摘要： In an air-fuel ratio feedback control system including at least one air-fuel ratio sensor downstream of a catalyst converter provided in an exhaust gas passage, an actual air-fuel ratio is controlled in accordance with the output of the downstream-side air-fuel ratio sensor. When at least one of the air-fuel ratio feedback control conditions for the downstream-side air-fuel ratio sensor is not satisfied the controlled air-fuel ratio is made an air-fuel ratio by an open loop control, while all the air-fuel ratio feedback control conditions for the downstream-side air-fuel ration sensor are satisfied the controlled air-fuel ratio is made the stoichiometric ratio (.lambda.=1) in accordance with the output of the downstream-side air-fuel ratio sensor. For a period after all the air-fuel ratio feedback control conditions for the downstream-side air-fuel ratio sensor are satisfied, the control by the output of the downstream-side air-fuel ratio sensor is prohibited, but, the controlled air-fuel ratio is made the stoichiometric ratio (.lambda.=1) by an open loop control or by the output of an upstream-side air-fuel ratio sensor.

摘要： An altitude compensation valve assembly comprising a housing structure having a bellows and a check valve unit. The check valve unit is supported for movement between a closed position, where communication between a fluid under pressure introduced into an inlet port of the valve assembly is discommunicated from the atmosphere, and an opened position where such communication is established. The check valve unit is normally biased towards the closed position and is moved towards the opened position when the pressure introduced through the inlet port exceeds a predetermined value determined in consideration with change in a altitude in which the valve assembly is operated to compensate for reduction in pressure resulting from change in altitude.

摘要： Disclosed is an internal combustion engine comprising a carburetor and a secondary air feed control valve for feeding secondary air into the exhaust system of the engine from the air pump driven by the engines. The engine further comprises a temperature detector for indicating whether the warm-up of the engine is completed, and a gear position detector for indicating whether the shift gear of the transmission of the engine is in the top gear position. A relatively lean air-fuel mixture is fed into the cylinder of the engine and a relatively small amount of secondary air is fed into the exhaust system when the shift gear of the transmission is in the top gear position after completion of the warm-up of the engine.

摘要： An exhaust gas recirculation control valve for a diesel engine. The valve comprises a valve casing of a rectangular cross-sectional shape disposed in the intake line of the engine. A valve seat connected to an exhaust line of the engine via an EGR passageway is formed in a side wall of the rectangular-shaped valve casing. A valve member is arranged in the casing and then rotated about an axis located upstream of the valve seat in such a manner that the valve member is moved between a position wherein valve member closes the valve seat and another position wherein the plate closes the intake passageway. The valve member comprises a base portion of a flat shape and a guide portion which is inserted into the valve seat when the degree of opening of the valve member is small.
