Sažetak
The powertrain is the “heart” of a vehicle. It is the singular most expensive and most complex part of every vehicle. The powertrain consists of the engine, intake, and exhaust subsystems, and the transmission and drivetrain systems. The powertrain is one of the major sources of vehicle sounds and vibrations. In general, powertrain vibration and sound sources consist of the following: 1. Engine, including combustion-related sounds and vibrations, reciprocating unbalance, rotating unbalance, crankshaft torsional oscillations, etc; 2. Valve Train system, including valves, cam system, timing belt, or chain; 3. Accessories, including their unbalance and resonance; 4. Intake system and exhaust system vibrations; 5. Driveshaft first-order resonance; 6. Universal joint second-order bending vibrations and torsional vibrations; and 7. Axle vibrations due to gear tooth conjugation error, transmission error, pinion par eccentricity, slip-stick between pinion and ring gear, etc.In this work various sources of noise in an engine have been analyzed.
