In a nutshell:"TD" = generic name for IDI (Indirect Diesel Injection) engine with a turbo- fuel is injected by a mechanically-controlled pump into a pre-combustion chamber in the head... hence the word "indirect".- first-gen diesel engine design... 1978ish to the mid 1990s, depending on what country you live in.- throttle is a standard lever and cable- cold start is a manual knob- glow plugs needed for even fairly warm starts, due to the large surface area of the pre-combustion chamber"TDI" = Turbo Direct Injection- fuel is injected by an electronically-controlled pump directly into the combustion chamber (a dished hole in the piston))...hence the word "direct"- second-gen diesel design... mid-1990s to 2003- throttle is drive-by-wire... no throttle cable- cold start is controlled by the ECU- glow plugs only needed for pretty cold starts- fuel efficiency better than IDIThree other flavors you'll read about:"mTDI": a (generally home-made) TDI pump that has been converted over to manual control to remove all dependancies on electronics"PD": Pumpe Duse design where each injector has a self-contained high pressure pump of its own driven off a camshaft. 2003ish-2006, again depending on where you live."common-rail": generic term used when describing current 3rd generation design (2007+) where the injectors are connected to a common rail fuel distribution that operates at extremely high pressures.Wikipedia has pretty good articles on this stuff as well.
isnt that basically the exact same thing i just said?and ive seen direct inject motors without turbos before...
My goodness this is an angry thread.Lets all sit back, take a deep breathe and crack open a beer
i'm pretty drunk. its awesome. i got drunk with no turbo on my car. its still awesome.
