Abstract

A rotary engine is one of the ancient internal-combustion engines ever used. These type of engines were designed with an odd number of cylinder per row in a radial configuration. The crack shaft remained stationary throughout the operation. One advantage of this kind of engine is that it is a simple engine that utilizes less moving components. On the other hand, a piston engine or a reciprocating engine is a heat engine that uses one or several reciprocating pistons. The piston engine converts pressure into a rotating motion. A piston engine has the capability to seal the gap in ...

INTERNAL COMBUSTION ENGINE

Introduction The invention and eventual development of internal combustion engines marked a significant stage in the evolution of engines since it provided a way for industrialists and engineers to build an engine that would suit various applications. Unlike the bulky and messy steam engines, internal combustion engines opened the possibilities of creating smaller, but more efficient engines that can be mounted on different types of machineries. The most common applications of which are in transport vehicles such as the engines used in automobiles, trucks, vessels and planes. Moreover, internal combustion engines are also used in non-mobile applications such as ...

Abstract

This article is about two types of engines; the rotary engine and the piston engine. It examines the differences between the two types of engines and their different areas of application. This refers to the specific cars where the two types are used, as well as the market response with reference to the cars in question. Furthermore, the disadvantages and advantages of the two are closely looked into, where it is determined why the piston engine is most preferred by the auto manufacturers and car enthusiasts. Besides, the article concludes with which engine type is suitable depending on the ...

Introduction

An engine is a machine designed to transform energy into convenient mechanical motion. Heat engines, including external combustion engines and internal combustion engines, burns fuel to produce heat that then creates motion. This paper discusses petrol and diesel engines and compares the efficiency of the two engines.

Diesel Combustion Engine

A diesel engine, also referred to as compression ignition engine is an engine with internal combustion. It makes use of the heated compression to initiate ignition. Further, it burns fuel that has been injected in the combustion chamber. Diesel engines have the highest thermal efficiency at any standards, external and internal combustion engines ...

Abstract

Cars have always played an important role in the course of human development. In the past, man had a vision to introduce an invention to transport people along long distances. To turn the vision of a self-propelling automobile into reality, it took the development of a reliable combustion engine that operated on liquid fuel. In 1672, the first steam-powered vehicle as a toy for the Chinese emperor was built by Ferdinand Verbiest, a member of a Jesuit mission in China. As the automobile industry grew, so did the rate of environmental pollution. Car engines are considered to be the prime source of air pollution. The ...

Introduction.

A combustion engine can be defined as any engine that operates through fuel burning. The difference between a combustion engine and steam engine is that the latter uses steam for operation while the former uses gasoline. Combustion engines also use fueled gases such as hydrogen, propane, methane etc which are components of diesel. Combustion engines run on one type of fuel, and may require a series of adaptation to adjust to fuel/air ratio to use other forms of energy (Agrawal, 2006). The combustion process starts in the gasoline cylinder where a mixture of air and gasoline is sprayed. The mixture is ...
