TL;DR: In this paper, an electrically heating catalytic apparatus that quickly heats catalyst to an activation temperature even when the engine is started at a low temperature below the catalyst activation temperature was presented.
Patent
Piezoelectric low-pressure fuel injector
TL;DR: In this article, a reed valve is used in a piezoelectric fuel injector for high-frequency drive signal to ensure precise metering of fuel quantity over a wide range of engine operating conditions.
Patent
Diesel engine fuel injection system with a rate-of-injection control arrangement
TL;DR: In this paper, a variable volume chamber and a pumping chamber of the pump are intermittently connected by a passage which is specifically designed in such a manner that the fluid communication between the chambers, during the delivery stroke of a pump plunger, is provided only for an initial stage of a delivery stroke.
Patent
Electrostrictive actuator device and fuel injection device using same
Toshihiko Igashira,Yasuyuki Sakakibara,Seiko Abe,Kiyonori Sekiguchi,Izawa Akihiro,Hisasi Kawai +5 more
TL;DR: An electrostrictive actuator which can be used, e.g., in a distributor type fuel injection device of a diesel engine, has an electrostriches for generating an electric charge upon reception of a load and an electric circuit unit connected to the electrostrics.
Patent
Electrically heatable catalytic converter
TL;DR: In this paper, an electrically heatable catalytic converter for internal combustion engines is provided, which includes a honeycomb multi-layered core member wound around an electrode, which is used to prevent the core from telescoping in the direction of exhaust gas flow during high-load engine operation.
