use of crude filtered vegetable oil as a fuel in Diesel Engines state of the art literature review
Renewable & Sustainable Energy Reviews, 2010Co-Authors: S. S. Sidibé, G. Vaitilingom, Joël Blin, Yao AzoumahAbstract:Many studies have been published on vegetable oil use in Diesel Engines. The different authors unanimously acknowledge the potential and merits of this renewable fuel. Typically, Straight Vegetable Oils (SVOs) produced locally on a small scale, have proven to be easy to produce with very little environmental impact. However, as their physico-chemical characteristics differ from those of Diesel oil, their use in Diesel Engines can lead to a certain number of technical problems over time. In bibliography, there is substantial disagreement between authors regarding the advanced phenomena linked to this problems and the recommended solutions. Some of these publications treat options individually without any real comparison between them. Another observation is that the literature rarely tackles problems linked to vegetable oil quality. This paper sets out to review the state of the art for SVO use as fuel in Diesel Engines, based on a bibliographic study (literature review). The first section of the document examines the influence of the type and quality of vegetable oils for fuel use in Diesel Engines. The second section discusses the advantages and disadvantages of two options recommended for SVO use in Diesel Engines: dual fuelling and blending with Diesel fuel.

Sliding mode control for variable geometry turbocharged Diesel Engines
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000Co-Authors: V.l. Utkin, I. Kolmanovsky, Hao-chi Chang, J.a. CookAbstract:Accurate air-to-fuel ratio and exhaust gas recirculation (EGR) rate control are important for emission reduction in turbocharged Diesel Engines. In the paper, assuming that the Diesel engine is equipped with a variable geometry turbocharger, a sliding mode controller is developed to control the turbine vanes so that, in conjunction with an EGR valve controller, stabilization of the engine variables to the desired equilibrium is achieved.

constructive lyapunov control design for turbocharged Diesel Engines
IEEE Transactions on Control Systems and Technology, 2000Co-Authors: Mrdjan J Jankovic, I. KolmanovskyAbstract:Presents a control design method for Diesel Engines equipped with a variable geometry turbocharger and an exhaust gas recirculation valve. Our control objective is to regulate the air-fuel ratio and the fraction of recirculated exhaust gas to their respective set points that depend on engine operating conditions. Interactions between the two actuators and nonlinear behavior of the system make the problem difficult to handle using classical control design methods. Instead, we employ a control Lyapunov function (CLF) based nonlinear control design method because it possesses a guaranteed robustness property equivalent to gain and phase margins. The CLF is constructed using input-output linearization of a reduced order Diesel engine model. The controller has been tested in simulations on the full order model as well as experimentally in the dynamometer test cell.

Robust nonlinear controller for turbocharged Diesel Engines
Proceedings of the 1998 American Control Conference. ACC (IEEE Cat. No.98CH36207), 1998Co-Authors: M. Jankovic, I. KolmanovskyAbstract:This paper addresses a problem of controlling Diesel Engines equipped with a variable geometry turbocharger and an exhaust gas recirculation valve. The presence of two actuators and nonlinear behavior of the system makes the problem difficult to handle using classical control designs. Instead, we employ a recently developed control Lyapunov function based design method that guarantees a robustness property interpretable as gain and phase margins. The controller has been tested in simulations and experimentally in the dynamometer test cell.

Utilization of waste plastic oil in Diesel Engines: a review
Reviews in Environmental Science and Bio Technology, 2019Co-Authors: D. Damodharan, Melvin Victor Poures, Krishna Gopal, B. Rajesh Kumar, B. SethuramasamyrajaAbstract:Disposal of waste plastic accumulated in landfills is critical from the environmental perspective. The energy embodied in waste plastic could be recovered by catalytic pyrolysis as waste plastic oil (WPO) which could be recycled as a fuel for Diesel Engines. This method presents a sustainable solution for (a) waste plastic management as the gap between global plastic production and waste plastic generation keeps widening, (b) replacing Diesel partially or wholly which is currently extracted from fast depleting fossil crude oil. The present work attempts to bring together all the investigations pertaining to WPO usage either (a) as a neat fuel or (b) as a blend component with Diesel or (c) with an oxygenated additive till date in Diesel Engines and reviews the engine’s performance, emission and combustion characteristics. Majority of the works utilised WPO extracted from mixed waste plastic as a feedstock using a laboratory scale batch reactor via catalytic pyrolysis. Silica, Alumina, ZSM-5 and Kaolin were used as catalysts. This method often yielded up to 80% of liquid WPO. This oil had a slightly lower cetane number than fossil Diesel and hence produced longer ignition delays and higher heat releases during premixed combustion phasing. NO_x emissions were higher with WPO which is addressed by modifying the injection timing or by means of EGR. Contrary to popular belief, smoke emissions are mostly lower with WPO and could be brought down further to Euro levels by the use of oxygenated additives. In summary, WPO was found to run smoothly in Diesel Engines and more work is necessary to study the PM characterisation and long-term durability of the engine when fueled with this oil.
