Hello Fellow Tsikot members,

I was just wondering, and hopefully someone can shed some explanation into this, but I noticed that the exhaust smell coming from a hyundai CRDI engine smells different than one that comes from let's say a Toyota (D4D) or Mitsubishi (DI-D) engine.

Yung sa Hyundai kasi (I noticed this with my accent and a Tucson CRDi parked once) parang sour-smelling yung amoy ng exhaust niya. Still smells like diesel exhaust, pero mas maasim and mas masakit sa ilong. Whereas with my architect's Montero DI-D and our company shuttle vans (Toyota Hiace Grandia with D4D) the exhaust smells like a regular diesel engine.

Does anyone know what the difference is in terms of construction/design that might cause the difference?
