• Four Strokes Of An Engine

Abstract

Just after the piston moves to the bottom of its travel (bottom dead center), the cylinder bore contains the maximum air-fuel mixture possible. The intake valve closes and the piston returns back up the cylinder bore. This is called the compression stroke of the 4-stroke engine process.

Four Strokes Of An Engine

ABSTRACT: Gaseous fuels such as liquefied petroleum gas (LPG) and liquefied natural gas (LNG) have been widely used in commercial vehicles. In this project the main aim is to evaluate the exhaust emission by running the conventional engine on Liquefied Petroleum Gas (LPG) as an alternative fuel for four-stroke spark ignition engine. The primary objective of the study is to determine the performance and the exhaust emissions of the engine using LPG as a fuel. The engine used in the study is originally a single cylinder; four-stroke spark ignition engine with certain modifications is to make to permit the experiments to run on LPG fuel. During the running, the engine was coupled to a ropeway dynamometer to measure several engine performance parameters and a 5-gas analyzer is to be inserted into the engine exhaust tailpipe for measuring the exhaust emissions. Experimental investigations have been carried out to emissions of single cylinder four-stroke spark ignition engine at full throttling position of engine and different load conditions is used to different fuels (Gasoline and LPG). Exhausts are the five gasses measured by the latest technology exhaust analysers are: HC, CO, CO2, O2 and NOx.
