The present disclosure relates to a 2-cycle engine with a valve system that generates power during every one crankshaft rotation. The 2-cycle engine of the present disclosure includes the valve system opening and closing an air intake valve and an exhaust valve and includes a turbocharger. In the turbocharger, the air intake valve and the exhaust valve are respectively opened and closed once during one crankshaft rotation, and the valve system is configured to control the turbocharger using difference between an air intake pressure and an exhaust pressure. Accordingly, a current air intake reaches a target air intake.

The present invention provides a protective glove which improves protection and wearability by integrating protective members using features of thermosetting material and thermoplastic material. The protective glove comprises: a bodyinto which a back of hand, a palm and fingers of a wearer are inserted; a first protective membermade from thermosetting material, which is formed to protect a predetermined portion of the wearer's hand and exposed to outside and which is integrally attached to an outer surface of the body; and a second protective membermade from thermoplastic material, which is formed to protect a predetermined portion of the wearer's hand and is integrated with the first protective member, and which is attached to the outer surface of the body

Protective glove and method of manufacturing the same

A glove includes spaces formed at parts corresponding to the knuckle part of the hand and joint parts of the fingers to guarantee the movement and protection of the knuckle part and the joint parts. The glove also includes protection members longitudinally formed in a shape corresponding to each finger, thereby effectively protecting all the fingers. The protection members are formed from a lightweight, soft material, thereby reducing the fatigue of a wearer due to wear sensation. A cover member is formed from a rigid material to protect the hand and each of the protection members from the outside.

A variable intake system includes a pair of surge tanks connected in a communicating manner to a main intake pipe through a low speed communication pipe and a high speed communication pipe, a middle speed communication pipe for connecting the pair of surge tanks, and a noise reducing member integrally provided at the middle speed communication pipe to reduce noise.

Variable intake system

A vehicular exhaust device is disclosed. The vehicular exhaust device includes an exhaust pipe, which is connected at one end to an exhaust manifold of a cylinder and at the other end to a catalytic converter. In particular, an intermediate portion of the exhaust pipe is in contact with the side surface of the catalytic converter so as to heat the catalytic converter by heat of the exhaust pipe.

Vehicular exhaust device

Output performance of the engine may be maximized by a configuration in which air is supplied so as to maximize volumetric efficiency of the respective cylinders in a multi-cylinder engine including a plurality of cylinders.

Intake system for engine

A catalyst can of exhaust gas can include a catalyst embedded substantially in the center of an inner space of the catalyst can, and an inflow space and a discharge space partitioned in an upper part and a lower part of the catalyst can, respectively. The catalyst can also includes an inflow-side partition vertically cutting and dividing the inflow space into a plurality of partial inflow spaces, and an inlet formed for each partial inflow space.

Apparatus and catalyst can for exhaust gas of vehicle

The present invention provides to a rocker arm apparatus for cylinder deactivation with a new structure for increasing fuel efficiency in a gasoline engine. For this, the present invention provides a rocker arm apparatus for cylinder deactivation including: a rocker arm; a restoring spring supported at the bottom of a rear end portion of the rocker arm; a roller coupled to the rocker arm to be pressed by a cam; a pair of rocker shaft assemblies each including first and second rocker shafts, and a connecting rod integrally connecting the first and second rocker shafts; a pair of rocker shaft support members connected to the rocker arm by means of the first and second rocker shafts; and a transfer member for controlling the rocker shaft assembly.

Rocker arm apparatus for engine cylinder deactivation

An electro-hydraulic variable valve lift apparatus may include a valve unit housing of which a guide protrude portion is formed therein, a main piston which is slidably disposed in the valve unit housing and defines a valve adjusting oil chamber with the valve unit housing, a main spring which is disposed within the valve adjusting oil chamber and elastically supports the main piston on the guide protrude portion, a dependent piston which is slidably disposed within the valve unit housing, is guided along the guide protrude portion, reciprocates according to reciprocation of the main piston, and opens a valve, and a main oil supply portion which selectively supplies hydraulic pressure to the valve adjusting oil chamber.

Electro-hydraulic variable valve lift apparatus

An exhaust gas recirculation system of an internal combustion engine where a cylinder head having an intake port and an exhaust port is coupled to a cylinder block, and a portion of an exhaust gas exhausted from the exhaust port is flowed into the intake port through a control valve, may include a recirculation gas gallery integrally formed at the cylinder head and communicated with the intake port, a control valve assembly including the control valve and communicated with the recirculation gas gallery, and at least a recirculation gas extracting unit that is communicated with the control valve assembly and the exhaust port.

Exhaust gas recirculation system with unified cylinder head and exhaust gas recirculation device

A variable compression ratio apparatus for varying a compression ratio, may include a connecting rod that is connected to a piston to take a combustion force; a pin link, one end of which is eccentrically connected to a crankshaft and the other end of which is pivotally connected to the connecting rod to form a connection portion therebetween; a slot link including a control slot to receive and guide the connection portion along the control slot; and a driving unit coupled to the slot link and configured to move the control slot to control a position of the connection portion.

Variable compression ratio apparatus

A variable valve lift apparatus includes a camshaft with a first cam lobe and a second cam lobe, a cam follower with a first follower contacting the first cam lobe and a second follower contacting the second cam lobe, a connection rotatably connecting the first follower to the second follower, a main body supporting the first follower and the second follower, a connector selectively connecting the first follower and the second follower to the main body, a lost motion elastic member provided on the main body for supplying restoring force to the first follower and the second follower, and a valve configured to be opened and closed by the cam follower.

Variable valve lift apparatus

The present invention relates to an intake manifold for a vehicle and comprises tanks for stabilizing intaken air introduced from a throttle body; a plurality of zip tubes diverged from the tanks; a plurality of runners connected to the zip tubes and communicated with respective cylinders; and a adjustment apparatus provided at one side of the zip tubes and the runners for varying the diameter of the zip tube and the diameter of the runner according to an engine operation range. Due to the above structure, the diameter of the zip tube and the diameter of the runner can be varied continuously within the overall operating range of an engine by the adjustment apparatus. Hence, the performance of the engine can be enhanced.
