Rear   Engine   -Mounting Flywheel The engines can be fitted with different flywheels for connection to a torque converter and transmission or a fixed or flexible coupling. Refer to Sales Support Tool, Partner Network. The flywheel stores energy created during the power stroke and releases it during the rest of the cycle, which reduces speed variations in the crankshaft and timing during the cycle. It is especially important that the flywheel has sufficient inertia to provide good starting characteristics at low temperatures. Inertia A given minimum rotation inertia is necessary to maintain a sufficiently high piston speed during the compression stroke in order to provide enough compression heat for the injected fuel to ignite. Even if the average initial cranking speed is the same on flywheels with different inertias, the cyclical speed variation can vary significantly (see illustration). Low inertia flywheels are preferable in vehicular applications whe...

Synthetic Engine Oils  of Volvo Engine General Synthetic engine oils have very good flow characteristics in cold conditions. The characteristics of many chemical products have been studied in regard to the manufacture of synthetic oils in order to determine their suitability as lubricants. The most common chemical products are hydrocarbons, esters, polyglycols, phosphate esters and silicon etc. The oil companies have since chosen a suitable basic product for further development, e.g. poly- α -olefins, diesters and polyol esters A study of different synthetic fluid characteristics in comparison to paraffin-based mineral oils shows that no product has excellent characteristics across the whole spectrum. The most common areas of use for the above-mentioned synthetic oils are: Poly-alpha-olefins: Engine oils, gear lubricants, turbine and compressor lubricants, grease and hydraulic fluids. Organic esters: Same as above and also gas turbine oils. Polyglyco...
