Our approach is to define as accurately as possible, the opportunities of forecasting the environmental and energetically qualities of direct injection Diesel engines for stationary and industrial applications. This research requires the validation of new energy solutions or injection process. Knowing that test bench research of internal combustion engines is a task that requires highly qualified personnel and very expensive equipment for investigate the combustion process, a research program to define the best technical solution involves significant costs. The energetically solution of an internal combustion engine, similar to those examined in this paper, is defined by the following guidelines and parameters: - Control of mixture formation; - Compression ratio; - Average swirl intake number channel; - Geometry of the intake and exhaust cams; - Diagram of distribution; - Drive cam type injection pump; - Geometry of the combustion chamber; - Type and nozzle geometry (sack configuration and l / d ratio ); - Needle stroke; - The diameter and length of the injection pipe; - Amount of injector opening pressure (for hydraulic injectors); - Type of delivery valve; - Time of injection. Based on experience gained during the test at the test bed, we proposed a criterion for assessing qualitative performance of Diesel class discussed above. This criterion refers to environmental and energetically performance, as a prediction of performance at nominal regime, after shorten tests with cold engine.

Starting Conditions

Advance high speed direct injection diesel engines apply high injection pressures, exhaust gas recirculation (EGR), injection timing and swirl ratios to control the combustion process in order to meet the strict emission standards. All these parameters affect, in different ways, the ignition delay (ID) which has an impact on premixed, mixing controlled and diffusion controlled combustion fractions and the resulting engine-out emissions. In this study, the authors derive a new correlation to predict the ID under the different operating conditions in advanced diesel engines. The model results are validated by experimental data in a single-cylinder, direct injection diesel engine equipped with a common rail injection system at different speeds, loads, EGR ratios and swirl ratios. Also, the model is used to predict the performance of two other diesel engines under cold starting conditions.

Although there is one successful high–speed heavy-oil engine employing aif injection, it will not be disputed that the present rapid development of this type of internal combustion engine would not have taken place if a high-pressure air-compressor were an essential accessory. It is perhaps well to emphasise that from the beginning designers of engines of the pure “compression-ignition” type have striven after airless injection of the fuel, the first successful application in this connection being that of Sir James McKechnie, of Vickers, Ltd., in 1910. Subsequent development work by Professor Hawkes and others under the Admiralty brought this method to practical success on submarine engines, and it is interesting to note that as late as 1920 almost all experience with airless injection had been gained in this country.Engines which are the lineal descendants of these early engines, namely, those in which the fuel is injected directly into a combustion chamber of simple form, and known conveniently as the “direct–injection” type, constitute an important section of those engines working successfully at high speeds.
