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.

A cylinder block is provided. The cylinder block includes a cylinder, two crankshaft supports at a bottom of the cylinder block, a cylinder head engaging surface at a top of the cylinder block, and first and second exterior sidewalls, the first exterior sidewall extending from the cylinder head engaging surface to a first structural frame engaging surface positioned above a centerline of the two crankshaft supports.

A heat exchanger for cooling a liquid has an inlet and an outlet for a liquid to be cooled. A bypass is provided that bypasses the heat exchanger. A valve controls flow of liquid into the heat exchanger or into the bypass. The valve has a valve seat, a valve cone, and at least one spring made of a shape memory material. The at least one spring counteracts a liquid pressure existing in the inlet.

A method of modifying the oil cooling system of a diesel engine includes the steps of removing the original equipment liquid-to-liquid heat exchanger and installing a manifold having a configuration adapted to match the mounting configuration of the oil passages of the original equipment liquid-to-liquid heat exchanger. The manifold has an oil outlet port directed to a remotely mounted oil cooler. The manifold also has a water passage having a configuration that is adapted to match the mounting configuration of the water passages of the original equipment liquid-to-liquid heat exchanger. The water passage causes the entirety of the flow of water to be discharged back to the water cooling system of the engine where it is circulated by the water pump through the water cooling passages in the engine.

There is provided an engine. An exhaust manifold is attached to an exhaust port of a cylinder head. A supercharger has a turbine housing accommodating therein a turbine configured to rotate by an exhaust air from the exhaust port. A balancer is disposed at a front side in a crank case. A radiator is disposed in front of the engine. The exhaust manifold and the turbine housing are integrally formed. The supercharger is disposed above the balancer. The radiator is disposed above the supercharger.

A structural frame is provided. The structural frame includes a bottom surface, first and second cylinder block sidewall engaging surfaces, the first and second cylinder block sidewall engaging surfaces positioned above the bottom surface at a height that is above a centerline of a crankshaft support included in a cylinder block when the structural frame is coupled to the cylinder block.

A heat transfer apparatus for cooling and/or heating engine lubricant, fuel, and engine oil is provided which includes a heat-transferring jacket. The heat transferring jacket includes a body having a plurality of fins. The body further includes an air-intake inlet, a plurality of air-exhaust outlets formed along the first lateral terminus and the second lateral terminus, and a means for securing the body to an oil filter.

A system for circulating oil coolant and exhaust gas in an engine including an oil transfer tube, an oil filter cap, a bypass manifold, a coolant manifold, an adapter plate, a coolant filter hosing, a high pressure filter screen, a pump, and an EGR delete. The oil cap and the oil transfer tube act in conjunction to redirect the oil flow. The bypass manifold is able to replace an oil heat exchanger in the oil reservoir of an engine. The coolant manifold is able to redirect coolant. The adapter plate is able to be attached to an OEM oil heat exchanger. A coolant filter is able to filter coolant in the system. The EGR delete enables a system to bypass the EGR system in a simple convenient way. The high pressure filter screen is able to filter in high pressure environments. The pump can be used to direct coolant to the coolant manifold. These elements can be provided in a kit that is designed for certain makes of vehicles. A means to manufacture a bypass manifold is also provided.

The oil side-flow cleaning device includes a heating unit (11) installed between the oil tank and the filter unit (10) so that, when the oil temperature is below a defined limit value, oil flows through the filter unit (10) in such a way as to bypass the filtering function and is heated; and so that, when the oil temperature is above the defined limit, oil flows through the filter unit (10) so as to be subjected to the oil filtering function. In addition or as an alternative, the oil side-flow cleaning device comprises a backflush unit including a backflush collecting tank (17) and a backflush nozzle (18), wherein, when the device is in backflush mode, oil flows through the filter medium (16) in a second, opposite direction as a function of the position of the backflush nozzle (18) relative to the filter medium (16).

Disclosed is an oil filter base assembly, including an oil filter base, where the oil filter base has one side connected to a first cooler arranged and the other side connected to a second cooler arranged; With the arrangement of the first cooler and the second cooler on the oil filter base, a medium may pass through the two coolers and be cooled simultaneously by the two coolers, thereby improving the cooling effect of the oil filter base assembly. Therefore, the present invention is worthy of popularization and application.
