The Potential of Dme-diesel Blends as an Alternative Fuel for Ci Engines
This paper provides a comprehensive review of the technical feasibility of DME-Diesel blend as an alternative fuel for compression-ignition engines for automotive applications. DME is a synthetic fuel produced by the conversion of various feedstocks such as natural gas, coal, oil residues and bio-mass. The compatible properties such as high cetane number and low auto-ignition temperature with s...
متن کاملObserver Based Feedforward Air-fuel Control of Turbocharged Si-engines
Air-fuel control on turbocharged (TC) SI-engines require precise prediction of the cylinder air-charge (CAC). Using an observer it is possible to both estimate the necessary system states and to provide a framework to design the necessary CAC feedforward controller. Here a mean value engine model of a TC SI-engine is used to develop an observer. The output of the observer is fed as an initial c...
متن کاملOptimization-based non-linear Control Law with Increased Robustness for Air Fuel Ratio Control in SI Engines
In spark ignition (SI) engines, the accurate control of air fuel ratio (AFR) in the stoichiometric value is required to reduce emission and fuel consumption. The wide operating range, the inherent nonlinearities and the modeling uncertainties of the engine system are the main difficulties arising in the design of AFR controller. In this paper, an optimization-based nonlinear control law is a...
متن کاملHybrid cars now, fuel cell cars later.
We compare the energy efficiency of hybrid and fuel cell vehicles as well as conventional internal combustion engines. Our analysis indicates that fuel cell vehicles using hydrogen from fossil fuels offer no significant energy efficiency advantage over hybrid vehicles operating in an urban drive cycle. We conclude that priority should be placed on hybrid vehicles by industry and government.
متن کاملBiodiesel as an Alternative Fuel for Diesel Engines
There is growing interest in biodiesel (fatty acid methyl ester or FAME) because of the similarity in its properties when compared to those of diesel fuels. Diesel engines operated on biodiesel have lower emissions of carbon monoxide, unburned hydrocarbons, particulate matter, and air toxics than when operated on petroleum-based diesel fuel. Production of fatty acid methyl ester (FAME) from rap...
