A valve actuating apparatus for an internal combustion engine selectively operating in the normal Otto cycle or the Miller cycle is provided which enables the engine to achieve stable combustion and improved fuel economy during cruising or in a low-load engine operating region. A delayed-closing cam for Miller cycle operation and a normal cam having a cam profile for earlier valve-closing timing of the intake valve than a cam profile of the delayed-closing cam are provided on a camshaft. A cam profile-switching mechanism switches between the delayed-closing cam and the normal cam, for opening and closing the intake valve. An ECU controls the switching mechanism such that when a detected operating condition of the engine indicates starting or idling, the intake valve is operated by the normal cam, and when the detected operating condition indicates cruising, the intake valve is operated by the delayed-closing cam.

There is provided a control system for an internal combustion engine, which is capable of meeting a driver's demand of torque, and achieving high combustion efficiency and high emission-reducing performance by a three-way catalyst in lean-burn operation in a compatible manner. The control system sets a control amount indicative of either an oxygen mass supplied to a combustion chamber or a fuel injection amount such that oxygen concentration in exhaust gases becomes equal to a value corresponding to stoichiometric combustion. A target value corresponding to a demanded torque is set based on detected engine operating conditions. A degree of opening of a main throttle valve and a degree of opening of a sub-throttle valve in a passage by passing an intake passage equipped with a nitrogen-enriching device are controlled such that the control amount becomes equal to the set target value.

Ammonia refrigerating apparatus

The present invention provides a lubricant for a compression type refrigeration system using ammonia as a refrigerant, which comprises polyether compounds and aromatic amine compounds or phenothiazine compounds, and preferably further comprises alcohol compounds such as polyhydric alcohol partial ether and/or benzotriazole compounds. Further, the present invention provides a working fluid composition comprising the lubricant and an ammonia refrigerant, and a refrigeration system which is filled with the working fluid composition. The lubricant has not only good compatibility with ammonia, but excellent stability and lubricating property, and therefore can suitably used in a compression type refrigeration system using an ammonia refrigerant that does not have the possibility of ozone layer depletion and global warming phenomenon.

An EGR control system for a direct injection spark ignition engine operated at a plurality of the combustion modes comprising stratified-charge combustion and premix-charge combustion. The system includes a flow rate control valve equipped at the EGR passage to regulate flow rate of the exhaust gas to be recirculated which is operated when the one combustion mode is determined to be changed to another of a plurality of the combustion modes, thereby ensuring an EGR amount that is neither deficient nor excessive for the combustion mode, while preventing misfire from happening and preventing the degradation of drivability, fuel economy and emission performance from occurring. Alternatively, the system includes an actuator for regulating an opening of a throttle valve or a second EGR control valve installed in a branch passage and a passage switching valve for switching the EGR passage and the branch passage.

A gasoline direct-injection engine includes a cavity provided in a top portion of a piston and constituting a portion of a combustion chamber defined between a cylinder head and the top portion of the piston, a fuel injection valve mounted in the cylinder head for injecting gasoline directly into the combustion chamber, and a spark plug also mounted in the cylinder head to face the combustion chamber. In this gasoline direct-injection engine, the fuel injection valve facing a substantially central portion of a ceiling surface of the combustion chamber is mounted in the cylinder head to have an axis substantially parallel to an axis of the piston, and the cavity provided in the top portion of the piston and disposed below the fuel injection valve and the spark plug is defined so that it is deeper in an area corresponding to the spark plug than in an area corresponding to the fuel injection valve. Thus, it is possible to achieve a stable lean laminar burn in wide ranges of rotational speed and load of the engine, thereby providing an improvement in fuel consumption and an enhancement in nature of an exhaust gas.

An internal combustion engine includes a valve operating device operatively connected to a pair of intake valves and capable of opening and closing one of the intake valves in accordance with the operating condition of the engine and opening and closing the other intake valve in a small lift amount, thereby producing a deflection of the intake air drawn into the combustion chamber, and a fuel injection valve for injecting a fuel toward the pair of intake valve bores that are independently opened and closed by the intake valves, respectively. The timing of the opening and closing of the intake valve that is opened and closed only in the small lift amount is set at a time point such that the lift amount is maximized in the first half of the intake stroke of the piston. This promotes the atomization of the fuel which is being drawn in with the intake air by the opening of the intake valve opened and closed in the small lift amount, and to enhance the combustibility in the combustion chamber.

Internal combustion engine

An internal combustion engine having an assist air supply device for finely dividing injected fuel and an exhaust gas recirculation device for selectively circulating an exhaust gas from an exhaust passage into an air intake passage. In this internal combustion engine, a swirl operation for a lean burn during a low load on the engine and a non-swirl operation for a burn based on a theoretical air-fuel ratio can be selectively switched between such operations. In the non-swirl operation, the supply of an assist air and the recirculation of a large amount of an exhaust gas are carried out. This makes it possible to reduce both specific consumption of fuel and the amount of NO.sub.x in the exhaust gas over the entire operational region of the engine.

A fuel injection type internal combustion engine has a pair of intake ports provided in a cylinder head to connect a pair of intake valve bores facing a combustion chamber with a single intake inlet end. A fuel injection valve is disposed in an orientation frm the intake inlet end toward both the intake valve bores and includes an assist-air supply means for finely atomizing the fuel. A valve operating mechanism is provided for selectively stopping the intake through one of the intake ports in accordance with the operational condition of the engine. A control means is connected to the assist-air supply means for controlling the assist-air supply means to stop the supply of assist air from the assist-air supply means in at least a portion of an operational region in which the intake through one of the intake ports is substantially stopped. This ensures that the impediment of the production of the swirl by the assist air can be avoided by stopping the supply of assist air in a condition in which the intake through one of the intake ports is substantially stopped to produce a swirl in the combustion chamber.
