Service Catalytic converter Catalytic Converter: - The catalytic converter converts harmful pollutants in the exhaust gas into harmless gases. It is located in the exhaust system and all exhaust must flow through it.The catalyst is a material in the catalytic converter that causes a chemical change without being a part of the chemical reaction. A catalytic converter may have two different catalysts. One treats the HC and CO.

Test Spark timing control system In a gasoline engine, the air fuel mixture is ignited to cause combustion, and the force that is generated by the expansion causes the position of piston to push downwards.Therefore, Ignition takes place in advance so that enable the engine to generate the maximum combustion every moment depending on the operating conditions of the engine. SO, The timing that enables engine to generate an explosive force in the force in the most efficient manner in accordance with the operating condition.

Service Positive Crankcase ventilation system Filtered Air from the air cleaner is drawn through the crankcase by the intake manifold vacuum. The air picks up the blow-by gas or vapor and carries them to the intake manifold. The vapors then flow through the intake manifold to the combustion chambers. There the unburned fuel burns during normal combustion.
