A linear time invariant (LTI) model of a marine diesel engine is presented. The effect of the discontinuity of the fuel injection into the cylinders and the injection period is considered. The proposed discrete model consists of a sampler and zero-order-hold mechanism, representing the fuel injection process. The design of the discrete controller is based on the pole assignment of the characteristic polynomial of the closed-loop transfer function with the goal of achieving zero steady-state error, and satisfying other design specifications. A numerical example illustrating the characteristic performance of a two stroke marine diesel engine is presented.

The present paper deals with the influence of fuel properties on the spray behaviour. This influence was studiedexperimentally using a common rail injection system from a medium speed diesel engine. The experiments have been performed with diesel fuel (EN-590) and heavy fuel oil (RMG 180) on a constant volume chamber at room temperature. Comparison of the spray characteristics shows that the heavy fuel oil penetrates deeper in the chamber. However, the diesel spray has a bigger cone angle. These results formed the basis for a further development of the 1D-model [1] to predict the spray penetration by considering the fuel properties and temperature.DOI: http://dx.doi.org/10.4995/ILASS2017.2017.4787

Abstract The most potential long-term and renewable substitute of mineral diesel are biofuels. The growth and degradation of energy resources have an enormous influence on the long-term viability of the human community. Alcohols are gaining prominence in the current renewable energy scenario due to their ease of manufacturing and fuel characteristics. In this investigation, hexanol-diesel blend ratios (up to 20% v/v) is taken into account for this investigation in a single cylinder, water cooled, unmodified 4-stroke DI diesel engine. The increase in 1-hexanol volume content correlates to an improvement in combustion thereby promoting brake thermal efficiency. The greater concentration of oxygen in 1-hexanol reduces emission viz. HC and CO and increases value of NOx. Current investigation recommends a feasible option to substitute ULSD for the capabilities of 1-hexanol.
