excess oil from the cylinder walls.
3. Transfer heat from the piston to the cylinder wall.

Racing Engine Preference

Petrol engines are favored in racing because they are lighter, provide a higher power-to-weight ratio, and offer faster throttle response, which is ideal for high-speed performance.

The Theory of Change: Planning for Impact

Defining the Theory of Change

The Theory of Change (ToC) is a step-by-step strategic framework that helps you determine how to reach a specific goal.

It serves as both a theory (your best idea of how change will happen) and a road map (showing the path from your current state to your desired future state).

Key Components of the ToC Framework

A robust Theory of Change helps you:

• Clearly define your ultimate goal.
• Identify the necessary steps, actions, or strategies required.
• Understand the expected results (outcomes) from each step.
• Recognize the underlying assumptions and potential real-life challenges.

The Theory of Change is a way to plan how to reach your goal by:

1. Stating what you want (your big goal).
2. Listing

The Optical System in a Mechanical-Optical Comparator

In a mechanical-optical comparator, the optical system is crucial for magnifying small displacements of a plunger or measuring contact. It projects the result onto a screen, allowing for easy and precise reading. The system generally includes several key components:

• A light source
• A mirror or prism
• A pivoted lever system
• A lens system
• A graduated scale or screen

How the Optical Comparator Works

When the plunger makes contact with the workpiece, any small displacement resulting from dimensional variation is transferred through a mechanical linkage (such as a lever). This movement causes a mirror or prism attached to the linkage to tilt. A beam of light is reflected by the mirror through the lens...

The Opioid Crisis: A Case Study in Ethical Failure

An ethical dilemma arises when an individual or organization faces two conflicting moral principles, where neither option leads to a completely ethical outcome. In the context of the opioid crisis, pharmaceutical companies and pharmacies faced a critical choice:

• Maximizing Profits: Aggressively marketing and distributing opioids, despite knowing the devastating effects such as addiction, death, and a widespread social crisis.
• Acting Ethically: Prioritizing public health, transparency, and responsible marketing, even if it meant sacrificing potential revenue and market share.

This dilemma starkly highlights the conflict between economic self-interest and moral responsibility. Instead of choosing... Continue reading "Opioid Crisis: Unraveling Corporate Ethical Failures" »

Operations & Production Management Fundamentals

Transformation Process in Operations

The transformation process refers to the act of converting inputs (materials, labor, capital, information) into outputs (goods and services) through various processes such as manufacturing, service delivery, and assembly.

Model of Operations Management

The basic model involves:

• Inputs (Materials, Labor, Capital, Information) →
• Transformation Process (Manufacturing, Service, Assembly, etc.) →
• Outputs (Products, Services)

Types of Production Systems

Production systems are categorized by volume and variety:

1. Job Shop Production:
   • Low volume, high variety.
   • Example: Custom furniture, tailor-made suits.
2. Batch Production:
   • Production in batches with moderate variety and volume.
