Emissions and Exhaust Systems
Internal combustion engines have byproducts called emissions. These byproducts are either particulates or gaseous chemicals. Emissions travel from the engine via an exhaust system, which is a system of pipes that leads the emission away from the combustion source.

What would cause strong gas smell from exhaust pipe?
A strong gas smell from the exhaust pipe can indicate incomplete combustion, often caused by a malfunctioning fuel injector, a faulty spark plug, or an issue with the air-fuel mixture. Additionally, a clogged catalytic converter can lead to poor exhaust flow and increased emissions, contributing to the odor. Leaks in the fuel system or a damaged exhaust system may also result in noticeable gasoline fumes. It's advisable to have the vehicle inspected to prevent potential safety hazards.
In a 2004 Chevrolet Suburban, the evaporative (EVAP) control system canister vent solenoid circuit malfunction is typically located near the fuel tank. The canister vent solenoid itself is attached to the EVAP canister, which is usually found near the rear of the vehicle, near the fuel filler neck. This solenoid controls the flow of vapors from the EVAP canister to the intake manifold for proper emissions management. If there's a malfunction, it may trigger a check engine light and could affect vehicle performance.
Where is the EGR valve on 2003 CRV?
In the 2003 Honda CR-V, the EGR (Exhaust Gas Recirculation) valve is located on the engine's intake manifold. Specifically, it is often found near the back of the engine, close to the throttle body. To access it, you may need to remove some components, such as the air intake duct or heat shield, depending on your engine configuration. Always consult a repair manual or guide for detailed instructions if you're planning to work on it.
What causes black smoke from the exhaust?
Black smoke from the exhaust typically indicates an excessive amount of fuel being burned in the engine. This can be caused by a variety of issues, such as a malfunctioning fuel injector, a clogged air filter, or a faulty sensor that affects the air-fuel mixture. Additionally, it can occur in diesel engines when there is insufficient air for combustion or if the engine is under heavy load. Proper maintenance and diagnostics are essential to identify and resolve the underlying problem.
How many catalytic convertersare on 2002 montero xls?
The 2002 Mitsubishi Montero XLS typically has one catalytic converter. However, it may have an additional pre-catalytic converter, depending on the specific engine configuration. It’s always best to consult the vehicle's service manual or a professional mechanic for confirmation on the exact setup.
How do you fix a 2007 suburban obdii code for evaporative emissions control vent solenoid?
To fix a 2007 Suburban OBDII code related to the evaporative emissions control vent solenoid, first inspect the solenoid for any visible damage or disconnections. If it's defective, replace it with a new unit. Additionally, check the associated wiring and connectors for corrosion or breaks. After making repairs, clear the code with an OBDII scanner and monitor for any reoccurrence.
Do you need to remove the exhaust pipe to replace the back brake pipes on a fiesta flight?
Yes, to replace the back brake pipes on a Ford Fiesta Flight, it is often necessary to remove the exhaust pipe. This is because the brake pipes run close to the exhaust system, and removing the exhaust can provide better access to the brake lines. Always ensure to follow proper safety procedures and refer to the vehicle's service manual for specific instructions.
