摘要： At the time of a stop of an engine, a diagnostic control unit shuts off a purge line with a purge control valve and an atmospheric port of a canister with a drain cut valve, and thereby holds an evaporative emission control circuit inclusive of a fuel tank and the canister in a state of a closed space during an off period of the engine. At the time of a next start of the engine, the diagnostic control unit measures a pressure in the closed circuit with a pressure sensor and checks a pressure decrease due to condensation of fuel vapors in the closed circuit to determine the existence or nonexistence of leakage.

摘要： An evaporative emission control system is provided which includes a bypass valve, purge control valve and a vent control valve. To make a leak diagnosis, firstly the vent control valve is closed while the purge control valve is opened, whereby to negatively pressurize the inside of a fuel vapor conduit portion extending from the bypass valve to an intake pipe side. After the pressure in the fuel vapor conduit portion from the bypass valve to the intake pipe is reduced to a predetermined value, the purge control valve is closed. Then, the bypass valve is opened, and after lapse of a predetermined time from the opening of the bypass valve a variation of pressure in a conduit extending from the fuel tank to the purge control valve is asured. Based on the variation of pressure, a leak diagnosis is made. By this, the evaporative emission control system can prevent the fuel vapor in the fuel tank from being drawn into the intake pipe during reduction of pressure in the conduit and thus causing unstable operation of an engine.

摘要： There is provided an apparatus for detecting a leak in an evaporative emission control system for an internal combustion engine including a fuel tank, a canister for collecting fuel vapors from the fuel tank, and a purge control valve disposed between the canister and the intake pipe for allowing flow of the fuel vapors from the canister to the intake pipe such that a fuel vapor flow passage is provided which extends from the fuel tank to the purge control valve by way of the canister. The apparatus comprises a vent control valve for selectively opening and closing an atmospheric vent of a canister, an actuating device for actuating the purge control valve and the vent control valve to fully close immediately after the engine starts and thereby closing the fuel vapor flow passage in a way as to prevent communication between an inside and outside of the fuel vapor flow passage, a pressure sensor for detecting a pressure in the fuel vapor flow passage, and a diagnostic device for detecting a leak on the basis of the pressure in the fuel vapor flow passage which reduces with increase of consumption of fuel in the fuel tank after the fuel vapor flow passage is closed.

摘要： An apparatus for use with an internal combustion engine having a fuel vapor trap from which fuel vapor is purged into the engine through a purge passage having a purge control valve provided therein. The purge control valve is controlled to permit fuel vapor purge through the purge passage based on the existing engine operating conditions. An air/fuel ratio feedback control correction factor is calculated to correct the air/fuel ratio within a predetermined range based on the air/fuel ratio of the mixture supplied to the engine. A gain value is calculated based on a deviation between the air/fuel ratio feedback correction factor calculated with the fuel vapor purge and the air/fuel ratio feedback correction factor calculated without the fuel vapor purge and a purge rate of the fuel vapor flow rate to the intake air flow rate. The calculated gain values are stored in a memory in respective memory locations addressable by different fuel vapor amounts. The calculated gain value is stored in the memory in a memory location corresponding to the sensed fuel vapor amount to update a gain value stored previously in the memory location. A gain value is read from the memory location corresponding to the fuel vapor amount. The amount of fuel supplied to the engine is controlled according to a target value calculated based on the read gain value and the engine operating conditions.

摘要： A rotary machine, such as a horizontally oriented scroll type refrigerant compressor is disclosed. The compressor includes a compressor housing, an inner block fixedly disposed within the compressor housing, a drive shaft extending substantially in the horizontal direction, and a driven mechanism, such as a compression mechanism operatively connected to one end of the drive shaft. The drive shaft is rotatably supported by the inner block and the compressor housing. A shielding element, such as an annular cylindrical member is fixedly held between the inner block and the compressor housing to prevent the drive shaft from passing through an oil sump of the housing. An internal lubrication oil pump is formed by the elements which are associated with the drive shaft, and is operated by virtue of the rotational motion of the drive shaft in order to supply the lubrication oil from the oil sump to the frictional surfaces of the internal component parts of the compressor. According to the construction and operational manner of the oil pump, the oil pump can be used for various types of horizontally oriented rotary machines. The drive shaft can also rotate without receiving oil viscous drag.
