As well as causing overheating, excessive unburnt fuel can contaminate the catalytic converter, making it fail. Leaking oil and coolant have the same effect. Several things, such as a clogged oxygen sensor, can cause unburnt fuel to enter the exhaust system. When this happens, your engine ...
The last type is the Three-Way Catalytic Converter. The Three-way catalyst helps convert the harmful gases exhausted from the engine into harmless gases. The engine exhaust gases contain hazardous substances that cause damage to the environment. These include the oxides of nitrogen, hydrocarbons, an...
Inside the catalytic converter are ceramic blocks, made up of thousands of micro-ducts like a honeycomb. This provides a high surface area for gases to pass over. But it’s the palladium-rhodium catalyst coated on the surface of the honeycomb that does the real work, undertaking the three ...
A catalytic converter is a portion of your exhaust system designed to reduce emissions. It looks like a small muffler on the outside, but the inside structure is what makes it unique. There, you’ll find a honeycomb mesh coated in precious metal designed to maximize the surface area so tha...
then a muffler, and finally out into the atmosphere. An oxygen sensor before the catalytic converter and one after it read the composition of the exhaust gases. These readings then tell the ECU if the fuel mixture is adjusted correctly as well as if the catalytic converter is functioning corre...
This type uses a crankshaft position sensor for ignition timing, providing more precise control than a mechanical distributor. This setup improves reliability and performance. Wasted spark coil pack. Source: ngk.com Coil-on-Plug (COP) The coil-on-plug system places an individual ignition coil...
Analysis of the Impact of the New Emissions Limits on the Temperatures of the Vehicle Floor In order to meet the requirements of the new emissions limits, the volume of the catalytic converter is higher, increasing the heat rejected. It provokes... GI Bicalho,BDS Baptista,FVLD Silva,... -...
The engine sensor control system contains many types of sensors, such as temperature sensors, pressure sensors, position and speed sensors, oxygen sen...
