Various systems are provided for a charge-air cooler system. In one example, a system includes a turbocharger system having at least one compressor and one turbine and configured to provide charge air to an engine. The system also includes a charge-air cooler system having at least one charge-air cooler arranged below the at least one compressor, a turbocharger bracket arranged directly below the charge-air cooler system and shaped to mount the charge-air cooler and the turbocharger system to the engine, and a stator adapter physically coupling an alternator to the engine. The stator adapter includes an accessibility window arranged below the charge-air cooler system. The at least one charge-air cooler is closer to the accessibility window than the turbocharger system.

An engine including a main fuel injection valve, a pilot fuel injection valve, a liquid fuel supply rail pipe, and a pilot fuel supply rail pipe. The main fuel injection valve supplies liquid fuel from the liquid fuel supply rail pipe to a combustion chamber during combustion in a diffusion combustion system. The pilot fuel injection valve supplies pilot fuel from the pilot fuel supply rail pipe to the combustion chamber in order to ignite gaseous fuel during combustion in a premixed combustion system. The liquid fuel supply rail pipe is disposed at one side of an imaginary vertical plane including an axis of a crank shaft. The pilot fuel supply rail pipe is disposed at the side of the imaginary vertical plane at which the liquid fuel supply rail pipe is disposed.

An engine device including a cylinder block having one side portion to which a flywheel that is rotated integrally with a crankshaft is disposed. The engine device is provided with a starter that transmits a rotational force to the flywheel at a time of engine start. A flywheel housing, which accommodates the flywheel and includes a starter attachment pedestal for attaching the starter, is attached to the one side portion of the cylinder block. The starter is disposed inner side of the engine than a portion of the flywheel housing, the portion being located outermost in the engine with respect to a direction that is perpendicular to a direction along a crankshaft center and that is parallel to the cylinder head joining surface of the cylinder block.

An engine includes: an exhaust manifold 7 close to one of left and right side surfaces of an engine; a turbocharger 60 having an exhaust-side inlet connected to the exhaust manifold 7; and a rocker-arm-chamber-integrated intake manifold 8 being disposed on an upper surface of a cylinder head 5 and integrally including a rocker arm chamber 90 and an intake manifold 6. The intake manifold 8 has a wall 101 dividing the rocker arm chamber 90 close to the one of the left and right side surfaces of the engine 1 and the intake manifold 6 close to the other of the left and right side surfaces to isolate the rocker arm chamber 90 and the intake manifold 6 from each other. The rocker arm chamber 90 has, in its upper portion, a positive crankcase ventilation device 69 protruding therefrom and being configured to return blowby gas to an intake system. The positive crankcase ventilation device 69 has, in its side surface, a blowby-gas discharge port 67 connected with a gas conduit 68 through which blowby gas is delivered to an intake-side inlet of the turbocharger 60.
