THE VOLUMETRIC EFFICIENCY OF FOUR-STROKE ENGINES

SAE Technical Paper Series, 1952
<div class="section abstract"><div class="htmlview paragraph">PARAMOUNT among the problems relating to the efficiency of the internal-combustion engine is that of breathing capacity, or air consumption. Considering volumetric efficiency to be the most valuable parameter in an analytical or experimental approach to this problem, the authors ...

Release Process in a Four‐Stroke Engine

Aircraft Engineering and Aerospace Technology, 1947
THE problem of silencing the exhaust of a piston engine requires that attention be given to the two main sources of gas noise; firstly, relatively low frequency vibrations in the exhaust column itself, excited by a pressure pulse produced by the rapid rush of gas from the cylinder into the exhaust pipe, and, secondly, high frequency vibrations ...

Electronic Ignition of four stroke single cylinder engine

SAE Technical Paper Series, 2009
<div class="htmlview paragraph">The demand for the economy due to scarcity of fuel and increased engine performance with less emission will lead to the high level complexity in engine control system. The important factors which affect fuel economy and engine performance are ignition timing and fuel induction.

Four Stroke Engine Geometry for Stratified Charge Combustion

ASME 2005 Internal Combustion Engine Division Fall Technical Conference (ICEF2005), 2005
In 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.

Balancing of High-Speed Four-Stroke Engines

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

Exergy Analysis of a Four Stroke Diesel Engine

2019
Energy 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.
