The Key Elements of Great Automobiles
A secondary air injection is a strategy that is used in motor vehicles emission systems in order to control the emissions. It has been around fifty years since the secondary air injection system was introduced. This efficient system works by injecting fresh air into the waste gas stream so as to enhance that exhaust gases are completely combusted.
The principle of operation of the secondary air injection system usually depends on the mode of the injection of the fresh air as well as where it is injected into the mechanism. The advancement of technology has led to the wide variation of the secondary air injection device. There has been a great reduction in the emission of dangerous gases to the atmosphere from cars by the use of the secondary air injection system.
The secondary air injection system is usually one that does not require much maintenance. There are conditions like the use of low quality engine oils, extreme running conditions and the damage of the engine start system that can make the valves faulty. A good operation of the secondary air injection system leads to it being effective and efficient.
So as to understand if the system is malfunctioned, you check the speed of the engine without load and if there is any whistling sound. It is required for the proper ratio of oxygen and fuel on the cold starting of petrol engines. When the amount of fuel is excess in the engine high levels of carbon dioxide are usually emitted. Since the secondary air injection system usually has not achieved the right temperature in cold start, the exhaust gases can escape into the atmosphere. There is need to visit a knowledgeable person to assist you with the faulty secondary air injection system.
Fresh air is usually injected into the release system of the vehicle so as to reduce the harmful emissions. The process usually result in the emission of carbon dioxide and water which have been neutralized. There is also an advantage in the raised heat in the exhaust gases.
There are usually two major components of the secondary air injection system. The purpose of the air pressure device is usually to take in air and inject it into the exhaust air emission manifold. The secondary air valves are usually placed in between the air pressure device and the exhaust gas stream. For the effective and efficient reduction of high concentrations of carbon dioxide and hydrocarbons which are not completely burned, secondary air injection systems are applied. This system has been very helpful in the reduction of the release of unwanted gases in the atmosphere.
