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 [...]

Hydrogen as fuel in automobiles

Hydrogen as fuel in automobiles

Hydrogen is a colourless, odourless and inflammable gas that produces a large amount of energy, while undergoing combustion. It is the lightest gas on Earth. The calorific value of hydrogen is 141,790 kJ/kg. It is the highest for any fuel. Hydrogen is the most abundant element in the universe. About 75% of all known matter [...]

Fuel Supply System in Diesel Engine

Fuel Supply System in Diesel Engine

Fuel supply system is a seperate system used to deliver diesel at correct time in correct quantity, to a diesel engine (or C.I engine), for smooth and efficient operation. The operation of a diesel engine is different from that of a petrol engine. In a petrol engine, air-fuel mixture is supplied by a carburetor to [...]

Turbocharger - Introduction, Diagram and Working

Turbocharger – Introduction, Diagram and Working

In an automobile engine, output power varies with change in ambient conditions such as altitude and location. In order to compensate this variation, superchargers are used. Superchargers are devices that raise the pressure of air or air-fuel mixture that is to be supplied to the engine, above atmospheric pressure. By doing so, they compensate the [...]
