DI and IDI Diesel Engine

Direct Injection (DI) and In-direct Injection (IDI) Diesel Engine construction and working

[@madcat4563]

Other people have said it before. But old videos really do explain stuff better.

[@aaronbalchand5475]

Who knew some video from the 80s or something would be a good starter to learning about diesels

[@bacilluscereus1299]

what is the date of this video? Did the heat loss get fixed?

[@staszeksowikowski9039]

As the speaker summarizes himself, following research allowed direct injection to be the most widely used. Im unaware of any idi diesels being in production for the last 25 years or so, at least not for automotive applications.

@@staszeksowikowski9039 here in indonesia indirect diesels are still widely used in new commercial cars up until 2022, and passenger cars up until 2000s

[@staszeksowikowski9039]

Anyone knows which manufacturer favored the prechamber rather than the swirl chamber?

[@TheKILLMANIA25]

Mercedes Benz

[@dadoVRC]

@@TheKILLMANIA25 Exactly, and the last pre-chamber images are MB ones!

[@rustychevy2087]

international idi diesel engines found in fords back in the day

[@compu85]

Yup - they used prechambers until the CDI engines came out around 2000!

[@ryanjohnson9325]

IdI is quiter lol, only when comparing a 1.8l idi to straight 6 10l+ di?

[@whitelightning5937]

The better comparison would be 7.3 idi bs 7.r power stroke

[@jasperdomacena6491]

😂😂 maybe they were comparing straight piped diesels to muffled diesels

[@benjaminturpin2749]

They absolutely are. All the mercedes idis are definitely quieter than the di. Same with all the ford diesel engines. It's at the very least a much less "sharp" sound with an idi

[@Ty4ons]

​@@benjaminturpin2749 Petrol direct injection is also noisier than port injection since the injectors have to be much higher pressure. Modern direct injection diesels are also doing a lot to mask that noise and are more silent in other areas, it would be interesting to hear how silent a modern IDI diesel could be.

[@dsimila1]

Yes or when comparing two popular tractor engines, Perkins A3.152 swirl chamber diesel or the direct injected AD3.152. These two are identical except head, piston and injectors. The older swirl chamber A3.152 model is quieter and has practically no knock. Another example would be late 1990:s Mitsubishi L200 compared to late 2010:s Mitsubishi L200, the later has a lot more knock.

Why DI is not used in high RPM vehicles

[@dineshbawane4255]

Infact DI used in all high speed (RPM) diesel car engines

[@Ty4ons]

Injectors weren’t good enough back then.

[@jannadrielcervo7753]

Only recently when we have common rail direct injection engines that can reach up to 2000 bar.

[@MrSipi1988]

@@jannadrielcervo7753 2000 bar, not psi

[@justmoonwithamustache]

Not true,IDI diesels are noisier than DI diesels due to uneven burning. DI are much quiter as they burn evenly

[@dineshbawane4255]

👍 true for modern engine... But low injection pressure and lower wall temperature in DI may result in longer delay and noisier combustion

[@drugbaba]

This video is old dude … don’t argue

[@bartholomausallen883]

Direct Injection is restricted to commercial vehicles? This is obviously about 25 years out-of-date.

[@dineshbawane4255]

Direct Injection technology is used in all diesel vehicles including passenger car, all CRDI engines are DI type.

[@whitelightning5937]

@@dineshbawane4255 not all diesel use idi there is a 6.9 and a 7.3 idi
