Effect of Direct Injection Diesel Engine Convert to Sequential Injection CNG Engine in Intake Port Gas Flow Pressure Profile
The one dimension computational model of a sequential injection engine, which runs on compressed natural gas (CNG) with spark ignition, is developed for this study, to simulate the performance of gas flow pressure profile, under various speed conditions. The computational model is used to simulate and study of the steady state and transient processes of the intake manifold. The sequential injec...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
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...
متن کاملFlame Front Propagation in an Optical GDI Engine under Stoichiometric and Lean Burn Conditions
Lean fueling of spark ignited (SI) engines is a valid method for increasing efficiency and reducing nitric oxide (NOx) emissions. Gasoline direct injection (GDI) allows better fuel economy with respect to the port-fuel injection configuration, through greater flexibility to load changes, reduced tendency to abnormal combustion, and reduction of pumping and heat losses. During homogenous charge ...
متن کاملConversion of Diesel Engine to Port Injection CNG Engine Using Gaseous Injector Nozzle Multi Holes Geometries Improvement: A Review
This paper is the representation of the computational and experimental methods of a new injector nozzle for a sequential port injection CNG engine. The objective of this study was to review the previous research in the development of gaseous fuel injector for port injection CNG engine converted from diesel engine. Next, a simulation of the fuel flow of the new injector nozzle was made using FLU...
