Physical and chemical phenomena of reducing carbon deposits with hydrogen-oxygen gas

Context HHO carbon-cleaning is the process of removing carbon deposits from the internals of the combustion engine and the exhaust tract – DPF, EGR valve, Catalyst, etc. – by means of adding a mixture of gaseous Hydrogen and Oxygen (HHO gas) into the engine air-intake manifold. The goal of HHO carbon-cleaning is to reduce the […]

Experimental comparison of pure hydrogen and HHO (hydroxy) enriched biodiesel (B10) fuel in a commercial diesel engine

Highlights Effects of H2 and HHO to performance and emissions of a diesel engine are examined. Fossil fuel dependency reduced at volumetric ratio of 10% by using biodiesel. Fuel pump plunger pin was re-set and diesel fuel injection has been decreased. In terms of exhaust gas emissions, H2 + B10 provided better results than HHO + B10. Engine performance […]

Engine performance, emissions characteristics of the compression ignition engine using HHO gas (Brown’s gas)

Abstract HHO gas (Brown’s gas) has recently been used as a new source of energy. The study presents the experimental results at 50% of the accelerator pedal when installed hydroxy (HHO) gas generator on 490 QZL diesel engines. HHO gas was provided into the engine manifold. Comparing the experimental results found that: the economic, technical […]
