An exhaust gasket such as the Hyundai exhaust gasket is an essential component of an automobile engine. An exhaust gasket is a precisely machined sheet of metal that fits perfectly between the exhaust manifold and the engine block's exhaust valve train. Its main purpose is to seal the exhaust manifold to the engine block. It prevents exhaust gases from directly escaping the engine block. It allows the exhaust manifold to collect the exhaust gases and channel these exhaust gases through the exhaust pipes. Na exhaust manifold resemble a collection of pipes fused together. Each exhaust valve has specific exhaust manifold opening. Exhaust gases are collected by each exhaust manifold opening from a single exhaust valve. Then, the exhaust gases are pooled together in the collector of the exhaust manifold.

This is done to minimize the backflow of exhaust gases. If the exhaust gases are collected through a single opening, pressure will not be preserved, creating a backflow. The exhaust manifold gasket helps in preventing backflow by preserving the pressure inside the exhaust manifold. The backflow of exhaust gases can create problems in the combustion process. Since exhaust gases are mostly waste products that are inert, backflow will reduce the concentration of oxygen and fuel in the combustion chambers. Consequently, the efficiency of combustion will be reduced. Engine output will drastically decline and pollution output will increase. The engine may eventually breakdown.

On the other hand, if the exhaust gasket is busted, exhaust gases will escape directly from the engine block. The hood of the automobile would be a smoking contraption. This is not only aesthetically unappealing but also dangerous. Some of the exhaust gases may enter the HVAC (heating ventilation, and air conditioning) system of the automobile. Even if the leak is small, it could potentially cause suffocation of the passengers inside the vehicle. Carbon dioxide, carbon monoxide and nitrous gases are just some of the by-products of combustion. If these gases are inhaled, the victim may suffer respiratory spasm, dizziness, drowsiness and nausea. Carbon monoxide is particularly dangerous because it is an oxygen antagonist.

Carbon monoxide is odorless and colorless, making it almost impossible to detect without special instruments. Carbon monoxide is fatal because it competes with oxygen. It replaces oxygen in the blood, making the blood more acidic and unable to supply oxygen to the cells of the body. The brain is particularly susceptible to carbon monoxide poisoning. The symptoms of carbon monoxide poisoning are subtle. The victim may first feel drowsy and eventually will fall asleep. This could lead to coma or death. Hence, the exhaust gasket plays a vital role in the safety of the passengers. Parts Train offer durable aftermarket exhaust gaskets at very affordable price.
