Diesel Engines

[USDMFTW]

Will diesel engines ever be added, or is it to much of a coding mess.

[Kubboz]

Yes, diesels will be one of the first things we'll have to consider for after release, but I would estimate that implementing diesels now would add about 6 months to development time... and asking people if they want their game early 2014 or late 2014, then I think people would prefer early 2014.

Also, they'd need a separate designer.

Diesels are a little bit available. Because the there is an Mechanical Injection But an real Diesel Injection is not here.
As i Know Diesel is allwasy an direct Injection.

direct diesel injection in cars appeared in the 90s. before that there was indirect injection; in which injection and start of combustion were taking place in the cylinder head in someting called a prechamber.
these were inefficient systems wasting a lot of heat , but were easy to manufacture and did not require great pressure to work and as a bonus allowed high rpms ,6000-6500 rpms on heavily modded engines could be achieved. they were also much quieter than modern diesels, having a distinct rumbling sound , much like a 2 stroke petrol.
