Abstract:

Laser ignition is considered to be one of the most promising future ignition concepts for internal combustion engines. It not only combines requirement of reduction of pollutant emissions but also improves engine efficiencies.  In general, a well-defined ignition location and ignition time is of great importance for an IC engine. Spark plugs are well suited for such tasks but suffer from disadvantages, like erosion of electrodes & inflexible or un-optimal location of spark plug. Also the conventional ignition system cannot burn leaner air fuel mixture properly. In order to overcome th

Homogeneous Charge Compression Ignition (HCCI) engines are considered an emerging internal combustion technology with significant potential for enhancing fuel efficiency and lowering emissions compared to traditional Spark Ignition (SI) and Compression Ignition (CI) engines. By igniting a homogeneous air-fuel mixture through compression without the need for a spark plug, HCCI engines achieve a more uniform and complete combustion process, resulting in lower NOx and particulate matter (PM) emissions. Despite these advantages, challenges such as limited control over combustion timing, susceptibi

Homogeneous Charge Compression Ignition (HCCI) is a cutting-edge combustion engine technology that merges the benefits of both diesel and gasoline engines. In HCCI engines, a uniform mixture of fuel and air enters the combustion chamber during the intake phase, which significantly lowers the average temperature within the chamber. This temperature reduction is crucial as it minimizes the formation of nitrogen oxides (NOx), pollutants that typically form at high temperatures, thus making HCCI engines more environmentally friendly.

Abstract:

This study conducts a simulation analysis of the performance and emission characteristics of a biogas-fueled engine using the thermodynamic simulation tool AVL Boost. The original diesel engine model was modified by lowering the compression ratio and enhancing mixture formation to enable operation with biogas. Key engine parameters such as airflow mass, brake torque and power, fuel consumption, emission outputs, and in-cylinder parameters were evaluated. The simulation results indicate that, under biogas operation, NOx emissions decrease significantly, while CO emissions rise compared to diese

Abstract:

The article presents synthetically the methods of ignition of the air-fuel mixture in Internal Com-bustion (IC) engines along with the characteristics of their advantages and disadvantages, the problems of their use and the possibility of development. The further development of piston engines will require a drastic reduction in the emission of harmful exhaust components and carbon dioxide, which is the most important greenhouse gas emitted by IC engines. For this reason, not only the engines themselves must be changed but fuels as well. For the most effective use of them, self-ignition of a ho

A novel fully hydraulic variable valve system is described in this paper, which achieves continuous variations in maximum valve lift, valve opening duration, and the timing of valve closing. The load of the unthrottled spark ignition engine with fully hydraulic variable valve system is controlled by using an early intake valve closing rather than the conventional throttle valve. The experiments were carried out on BJ486EQ spark ignition engine with fully hydraulic variable valve system. Pumping losses of the throttled and unthrottled spark ignition engines at low-to-medium loads are compared a

Abstract:

Two-stroke spark ignition engines are widely used in Unmanned Aerial Vehicles. Aviation kerosene offers advantages over aviation gasoline due to its higher flash point and lower volatility, making it likely to be adopted more widely in the future. However, the poor evaporation and atomization characteristics of aviation kerosene result in suboptimal ignition performance, especially in the engine start-up phase. To explore the fitting mixture concentration and temperature conditions for achieving better ignition performance of aviation kerosene, A series of experimental studies are conducted on

Ammonia is a very promising alternative fuel for internal combustion engines, but there are some disadvantages, such as difficulty in ignition and slow combustion rate when ammonia is used alone. Aiming to address the problem of ammonia combustion difficulty, measures are proposed to improve ammonia combustion by blending hydrogen. A one-dimensional turbocharged ammonia-hydrogen engine simulation model was established, and the combustion model was corrected and verified. Using the verified one-dimensional model, the effects of different ratios of hydrogen to ammonia, different rotational speed

Pollution reduction in urban areas is a major driving force to upgrade mass transportation systems. Options to the urban planner include electric traction and combustion engine upgrade. Electric traction centralizes the emission source, usually removed from urban areas, but requires substantial capital costs and lead time for the transportation infrastructure. Engine emission improvement is possible through both fuel changes and engine upgrade. Natural gas engines are a viable option for clean-operating urban buses.
