Other examples of transverse waves include light waves and water waves. Both types of seismic wave can be detected near the earthquake centre but only P-waves can be detected on the other side of the Earth. This is because P-waves can travel through solids and liquids whereas S-waves can only travel through solids. This means the liquid part of the core blocks the passage of S-waves.
Have your vehicle's exhaust system inspected periodically to keep your car safe. Loose, missing or damaged hangers or brackets can allow the exhaust system to shift around, causing a possible clunking or rubbing sound while driving. A loose exhaust system, when hot, can also melt wiring, nylon lines or rubber hoses.
Incomplete combustion occurs and soot is formed when there is an overabundance of fuel (both diesel fuel and lube oil), insufficient residence time in the combustion zone, and/or non-availability of sufficient oxidants. Over-fueling is the primary cause of black smoke from the exhaust of a heavy duty diesel engine.Over-fueling can be caused by diesel fuel injector wear that enlarges the nozzle hole or erodes the injector needle and allows excess fuel to flow into the combustion chamber.ncomplete combustion occurs and soot is formed when there is an overabundance of fuel (both diesel fuel and lube oil), insufficient residence time in the combustion zone, and/or non-availability of sufficient oxidants.
