This is due to raw, externally premixed fresh charge comprising air, fuel and lube oil being short-circuited into the exhaust during the scavenging process. Even with the move to four-stroke engines, additional complexity will be necessary—possibly exhaust after-treatment—in order to fully meet regulations.

The Japanese firm, said to be first to turn out portable fuel cells on such a scale, is installing an assembly line at a Yokohama facility. The current returns to the fuel cell cathode (air side); Protons (H+) and electrons (e-) react with the air at the cathode to form humid air, which is exhausted from the system.

Current Clean Air Act (CAA) standards (Tier 1) for new Category 3 compression-ignition marine engines (marine diesel) at or above 30 liters per cylinder displacement have been in effect since January 2004 and are equivalent to the current international standards for marine engines contained in MARPOL Annex VI (which went into effect in 1997).

Key changes to implement the integrated cycle are isothermal compression and heat addition from the exhaust gas to the charge air after the end of compression. To transfer exhaust gas heat at the end of compression requires the use of a “split cycle” in which the standard four-stroke sequence is split into two separate elements.

Alternatively they can serve as buffers for renewables such as wind and solar power—whether as part of the grid or as home installations. Installation of CCS charging stations has already begun in Europe and the United States. Because the exhaust system transports only water, it can be made of lightweight polymer.

And when operating in EV mode at speeds up to 30mph, it uses no fuel and produces zero exhaust emissions. Adopting the Atkinson cycle and a new, cooled exhaust gas recirculation system brings significant gains in fuel efficiency and emissions reduction. As a result the exhaust temperature is lower than that of conventional engines.
