Stringent requirements of reduced NOx emission limits in the US have presented engineers and technical staff with numerous challenges. Several in-cylinder technical solutions have been developed for diesel engines to meet 2010 emission standards. These technologies have been optimized and have yielded impressive engine-out results in their ability to reduce emissions to extremely low levels. However, current and state-of-the-art in-cylinder solutions have fallen short of achieving the limits imposed on diesel emissions for 2010.

Meeting the requirements of heavy-duty engine emissions regulations is a challenge for all engine manufacturers. Since the introduction of Exhaust Gas Recirculation (EGR) in medium and heavy-duty diesel engines, these systems have become more sophisticated and tightly integrated with emission control systems. This 2-day seminar will explore the advantages and disadvantages of EGR and the most effective implementation of various EGR systems. This seminar will begin by defining EGR and why it is used in diesel engines, along with an explanation of the mechanisms by which EGR is able to reduce NOx.

Stringent emission norms for better quality of environmental air triggers a challenge for OEMs. This is because selection of appropriate technology to meet stringent emission norms has to be ensured with improve fuel efficiency and control cost. This paper highlights an overview of hardware development and calibration strategies carried out for up gradation of 2.2 L common rail direct injection diesel engine, to meet BS V Emissions norms. Existing BS IV compliance engine is selected as a base engine. Target was to minimize possible engine out emission with reduce dependency on after treatment. Major hardware changes in the baseline engine includes reduction in compression ratio, Injectors, EGR cooler optimization, Turbocharger, Diesel oxidation catalyst.

Plant origin vegetable oils are long considered as a potential alternative fuel for diesel engine applications. However, higher viscosity and density compounded with poor cold flow properties of these oils lead to serious operational and durability problems in diesel engines like injector chocking, higher deposit formations, poor combustion characteristics etc. In this context, application of additives in neat vegetable oil to enable them for engine application seem to present a promising alternative for rural stationary diesel engines where the complex transesterification process for biodiesel production from vegetable oils is not feasible. In the present study, Calophyllum vegetable oil was blended with 10%, 20% and 30% by volume of Isopropyl alcohol and named as CI10, CI20 and CI30 respectively. Neat diesel was named as D100.

Diethyl Ether (DEE) is a promising oxygenated renewable bio-base resource fuel for diesel engines owing to its high ignition quality. An experimental investigation has been carried out to evaluate the effect of blends of DEE with diesel as an oxygenate and cetane improver on the combustion, performance and emission characteristics of a direct injection diesel engine. In this study, 2%, 5%, 8%, 10%, 15%, 20% and 25% diethyl ether (by volume) were blended into diesel. The engine tests were carried out for 10%, 25%, 50%, 75% of full load and 100% load. The laboratory fuel tests also carried out to measure the basic properties such as density, kinematic viscosity, calorific value, cetane index, flash point, distillation profile and miscibility. Laboratory fuel tests showed that the DEE can be mixed in any proportion in diesel fuel as it is completely miscible with diesel fuel.

Valve trains are highly burdened powertrain subsystem which has to undergo high fatigue cycles during its service lifespan. Wear enhances valve lash thus depreciating the performance drastically. Analytical advances have helped engineers to predict parameters such as wear, contact stresses, lubrication etc. to uphold the durability of valve train components. Most of the genset and industrial engines running at medium speed use type 5 valve train. In this paper, our study involves about crack induced “wear” due to hertzian stress on rocker toe and the process followed to resolve the problem for a medium speed diesel engine We experienced the problem of rocker toe crack resulting in toe wear in field and on test bed. Our investigations led us to evaluate the life of a rocker toe by specifically developing a test cycle to reproduce the wear due to induced cracks as well as to assess the durability.

The stringent emission norms and increasing demand for engines with higher power density lead to an extensive investigation of parameters affecting combustion performance. Recent emission norms have forced the engine manufacturers to reduce the Particulate matter (PM) emissions along with other emissions substantially. In order to achieve lo PM emissions the lubrication oil consumption need to be controlled by optimizing piston group design with low liner bore distortion. Bore Distortion is the deviation of actual profile from perfect circular profile at any plane perpendicular to axis of cylinder. Liner bore distortion in engines causes number of problems like deterioration of piston ring performance, liner-ring conformability issues, high lubricating oil consumption and emissions.

Title: Novel Conceptual approaches for improvements in Compression ratio for Diesel Engines Author: Mandagaddi Sireesha Affiliated To: Robert Bosch Engineering and Business Solutions Abstract: In diesel systems, compression ratio plays an important role in the combustion process.The volume of air that is sucked into the cylinder and which will be further compressed in compression stroke depends on the swept volume within the cylinder(ie,piston movement from TDC to BDC). In this paper the author gives two proposals: • To achieve greater compression ratio for the existing cylinder size by increasing the swept volume. • To achieve different compression ratio’s for the existing cylinder size by having different swept volumes. First proposal, a greater compression ratio can be achieved for the existing cylinder size by increasing the swept volume during intake stroke(ie, when the piston is travelling towards BDC from TDC ) .

Oil pump is one of the important engine parasitic loads which takes up engine power through crankshaft to deliver oil flow rate according to engine demand to maintain required oil pressure. The proper functioning of oil pump along with optimum design parameters over various operating conditions is considered for required engine oil pressure. Pressure relief passage is also critical from design point of view as it maintains the oil pressure in the engine. Optimal levels of oil pressure and flow are very important for satisfied performance and lubrication of various engine parts. Low oil pressure will lead to seizure of engine and high oil pressure leads to failure of oil filters, gasket sealing, etc. Optimization of pressure relief passage area along with other internal systems will also reduce the power consumed by the pump.

Indian emission norms for stationary Gensets will be upgraded from CPCB I to CPCB II. These new emission norms call for a significant change in emission limits. CPCB II emission norms call for 62% reduction in NOx+HC and 33% reduction in particulates for engines between 75 – 800 kW power range compared to existing CPCB I norms. CPCB II norms are more stringent as compared to EU Stage IIIA and CEV BS III. To meet equivalent emission norms in US and Europe most of the engine manufacturers have used Common Rail Direct Injection (CRDI) or electronic unit injection as the fuel injection technology. This paper describes mechanical fuel injection solution for meeting CPCB II emission norms on engines between 93 kW up to 552 kW with acceptable fuel consumption values. The paper presents simulation and experimentation work carried out to achieve the norms for the said power ratings.

Development trend in diesel engines is to downsize and develop more power from same size of engine. This requires additional air flow and hence increased boost pressure ratio (BPR). With increased brake mean effective pressure (BMEP), the altitude capability of engine reduces. This paper presents a novel approach to estimate the altitude capability of engine and calculate deration factor. As the altitude above sea level increases, ambient pressure decreases, air becomes thinner. For same altitude ambient temperature also varies as per seasonal changes. This results in change (reduction) in ambient air density. This reduction has significant effect on turbocharger (TC), Intercooler and engine performance. Beyond a limiting altitude, engine performance shall be compromised to avoid any damage to engine and its components.
