Commutes Via Turbocharged Direct Injection

In General by Ronnie K2 Comments

After running a broad range of Diesel Engines over the years in a work environment, I was ecstatic to come across a reasonably priced Diesel 2000 Volkswagon Jetta TDI MK4. Owning a Diesel power car naturally lead me to do some research on the inner workings of my new commuter. With rising fuel costs and the fact that I usually put into high weekly mileage, owning a Diesel came with a large number of benefits. 2000-jetta-tdi-baltimoreThe TDI engine uses direct injection, where a fuel injector sprays atomised fuel directly into the main combustion chamber of each cylinder. TDI’s also make use of a Turbocharger in which a turbo charger unit compresses the oxygen that enters the chamber by way of force. Throwing a Turbo into the mix, a modern-day Turbo Diesel setup makes use of an intercooler, wherein the temperature of the compressed air in lowered, thus increasing the density of the already compressed incoming oxygen  It was interesting to read that older diesels used indirect injection. Making use of a pre-combustion chamber. Combining all of these mechanical variables is a matter of physics thus increasing engine efficiency. The result of this is  greater power outputs via a more complete combustion process, decreased emissions, increased torque and last but not least huge gains in fuel economy. Improved fuel economy also comes from  the actual physical makeup of diesel fuel itself. The Diesel Fuel’s efficient burn is related to the higher energy per-litre content and the intrinsic efficiency of the diesel engine as mentioned above.

  1. Great post. I used to be checking continuously this weblog and I am inspired! Very useful info specifically the last phase 🙂 I care for such info a lot. I was looking for this certain info for a long time. Thank you and best of luck.

    **Edit** Comment spam comes second nature when running a rss powered blog. I guess people still consider rel=nofollow link building worth the money. But I really got a kick out of this comment, no only is it proper & congruent English, the back-link is relevant to the article…it shows evidence that it was actually manually posted. Perhaps by a lone SEO grunt in Thailand. I say Thailand because the back link was pointing to a thailand based company distributing radiators! Quite frankly, it was the most exotic link spam build to cross my blogs. Well done LOL **
