Betterment of ecological parameters of a diesel engine using Brown‘s gas

Abstract

Hydrogen could become an important element, allowing us to accumulate and transfer energy in a clean way. Hydrogen can be used in cars as a fuel additive which increases the combustion efficiency of the fuel-air mixture. A small amount of hydrogen gas could also be produced in a car by decomposing water by means of electrolysis, using for this purpose the energy produced by the car's electric power generator. The hydrogen and oxygen (HHO) mixture obtained, which is also known as Brown's gaseous mixture, is supplied to the engine's intake manifold. Tests have been performed with 1.6 TD (SB) diesel engine. The automobile was tested on a chassis dynamometer running at a different speed. The engine was tested using fuel-air combustion mixture and fuel-air-HHO gas combustion mixture without additional adjustment of the fuel supply system. The test results have revealed that additional injection of HHO gas into combustion mixture resulted in up increase of fuel consumption, but the CO, the HC, the PM amount has decreased insignificantly. At few engine loads the amount of NO x decreased, however increasing the engine load resulted in a gradual increase. Having analysed test results we came to a conclusion that additional supply of HHO gas into combustion mixture resulted in improvement of the combustion quality of fuel-air mixture and ecological performance of the engine. This is especially relevant for the automobiles which are not equipped with a supplementary exhaust gas toxicity decreasing system.

Research of Energy and Ecological Indicators of a Compression Ignition Engine Fuelled with Diesel, Biodiesel (RME-Based) and Isopropanol Fuel Blends

“…The start of the injection (SOI) was controlled by the Engine Electronic Control Unit (ECU) and it was a single injection strategy. Figure 1 presents a detailed image of the tested engine and its parts, while research conducted by other authors [52][53][54][55] and Table 2 lists the test engine parameters.…”

Investigation of Correlation Between Diesel Fuel Cold Operability and Standardized Cold Flow Properties

“…Based on the measurement of fuel consumption a new operational procedure (Lakatos, 2015) was suggested. Importance of emissions is highlighted in (Rimkus et al, 2013;Taritas et al, 2017;Szwaja et al, 2018;Juknelevicius et al, 2018) as well.…”

Development of a New Method for Comparing the Cold Start- and the Idling Operation of Internal Combustion Engines

“…There is a connection between the performance and the economic features, the elements of the system mutually affect one another (Burke, 1993;Al-Hasan, 2007;MacMillan, 2009;Rimkus et al, 2013) The value of fuel consumption projected to 100 km route significantly increases in case of urban traffic. 43(4), pp.…”

“…The cold start and the cold operational procedure of buses must be optimal both in the scope of environment protection and economic aspects (fuel consumption, wear and tear In case of applying diesel engines in motor vehicle operation, the dynamic characteristics of the engine are significant. There is a connection between the performance and the economic features, the elements of the system mutually affect one another (Burke, 1993;Al-Hasan, 2007;MacMillan, 2009;Rimkus et al, 2013) The value of fuel consumption projected to 100 km route significantly increases in case of urban traffic. …”
