“By April 1983 it was clear that Japan would be exporting automotive precombustion chambers in significant volume to U.S. car manufacturers.”
“In fact, Hitachi Metals, which had investment-casting experience in Japan, made inroads into the U.S. precombustion chamber market as early as 1981.”
“For instance, handguns and automotive precombustion chambers were very quality sensitive.”
“There are different kinds of carbon capture: precombustion usually refers to capturing CO2 from coal gasification (such as polygeneration, coal-toliquids, or IGCC) processes, post-combustion is associated with capturing carbon from the waste gases from conventional combustion (such as supercritical or ultra-super critical power plants), and oxy-fuel combustion is separation post oxygen-rich combustion.”
“It's complicated, of course, but Honda basically added a small auxiliary inlet valve to the normal intake and exhaust valves that filled a precombustion chamber near the sparkplug with a rich air/fuel mixture.”
“Compared with post-combustion processes, the pressure and concentration of CO2 in precombustion processes is relatively high - offering the potential to apply novel CO2 capture technologies such as membranes, solvents and sorbents.”
“CO2 precombustion capture at a coal gasifi cation plant in North Dakota, USA.”
“Hitachi’s and Hitchiner’s precombustion chambers were of comparable quality, and Hitchiner’s quoted price was slightly lower than Hitachi’s for one of the two models supplied.”
“For 1982 Hitchiner’s sales of precombustion chambers were $2.7 million, with around a 24% market share, a dramatic drop from 1981.”
