A hybrid system for a vehicle having an engine and a driving motor includes a plurality of engine power generation modules for generating power with an operation of the engine, a battery for storing power output from the engine power generation modules, a plurality of driving modules for driving the driving motor for driving wheels of the vehicle by the power output from the engine power generation modules or the battery, and a control unit for selectively controlling operations of the engine power generation modules and the driving modules to match a required output of the vehicle.

Hybrid system for vehicle provided with plurality of engine power generation modules

A spark plug for increasing a combustion speed of a gasoline engine may include electrodes of a spark plug, which ignite a mixture of fuel and air in a combustion chamber of an internal combustion engine, wherein the electrodes of a spark plug are positioned at a position where a flow velocity is high, and one end portion of a body of the spark plug and an end portion of a cylinder head on which the spark plug is disposed are positioned on a diagonal line to induce a tumble flow downward and allow a flame generated at the spark plug to expand toward a center portion of the combustion chamber where turbulent flow energy is high, such that both an initial combustion speed and a main combustion speed are high.

Spark plug for increasing combustion speed of gasoline engine

An engine cylinder head cover and assembly method thereof is disclosed to constantly maintain the arrangement of a cylinder head cover in relation to a cylinder head by a simple operation, whereby locking bolts for fastening the cylinder head cover onto the cylinder head can be quickly and effectively assembled, thereby improving ease of assembly of the engine.

Engine cylinder head cover and assembly method thereof

A timing chain cover of an engine, where the engine adjusts the tension of the timing chain by using a tensioner formed with a ratchet bar, comprises a tool insertion hole, where a tool is inserted to loosen the timing chain, thereby separating the camshaft away from the engine without detaching the timing chain cover, obtaining an easy maintenance for the engine.

Timing chain cover of engine

An oil separating apparatus for blow-by gas adapted to form a funnel shaped space in a cylinder head cover to prompt oil contained in the gas to be introduced to an oil line along an inner circumference of the space by way of centrifugal force, thereby inducing the blow-by gas, free of oil, towards a positive crankcase ventilation (PCV) valve.

Oil separating apparatus for blow-by gas

An engine chain cover wherein a passage for passing the blow-by gas is formed at one side of the chain cover to shorten the manufacturing process of a cylinder head and save manufacturing costs, and some of the oil is separated from the blow-by gas when the blow-by gas passes through the passage of the chain cover to thereby improve the separation efficiency of the oil.
