Toyota 1N / 1N-T

Toyota's 1N — a 1.5 diesel for small cars, and the turbocharged 1N-T beside it, in the Starlet and the diesel Tercel.

⚑ It is not an L-series and that is the whole difficulty. Toyota's famous small diesels are the 1L through 5L, they have their own page here, and they share no parts with this engine — but almost every search for a small Toyota diesel returns them. The N was built for a much smaller car and is a separate design.

A 1.5 diesel is a small engine by any standard, and its output is correspondingly modest; the turbocharged version exists because the naturally aspirated one was barely adequate.

Everything is mechanical — an injection pump, glow plugs, compression — and the belt is an interference design on cars now thirty years old.

It was sold in few markets and almost nothing about it exists in English. Japanese-market material is the practical source.
