Many of not most auto and truck diesel engines made in recent years use 
electronic injection control. Instead of the familiar distribution-type 
injection 
pump with individual fuel lines to the injectors, there's a single high 
pressure fuel rail feeding all the injectors. The injectors are electronically 
controlled - which can be a source of RFI.

There's also a ton of other electronics on most modern vehicles, too.
