On the basis of introducing the origin and development of finite time thermodynamics (FTT), this paper reviews the progress in FTT optimization for internal combustion engine (ICE) cycles from the following four aspects: the studies on the optimum performances of air standard endoreversible (with only the irreversibility of heat resistance) and irreversible ICE cycles, including Otto, Diesel, A...

In recent years, hybrid electric vehicles (HEVs) have increased significantly due to climate change and the demand for high-efficiency power sources. HEVs that combine an internal combustion engine (ICE) motor (EM) can improve output of ICE overcome challenges insufficient battery life vehicles. this study, a parallel HEV with distribution mechanism is developed energy saving carbon reduction. ...

Spark-ignited internal combustion engines have evolved considerably in recent years in response to increasingly stringent regulations for emissions and fuel economy. One new advanced engine strategy ustilizes high levels of exhaust gas recirculation (EGR) to reduce combustion temperatures, thereby increasing thermodynamic efficiency and reducing nitrogen oxide emissions. While this strategy can...

The goal of this project is to provide a compact and efficient fluid power source for mobile applications (10 kW-500 kW), including on-road vehicles and off-road heavy machineries. This is achieved through the development of a hydraulic free-piston engine (HFPE). Previously, a virtual crankshaft mechanism is proposed by the authors which regulates the pistons to follow any reference trajectorie...

Support of the established technical characteristics engines is reached by its regular service and diagnostics in particular - existence diagnostic programs built onboard computer car which carry out constant control main parameters engine.Based on algorithm vibroacoustic diagnostics, a system vibration internal combustion engine (ICE) proposed, can be integrated into intelligent environment se...

increase of environmental pollution and restricted emission legislations have forced companies to produce automobiles with lower air pollutants. in this respect, discharge of blowby gases into the environment has been prohibited and their recirculation into the combustion chamber is proposed as an alternative solution. in addition, using egr technique to control and reduce nitrogen oxides in in...

In the current study, a 0D/1D engine model built in commercial code GT-Suite was coupled with Electronic Control Unit (ECU) created Simulink environment, aiming to more accurately predict interaction of and aftertreatment system (ATS) operating parameters, both during steady-state transient maneuvers. After detailed validation based on extensive experimental data from heavy-duty diesel Internal...

In order to comply with the increasingly tough emission standards worldwide, engine manufacturers are forced not only to substantially reduce emissions of particulate matter (PM), but also emissions of nitrogen oxides. The main approach pursued by MTU is low-emission combustion, in other words an internal engine solution. However, this means taking into account a basic principle that governs th...

The invention of the spark-ignited internal combustion engine provided a market for a petroleum middle distillate, gasoline, about 100 years ago. The internal combustion engine and gasoline have co-evolved until motor vehicles now annually consume about 110 billion gallons of gasoline in the United States. Continuing air pollution problems and resulting regulatory pressures are driving the need...
