The primary aim of this study is to alternate between conventional fossil fuels and reduce the emissions greenhouse gases sulphur dioxide from diesel engine. In current study, in order mitigate NOx emissions, EGR technique was implemented utilizing hybrid biodiesel at three varying proportions 5%, 10% 15% an optimum compression ratio 20:1. findings demonstrate that for a alternative 20:1 fully ...

Continued legislative pressure to reduce exhaust emissions from CI (compression ignition) has resulted in the development of advanced fuel injection equipment. This advanced injection system produces higher temperatures and pressures at the injector tip, where deposit formation is initiated. In this research, an endurance test was carried out for 250 h on 2 fuel samples; DF (diesel fuel) as bas...

Vegetable oils are renewable in nature and can be directly used as fuels in diesel engines. However, their high viscosity and poor volatility lead to reduced thermal efficiency and increased hydrocarbon, carbon monoxide and smoke emissions. Transesterification is one of the methods by which viscosity could be drastically reduced and the fuel could be adopted for use in diesel engine. This Ester...

During short term engine operation, renewable fuels derived from vegetable oils, are capable of providing good engine performance. In more extended operations, some of the same fuels can cause degradation of engine performance, excessive carbon and lacquer deposits and actual damage to the engine. Moreover, temperatures in the area of the injector tip due to advanced diesel injection systems ma...

Alarming situation of world fossil fuel and environment degradation has been stimulating the researchers and engineers to find new sources of fuel, which must be renewable, economically available and environment friendly. In this regard biodiesel has one of the most substantial alternative renewable fuels for diesel engine. Biodiesel has made from different feedstock depending on the availabili...

Water-in-diesel (W/D) emulsion fuel is a potential alternative that can simultaneously lower NOx exhaust emissions and improves combustion efficiency. Additionally, there are no additional costs or engine modifications required when using W/D fuel. The proportion of water added speed crucial factors influencing behavior. This study aims to examine the impact diesel on performance pollutant comp...

The aim of this work was to study the combustion, performance, and emission characteristics of a 5.5 kW four-stroke single-cylinder water-cooled direct-injection diesel engine operated with blends of biodiesel-like fuel (BLF15, BLF20 & BLF25) obtained from a 50:50 mixture of transesterified waste transformer oil (TWTO) and waste canola oil methyl esters (WCOME) with petroleum diesel. The mixtur...

The organic Rankine cycle (ORC) can be used to recover the waste heat from a stationary compressed natural gas (CNG) engine. However, the exhaust energy rate varies with engine load, which can influence the operating performance of the ORC system, therefore, it is necessary to study the running state of the ORC system. In this paper, first, the numerical simulation model of the ORC system is bu...

A direct injection (DI) diesel engine is tested with different biodiesel-diesel blends, such as B0 (neat diesel), B5 (i.e., 5 vol. % biodiesel and 95 vol. % diesel), B10 (10 vol. % biodiesel), B20 (20 vol. % biodiesel), B50 (50 vol. % biodiesel), and B100 (neat biodiesel) for performance and emissions under different load conditions. Engine performance is examined by measuring brake specific fu...
