High Efficiency Miller Cycle Gas Engine
1. INTRODUCTION
The output of gas engines for cogeneration mainly ranges from 100 to 1 000 kW. The present gas engines are broadly classified in two types: lean-burn system (1) and stoichiometric air-fuel ratio combustion system, with the lower output engines using the stoichiometric Air-fuel ratio combustion system while the medium and large size engines adopting the lean-burn system. The lean-burn system generally features in high generating efficiency and low NOx emission in ad ....etc

Abstract:
new power machine concept has been designed and analyzed for production, and proof of principle subscale tests have been performed, with positive results. The machine design concept is applicable as a compressor, pump, motor, or engine. Simplicity of design based on spherical ball pistons enables a low moving part count, high power to weight ratio, elimination of valve train and water cooling systems, and perfect dynamic balance.

The new design concept utilizes novel kinematic design to completely eliminate inertial loads that w ....etc

INTRODUCTION
A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process. Water is a useful and cheap medium for transferring heat to a process. When water is boiled into steam its volume increases about 1,600 times, producing a force that is almost as explosive as gunpowder. This causes the boiler to ....etc

Six-Stroke, High-Efficiency Quasiturbine Concept Engine
With Distinct, Thermally-Insulated
Compression and Expansion Components

George Marchetti and Gilles Saint-Hilaire


Need to increase engine thermal efficiency. This paper presents a Quasiturbine thermal management strategy in the development of high-efficiency engines for the 21st century. In the concept engine, high-octane fuels are preferred because higher engine efficiencies can be attained with these fuels. Higher efficiencies mean less fuel consumption a ....etc
