Experiments were conducted to determine exhaust emissions and combustion characteristics of a conventional diesel engine (CE) and high grade low heat rejection diesel engine (LHR) (with air gap insulated piston with superni (an alloy of nickel) crown, air gap insulated liner with superni insert and ceramic coated cylinder head)with different operating conditions [normal temperature and pre-heat...

The emissions control regulations introduced by governments are set to improve engine quality and reduce the impact automobiles have on planet. imposed manufactures proven very difficult meet. To this effect some of leading names in industry were pushed invest significant funding research, development optimisation combustion, powertrain tribology inside ICE. Their goal is reduction fuel consump...

As worldwide automotive ownership is set to exceed 2 billion vehicles by 2030 [1], environmental and economical pressures on the automotive industry mean there is a trend to reduce harmful greenhouse gas emissions whilst simultaneously improving fuel economy. The use of electrical hybrid, start-stop idling and materials light-weighting are some of the technological solutions which can offer eff...

This paper presents the design and simulation of a resonating free liquid-piston compressor (FLPC) equipped with a separated combustion chamber. The FLPC is a proposed device that utilizes combustion of a hydrocarbon fuel to compress air into a high-pressure supply tank, thus potentially serving as a portable power supply candidate for untethered pneumatic systems of human-scale power. The ener...

A special configuration of Stirling liquid piston engine, known as Fluidyne, was invented fifty years ago and many works have been devoted to it since then. variant the Fluidyne is presented, in which two ends U-tube containing are closed by valves, so that system obtained belongs family Ericsson engines rather than engines. This type low-tech considered be suitable for production low-power mec...

An experimental study has been carried out to simultaneously optimize several diesel engine designs and operating parameters for low exhaust emissions using Taguchi method. A single cylinder (DPF make) diesel engine equipped with a high pressure, cam driven mechanical injector has been used in this experiment. The effects of changes in engine design/operating parameters–nozzle spray holes, pist...
