A "smell" is added to propane the same as a "smell" is added to natural gas. Some people describe it as being like old cabbage. I can attest that it is not pleasant and unless you have very poor sense of smell you will notice it. Don't ignore it if you do. Propane is heavier than air and will lie in a low area and is very combustible.
sounds like an exhaust leak, or a fuel leak. that depends on the smell.
I dont know why it might smell like propane in your case but my car runs on propane so the exhaust has a propane sorta smell to it. In your case id check your exhaust. You might need a new catalytic converter or something may be leaking under your hood.
Yes, a catalytic converter can influence the smell of exhaust fumes. If the converter is functioning properly, it helps reduce harmful emissions and can eliminate some of the rich, fuel-like odors. However, if the catalytic converter is failing or there's an issue with the engine, such as incomplete combustion or fuel mixture problems, it may lead to a richer smell in the exhaust fumes. In such cases, addressing the underlying issues can help mitigate the odor.
If your car heater smells like exhaust fumes, it could indicate a leak in the exhaust system, allowing harmful gases to enter the cabin. Another possibility is that the heater core is leaking coolant, which can produce a similar odor. It's essential to address this issue promptly, as inhaling exhaust fumes can be hazardous to your health. Consider having a mechanic inspect your vehicle to identify and resolve the problem.
Could be a leak in the manifold, or a hole in the exhaust, and when you stop the car there is no pressure blowing off the fumes, so it floats up into the car.
The smell of propane while driving up a hill in a 1998 Jeep Wrangler could indicate a leak in the fuel system or exhaust system. It is important to have the vehicle inspected by a mechanic to identify and fix the source of the propane smell to prevent any safety hazards.
No they don't smell like anything
may be pre-cat exhaust leak.
A car might smell like propane while driving due to a leak in the fuel system, particularly if it's a vehicle that runs on propane or has components that use it. Alternatively, if the car is running on gasoline, a strong odor could indicate a fuel leak or an issue with the exhaust system. It's important to address this smell promptly, as it can pose safety hazards, including fire risks. If this occurs, it's advisable to have the vehicle inspected by a professional mechanic immediately.
There is no smell, unless somebody has used something like 22a freon which is actually propane and may have a sulphur smell
Well if you have a hole in your exhaust like rite under your car, it is able for the exhaust fumes to get into your car and kill you ;P
