Abstract:

In this paper, the optimal and safe operation of a hybrid power system based on a fuel cell system and renewable energy sources is analyzed. The needed DC power resulting from the power flow balance on the DC bus is ensured by the FC system via the air regulator or the fuel regulator controlled by the power-tracking control reference or both regulators using a switched mode of the above-mentioned reference. The optimal operation of a fuel cell system is ensured by a search for the maximum of multicriteria-based optimization functions focused on fuel economy under perturbation, such as variable

Abstract:

In this paper, the air-fuel ratio regulation problem of compressed natural gas (CNG) engines considering stochastic L2 disturbance attenuation is researched. A state observer is designed to overcome the unmeasurability of the total air mass and total fuel mass in the cylinder, since the residual air and residual fuel that are included in the residual gas are unmeasured and the residual gas reflects stochasticity. With the proposed state observer, a stochastic robust air-fuel ratio regulator is proposed by using a CNG engine dynamic model to attenuate the uncertain cyclic fluctuation of the fre

It has been established that when the diesel engine is overloaded, the smokiness of the exhaust gases increases. This indicator is affected by the configuration of the unit, incorrectly selected operating mode, existing violations in the regulation and operation of the fuel equipment. The results of a comparative analysis of ways to increase the indicators of domestic and foreign-made diesel engines of tractors and cars, which are in the conditions of ordinary operation of Ukrainian enterprises of various forms of ownership, are presented. Changes in fuel efficiency indicators and environmenta

Abstract:

Masalah klasik pada mesin-mesin EFI lama adalah emisi CO dan HC yang cenderung tinggi. Sementara, jika pembakaran diatur dalam campuran miskin (lean mixture), torsi mesin terbaik tidak diperoleh. Untuk itu, artikel ini menyajikan studi eksperimen tentang variasi tekanan bahan bakar dalam fuel rail. Untuk mengatur tekanan, sebuah adjustable pressure regulator diterapkan untuk membuat tekanan awal 1,8 sampai 2,6Kg/cm² dengan interval 0,2. Hasilnya, emisi CO dan HC meningkat sesuai dengan peningakatan tekanan bahan bakar. Namun demikian, aplikasi adjustable pressure regulator pada mesin EFI

Abstract:

This study addresses the need for cleaner and more economical power solutions by developing a dual-fuel retrofit kit for a 2.0 kVA single cylinder spark ignition (SI) generator. The kit enables operation on petrol, LPG, or a blend, targeting emission reduction and improved fuel flexibility in off-grid and low-income settings. The system integrates a venturi-type mixer, zero-governor regulator, and delay-controlled dual solenoid valve, retrofitted without modifying the engine block or ignition system. Thermodynamic performance was evaluated under four discrete loads and three fuel modes, analys

Abstract:

Pepper is an important crop in Indonesia because it is one of the country's foreign exchange sources because it is one of the export commodities. The availability of good plant materials will support increased production. Provision of growth regulators in vegetative propagation is very influential on the propagation of pepper plants. The purpose of this study was to determine the most effective combination of growth regulators for pepper cutting. This study was conducted using a randomized block design consisting of eight treatments namely Control (P1), metallic 2 mL L-1 water (P2), mastafol 2

Abstract:

A zeolite-based catalyst modified with an active catalytic additive of chloroferrate, which is a weakly acidic regulator of the process activity, has been developed. The catalyst exhibits high activity in the process of catalytic cracking of fuel oil with the formationof light gaseous hydrocarbons and a wide range of liquid isomeric and aromatic hydrocarbons. The implementation of the process is accompanied by low coke formation. The use of the studied catalyst under relatively mild temperature conditions certainly allows us to speak about the possibilities for increasing the percentage of lig

Abstract:

This article presents the results of an experimental study made on a Toyota Hilux 2.400 cm3 motor, for determining the influence on environmental-mechanical performance (fuel consumption, volumetric efficiency, equivalence ratio, the concentration of CO and CH4) when the dimensions of the kit components are modified. The factors evaluated were: size of the regulator, diameter of the Venturi in a fixed mixer and its location (in the admission duct and on the carburetor). The motor was tested in five different operating conditions (secondary factor). The effect of the statistic factor on environ

Abstract:

The mammalian/mechanistic target of rapamycin (mTOR) is a key component of cellular metabolism that integrates nutrient sensing with cellular processes that fuel cell growth and proliferation. Although the involvement of the mTOR pathway in regulating life span and aging has been studied extensively in the last decade, the underpinning mechanisms remain elusive. In this review, we highlight the emerging insights that link mTOR to various processes related to aging, such as nutrient sensing, maintenance of proteostasis, autophagy, mitochondrial dysfunction, cellular senescence, and decline in s

Abstract:

In mid-1997 National Power, a major British electricity generator, received permission from the national environmental regulator, the Environment Agency, to test-burn petroleum coke blended with local coal at their Drax power station in North Yorkshire. Late in 1997 these tests were completed successfully, from the perspective of Drax, and the application for the full-scale burn of the blended fuel is expected to be made in 1998. The imported by-product of oil refining is considerably cheaper than local coal, but allegedly richer in several environmental pollutants. In spite of flourishing gre
