(1) Crankcase upper section
(2) Crankcase lower section The cylinder block is the main housing of the engine and supports the other main parts. The cylinder blocks utilize a ladder frame structure type crankcase design. The cylinder block is made of cast iron and includes complete passages for coolant and lubricating oil.The ladder frame structure design includes the following benefits:
Minimizing Parts
Noise reduction
Reduction of loss and dispersion on friction through accuracy of axial concentricityThis engine does not utilize cylinder liners. The following benefits include improved cooling operation, less strain on components and improved abrasion resistance
Illustration 2 g03002661The cylinder block has a hollow core already cast inside the cylinder to cylinder water jacket.This engine utilizes coolant evenness distribution type cooling jacket inside the top section of the crankcase.Half-Floating Valve Cover

(5) Rubber packing The rubber packing is attached to keep the cylinder head cover approximately 0.5 mm (0.02 inch) off the cylinder head. The rubber packing decreases the noise from the cylinder head.Closed Crankcase Breather

(3) Hose
(4) Hose The close breather system is utilized in order to prevent the release of blow-by gas into the atmosphere.Exhaust gas from the valve cover enters the canister through hose (1). The filter that is contained inside canister (2) removes oil mist and small oil particles from the blow-by gases. The filtered air is returned to the intake through hose (3). Separated oil is returned to the crankcase through hose (4).Combustion Chamber

(12) Combustion chamber
(13) Piston Fuel is injected directly at the center of the cylinder. This allows uniform mixture of injected fuel and inlet air, which leads to more stable, higher combustion performance. The benefits include: cleaner emissions, higher power output, lower fuel consumption, lower operating noise and higher start-up performanceCrankshaft
Illustration 6 g02792771The crankshaft converts the up-and-down motion of the pistons into rotary motion. The crankshaft ties together the reactions of all the pistons into one rotary force that drives the machine.The crankshaft is made of tough special alloy steel, and the journals, pins, and oil seal sliding portions are induction hardened to increase the hardness for higher wear resistance.The front journal is supported by a solid type bearing (tunnel type cylinder block) or by a split type (hanger type cylinder block), and the intermediate journal by a split type, and the rear journal by a split type with thrust bearings.The crankshaft is provided with an oil gallery, through which engine oil is fed to the crankpin portion, and lubricates.Camshaft
Illustration 7 g03007258
(14) Camshaft gear
(15) Camshaft The camshaft is normally driven by gearing from the crankshaft.The camshaft is made of special cast iron, and the journal and cam sections are chilled to resist wear. One intake and one exhaust cam is provided for each cylinder.The journal diameters are large in order to permit removal of the shaft from the bore. The journal sections are force-lubricated.Note: There are no camshaft bearings for these engines.Gear Train

(18) Camshaft gear
(19) Crankshaft gear The gear train is located on the flywheel side of the engine.The crankshaft is the hub around which other parts of the engine can be timed and driven. This is done by the meshing of gears as shown in the Illustration 8.The timing gears transmit torque from the crankshaft to the oil pump and injection pump and, at the same time, correctly control fuel injection to the cylinders and valve timing.Each gear has an inscribed mating mark for correct and easy assembly and is spherical with teeth set obliquely to the axis of rotation to rotate smoothly and reduce noise.Flywheel
