“…Hydrogen's greater heating value and extra oxygen in biofuel raise in-cylinder temperature and pressure, which increases NO emission. 9,21 DEE at 20% with KOME + 10LPM H 2 decreases NO emissions, which is the better solution to overcome the drawback of hydrogen induction without involving any post-treatment in the exhaust. At full load, NO emissions for diesel, KOME100, KOME100 + 8LPM H 2 , KOME100 + 10LPM H 2 and KOME100 + 10LPM H 2 + 20%DEE are 1698, 1466, 1752, 1827 and 1890 ppm, respectively.…”

“…Dhanasekaran and collegues 9 used a 3.5 kW CI engine that operated on both diesel and hydrogen, as the fuels to investigate the effect of DEE as an ignition enhancer. In addition to diesel in the primary injections, they asserted when DEE and hydrogen are added to the air intake manifold, would improve combustion and lower NOx emissions for the 0.00142 g/m of DEE injections and 7 LPM of hydrogen induction.…”

Kapok oil methyl ester (KOME) is used as a pilot fuel, while hydrogen and diethyl ether (DEE) are used as secondary fuels to improve the performance, emissions and combustion of a direct injection compression ignition engine. With a compression ignition engine, a slight modification to the system enables hydrogen gas through the intake manifold. A flow metre limits the quantity of energy the hydrogen may produce off, and two flame arresters prevent backfires in the fuel line. At full load and maximum hydrogen energy sharing, KOME + 20%DEE obtained a brake thermal efficiency of 30.31%, which is 14% higher than without hydrogen enrichment and about 8% higher than diesel's value (0% hydrogen energy share). The main problem with previous research is that hydrogen with a high heating value makes greater amounts of nitric oxide. Diethyl ether, on the other hand, has fixed this major problem, and the absence of carbon in hydrogen fuel lowers CO, HC and smoke emissions.

“…Flashback arrestor was used to restrain or shuts off gas flow and extinguish the flame before it can reach gas source when undesirable combustion phenomenon occurs [25]. The various non-reverse control valve was set up in fuel supply line to stop the backflow of gasses to the engine cylinder (see Fig.…”

The comprehensive parameters of a dual-fuel engine for special heavy vehicles directly reflect vehicle performance. This paper takes the Yuchai YC6K420 series of inline six-cylinder CNG/dual fuel engine special heavy-duty vehicles as an example to build the comprehensive parameter test system for the engine. The PXI 6251 capture card is used to acquire engine analog signals. The fuel consumption and gas consumption meters of three German Endress + Hauser (E + H) companies are combined to measure, display and store fuel consumption and gas consumption data. The system data acquisition program mainly includes channel creation, configuration and signal acquisition, which can realize system data reading, filtering conditioning, display and save. The electronic control unit in the system uses the periodic interrupt to send and receive data, and analyzes the data transmitted by the CAN communication module of the controller area network through the data feedback function. The data is restored to its true value and displayed graphically. The test results show that the system can effectively detect the temperature of the vehicle's dual fuel engine. At the same time, it can be learned that the in-cylinder combustion of the dual fuel engine is relatively flat, and the maximum combustion heat release rate is relatively low; when the load and the rotational speed are low, the combustion duration is relatively long. Keeping other conditions constant, reducing only the nozzle flow area is not conducive to improving the combustion characteristics of the dual fuel engine.
