The internal combustion engines operating in the four-stroke cycle are most widely used on all types vessels with different purpose. Mostly, the vessels use medium and high-speed engines of this type, however, a number of Asian manufacturers produce low-speed four-stroke engines which are capable to operate with direct power transmission to the ...

Emission Control of Four-Stroke Motorcycle Engine
SAE Technical Paper Series, 1995Experimental studies of the intake-generated charge motion (swirl and tumble) and engine combustion were conducted in a 125 cc four-stroke motorcycle engine. In this work, a Variable Inlet Port (VIP) was designed to generate various levels of charge motion in different operation conditions. The static flow test and the engine experiments were performed

Exergy Analysis of a Four Stroke Diesel Engine
2019Energy is the capacity to do work or to cause the changes. It generally consists of two parts, namely, available energy also called as exergy and other is unavailable energy also called as anergy. The available energy is the useful part of the energy from which maximum useful work is obtained.

Balancing of High-Speed Four-Stroke Engines [PDF]
Proceedings of the Institution of Mechanical Engineers: Automobile Division, 1958 The problem of balancing the rotating and reciprocating components of high-speed engines has engaged the attention of engineers for many years with the result that a considerable literature is now available on this subject. Generally, the need to minimize external and internal force and couple unbalance is well recognized, since only in this way is it

Four Stroke Engine Geometry for Stratified Charge Combustion
ASME 2005 Internal Combustion Engine Division Fall Technical Conference (ICEF2005), 2005In four-stroke engines direct injection increases power and fuel economy, which is further improved by charge stratification, due to pumping loss reduction and better combustion efficiency at partial loads. Charge stratification can be obtained by different techniques and injector designs.
