Measurement and Analysis of lubricant oil consumption in a single cylinder hydrogen IC engine
… LOC measurement method of a hydrogen combustion single cylinder test engine. This method utilizes an FTIR device to measure carbon dioxide in the exhaust gas. Since hydrogen is not a carbon-based fuel, its combustion reaction does not yield carbon dioxide. The only source of carbon in the system …
