Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra rows of radial cy ....etc

research paper on ball piston engine pdf

Abstract:

A patented 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 ( Figures 1 and 2 ) 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 n ....etc

A review of free-piston engine history and applications


Introduction
Extensive use of fossil fuels as an energy source
for both sea and land based transport leads to sig-
nificant amounts of CO2 and other pollutants be-
ing produced. Much research, particularly within
the automotive industry, is being undertaken to de-
velop more environmental friendly fuel chains, and
the fuel cell vehicle stands out as a promising tech-
nology for the future.

abstract
An opposed-piston hydraulic free piston engine operating with homogenous charge compression ignition (HCCI) combustion, has been proposed by State Key Laboratory of Engines as a means of significantly improving the IC engine s cycle thermal efficiency and lowering exhaust emissions. Single and multi-zone Chemkin model with detailed chemical kinetics, and unique piston dynamics extracted from one dimensional gas dynamic model, have been used to analyze the combustion characteristics and engine performance. Intake heating, vari ....etc

Design and analysis of piston 4s S.I engine.

ABSTRACT
The project DESIGN AND ANALYSIS OF 4-STROKE S.I. ENGINE PISTON is about designing the piston according to the forces acting on it from the gases, which are released during the combustion.
The piston head acts as a particular case and hence the piston is analyzed for the stresses developed due to the conditions.
At first, the piston is designed according to the specifications. After the designing, the model is subjected to certain conditions. According to the conditions we have c ....etc
