Sharp exhaust smell

When I started the car, I noticed a sharp smell. It wasn't normally. After running the car, I noticed when I got off to get something from the dam. Pretty sharp. No smoke. There is no problem. I changed the place where I took the fuel, could it be fuel? I used to get it from the PO, I always get it from the shell when it closes, but it is always a quarter warehouse.

Yes, my teacher can make use of fuel, but it can be generally related to the floor.

Of course, fuel-related issues come from injectors, or catalysts, if the vehicle is diesel.

Diesel yes. I think we need to change and check the fuel again.

Well, as you said, if the injector and catalyst problem, what should be done? Is it an urgent problem to be solved? Oktk is 2017-01-24 11:58:52

I have been in the last 3 or 4 days,

Yes, when the engine gets hot.

I have been smelling this smell for 3 years .. it smells very bad at the first starts .. it decreases when the engine gets hot. I thought it was normal.

I think either the smell decreases when the EGR is opened or I did not know when the catalyst warmed up.

Isn't it normal now?

this smell becomes more in winter :)

Yeah.

My master says it will be injectors, he said maintenance should be done ...

There is obvious increase in fuel, as if there is a decrease in traction. I think the injectors should go to maintenance. It would be better not to waste time in this injector event, it would cause trouble both in fuel consumption and damage to the pistons! Let's see how much maintenance costs will incur!
