Spur Gear - An Introduction

Spur Gear – An Introduction

In my previous article, I explained worm gears with their advantages, disadvantages and applications. In this article, I will be giving you a brief introduction to spur gear. Introduction: Spur gear is the most common type of gear used. It is used for transmitting power between two parallel shafts. In this type of gear, the [...]

Classification of Unconventional Machining Processes based on Energy Used

Classification of Unconventional Machining Processes based on Energy Used

Based on energy used, unconventional machining processes can be broadly classified into five main types. They are: Mechanical Energy based Unconventional Machining Processes Electrical Energy based Unconventional Machining Processes Electrochemical Energy based Unconventional Machining Processes Chemical Energy based Unconventional Machining Processes Thermo-electrical (or Electro-thermal) Energy based Unconventional Machining Processes 1. Mechanical Energy based Unconventional Machining [...]

Unconventional Machining Processes - Introduction and Classification

Unconventional Machining Processes – Introduction and Classification

An unconventional machining process (or non-traditional machining process) is a special type of machining process in which there is no direct contact between the tool and the workpiece. In unconventional machining, a form of energy is used to remove unwanted material from a given workpiece. Why unconventional machining processes are used? The answer is simple. [...]

How a 3-Way Catalytic Converter Works

How a 3-Way Catalytic Converter Works

A 3-way catalytic converter is a sophisticated device used in the exhaust system of many modern petrol engine vehicles. It converts harmful gases in the engine exhaust to relatively harmless gases. Why should we use 3-way catalytic converters? The exhaust gases from an engine contain harmful substances such as oxides of nitrogen (NOx), carbon monoxide [...]

Internal Combustion Engine - Introduction and Types

Internal Combustion Engine – Introduction and Types

An Internal Combustion Engine (IC Engine) is a type of combustion engine that converts chemical energy into thermal energy, to produce useful mechanical work. In an IC engine, combustion chamber is an integral part of the working fluid circuit. Principle of operation: Air-fuel mixture in the combustion chamber (inside the cylinder) is ignited, either by [...]

Combustion Engine - Definition and Types

Combustion Engine – Definition and Types

A combustion engine is a device that converts chemical energy (in the form of fuel) to useful mechanical energy. Combustion engines can be broadly classified into two types. They are: External Combustion Engine (EC Engine) Internal Combustion Engine (IC Engine) External Combustion Engine (EC Engine): In an external combustion engine, fuel is burnt externally (in [...]
