Abstract:
An engine system of a dual injector includes a first injector directly injecting a first fuel into a combustion chamber. A second injector directly injects a second fuel into the combustion chamber. A first fuel tank is connected to the first injector and stores the first fuel therein. A second fuel tank is connected to the second injector and stores the second fuel therein. The first fuel is in a liquid state and the second fuel is in a gas state at room temperature of atmospheric pressure.
Abstract:
A cooling system of an engine may include a cylinder liner formed in a hollow cylindrical shape and pressed against an inside of a cylinder of the engine, a block coolant jacket positioned in an outer side of the cylinder liner in a radial direction to cool a cylinder block, the cylinder block provided with the cylinder liner and the block coolant jacket therein, and a cylinder head engaged on the cylinder block, including an exhaust port and an intake port fluidically-communicated with a combustion chamber and respectively formed at an exhaust side and an intake side, and provided with a head coolant jacket inside, in which the block coolant jacket includes an upper coolant jacket and a lower coolant jacket and a division wall is disposed between the upper coolant jacket and the lower coolant jacket to block fluid flow therebetween.
