Abstract:

The pioneering research works on the high pressure fuel injection and the pilot injection
technologies are introduced to overview the pathway of the engine emission technology development in Japan.
In the first decade of the 21 century, the diesel engine technology realized an ideal combustion as an internal
combustion engine, like exhaust gas regeneration (EGR) lean burn combustion. Another breakthrough was
made in new after treatment systems. The real world problems of the after treatment are discussed in pursuance
of further improvement. Since the diesel passenger car market is small in Japan, the diesel engine technology
development has mostly been driven by commercial vehicle engine technologies. However, driving conditions of
commercial vehicles (trucks and buses) and the sulphur content in fuel are different in different countries. These
factors significantly affect diesel emission control strategies and design.

Key words: diesel combustion, technology development, Japan, exhaust gas recirculating (EGR), selective
catalytic reduction (SCR), diesel particulate filter (DPF), premixed compression ignition (PCI)
