An exhaust manifold and diffuser integrated cylinder head, includes an exhaust manifold and a exhaust passage. The exhaust manifold is integrally formed with the cylinder head. The exhaust passage is integrally formed with the cylinder head such that a turbocharger is mounted on a joining part of exhaust ports of the exhaust manifold and exhaust gas discharged from the exhaust passage flows to the turbocharger.

Exhaust manifold and diffuser integrated cylinder head

An exhaust port structure of a cylinder head includes a connection pipe communicating with a plurality of exhaust ports of the cylinder head and an exhaust hole connected to the connection pipe and performing a function of an exhaust manifold, wherein the connection pipe has an EGR line integrally formed and connected thereto and each of the exhaust ports is formed with the same shape or a symmetrical shape, and the present invention can reduce the weight of the cylinder head and the manufacturing cost and improve the EGR rate and T/C efficiency.

An electric water pump control apparatus actively controls an electric water pump in a high speed range or a high load condition as a vehicle accelerates or overtakes. An electric water pump control method may include determining whether an engine is in a high speed/high load condition or in a normal condition by detecting an engine speed, fuel consumption amount, and coolant temperature, determining whether the coolant temperature is less than a predetermined second temperature, if the engine is in a high speed/high load condition, calculating a speed of the electric water pump by applying fuel consumption amount and engine speed, if the coolant temperature is less than a second temperature and determining a final speed of the electric water pump by applying a compensation coefficient according to the coolant temperature, and operating the electric water pump with the final speed to circulate the coolant.
