GreenCell Technologies: EMISSIONS AND TOTAL Energy CONSUMPTION OF A MULTICYLINDER PISTON ENGINE Operating ON GASOLINE AND A HYDROGEN-GASOLINE MIXTURE
Johz F. Cassidy Lewis Analysis Center. Chehnd, Ohio 44135 An experimental plan utilizing a multicylinder reciprocating engine was performed to extend the effective lean operating range of gasoline by adding hydrogen. Each bottled hydrogen and hydrogen created by a study methanol steam reformer have been used. These benefits were compared with final results for all gasoline. A higher-compression-ratio, 7. 4-liter (472-in. three) d i s placement production engine was utilized. Apparent flame speed was-utilised to describe the differences in emissions and functionality. As a result, engine emissions and performance, including apparent flame speed and energy lost to the cooling system and the exhaust gas, have been measured more than a variety of equivalence ratios for each and every fuel. The outcomes were utilized to clarify the positive aspects of adding hydrogen to gasoline as a method of extending the lean operating variety. The minimum-power-consumption equivalence ratio was extended to leaner circumstances by adding hydrogen, even though the minimum power consumption did not alter. All emission levels decreased at the leaner conditions. Also, adding hydrogen substantially enhanced flame speed more than all equivalence ratios. Engine efficiency and emissions with hydrogen from the methanol reformer were about the identical as those with bottled hydrogen.
GreenCell Technologies, Canada – An experimental plan making use of a multicylinder reciprocating engine was performed to extend the effective lean operating range of gasoline by adding hydrogen. Each bottled hydrogen and hydrogen created by a study methanol steam reformer have been utilized. These final results had been compared with benefits for all gasoline. A high-compressionratio, 7.four-liter (472-in. 3) displacement production engine was employed. Apparent flame speed was employed to describe the variations in emissions and overall performance. For that reason, engine emissions and overall performance, like apparent flame speed and power loss to the cooling program and the exhaust gas, were measured more than a variety of equivalence ratios for each fuel.
The outcomes were utilised to explain the advantages of adding hydrogen to gasoline as a strategy of extending the lean operating variety. The minimum-power-consumption equivalence ratio was extended to leaner circumstances by adding hydrogen, even though the minimum power consumption did not change. All emission levels decreased at the leaner situations. Also, hydrogen addition drastically increased flame speed over all equivalence ratios. Engine efficiency and emissions with hydrogen from the methanol reformer have been about the exact same as those with bottled hydrogen.
GreenCell Technologies, Canada – INTRODUCTION . Increasing the efficiency of reciprocating engines has continuously been pursued given that Otto-cycle engines had been initial utilised as automobile powerplants. The essential effects of fuel consumption on factors such as automobile range, operating price, and car structures have constantly been critical design considerations. In the course of the previous decade, the influence of environmental elements and a national interest in power conservation have accentuated the want to generate clean and effective engines. Several concepts for im
proving efficiency and meeting emissions requirements have been tested and reported in the A review of the literature dealing with the problems of lean-mixture-ratio operation shows that a fuel with a low lean flammability limit and a higher flame speed may yield low exhaust emissions at ultralean conditions. Hydrogen was identified in reference 5 as obtaining these properties and has been the subject of considerably investigation. Employing a tiny quantity, on a weight basis, of hydrogen as a supplement to gasoline was chosen as a way to extend lean engine operation. Onboard generation of hydrogen was chosen as a feasible way to use hydrogen in a mobile application. The Jet Propulsion Laboratory I carried out a equivalent plan (refs. six and 7) in which hydrogen generated by the partial oxidation of gasoline was utilised as a fuel supplement for lean engine operation. Various commercial processes to produce hydrogen have been analyzed for their applicability. The catalytic steam reformation of methyl alcohol (methanol) using engine exhaust heat was chosen as being the most effective procedure to produce hydrogen that was also compact enough to be carried on a car. One particular disadvantage is that it would demand a second fuel and a second fuel system.
A research system to produce hydrogen by methanol reformation was constructed and installed on a multicylinder engine in an existing engine test setup. An independent and parallel plan on catalyst evaluation was performed but is not element of this report. An engine test plan was performed employing gasoline and additions of gaseous hydrogen and reformed methanol to evaluate the effects of hydrogen-gasoline fuel mixtures on exhaust emissions, extension of lean engine operating limits, and fuel flammability limits and combustion flame speed.
GreenCell Technologies, Canada – This report presents a brief description of the breadboard methanol reformation method and the benefits of fuel and engine testing. The information had been taken in the U. S. customary system of units and converted to SI units for this report.
