The two primary emissions produced by internal combustion engines are carbon dioxide (CO2) and nitrogen oxides (NOx). CO2 is a greenhouse gas resulting from the complete combustion of fossil fuels, while NOx is formed at high temperatures during combustion and contributes to air pollution and smog. Both emissions significantly impact climate change and air quality.

How many oxygen sensors are on a jeep 4.0 engine?
Most 4.0L engines with federal emissions have two oxygen sensors located on the exhaust pipe before the muffler. One sensor is mounted before the catalyst (upstream) and one is mounted after the catalyst (downstream). Most 4.0L engines with California emissions have four oxygen sensors. These are mounted in the exhaust manifold area. Two are upstream and two are downstream. There is an emissions label under the hood of the vehicle that identifies the emissions type.
What are the emissions from jet planes?
Water vapor and carbon dioxide are the two main outputs from a jet engine.
Why does the check engine light stay on on a 1999 subaerban when nothing is wrong with it?
the check engine light means you have something wrong with your emissions. it might be the two sensers on the exhaust pipe.
On a 1998 intrigue why are there two check engine lights?
The 'Service Engine Soon' light is required by the OBD-II standard for vehicle systems. It is required to light when a malfunction occurs that will increase the emissions level of your vehicle. The 'Service Vehicle Soon' light is simply a safety item to tell you something is wrong, even if it's not engine or emissions related.
Working of twins spark plug in two wheeler?
2 spark plugs in the same cylinder improve combustion, reduce emissions and operating reliability of the engine.
How many catalytic converters are on a 2004 Jeep Liberty with a 3.7 engine?
The 2004 Jeep Liberty with a 3.7L engine has two catalytic converters. This is because the engine has two separate exhaust manifolds, each of which is connected to a separate catalytic converter. The two catalytic converters help to reduce the emissions produced by the engine, and they are located underneath the vehicle, near the exhaust system.
Why two stroke engine ban in Pakistan?
Because 2 stroke engines consume oil in their operation. This produces high levels of emissions and is unhealthy for people and the enviornment. $ stroke engines do not mix oild and fuel so their emissions are much lower.
Why are there four spark plugs in Yamaha v star 1100 when there are only two cylinders in the engine?
For a more efficient combustion of fuels also helps cut harmful emissions.
Why does two stroke engine pollute air more than a four stroke engine?
Two-stroke engines generally pollute the air more than four-stroke engines due to their design and operation. In a two-stroke engine, the combustion cycle is completed in just two strokes of the piston, which often leads to incomplete combustion and unburned fuel escaping during the exhaust phase. Additionally, two-stroke engines typically mix oil with fuel for lubrication, resulting in higher emissions of hydrocarbons and particulate matter. In contrast, four-stroke engines have a more efficient combustion process and separate lubrication systems, leading to lower emissions.
How many catalytic converters does a 1997 Kia Sephia have with a 1.8 dohc engine?
if its CA emissions, it will deifnately have two one bolted to the exhaust manifold and one not too far behind that one
What benefits do hybrid cars offer?
Hybrid cars reduce harmful emissions that regular cars emit into the air. They also contain two engines, an electric engine and a gas engine, so that if one breaks, the other will keep you going until you can repair it.
Why do most very small engines operate on 2 stroke?
Most small engines are two stroke because you can get more power from a smaller engine with two stroke rather than a four stroke engine. It takes less to cool and to operate the engine.
