    摘要: In a turbine rotor composed of a ceramic turbine blade and a metal shaft with an end to be machined, martensite stainless steel or martensite heat-resistant steel which can be hardened in a gas or vacuum after having been heated beyond the quenching temperature thereof is used as the metal. The ceramic blade and the metal shaft are heat-connected by brazing or shrinkage fit at 800.degree. C., or more. The metal shaft hardened through the heat-connection is tempered only at the end to be machined or the metal shaft heated to the quenching temperature is quench hardened only in part other than the end to be machined, thus facilitating the machining of the metal shaft locally which keeping the remaining part thereof in a quench hardened condition.

    摘要: An adjustment mechanism for a ceramic rocker arm. The ceramic rocker arm is formed with a smooth bored opening through the adjustment end of the rocker arm. An externally threaded adjusting shaft is passed through the opening and an internally threaded locking member such as a locking nut is disposed on the shaft and engaged on the external threads. An internally threaded member is disposed to engage the external threads of the shaft and also engage the adjustment end of the rocker arm.

    摘要: A turbocharging system for an internal combustion engine improves performance and efficiency under low-speed, high-load operating conditions by adding secondary air to the exhaust gas upstream of the turbocharger. The secondary air combusts with unburned fuel contained in the exhaust gas to increase the temperature and pressure of the exhaust gas driving the turbocharger. Secondary air is added only when the exhaust gas temperature is above a prescribed temperature and the air-fuel ratio of the exhaust gas is below a prescribed ratio.

    摘要: A turbine having an improved connection between a ceramic rotor and a metal turbine shaft. The juncture between the rotor and the turbine shaft is disposed between a bearing supporting the turbine shaft and a sealing ring isolating the rotor from the oil reservoir of the turbine. A groove is formed at the juncture. Oil is allowed to circulate around the groove at the juncture between the rotor and the shaft, thereby providing a lowered temperature of the juncture, and hence preventing separation between the rotor and shaft due to differences in coefficients of thermal expansion.
