Performance Analysis of a Producer Gas-fuelled Heavy-duty SI Engine at Full-load Operation

Imaging and Analysis of Auto-Ignition and Heavy Knock in a Full Bore Optical SI Engine

The work involved a fundamental study of auto-ignition under unusually high knock intensities for an optical spark ignition engine. The single-cylinder research engine adopted included full bore overhead optical access capable of withstanding continuous peak in-cylinder pressures of up to 150bar. A heavy knock was deliberately induced under relatively low loads using inlet air heating and a pri...

Toward an Improvement of Natural Gas-diesel Dual Fuel Engine Operation at Part Load Condition by Detail CFD Simulation

Natural gas-diesel dual fuel combustion is a beneficial strategy for achieving high efficient and low emissions operation in compression ignition engines, especially in genset application heavy duty diesel engine at rated power. This study aims to investigate a dual fuel engine performance and emissions using premixed natural gas and early direct injection of diesel fuel. Due to the different r...

Performance analysis of biogas premixed charge diesel dual fuelled engine

This paper presents the technical performance measurements of biogas premixed charge diesel dual fuelled engine. A 4-stroke research diesel engine was used for the performance analysis. The performance parameters like engine brake power, brake specific fuel consumption, volumetric efficiency and brake thermal efficiency were measured and compared with conventional diesel with different proporti...

performance and emission analysis of combustion chamber of a turboprop engine at different operation regimes

performance analysis of jet engines in various environmental conditions is important and is the first step in the design of such engines. in this paper, the performance of a typical turboprop engine was modeled in the commercial software gasturb10 and the obtained results are validated at three flight regimes take off, military and 100% normal using engine test results. performance analysis of ...
