  • Critical Monitoring of Forklift Emissions and Warehouse Ambient Air Quality - Case Study

    Our team of experts has been hard at work and has just released an industry-leading report detailing Forklift Emissions in Warehouses: The main objectives of this study were to investigate the effects of different engine conditions on exhaust gas emissions and to observe the effect that forklift emissions have on the ambient air quality of the warehouse.             ...

  • Combustion strategies for PFI hydrogen IC engines

    Hydrogen is a very interesting fuel when it comes to load control. The high flame speeds of hydrogen mixtures and its wide flammability limits permit very lean operation. Where possible, Wide Open Throttle (WOT) operation is used, which regulates the load with the mixture richness (qualitative control) instead of using volumetric regulation (quantitative control) and, thus, avoiding pumping ...

  • Pragmatic Efficiency Limits for Internal Combustion Engines

    This article gives an overview of the thermodynamic principles demonstrating that the maximum efficiency theoretically possible with a hydrocarbon fueled internal combustion engine is one hundred percent. From this basis the focus turns to articulating irreversibilities that naturally occur within the processes of converting the chemical energy in the fuel into shaft work. These losses are ...

  • A diesel compound HCCI combustion engine based on injection strategy control

    This paper presents a compound combustion technology of "Premixed Combustion" and "Lean Diffusion Combustion" for the purpose of realising the concept of homogeneous charge compression ignition (HCCI) combustion in a DI diesel engine. The premixed combustion is achieved by the technology of multi-pulse fuel injection. The start of pulse injection, injection-pulse number, injection period of each ...

  • Decomposition method as a new type of second law analysis of the combustion process of internal combustion engines

    The method presented in this paper gives not only the availability loss in each elementary step of the whole process in the engine, but also an insight into how big is the part of burnt fuel available during an elementary piston motion, something which cannot even theoretically be realised as pΔV work. This method is based on decomposition of a complex real process to so–called elementary ...

  • Development of a risk-based Combustion Toxicity Index for engineering materials

    The various types of modern materials widely used in engineering works possess high risk of combustion. During combustion of these materials, toxic gases of varying concentrations are generated. Inhalation of toxic combustion products is the major cause of death during fires. Increased knowledge of the combustion products and their toxicity could decrease the risks. This paper describes the ...

  • Hydrogen-diesel dual fuel combustion in a direct injection diesel engine

    Hydrogen is expected to be one of the most important fuels in the near future to meet the stringent emission norms. Hence in the present study, the combustion of hydrogen-diesel duel fuelled engine was investigated. Hydrogen was injected in the intake port during the suction stroke and diesel was injected inside the combustion chamber near TDC. The start of injection for hydrogen was maintained ...

  • Determination of optimum speed of an internal combustion engine by exergy analysis

    In this study, energy and exergy analysis are applied to the experimental data of an internal combustion engine operating on the conventional Otto cycle. The data are collected using an engine test unit which enables accurate measurements of fuel flow rate, combustion air flow rate, engine load, engine speed and all the relevant temperatures. Energy and exergy efficiencies are calculated for ...

  • Effects of combustion efficiency on an Otto cycle

    This paper explains how the combustion efficiency influence the performance of an irreversible Otto cycle under conditions of varying fuel-air ratio. The irreversibility of Otto cycle comes exclusively from the expansion and compression processes. It is assumed that some fraction of the fuel's chemical energy cannot be fully released inside the engine because of incomplete combustion. Amount of ...
