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.

An engine cooling system comprises a coolant inlet formed at one side of a cylinder block for allowing a coolant to separately flow into the cylinder block and a cylinder head, and a coolant outlet formed at the other side of the cylinder head for allowing the coolant having flowed into the cylinder block and the cylinder head to separately flow out of the cylinder block and the cylinder head. The coolant outlet is formed diagonally opposite to the coolant inlet. The coolant delivered from a water pump separately flows into the cylinder block and cylinder head, whereby a cooling efficiency of the engine is improved.

An engine ladder frame with minimized noise and vibrations, improved stability of the oil filter, and reduced air in the oil flowing from the cylinder head to the oil pan. Inside an elongate rectangular outer block, three partitioning walls are formed equidistantly, so as to form four crank chambers. The crank chambers respectively have bottom faces which are not perforated or open but are completely closed. On the side parts of the bottom faces, there are respectively formed oil flow faces which gradually become deeper in the direction of the revolutions of the crankshaft. Among the oil flow faces, those of the first, second and third crank chambers have oil drain holes respectively at their ends. Thus the bottoms of the crank chambers are closed so as to close the space between the cylinder block and the oil pan, resulting in the reduction of the noise and vibrations.
