Dual-fuel gas-diesel engines present an environmentally attractive substitute for conventional diesel engines that …, in which the gaseous fuel is used as a primary fuel while the diesel fuel is used as an ignition source, suffers from …

A single-cylinder diesel engine has been converted into a dual-fuel engine to operate with natural gas together with a … pilot injection of diesel fuel used to ignite the CNG–air charge. The CNG was injected into the intake manifold via a gas …

) of a dual-fuel diesel engine (H2 (hydrogen)–diesel) using exergy analysis. The maximum available work increased with H2 … mixing and friction irreversibility. The maximum available work of the diesel engine at rated load increased from 29% with … including exhaust gas recirculation and turbo charging on maximum available work and energy efficiency of diesel engines. …

A CFD (computational fluid dynamics) study was conducted on a diesel engine (7.4kW) under dual-fuel mode (diesel …–CNG (compressed natural gas), and diesel–H2 (hydrogen)) for optimization of gas injector orientation (location and angle). The …

This study investigates the effect of ambient oxygen concentration on biodiesel and diesel spray combustion under … a longer premixed-combustion duration. The 18% ambient O2 condition works better for biodiesel than diesel in reducing … soot luminosity. With 12% O2, diesel combustion is significantly degraded. However, both fuels experience low temperature …

-connected petrol generator; the same system operating as a stand-alone system, and; a 6kWe diesel generator, all modelled against the …-in-tariff subsidies, and also the displacement of mineral diesel with biodiesel. The results quantify technical outputs of the systems and …

similar to that of diesel. Waste plastic oil (WPO) was tested as a fuel in a D.I. diesel engine and its performance … characteristics were analysed and compared with diesel fuel (DF) operation. It is observed that the engine could operate with 100 …% waste plastic oil and can be used as fuel in diesel engines. Oxides of nitrogen (NOx) was higher by about 25% and carbon …

This paper presents the impact of oxygen and nitrogen compounds on the lubrication properties of low sulfur diesel …-carboxylic acids on the tribological behaviour of the steel-on-steel systems, lubricated with low sulfur automotive diesel fuel …

The diesel fuel was mixed with the rice husk bio-oil using some emulsifiers based on the theory of Hydrophile …-Lipophile Balance (HLB). The lubricity of the bio-oil/diesel fuel blend was studied on a High Frequency Reciprocating Test Rig (HFRR … than that of the Chinese conventional diesel fuel (number zero). However, the anti-corrosion and anti-wear properties of …

An efficient way to decrease the CO2 emissions is the replacement of gasoline passenger cars (PC) by diesel ones, which … emit less CO2. This can be more effective in Greece where the percentage of new diesel PC remains less than 1%, contrary to … the other countries of the European Union, which have high diesel penetrations. The benefit of CO2 emitted from new PC is …
